Description

  The present invention relates to a technique for performing a change process, a point process, and a deposit process that occur at the time of exchange of money such as purchase of merchandise, money lending and borrowing. The present invention also relates to a technique for collecting when the use limit of the rewritable card is reached.

Conventionally, as one of various functions of the POS register, there is a function of returning discounts available at a later date or points for receiving a predetermined service corresponding to the purchase amount purchased by the customer. The rewards were given uniformly regardless of the frequency of customer visits and the purchase amount.
And each store was differentiated only by the reduction rate of the points to be given. For this reason, the only way to clearly differentiate from other stores was to increase the return rate, and the economic burden was high.

Therefore, the inventor determined in Japanese Patent Application No. 2002-49090, “It is determined whether or not change information is to be recorded, and when it is determined that change information is not recorded, the first point is recorded and change information is recorded. In some cases, a second premier point is generated, and the second premier point and change information are recorded. Invented others.
Japanese Patent Application 2002-49090

  That is, the customer changes the amount of change of a predetermined denomination or more in the change that occurs at the time of purchase of the product, returns the change in cash, records the change of less than the denomination on the card, and makes it available for the next purchase of the product. A customer card is issued by selecting in advance whether to issue a card, or to issue a point card that returns cash in cash every time it is settled. And when purchasing goods using a customer card, when changing the whole amount using a point card, the 1st point is given corresponding to the amount of goods purchased. The first point is given, for example, as 3% of the total amount of merchandise purchased, and recorded in other recording means corresponding to the point card itself or each point card.

  On the other hand, when a merchandise card is purchased using a change card, a change of a predetermined denomination, for example, less than 1000 yen, is recorded in another recording means corresponding to the change card itself or for each change card. Further, a second premier point is awarded for using the change card. That is, a point equivalent to 7% of the purchase amount, which is higher than the point return rate of 3% when using the point card, is given to other recording means corresponding to the change card itself or each change card as well as change. Record it.

  In this way, the usage rate of the change card by the customer can be increased by making the point return rate for the purchase amount different between when using the change card and when using the point card.

  As a result, for the customer, the change recorded on the change card can be used at the same store or affiliated stores from the next time onwards, so there is no particular disadvantage except that it cannot be used at other stores. Since the reward is given, the point reduction is good and advantageous by the difference between the first point and the second premier point, so there is a willingness to shop using a change card. This can promote the differentiation that stores are better than competing other stores.

  In addition, the store itself introduces a change card system, so that cash that should have been returned as change remains as a deposit at the store, and this deposit can be used effectively in terms of funds management. It was advantageous.

  However, in the conventional example, when the customer card is used to complete the accounting, once the customer card is inserted into the card reader / writer and it is determined whether the type of the customer card is a change card or a point card, If the change is less than the predetermined denomination, it will be recorded on the change card as a deposit, and the second premier point will be given. If it is a point card, the first point will be given without recording the change. Oops. Therefore, even though a change card is used, there is a problem that even if a change is desired to be received in cash, it cannot be dealt with.

  Further, there is a problem in that a customer who uses a point card cannot select a payment type in order to receive a payment as a change card after reconsidering the purchase of the product by selecting the payment using the point card.

  Furthermore, there has been nothing that a customer who uses a change card can freely set the maximum amount of change information as deposits recorded corresponding to the change card. In other words, some customers would like to record change of less than 1000 yen or desire to record change of less than 100 yen, but there was nothing to fulfill these hopes. This is because, for example, when the customer's age group has become younger due to a change in the product lineup, the maximum amount less than 100 yen is not appropriate as a deposit, so the maximum deposit is less than 100 yen. Corresponds to when you want to change. Similarly, there is a problem that the maximum amount of change information that can be recorded corresponding to the change card desired by the customer cannot be changed. Of course, there has been no change in the maximum value of these change information every predetermined date or every predetermined number of days.

  In addition, the total change information, which is the total deposit of the change information of all change cards, is equivalent to the self-issued type, so if it exceeds 7 million yen, it will be obliged to notify the competent bureau of the Ministry of Finance. The total amount of issuance must be reported on March 31 and September 30 every year, but these notifications and reports should be omitted if possible at the store. However, in the past, the total change information amount, which is the total deposit amount on the store side where the change information of all change cards has been accumulated, is monitored, and when the amount that requires a predetermined notification is reached, However, there was nothing that could be adjusted to be 7 million yen or less, so in some cases these reports and reports were required. Similarly, when closing a store or closing the account, there may be a case where the amount of total change information is set to 0. However, the amount of money that can be recorded as change information corresponding to the change card could not be adjusted. The amount could not be reduced to 0 yen.

In addition, the leuco-type or cloudy-type card has a limit of use of about 200 times, but the card must be used and the card in use can be collected at a predetermined number of times, which is the limit of service life. Isn't it possible?
Furthermore, in the conventional settlement apparatus, when manually inputting the prices of a plurality of products in the POS register or counting with a barcode reader, it is not possible to accept the payment unless the total price is determined. For this reason, it took a lot of time for counting and giving and receiving money, and there was much time for the next customer to wait.

  Furthermore, in the conventional automatic payment settlement system, a plurality of automatic payment settlement apparatuses are connected by a network that constructs a POS system, and information exchange between the automatic payment settlement apparatuses is independent of the POS system. It was not done. In other words, the software of the POS system is not normally disclosed, and it is possible to make corrections to the extent that some information such as product price information is transmitted through a local connection that connects one POS to one POS. Large-scale modification The modification of software on the POS system side requires high development costs, and such modification is not always undertaken. Also, the database structure of the POS system and the increase in recording capacity for the convenience of the checkout machine could not be added later to the POS system already sold. However, when changing information is recorded on a card and issued by a payment machine, there is a high risk of being counterfeited on the card, and it is necessary to manage the change information linked to the ID information on the payment machine side. In addition, in a shop where a plurality of payment machines are introduced, for example, in order to make it possible for a customer who has made a purchase one hour ago to use the changed payment information with another payment machine, it is necessary to share the changed payment information. was there. Moreover, it has the same problem as described above in the point information instead of the change information.

  In the present invention, in view of the above problems, even when a change card is used, it is possible to select whether the change is recorded on the change card or returned in cash. A payment method and a card payment device using a card that can be changed, and further, until the customer card is pulled out from the card reader / writer, the payment type selection that selects the change card can be changed to the payment type selection that selects the point card, A settlement method and settlement software capable of setting the maximum amount of change information recorded for each customer card and managing the total amount of change information recorded for each customer card Recorded recording medium and settlement apparatus, and further, a settlement method and a settlement medium on which settlement software can be received by a customer to receive a desired denomination Settlement device beauty, further an object to provide a sharable settlement device usage history related customer card among plural settlement apparatus independent of the network of POS systems.

    So this invention is

The change of less than a predetermined amount of change is recorded as change information corresponding to each ID, and the next step is to make a deposit that can be used as part of the purchase price at the time of settlement, and change other than the change is prohibited A settlement method characterized by having a step of rejecting with a denomination other than the denomination,
as well as,

A recording medium that records the settlement software, which is characterized by being returned with a denomination of
as well as,
A part of the change less than the predetermined amount is recorded as change information corresponding to each ID, and it is assumed as a deposit that can be used as part of the purchase price at the next settlement.
A recording medium on which payment software other than deposit money is returned with a denomination other than a change-prohibited denomination set for each ID;
as well as,
A change recording means that records a portion of the change less than a predetermined amount as change information corresponding to each ID, and is used as a deposit that can be used as part of the purchase price at the next settlement, and a change other than the deposit A settlement apparatus characterized by having a prohibited denomination change return means for returning with a denomination other than a change prohibited denomination,
as well as,
A change recording means that records a portion of the change less than a predetermined amount as change information corresponding to each ID, and makes a deposit that can be used as part of the purchase price at the time of settlement
A settlement apparatus characterized by having a prohibited denomination change return means for returning change other than deposit money with a denomination other than the change prohibited denomination set for each ID;

  I will provide a. Therefore, the customer records the portion of the change less than the predetermined amount as change information corresponding to the ID, and when the portion more than the predetermined amount is returned in cash, it is returned in the denomination excluding the change prohibited denomination. For example, if you don't want to use a 2,000-yen bill and you don't want to hold it, you can use a 2,000-yen bill as a prohibited money type. It is preferable because it will be returned in denominations other than.

  The ID is a medium such as a card or medal that identifies a medium lent or sold to a customer, a customer ID that can identify the customer itself, or the like, and the card itself may be an ID. In other words, it includes a method of reading an ID recorded on a magnetic tape or RFID with a card reader or RFID reader, reading and writing deposits and points from a recording area of a computer specified by the ID, or a personal identification number. The method of reading and writing deposits and points from the recording area of the computer specified by the ID, or if the computer does not have a recording area and the above ID code or deposit is not recorded, it is deposited on the inserted card itself When recording gold, there is a method of using the card itself as an ID. It is included in the present invention if deposits (which may include points) for each individual, each card, and each transaction can be identified when buying and selling. It is sufficient that the deposit is an ID that can be specified to be appropriable as a settlement fee after the next time.

  Therefore, according to the present invention, the user can select whether to return the change in cash or to record the portion less than the predetermined denomination of the change corresponding to the ID number of the customer card. You do not have to receive it as change. On the other hand, on the store side, it is possible to use the amount recorded as change as funds, since it can be used as cash equivalent when you visit the store again corresponding to each customer card without refunding the cash for change, Store management can be performed more smoothly.

  In addition, according to the present invention, the user can select whether to return the change in cash or to record the portion of the change less than the predetermined denomination corresponding to the ID of the customer card, Until the customer card is withdrawn, the change method can be selected again by the selection means, and even if the return method is selected by mistake, the return method can be changed until it is determined that the customer card has been withdrawn. .

  Similarly, the user can select whether to return the full amount of cash in cash or to record the portion of the change less than the predetermined denomination corresponding to the ID of the customer card. In addition, if the customer card used is a change card and there is no specific instruction, the change card can be automatically recorded and used as a change card. If the customer card is a point card and there is no specific instruction, the point card is automatically used. Can be used without recording change.

  Furthermore, according to the present invention, when the predetermined denomination for each customer card set in the customer card is higher than the predetermined upper limit predetermined denomination, the predetermined denomination for each customer is set as the upper limit predetermined denomination. It is possible to change the amount of deposits on the store side by all customer cards. Further, the predetermined denomination for each customer card can be automatically changed with a predetermined date. As a result, for example, when counterfeit cards are available, the upper limit predetermined denomination is reduced to 1 yen, etc., so that the merit of using the counterfeit card can be eliminated and eliminated. Furthermore, if the deposit is lost at the time of closing or closing the account, the total change information, which is the deposit recorded corresponding to all customer cards with the upper limit predetermined denomination set at 0 yen, is set to 0 yen. It becomes possible to approach. Furthermore, as a result of changing the product lineup, the customer's age group becomes younger, and if the deposit is less than 1000 yen, it can be changed to a deposit less than 100 yen. Further, the predetermined denomination for each customer card can be changed for each customer card based on the judgment of the store clerk, whereby only the desired card used can be changed.

  Furthermore, according to the present invention, since it is notified that the total amount of all customer cards of the change amount recorded for each customer card exceeds a predetermined amount, it is possible to adjust the store so that it does not have a deposit over a predetermined amount. In addition, since the store clerk can directly confirm that the total customer card total of the change amount recorded for each customer card exceeds the predetermined amount, the total customer card total amount of change recorded for each customer card is notified. Even if it is not done, the store clerk can check and it is possible to adjust the store appropriately so that it does not have a deposit over a predetermined amount. Furthermore, since it is possible to adjust the total deposit amount indicated by the total change information to be a predetermined amount, it is possible to adjust so that notification to the jurisdiction of the Ministry of Finance and reporting obligation do not occur.

  Furthermore, even for customer cards that use a short number of card storage and display means, such as leuco cards and cloudy cards, by setting a safe limit number in advance, you can select a card that has reached the limit number. Since it can be collected and a new customer card can be issued, the trouble of reissuing can be saved.

  Furthermore, since the settlement price from the customer can be accepted before the total purchase price of all the products to be purchased, the store clerk can accept the purchase price before scanning all the products, and the time required for the settlement can be shortened.

  Furthermore, by setting the change-prohibited denomination in advance, the change is not paid by the set denomination, so that the customer does not have to receive an undesired denomination as change.

  Furthermore, since the history information recording means is provided, and the automatic payment settlement apparatus and the history information recording means are connected by a network LAN 2 different from the POS network LAN 1, the automatic payment settlement system can be easily added to the existing POS system. Introduction cost can be reduced. Further, in the case where the history information recording means is provided in the automatic payment settlement apparatus, the installation location of the history information recording means may not be provided separately. Furthermore, history information recording means is provided in all automatic payment settlement apparatuses, so that even if there is a problem in the network LAN 2 connecting the automatic payment settlement apparatus, the history information of the customer card C can be recorded only by the automatic payment settlement apparatus here. Therefore, the restoration work of the network LAN 2 can be performed in parallel without stopping the business. By providing the network LAN 2 as described above, it is usually possible to share history information such as change information and point information without disclosing software of the POS system. In addition, large-scale modification of software on the POS system side does not require high development costs. Moreover, there is no need to always accept such corrections, the POS system's database structure for the convenience of the checkout machine, and the recording capacity increase cannot be added to the POS system that has already been sold. History information such as point information can be shared. If history information such as change information and point information can be shared in this way, when changing information is recorded on a card and issued by a settlement machine, it can be illegally converted because it can be verified by history information even if it is counterfeited on the card. It never happens. Further, in a store where a plurality of payment machines are introduced, for example, a customer who has made a purchase one hour ago can make use of the change information stored in the other payment machines.

  With reference to FIG. FIG. 1 is a configuration diagram of the entire automatic payment settlement system 1. In this automatic payment settlement system 1, a central management computer 2 that manages inventory status, a POS register 3 that is connected to the central management computer 2 and accounts for purchase prices, and a POS register 3 that is connected to a customer. Is connected to the central management computer 2 and sold by a settlement apparatus 4 that accepts a card inserted by the customer, can read and write information on the card, and can accept cash inserted by the customer and return change to the customer. POS terminal 5 that can manage the number of items at the sales floor, and a customer card C for carrying points such as points that are previously possessed by customers and given at the time of accounting. Among these devices, devices other than the settlement machine 4 can communicate with each other by constructing a POS system and connecting each other by a network for the POS system, and the plurality of settlement machines 4 are connected to the POS register 3. Thus, they are connected to each other by another network different from the network for the POS system, and are configured to be communicable.

  The central management computer 2 of the automatic payment settlement system 1 is not managed by a single computer, but actually comprises a plurality of computers. In other words, the central management computer 2 can transmit / receive data to / from the POS terminal 4 and can perform data transmission / reception on the product management, the POS register 3, and can also transmit / receive data to / from each POS register 3. If there are a plurality of computers or the like that manage the information of the customer card C used in the above, each function can be shared and executed, so that the processing speed is increased. Therefore, the central management computer 2 may be an aggregate of a plurality of computers, or a single computer may have all functions, and is not particularly limited in its configuration.

  The customer card C is composed of a card capable of recording information, such as a magnetic card and an IC card, but may be a recordable IC coin having a coin-like form and incorporating an IC. In this embodiment, the customer card C is a thin plate-like magnetic card similar to a telephone card. As shown in FIG. 2, the customer card C is provided with a magnetic recording unit C1 on the back surface, and information can be read and written by a reader / writer. A display unit C2 is provided on the surface of the customer card C. The display part C2 is provided as a window part so as to be visible on the front surface of the customer card C. The window part is formed in a window shape having a gap between the front surface and the back surface, and an appropriate amount of magnetic powder is included in the gap. Become. The magnetic powder contained is made of a color different from the background color. The display on the display unit C2 is performed by magnetically recording the back magnetic recording unit C1 facing the display unit C2 in a character or pattern corresponding to the display information, and shaking the customer card C in this state. The magnetic substance powder in the part C2 is moved and displayed while maintaining the state of being attached to the magnetized part of the magnetic recording part C1 by a magnetic force. Further, the display part C2 has a gap between the front surface and the back surface around the window-shaped opening so that extra magnetic powder other than the magnetic powder adhering to the magnetized part is Since it fits in the gap provided in the periphery by the angle generated when the card C is picked up, excess magnetic powder is not a concern in use. Furthermore, even if an impact is applied to the customer card C and the magnetic powder falls off the magnetized portion and the display cannot be visually recognized, if the customer card C is shaken to move the magnetic body inside the display portion C2, the customer card C is moved again. Attached to the magnetized portion and becomes visible.

  As the contents displayed on the display unit C2, for example, the previous transaction date / time, change amount, sex, and point balance are each displayed as a 12-digit serial number. If “02X12999F999” is displayed, the first 5 digits are displayed. “02X12” represents the previous transaction date 02X12 (02 represents 2002, X represents October, Y represents November, Z represents December, and 12 represents 12th), that is, “2002 10 Month 12 ”, the next three digits represent the change amount“ 999 yen ”, and the next one digit“ F ”represents the customer's gender (F represents female and M represents male). The subsequent three digits “999” represent “999 points” as the point balance. By displaying in this way, it is possible to prevent the store from misunderstanding that the previous memory of the change of the customer is ambiguous and the store has cheated the change. If the display area is allowed, more information may be displayed, and other information may be displayed. In the customer card C, the ID number set for each card, the assigned points, the type information indicating whether or not the change card can be used after the change is recorded, and the number of times the card is used are indicated. It is possible to record information on the number of times used and change information indicating the amount of change, but of course, necessary information other than these information, for example, secret information that only the customer using can know, customer name / address information, etc. Can also be recorded.

  In this embodiment, since the customer card C is a magnetic card and there is a problem with the confidentiality characteristic, only the ID number is recorded on the customer card C, and other information is associated with the ID number of the customer card C. Record in the automatic payment settlement system 1 on the store side. However, the customer's address and name that are not related to money, the history information that is the usage record at the time of visit, etc. may be recorded in the magnetic recording part C1 of the customer card C, and it has excellent confidentiality characteristics like an IC card. Some media may record more information.

  Also, the customer card C can use the customer card C as a point card CP that can use the first point given by the total amount used by the customer as a cash equivalent, and the settlement of the price. Sometimes the change that occurs as a fraction is recorded as change information in correspondence with the ID number of the customer card C, and the amount of change information can be used as cash equivalent at the next and subsequent payments, and depending on the total amount used by the customer In addition to the points to be awarded, the change can be used as a change card CC to which a premier point is given as a privilege by recording and using change corresponding to the ID number of the customer card C. Each point information and usage pattern can be recorded in the automatic payment system 1 corresponding to the ID number of the customer card C, and the information recorded in the automatic payment system 1 by reading the ID number of the customer card C. It can be determined whether the card is used as a point card CP or as a change card CC.

  When an IC card is used instead of a magnetic card, the IC card has a storage area of about 10 kbit at the maximum, so that the contents of the previously purchased item and the price for each purchase can be recorded in correspondence with the purchase date and time. For this reason, it is possible to prevent troubles caused by misunderstandings on the customer side with respect to the change deposits by displaying the price information for each purchase so as to be confirmed by the customer.

  The POS register 3 is composed of a register device used in the POS system, is installed in a settlement counter, and is communicably connected to the central management computer 2. The POS register 3 displays a key operation unit 31 for inputting a price or a barcode code number, a safe unit 32 for storing a purchase price received from a customer, a price of the purchased product, a cumulative price, etc. A possible price display unit 33, a barcode reader unit 34 capable of scanning the barcode of the purchased product, a handy reader unit 35 connected to the POS register 3 by an electric code and reading the barcode of the purchased product, and all purchased items It comprises a total end button 38 that is pressed by the store clerk when the merchandise is settled. Then, the price of the product purchased by the customer by the store clerk can be settled by calculating the purchase price by a method such as scanning a bar code or inputting the price and item by the key operation unit 31. Issue a receipt for the total amount. Of course, a storage device (not shown) is provided in the POS register 3 so that all data processed by the POS register 3 can be recorded together with the processing time. It is possible to record the time and the store attendant. In addition, the POS register 3 can always settle the price of the product to be settled to calculate the total price and send it to the settlement machine 4. 38 is pressed. Then, the fact that the sum of all the product prices has been completed by pressing the end button 38 is transmitted to the settlement machine 4.

  A plurality of key operation units 31 of the POS register 3 are provided on the surface of the POS register 3, and a type key for inputting a product type, a number key for inputting a numerical value such as a price of the product, a selection key for selecting a calculation type, and a subtotal. Subtotal key to calculate, total key to calculate total, change key to calculate change after entering the amount of money from customers, individual key to input the amount and type code of the corresponding product by pressing for each product, It consists of a type code relating to the product, such as a card operation key for reading or writing information to the customer card C, and a key that can be settled from the amount of the product and the deposit. The key operation unit 31 includes an instruction key for reading and writing to the customer card C when the customer card C is received, an issue key for issuing the customer card C, and the like.

  The safe unit 32 of the POS register 3 is provided inside the POS register 3 and can be opened by being pulled out to the front of the POS register 3 when the purchase price is deducted from the deposit of the key operation unit 31 and settled.

  The price display section 33 of the POS register 3 can display the name and price of the product and the accumulated price. Of course, other information may be displayed, and is displayed under the control of the control unit 37 of the POS register 3 (not shown because it is inside the POS register 3).

  The bar code reader unit 34 of the POS register 3 scans the bar code of the product to be purchased, and the POS register 3 can read the name and price of the product obtained from the bar code. Contributed to. That is, when the bar code reader unit 34 scans, the POS register 3 is controlled so that the addition work is automatically performed on the purchase price so far and the total is calculated.

  The handy reader unit 35 is connected to the POS register 3 by an electric cord so that a store clerk can hold it in his hand and read the barcode, and is formed to have the same function as the barcode reader unit 34.

  The POS register 3 includes a control unit 37. The control unit 37 controls each unit of the POS register 3 formed as described above, and is input from a bar code reader unit 34 or the like included in a normal register device. It is possible to output the same information of the purchased products to the central management computer 2 and read the ID number of the customer card C to meet the purchase price for the customer. It is possible to give points and give benefits commensurate with the points.

  As shown in FIG. 3, the checkout machine 4 receives the checkout money input from the customer, recognizes the amount of money, and accepts the customer card C inserted by the customer to receive the magnetic recording part C1 of the customer card C. A card reader / writer 42 that can read new information or information to be rewritten in the magnetic recording unit C1, a control unit 43 that controls the settlement machine 4, and a customer. A change payment unit 44 that automatically refunds cash, a display unit 45, a purchase button 46 (FIG. 1) for instructing the customer to finish payment and purchase, and a history that is card history storage means It comprises a storage unit 47 (not shown; semiconductor memory, made of hard disk), a change recording button 48 for instructing the change card CC to record change, and a change return button 49. The checkout machine 4 is connected to the POS register 3 so as to be able to input / output signals, and can receive and input individual charges purchased by the customer, total prices of the purchases purchased by the customer calculated by the POS register 3, etc. The information recorded in C, the denomination and amount paid to the settlement machine 4 by the customer, the total amount paid, etc. can be output to the POS register 3.

  A plurality of payment machines 4 are connected to each other by a network LAN 2 different from the network LAN 1 (POS network) constructed by the POS system. In this way, the settlement machines 4 are connected to each other by the network LAN 2 different from the POS network LAN 1, so that the settlement machines 4 can exchange information without passing through the POS system. As a result, for example, by connecting the settlement machine 4 to the POS register 3 of the existing POS system, the signal that the existing POS register 3 can output from the POS register 3, such as calculation information of the total price including information on the purchase price calculation process. In addition, the automatic payment settlement system 1 can be constructed in the existing POS system 1 by outputting the information that payment is completed to the settlement machine 4 and the settlement completion is output to the POS register 3. However, when a new automatic payment settlement system 1 is constructed, the settlement machines 4 may exchange information via the POS network LAN 1.

  The cash accepting unit 41 of the settlement machine 4 is used when the customer pays the purchase price of the customer settled by the POS register 3 to the settlement machine 4, and receives the cash inserted from the cash input slot and conveys it to the identification unit. Thus, the cash amount can be identified, the amount can be temporarily recorded in the control unit 43, and the accepted cash can be stored. Then, it is possible to sequentially accept cash, and the sequentially accepted cash can be recorded again after adding the amount temporarily recorded after identifying the amount. Therefore, the cash accepting unit 41 can recognize the amount of money paid from the customer.

  The card reader / writer 42 of the checkout machine 4 can write and read information on the customer card C inserted by the customer in accordance with an instruction from the control unit 43. Further, the card reader / writer 42 inputs a card issuance instruction signal so that the inserted customer card C is not only point information but also the inserted customer card C is a point card CP. The customer card C functions as a change card CC at the request of the customer, and the information necessary to function as a new customer card C is recorded in correspondence with the ID number of the customer card C and the customer card C is issued. It has a function. When the customer card C is inserted, the card reader / writer 42 reads each information such as the ID number of the customer card C recorded on the customer card C, and reads the information read into the temporary storage area prepared in the checkout machine 4. Output and store each information. In this embodiment, the card reader / writer 42 is configured to read the recorded information when the customer card C is inserted. However, the card reader / writer 42 reads the necessary information when necessary according to an instruction from the control unit 43. It may be formed.

  The control unit 43 of the checkout machine 4 waits for the card reader / writer 42 and the card read / write control when the customer card C is inserted, waits for the cash accepting unit 41 to be inserted, and cash input when the cash is inserted. Instructions by control signals to each unit such as total calculation, change payment instruction to the change payment unit 44, display control of various information on the display unit 45, and the like are possible. The control unit 43 controls each unit of the settlement machine 4 formed as described above, and displays a signal input from the POS register 3 on the display unit 45, or the cash underwriting unit as the amount of cash accepted by the cash underwriting unit 41. Send the amount paid to 41 to the POS register 3 or read and write to the customer card C to give the customer a point corresponding to the purchase amount and give a privilege corresponding to the point Is possible.

  The change payment unit 44 of the checkout machine 4 can automatically pay the amount of change to be paid to the customer, and the operation and payment amount can be appropriately operated and returned depending on the amount received from the control unit 43. is there.

  The display unit 45 of the checkout machine 4 is the same as the price display unit 33 of the POS register 3, displays the name and price of the product, can display the accumulated price, and further, the price to be paid by the customer and the change amount to be paid. Various information can be displayed such as prompting the customer to insert the point card CP or the change card CC. Of course, other information may be displayed, and is displayed under the control of the control unit 43 or the control unit 37 of the POS register 3. In this embodiment, the display unit 45 is provided in the checkout machine 4, but the price display unit 33 provided in the POS register 3 connected to the checkout machine 4 may be used as the display unit 45. The unit 33 is formed so that the display unit 45 can display in addition to the display unit 33 described above.

  The purchase button 46 is a push button switch that is pressed by the customer after the total price of the purchased product is deposited in the cash underwriting unit 41 and displays the willingness of the customer to purchase the product by adjusting the purchase price.

  The history storage unit 47 is a recording device, and can record a use history using the customer card C inserted into the card reader / writer 42. In this embodiment, the history storage unit 47 is provided in each of the checkout machines 4. The history storage unit 47 provided in each settlement machine 4 reads and writes change information and point information to and from the customer card C inserted into the card reader / writer by all the settlement machines 4 connected via the network LAN 2. The history can be recorded through the network LAN 2 each time. Specifically, the history information is made up of various types of information as shown by the item “name” in FIG. 15, for example, “card ID” for identifying the customer card C, “transaction type” specifying the type of transaction. "Flag", "Transaction date / time" indicating the date of the transaction performed, "Transaction points" after being generated or consumed at the time of transaction, "Current point increase rate" indicating the rate of increase / decrease in the transaction , “Point grant correction factor flag” for adjusting the point occurrence rate of points to be given, “card balance” representing change information recorded corresponding to the customer card C, “total price” representing the purchase price traded, “Payment amount” received at the time of settlement, “Return money details 10,000 yen” indicating the number of 10,000 yen bills returned as change, “Return money details 5,000 yen”, “Return money details 2,000 yen” , "Refund details 1,000 yen", "Return" "Details of 500 yen", "Return money details of 100 yen", "Return money details of 50 yen", "Return money details of 10 yen", "Return money details of 5 yen", "Return money details of 1 yen" , "Deposit details 10,000 yen", "Deposit details 5,000 yen", "Deposit details 2,000 yen", "Deposit details 1,000 yen", representing the number of 10,000 yen bills deposited, returned in cash "Return change amount" indicating the amount of change made, "Error code" explaining an error that occurred during the transaction, etc., and this information is recorded in correspondence with the ID number of the customer card C. There is an expiration date of points recorded in correspondence with the customer card C, various data that become correction factors when points are generated, and the like. These pieces of information are recorded in time series. By installing the history recording unit 47 in all the checkout machines 4 in this way, the checkout machine 4 can store the history information of the customer card C without going through the network LAN 1 of the POS system when the customer card C is inserted. Since the information can be recorded, the information of the customer card C into which the individual settlement machines 4 are inserted can be recorded even if communication via the network LAN 1 becomes impossible. Therefore, the automatic payment settlement system 1 can be operated without stopping.

  In this embodiment, the history storage unit 47, which is a card history storage means, is provided in the checkout machine 4, but is provided separately from the checkout machine 4 and connected to the network LAN 2 so that the customer card C The history information of the customer card C requested by the inquiry request from the settlement machine 4 may be output. In this case, since the configuration of the settlement machine 4 is simplified, the construction cost of the automatic payment settlement system 1 is not required.

  Further, among the payment machines 4 connected to the network LAN 2, the automatic payment system 1 may be constructed by incorporating the history storage unit 47 in one payment machine 4. As described above, the history storage unit 47 is built in the checkout machine 4 so that a place for installing the history storage unit 47 is not required.

  Next, the operation when the history storage unit 47 is provided in all the checkout machines 4 will be described with reference to FIG.

  The flowchart shown in FIG. 13 represents the processing of the history of the customer card C being processed by the settlement machine 4 and the history of the customer card C being processed by another settlement machine 4. That is, it includes a history update step NN150, a data update determination step NN151, a data reception step NN152, and a data transmission step NN153. The history update step NN150 through the data transmission step NN153 are always repeated.

  First, when history information to be recorded is calculated by the control unit 43 of the settlement machine 4, a pointer (relative address or the like) and contents of the history information are written in the working RAM. This working RAM is programmed to be recorded in a free space next to the already written memory in a continuous memory space until the pointer and contents are cleared by the history update step NN150.

  In the history update step NN150, all memory areas of the working RAM are searched. If there is new history information in each area, that is, if the pointer is not 0XFFFFFF, the new history information is recorded in the memory area of the history information recording unit 47 specified by the pointer and recorded in the transmission stack memory. Then, the working RAM is cleared.

  The data update determination step NN151 is executed following the history update step NN150, and new history information is generated in the other settlement machine 4 or there is new history information in the customer card C processed by itself (transmission) This is a step for determining whether or not the stack memory is not empty. When new card history information is received from the other settlement machine 4, the data reception step NN152 is subsequently executed and recorded in the memory area of the history information recording unit 47 specified by the pointer transmitted at the same time. If there is new card history information in the customer card C being processed, the data transmission step NN153 is subsequently executed, and all the contents of the transmission stack memory are sequentially transmitted to the other settlement machines 4 and the POS register 3. And then clear. If there is nothing, the history update step NN150 is executed again. Therefore, when there is no new card history information, the same information is always updated by the history update step NN150. Note that it is preferable to perform the steps NN150 to NN153 by providing a network control unit driven by a CPU other than the control unit 43 of the settlement machine 4 because the processing speed of the settlement machine 4 is increased.

  The change record button 48 is provided to determine whether or not the change machine 4 records change according to the ID number of the customer card C in the change record determination step S31. 4 indicates that the history recording unit 47 records that the customer card C is used as the change card CC, and a signal for determining that it is an instruction to record the change in the history recording unit 47 corresponding to the ID number of the customer card C. Output to the control unit 43.

  The change return button 49 is provided for the settlement machine 4 to determine whether the change is recorded in the history recording unit 47 in correspondence with the ID number of the customer card C in the change record determination step S31 like the change record button 48. When the customer presses, the checkout machine 4 records the fact that the customer card C is used as the point card CP in the history recording unit 47, and changes the change corresponding to the ID number of the customer card C in the history recording unit 47. A signal for determining that the instruction is not to be recorded is output to the control unit 43.

  In this embodiment, the card reader / writer 42 is installed in the checkout machine 4, and the payment by the customer can be made by the checkout machine 4. However, the card reader / writer is installed according to the environment in which the store is used. Can be set. For example, in this embodiment, when a cashier becomes unsanitary by holding cash in a store that handles food such as a fast food restaurant, the cashier gives the total amount of purchased products. In order to calculate, the price of each item is input to the POS register 3 by the barcode reader unit 34 or the like to calculate the total purchase price. The customer directly inserts the customer card C and pays the price to the checkout machine 4. When performing, the safe unit 32 is not necessary for the POS register 3, and it is sufficient to form the POS register 3 from the key operation unit 31, the price display unit 33, the barcode reader unit 34, and the handy reader unit 35. For example, as shown in FIG. 4, the cash settlement unit 4 is not provided in the checkout machine 4, and a card reader / writer 42, a control unit 43, a change payment unit 44, and a display unit 45 are provided (display unit 45). However, the customer may only insert the customer card C into the checkout machine 4, and the cashier only deposits the cash from the customer and deposits it into the safe 32, and delivers the change. You may comprise so that the mistake which may be performed by the checkout machine 4 and mistakenly delivered the amount of change which generate | occur | produces frequently at the time of change delivery may be prevented. As described above, the configurations of the POS register 3 and the settlement machine 4 may be changed according to the use environment of the POS system 1, and by using the changed POS system 1, a better use of the POS system 1 becomes possible. Furthermore, the card reader / writer 36 corresponding to the customer card C only for recording the points used from the past, which is a magnetic card, is provided in the POS register 3, and the card reader / writer 42 of the checkout machine 4 is used as a new customer. By forming the card C so as to correspond to the point card CP capable of recording points and the change card CC capable of recording the points and the change information CC, the old customer card can be formed. C and new customer card C can be used, and when the customer card C that can record change can be introduced, the POS register 3 that has been used from the past can be used, and can be introduced without introducing installation costs. Become.

  The details of the point provision provided to the customer when paying with the POS register 3 will be described below based on the flowchart shown in FIG. Note that the information used for the determination made in each step is based on information read from the customer card C by the card reader / writer 42, unless otherwise specified. Similarly, in the case of recording on the customer card C, unless otherwise specified, it is newly recorded on the customer card C by the card reader / writer 42 (overwrite recording is performed when the same recording already exists).

  5 to 7 show flowcharts of the point and change information recording process. F is a point and change information recording process. In the POS register 3, a card confirmation process S is executed.

  That is, the card confirmation processing S is started when the customer card C is inserted into the card reader / writer 36 or when the customer requests card issuance by pressing a predetermined switch. The card confirmation process S includes a card insertion determination step S1, a card issuance step S2, a usage count determination step S3, and a usage count addition step S4.

  The card insertion determination step S1 is a step of determining whether or not the customer has presented the customer card C and whether or not the card has been inserted into the card reader / writer 36 by the store clerk or by the customer. Information received from the card reader / writer 36 Judgment by. In the card insertion determination step S1, when the customer card C is inserted, the use count determination step S3 is executed, and when there is no insertion, the card issuance step S2 is executed.

  Note that the card insertion determination step S1 may be formed such that the old card can be abolished and the new card can be transferred as shown in FIG. 8. In this case, the card insertion determination step S1 is followed by S111. Thru | or S113 are provided and each step is performed. That is, S111 is a card discrimination step. The card determination step S111 can determine whether or not the inserted customer card C is an old point card. In the card determination step S111, when the customer card C is an old point card, the point reading and discard processing step S112 is subsequently executed. Further, in the card determination step S111, when it is determined that the inserted customer card C is not an old point card, the use count determination step S3 is subsequently executed.

  In the point reading and discarding step S112, the point information is read from the inserted customer card C, and the inserted old point card can be abolished. Subsequent to the point reading and discarding processing step S112, the issuing step S113 is executed.

  The issuing step S113 can issue a customer card C that can record both change and points in the present invention in place of the old customer card C. Here, the store clerk confirms the customer's request, and by pressing each selection button to select whether the point card CP is a point card CP that records only points or a change card CC that can record change in addition to points, A card CP or a change card CC can be selected. The points recorded on the customer card C, which is the old point card that has been read, are recorded on the customer card C that is newly issued here, and the issuance of a new customer card C completes the response to the new device. Takeover is completed. Subsequent to the issuing step S113, the settlement determining step S5 is executed.

  Here, the case where the customer card C which is the old point card is transferred to the customer card C which is the new card has been described. However, the old point card and the customer card C which can record both the newly issued change and points are as follows. May be made available. In this case, point reading step S10, point consumption step S12, premier point calculating step S28, point calculating step S30, premier point calculating step S33, point calculating step S35, recording step S37, point reading step S45, premier point calculating, which will be described later. In addition to the functions of step S61 and point recording step S62, the following functions are added. Details will be described later.

  In the card issuance step S2, card issuance is instructed, and the card reader / writer 36 receives predetermined information from the control unit 37 and issues a new customer card C. Details of the customer card C issuance will be described separately.

  In the usage number determination step S3, it is determined whether or not the usage number information stored in the inserted customer card C is less than the usage limit. If it is executed and it is determined that it is less than the use limit, the use number adding step S4 is executed subsequently. In the case of leuco and cloudy rewrite cards, the limit of use reaches the limit of use with a rewrite number of about 200 times. Therefore, when these card types are used, the use limit number is set to 200 in advance, and it is monitored whether or not the use limit number is reached in the use number determination step S3, and the customer card C uses it. A new customer card C can be issued before it becomes impossible.

  The limit number of times of use may be accurately counted as the number of rewrites, but since the number of times of rewrite can be predicted according to the number of times of shopping and insertion into the card reader / writer, One should be used.

  In the use count addition step S4, 1 is added to the use count read from the customer card C, and the added new use count is recorded in the customer card C. Subsequent to the use count addition step S4, a settlement determination step S5 is executed.

  In this way, in the card confirmation process S, the customer card C is issued to the customer who does not have the customer card C, and the usage limit of the customer card C is monitored. If it is too long, the customer card C is collected and the new customer card C is instructed to record and issue the information recorded in the customer card C that has reached the limit of use. In addition, when the display unit is a heat sensitive leuco type or heat sensitive cloudy type, the card can be used up to a maximum number of times the card can be used to prevent troubles with customers and stores due to card damage. It can be prevented. The customer card C that has reached the usage limit can be collected by preparing a card stacker that can collect the card in the card reader / writer 36 or in the device in which the card reader / writer 36 is stored, or collecting the card. The card reader / writer 36 is provided with a card insertion / discharge port on the customer side and a card discharge port on the clerk side opposite to the customer side, and the customer card C before the use limit is placed on the customer side. The customer card C discharged from the outlet to the customer side and reaching the use limit may be discharged from the card outlet provided on the store clerk side and collected by the store clerk.

  The settlement determination step S5 is a step for determining a customer settlement method. The determination performed in the payment determination step S5 is a step of determining whether to make a payment using the customer card C or to simply change the contents of the customer card C. If it is determined in the payment determination step S5 that the payment is a normal payment (settlement at the time of shopping), a total amount input step S7 is executed, and when a change from the normal customer card C to a change card is desired. The card insertion determination step S41 is performed in which a history flag indicating whether or not the first customer card C determined in the card insertion determination step S1 has been inserted is executed. Therefore, when it is determined that the payment is a normal payment in the payment determination step S5, the inserted or newly issued customer card C may be used as a normal point card CP or a change card CC. . In this embodiment, as a determination made in the payment determination step S5, the normal payment is a case where a “price payment button” (not shown) is pressed, and the change process is a “change to a change card member” button ( This is a case where (not shown) is pressed. Here, four types of buttons are provided adjacent to the liquid crystal screen and the screen, and the four types of functions are displayed on a part of the liquid crystal screen closest to each other to provide four or more types of button functions. You may comprise as follows.

  The change information determination step S7 is a step of determining whether change information is stored corresponding to the ID number of the customer card C. When the change information determination step S7 determines that there is no change information, the change information replacement step S8 is subsequently executed, and when it is determined that change information is present, the change information reading step S9 is subsequently executed. Let Accordingly, in the change information determination step S7, the next step to be performed differs depending on the customer card C being used. Executed.

  The change information replacement step S8 is a step performed when the customer card C being used is a normal point card CP, and since there is no change information recorded corresponding to the ID number in the point card CP, This is a step of storing a change amount of 0 yen in the change card balance of the working RAM for use in later calculations.

  The change information reading step S9 is a step executed when there is change information, that is, when the customer card C being used is the change card CC. In the change information reading step S9, the change information recorded corresponding to the ID number of the customer card C is read as a usable change amount.

  The point reading step S10 is executed subsequent to the change information replacement step S8 or the change information reading step S9, and the point information recorded corresponding to the ID number of the customer card C is used for later calculation. This is a step of recording in the working RAM “oldpt”. The points read in the point reading step S10 can be used as a part of the settlement fee.

  The point consumption desire determination step S11 is executed following the point reading step S10. The point consumption desire determination step S11 is a step of determining whether or not the customer wants to use points. When the store clerk presses a predetermined key of the POS register 3, the pressed information is held and the point consumption desire determination is performed. In step S11, it is determined that point consumption is desired. In the point consumption desire determination step S11, when it is determined that the point consumption is desired, the point consumption step S12 is continuously executed, and when it is determined that the point consumption is not desired, the settlement price calculation step S13 is continuously executed. . In the point consumption request determination step S11, it is preferable that the store clerk asks the customer or displays “Would you like to spend points?” And waits for the YES or NO button to be pressed. Further, when the customer card C is inserted into the card reader / writer 36 or the card reader / writer 42, points may be automatically consumed. In this case, at the change information determination step S7, the customer card C is used. It may be determined whether or not C has been inserted. Further, the point consumption step S12 may be executed after the point reading step S10 without providing the point consumption desire determination step S11 so that points are always consumed.

  The point consumption step S12 is a step for setting the points read in the point reading step S10 to be used for the payment. With point consumption, read points are converted into discounts. In this case, the point to be consumed is the full amount, but the desired amount of the point to be consumed may be input to be a part. In addition, the privilege by points may be discounted as in the present embodiment, but other prizes may be given to reduce the points for the prizes.

  The settlement price display step S16 is a step for displaying the unsettled amount (s) on the display unit 45 and the price display unit 33. Accordingly, the display unit 45 and the price display unit 33 are formed so as to be able to display the amount calculated in the settlement price display step S16.

  When the settlement price display step S16 is completed, a deposit acceptance step S17 is executed. The payment acceptance step S17 is a step of waiting for the payment of the unsettled price from the customer and inputting and updating the total price of the price purchased for the prize from the POS register 3. In this embodiment, the customer pays the settlement machine. Since the purchase price is sequentially inserted from the POS register, the remaining amount obtained by subtracting the received price is displayed on the display unit 45 each time. . In addition, in the deposit acceptance step S17, processing is performed so that the total amount is always transmitted and updated by the POS register 3, so that even if the POS register 3 has settled the purchase price, it is possible to accept the deposit of the unsettled portion by the customer. It is.

  The deposit acceptance step S17 is formed by a deposit acceptance step S171 for accepting the deposit by the cash accepting unit 41, a settlement price calculation step S172 for calculating the unsettled amount (s) after the deposit, and a deposit end determination step S173.

  The deposit acceptance step S171 is a step of recognizing the amount of bills or coins directly inserted into the cash underwriting unit 41 provided separately by the customer as the deposit amount, and the settlement price calculation step S172 is subsequently executed.

  In the settlement price calculation step S172, the total price, which is the price to be settled, input from the POS register 3 is settled by the received price and the point amount calculated in the point settlement step S12, and the unsettled price is further calculated. This is a calculating step. That is, in the settlement price calculation step S172, the total price calculated by the POS register 3 is always input. This total price to be settled includes the intermediate settlement in the process where the POS register 3 gives the total amount of all purchased products, and even during the POS register 3 reading and calculating the product barcode, The price calculation step S172 always inputs the total price. Then, in the settlement price calculation step S172, the amount received in the deposit acceptance step S171 and the discount amount calculated in the point settlement step S12 are subtracted from the total price, and an unsettled amount (surplus price) is set as a new settlement price to be settled. ) This is a step for calculating s, and subsequently, a deposit end judging step S173 is executed. The unsettled amount (surplus amount) s, which is the new settlement price to be settled calculated in the settlement price calculation step S172, is updated and stored in the settlement price to be settled calculated in the point settlement step S12. It may be replaced and temporarily stored, or may be temporarily stored separately.

  In the payment end determination step S173, it is determined whether or not there is a new payment price to be paid calculated in the payment price calculation step S172. That is, it is monitored whether there is no unsettled amount (surplus amount) s (settlement price is 0 or more), settlement in the POS register 3 is completed, and whether the customer's payment is completed. When the amount (surplus amount) s does not exist (the settlement price is 0 or more), the settlement in the POS register 3 is completed, and the purchase button 46 is pressed to complete the customer's payment, that is, the POS register In step 3, the total end button 38 is pressed to complete the processing of all the products, and the total price is input. The purchase button 46 is pressed by the customer to finish the insertion of cash, and all the prices to be settled are settled. If the unpaid amount is 0 or more, the money type amount setting step S18 is subsequently executed to check whether there is an unpaid amount (s) (the settlement price is 0 or less). Total end button 38 is pressed Or has not been completed settlement not, in the case of either payment of the customer is to be confirmed not completed by pressing the buy button 46, to execute a settlement price display step S16 again. If all the payments to be settled have been settled (the unsettled amount is 0 or more), then the money type amount setting step S18 is executed. In addition, when the amount of money deposited by the customer is insufficient and the payment completion determination step S17 executes the settlement price display step S16 again, the display unit 45 is displayed so that it can be seen that the amount of money to be charged is small.

  In this way, the deposit acceptance step S17 allows the receipt of the deposit from the customer even while the POS register 3 is paying out the total price of all commodities. In addition, although the payment of the unsettled amount (s) is completed in the deposit acceptance step S17, the money type amount setting step S18 is executed. The settlement amount (s) represents the amount to be surplus and returned as change. In the settlement price display step S16, a signal is output so that the latest unsettled amount (s) is always displayed.

  In this embodiment, the confirmation input for instructing the settlement includes both a total end instruction for the POS register 3 by pressing the total end button 38 and an instruction for completing the customer's cash insertion by pressing the purchase button 46. Although satisfied, it may be either by pressing the total end button 38 of the POS register 3 or pressing the purchase button 46 of the payment machine 4. Of course, the confirmation input may be performed by confirming the will of both parties through a conversation between the store clerk operating the POS register 3 and the customer and pressing a push button switch or the like.

  In the denomination amount setting step S18, the predetermined denomination is set to 10,000 yen and 10,000 yen, 5,000 yen, 2,000 yen, 1,000 yen, 5 hundred yen, 1 hundred yen, 50 yen, 10 yen, This is a step of setting each denomination (i) of 5 yen and 1 yen to 0, that is, 10,000 yen, and setting a return number N for each denomination (i) to 0, followed by a predetermined denomination determination step S19 is executed. In the denomination (i), i = 0 represents 10,000 yen, i = 1 represents 5,000 yen, i = 2 represents 1,000 yen, i = 3 represents 500 yen, i = 4 Represents 1 hundred yen, i = 5 represents 50 yen, i = 6 represents 10 yen, i = 7 represents 5 yen, and i = 8 represents 1 yen. N represents the number of sheets, and is represented by a natural number such as N = 0, 1, 2, 3, 4,. Accordingly, the return number N [i] represents, for example, that the return number 3 [2] when i = 2 and N = 3 is three thousand yen, that is, 3000 yen. The predetermined denomination represents how much change is recorded and returned in correspondence with the ID number of the change card CC when the customer receives the change. For example, the predetermined denomination is 1000. If it is a yen, a change of less than 1000 yen, that is, a change of up to 999 yen is recorded as change information corresponding to the ID number of the change card CC.

  The predetermined denomination determining step S19 compares the upper limit predetermined denomination with the predetermined denomination for each customer, and if the predetermined denomination for each customer is larger than the upper limit predetermined denomination, the predetermined denomination setting step S20 is executed, otherwise In this case, change payment determination step S21 is executed. Here, the predetermined denomination per customer means the upper limit that the customer may record as change corresponding to the ID number of the change card CC. For example, if the predetermined denomination per customer is 1000 yen The maximum amount stored in correspondence with the ID number of the change card CC as change is less than 1000 yen. Is stored as change information corresponding to the ID number. Similarly, the upper limit predetermined denomination is a predetermined denomination that specifies the upper limit of the change amount when the store side records the change on the customer card C, and the upper limit predetermined denomination is adjusted to the ID number of the change card CC. By adjusting the upper limit of the change information to be recorded correspondingly, it is possible to adjust to some extent the amount issued as change by the store side from all change card CC users, that is, the amount deposited. And the upper limit predetermined denomination is a denomination that is commonly set for each settlement machine 4 and is normally set to 5,000 yen, but the amount deposited by all change cards CC is not less than the predetermined amount. For example, the total deposit amount of all change cards CC will be over 7 million yen, which requires the notification to each jurisdiction station established in each region of the Ministry of Finance. In that case, the upper limit predetermined denomination is lowered to a predetermined denomination such as 500 yen. Thus, when the change information is recorded corresponding to the ID number of the change card CC thereafter, the predetermined denomination for each customer is replaced with the upper limit predetermined denomination in the subsequent predetermined denomination setting step S20. After a predetermined period, it is possible to reduce the total deposit amount of all change cards CC.

  In the predetermined denomination setting step S20, since the predetermined denomination per customer is determined to be larger than the upper limit predetermined denomination in the predetermined denomination determining step S19, the predetermined denomination per customer recorded corresponding to the ID number of the change card CC is determined. This is a step of setting the denomination to the upper limit predetermined denomination, and then a change payment determination step S21 is executed. In this way, the predetermined denomination setting step S20 sets the predetermined denomination for each customer so that it does not become larger when the change process is performed than the upper limit predetermined denomination set by the store. When the total amount of change card CC deposits, which is a reporting obligation, exceeds 7 million yen, change the denomination of the upper limit predetermined denomination to the predetermined denomination, and increase the change amount to be returned in cash The amount of change information recorded corresponding to the ID number of the card CC can be reduced so that the total deposit amount can be adjusted to 7 million yen or less. The change of the predetermined denomination for each customer is effective on the card recognition process S and does not rewrite the predetermined denomination for each customer recorded in the change card CC. The predetermined denomination is read by the card reader / writer 42 as it is. Note that the predetermined denomination for each customer can be set to any denomination by the customer's offer when the change card CC is issued, and can be rewritten when the customer wishes to change the predetermined denomination for each customer. The details of the rewriting are not described in detail because they are written on a general card.

The upper limit predetermined denomination determined by the predetermined denomination determination step S19 is specified in advance in the central management computer 2 and the upper limit predetermined denomination determined by the predetermined denomination determination step S19 is determined in advance from the predetermined date before the predetermined date. A determination may be made by comparing the denomination per customer with the denomination, and if the predetermined denomination per customer is larger, the predetermined denomination setting step S20 may be used to rewrite the upper limit predetermined denomination. That is, for example, the central management computer 2 sets March 31 and September 30 as the predetermined dates, specifies 10 days before the predetermined date, and specifies the upper limit predetermined denomination as 100 yen. Keep it. Then, in the setting of March 31, the upper limit predetermined denomination compared by the predetermined denomination determination step S19 from March 21st, that is, from March 21, is set to 100 yen for all the settlement machines 4. The Similarly, even in the setting for September 30, the upper limit predetermined denomination compared by the predetermined denomination determination step S19 from September 20 is set to 100 yen for all the checkout machines 4. Thereby, after March 21 or September 20, the predetermined denomination determination step S19 compares the upper limit predetermined denomination as 100 yen and cancels the predetermined denomination for each customer until these settings are canceled. If this is larger, the predetermined denomination per customer is recorded as 100 yen in the predetermined denomination setting step S20. The customer card C itself may be recorded at this time, or a recording area or a recording device provided in advance in the central management computer 2 or the like corresponding to each customer card.
In this way, by changing the predetermined denomination for each customer according to the predetermined date, it is possible to adjust the total change amount recorded on all the customer cards C on the predetermined date.

  Further, in the determination in the predetermined denomination determining step S19, the store clerk determines whether or not to rewrite the predetermined denomination per customer on the customer card C, and rewrites the predetermined denomination per customer by manual input by key operation. Also good. That is, a predetermined denomination for each customer recorded corresponding to the ID number of the customer card C read in advance by the card reader / writer 42 is read and displayed on the price display unit 33 of the POS register 3 in the settlement price display step S16. To do. Then, when the store clerk makes a judgment by looking at the predetermined denomination for each customer and rewrites the predetermined denomination for each customer, a rewrite input button (not shown) provided in advance in the key operation unit 31 is pressed, and the rewrite input button is pressed. In this case, the predetermined denomination determining step S19 is determined as YES, and then the predetermined denomination setting step S20 is executed. You may form so that it may record corresponding to ID number of customer card C as a denomination.

  As described above, since the predetermined denomination for each customer can be changed by the key operation of the store clerk, the predetermined denomination for each customer can be changed without using the central management computer 2, and the program of the central management computer 2 does not need to be changed.

  In addition, the change of the upper limit predetermined denomination may be made so that the total amount of change information, which is the deposit recorded corresponding to the ID numbers of all the customer cards C, does not become larger than the predetermined upper limit deposit total. good. That is, a process is provided for controlling the total amount of deposits required to be notified to the Ministry of Finance not to exceed 7 million yen. Furthermore, it may be notified that the total amount of deposits has approached an amount that should not exceed.

  Hereinafter, a process for controlling the total deposit amount and a process for notifying that the total deposit amount should not exceed will be described with reference to FIG.

  S63 is a total amount calculation step, and calculates the total amount of change information which is a deposit recorded corresponding to all the customer cards C.

  S64 is a notification determination step, which is executed subsequent to the total amount calculation step S63, and is a step for determining whether or not the total amount of change information calculated in the total amount calculation step S63 has reached a predetermined notification amount. Therefore, in the notification determination step S64, a notification limit amount to be compared with the total amount of change information calculated in the total amount calculation step S63 is set in advance. In this embodiment, the notification limit is 6.5 million yen, but can be changed to a value as appropriate.

  S65 is a notification step. The notification step S65 is executed when it is determined in the notification determination step S64 that the total amount of change information has exceeded the notification amount, and when the settlement machine 4 is turned on,

“The total amount of deposits was 6.5 million yen. Reference date as described in Article 4, Notification of Issuance of Self-issuing Prepaid Ceremony, etc., Chapter 2 of the Law on Regulations of Prepaid Ceremony, etc. If the total amount of deposits exceeds 7 million yen on March 31, the following matters must be notified to the Minister of Finance by the day when February passes from the next day. Do you control to lower the deposit from one week before March 31? Press “YES” or “NO: Notification” button to select.
1. Name, trade name or name and address, and in the case of a corporation, the name of the representative or administrator.
2. Type of voucher amount of self-issued prepaid voucher issued.
3. Base date unused balance on the base date. ]
This is a step of displaying the above sentence or informing by voice.

  S66 is an upper limit predetermined denomination setting change determination step. The upper limit predetermined denomination setting changing step S66 is executed in the notification determination step S64 when the total amount of change information is equal to or less than the notification amount or following the notification step S65. This is a step of comparing the total amount of change information calculated in the calculation step S63. In this embodiment, the change limit amount to be compared with the total amount of change information calculated in the total amount calculation step S63 in the upper limit predetermined denomination setting change step S66 is 7 million yen that causes a notification duty to the jurisdiction of the Ministry of Finance. The set value can be changed as appropriate.

  S67 is an upper limit predetermined denomination changing step for changing the upper limit predetermined denomination, and is executed when the total amount of change information is larger than the change limit in the upper limit predetermined denomination setting changing step S66. The upper limit predetermined denomination changing step S67 is a step of changing the currently set upper limit predetermined denomination to one smaller denomination. That is, the denomination initially set at 5,000 yen is changed to 2,000 yen. Thereby, since the upper limit predetermined denomination at the time of performing in predetermined denomination judgment step S19 and predetermined denomination setting step S20 is changed, the total amount of deposit can be made small. When the upper limit predetermined denomination changing step S67 is completed, the steps from the total amount calculating step S63 are repeated.

  S68 is an upper limit predetermined denomination return step, and is executed when the total amount of change information is equal to or less than the change limit in the upper limit predetermined denomination setting changing step S66. The upper limit predetermined denomination return step S68 is a step of comparing the total amount of change information calculated in the total amount calculation step S63 with the lower limit amount. The lower limit is the amount set for each upper limit denomination. For example, if the upper limit denomination is 2,000 yen, “If the upper limit denomination is 5,000 yen, It is a value that takes into account that it must not exceed 7 million yen ”,“ 7 million yen × 2,000 yen / 5,000 yen = 1.9 million yen multiplied by 0.7 with a margin of 2.8 million yen ” Is the amount of money.

  S69 is an upper limit denomination change step, and is executed following the upper limit predetermined denomination return step S68. The upper limit denomination changing step S69 is a step of changing the upper limit predetermined denomination to one denomination contrary to the upper limit predetermined denomination changing step S67. Therefore, the upper limit denomination change step S69 is provided together with the upper limit predetermined denomination return step S68, so that the total amount of change information calculated in the total amount calculation step S63 is less than or equal to the change limit amount and is closer to the change limit amount. It is possible.

  The steps of the total amount calculation step S63 to the upper limit denomination changing step S69 are changed at the time of comparison with the upper limit predetermined denomination performed in the predetermined denomination determination step S19 and the predetermined denomination setting step S20. The predetermined denomination determining step S19 and the predetermined denomination setting step S20 adopt the upper limit predetermined denomination changed in the calculation step S63 to the upper limit denomination changing step S69, so that the predetermined denomination for each customer is a deposit. It can be changed to the upper limit predetermined denomination controlled by the total amount of change information.

  The processing for monitoring the total amount of deposits recorded corresponding to the IDs in the total amount calculation step S63 to the upper limit denomination change step S69 is performed by a background job (BGJ) which is not a high priority interrupt processing. Or monitoring may be performed at predetermined intervals.

  In the change payment determination step S21, a predetermined customer denomination represented by a return number N [i] and a denomination (i) from a positive unsettled amount including 0 yen in which all the amounts have been settled, that is, a surplus amount (s). As a result of subtracting the product of the amount, if the predetermined denomination (for example, 1000 yen) is larger, the predetermined denomination return step S23 is executed. Otherwise, the return number adding step S22 is executed. When the change payment determination step 21 is executed for the first time, the return number N [i] is set to 0 according to the denomination amount setting step S18, that is, the denomination is 10,000 yen. The number of existing sheets is set to zero. Therefore, when the change payment determination step S21 is executed first, the return surplus addition step S22 is always executed for the positive surplus value (s) including 0 yen in which all the payments are settled.

  In the return number addition step S22, the return number N [i] of the denominations compared in the change payment determination step 21 is added by one, and the return number N [i] +1 is newly set as the return number N [i]. Step, and then the change payment determination step 21 is executed again.

  The predetermined denomination return step S23 is a step of returning the denomination (i) determined in the change payment determination step 21 by the return number N [i].

  The predetermined denomination determination step S24 for each customer is a step of determining whether or not the denomination processed in the change payment determination step S21, the return number addition step S22, and the predetermined denomination return step S23 is the predetermined denomination for each customer. If the denomination is not a predetermined denomination for each customer, that is, the processed denomination is a predetermined denomination greater than or equal to the amount permitted by the customer to record as change corresponding to the ID number of the change card CC. For example, the denomination changing step S25 is executed. Otherwise, the change card presence / absence determining step S26 is executed.

  In the denomination changing step S25, the denomination (i) set in the denomination amount setting step S18 is changed to the denomination (i + 1). And after denomination change step S25 execution, change payment judgment step S21 is performed again continuously. That is, in denomination changing step S25, denomination (i) set in denomination amount setting step S18 is denomination (0), that is, denomination is 10,000 yen, so denomination (i) is denomination (i + 1). That is, change to denomination 5,000 yen.

  Further, the denomination changing step S25 has a function of processing the next denomination by skipping the change-prohibited denomination preset for each customer card C. That is, for example, when a 500 yen coin is set as a change-prohibited denomination, after the processing of the 1000-yen denomination in each step of the change payment determination step S21 to the predetermined denomination determination step S24 for each customer, The change step S25 sets the denomination of the 100-yen coin, which is the next denomination of the 500-yen coin, to the denomination (i + 1) since the 500-yen coin as the next denomination is the change-prohibited denomination. In this way, it is possible to perform processing by skipping the denomination of 500 yen coins, and the predetermined change prohibited denomination is not processed in the change payment determination step S21 to the predetermined denomination determination step S24 for each customer. All 500 yen changes corresponding to the coin denomination will be returned in 100 yen coins. In addition, each time the denomination changing step S25 sets a new denomination by means of the card reader / writer 42, the change-inhibited denomination predetermined for each customer card C indicates whether or not the denomination is a change-prohibited denomination. The information recorded corresponding to C may be referred to, or when the information on the change prohibited type is recorded on the change card CC, change is already prohibited in the card insertion determination step S1. The denomination may be read and stored in the temporary storage area. Further, when a customer card C is newly issued, in the card issuing step S2, a change-prohibited denomination is provided and recorded in advance as information to be written to the new card or corresponding to the ID number of the new card.

  Accordingly, in the predetermined denomination determination step S24 and denomination change step S25 for each customer, the denomination (i) processed in the change payment determination step S21, the return number addition step S22, and the predetermined denomination return step S23 is determined for each customer. Until the predetermined denomination is reached, the change payment determination step S21, the return number adding step S22, and the predetermined denomination return step S23 are repeatedly executed.

  For example, when the predetermined denomination per customer is 1000 yen and the surplus price (change amount) calculated in the settlement price calculation step S172 is 4100 yen, first in the change payment determination step S21, the denomination (i) = 0, that is, denomination is set to 10,000 yen (set in denomination amount setting step S18), and N (0) is the number of sheets, so the comparison expression “s−10000 × 0” is smaller than the predetermined denomination “10000” Therefore, predetermined denomination return step S23 is performed continuously. However, since the number of sheets to be returned is 0, the 10,000 yen bill is not returned and the denomination changing step S25 is subsequently executed, and the denomination to be processed next is set to “5000”. And change payment judgment step S21 is performed again. Even in the processing of the denomination “5000”, the comparison formula “s-5000 × 0” is 4100, and “s-5000 × 0” is smaller than the denomination “5000”. The yen is not returned, and the predetermined denomination return step S23 to denomination change step S25 are executed. At this time, the denomination change step S25 sets the denomination to “1000” yen.

  Accordingly, in the change payment determination step S21 to be executed next, comparison with the denomination “1000” is performed, and subsequently, the change of the denomination (i) is set to 1000 yen in the denomination change step S25, and the change payment determination is performed again. Steps S21 to S23 are repeated.

  In the denomination of 1000 yen, the comparative expression “s−1000 × 0” is 4100, and 4100, which is “s−1000 × 0”, is larger than the denomination “1000”, so the change payment determination step S21 continues. The return number addition step S22 is executed, and the change payment determination step S21 and the return number addition step S22 are repeatedly executed until the number N [i] of the denomination 1000 yen becomes 4. When N [i] becomes 4, in the change payment determination step S21, the comparison formula is “s−1000 × 4”, that is, the calculation result is “4100−4000 = 100”, which is compared from the denomination “1000” being processed. Since the expression “s−1000 × 4” becomes smaller, the predetermined denomination return step S23 is subsequently executed. Therefore, in the predetermined denomination return step S23, since N [i] is 4, four 1000 yen bills are returned. Subsequent to the predetermined denomination return step S23, a predetermined denomination determination step S24 and a denomination change step S25 for each customer are executed again. Similarly, a new denomination is processed. However, for example, when the customer card C used is a change card CC and the lower limit of the predetermined denomination is 1000 yen, that is, up to 999 yen is recorded as change, the predetermined denomination determination step S24 for each customer Since the processed denomination is equal to or less than the amount permitted by the customer to be recorded as change corresponding to the ID number of the change card CC, the change card presence / absence determination step S26 is subsequently executed.

  Therefore, according to the change payment determination step S21, the return number addition step S22, the predetermined denomination return step S23, the predetermined denomination determination step S24 for each customer, and the denomination change step S25, the change amount to return each denomination. It is possible to return only the number of money corresponding to the amount.

  The change card determination step S26 is a step of determining whether or not the customer card C inserted into the card reader / writer 42 is a change card CC. If it is a change card CC, the change amount setting step S27 is subsequently executed. If it is not the change card CC, the change repayment step S29 is subsequently executed.

  The change amount setting step S27 is a step of setting, as the change amount (T), the remaining change that has already been returned in cash by the change payment determination step S21 to the denomination change step S25, followed by the premier point calculation step S28. Is done.

  The premier point calculation step S28 is a step of generating points corresponding to the total amount used by the customer, and the change card CC is used for the first rate for calculating the first point pt1 corresponding to the total amount. The second rate for calculating the premier point pt2, which is the second point to be granted, is added, the added rate is integrated with the total amount to calculate the point pt, the calculated point pt, A new point pt is calculated by adding the point pt that has already been recorded in correspondence with the ID number of the change card CC and replaced with the point pt. Therefore, the point pt added in the premier point calculation step S28 is a combination of the first point pt and the second point pt. When the change card CC is used, the premier point which is the second point is used. Will be added. Subsequent to the premier point calculation step S28, a change record determination step S31 is executed. In this embodiment, the total amount used when the points are calculated is the total amount purchased by the customer. However, the customer is recorded corresponding to the ID number of the customer card C in the point consumption desire determination step S11. If the user wishes to spend the points, the total amount after point consumption calculated in the point consumption step S12 may be used. Similarly, when the change stored corresponding to the ID number of the change card CC is consumed, the total amount obtained by subtracting the change amount to be further consumed may be used.

  The change repayment step S29 is a step to repay the entire change to be repaid and replace the change (T) with null, and the change inserted cannot be recorded because the card inserted in the card reader / writer 36 is not the change card CC. It is a step to return for. Following the change repayment step S29, a point calculation step S30 is executed.

  The point calculation step S30 is a step of calculating a point pt, and a point pt is calculated by integrating the first rate for calculating the first point pt1 corresponding to the total amount with the total amount, The point pt already recorded corresponding to the ID number of the point card CP is added to calculate a new point pt, which is replaced with the point pt. Subsequent to the point calculation step S30, a change record determination step S31 is executed.

  In this way, since the change card determination step S26 determines whether it is a change card CC, in the case of the change card CC, the change amount setting step S27 and the premier point calculation step S28 can calculate the premier points. If the inserted customer card C is a change card CC, it can be processed as a change card CC. Similarly, in the case of the point card CP, the change information to be stored corresponding to the ID number of the customer card C can be set as null by the change return step S29 and the point calculation step S30, and the first point can be calculated. If the inserted customer card C is a point card CP, it can be processed as a point card CP.

  The change record determination step S31 is a step of determining whether or not change is to be recorded corresponding to the ID number of the change card CC, and is determined according to the customer's request. In the change record determination step S31, when the change record button 48 of the settlement machine 4 is pressed and recording corresponding to the ID number of the change card CC is desired, the return of the change by the point card CP is completed. The surplus return confirmation step NN14 for determining whether or not there is a change is executed. If it is not desired, the change repayment step S34 is executed. If there is no answer, the additional write determination step S36 is executed. Here, if there is no answer, the change record determination step S31 to the record notification step S39 are repeated until it is determined that the card has been extracted in the card extraction confirmation step S40, and the customer waits while thinking. This is a step in which the description can be changed until the customer card C is removed. In the change record determination step S31, the customer makes the determination by pressing and instructing either the change return request button or the change record request button provided on the settlement machine 4, but the POS register 3 is operated. It may be configured such that a store clerk listens to a customer's wish and is instructed by pressing a predetermined key provided in the POS register 3 based on the wish. In the change record determination step S31, whether or not the customer wishes to record change corresponding to the ID number of the customer card C is determined by the change record button 48 or change return button 49 also received by the settlement machine 4. Judgment is made by pressing, but for example, only a button to be pressed when recording change is provided, and if the button is not pressed within a predetermined time, it is determined that the card is used as a point card CP. Then, the change repayment step S34 and the subsequent steps may be executed.

  As shown in FIG. 6 and FIG. 12, the surplus return confirmation step NN14 inquires about the change return history and determines whether there is a change return history, a change return history determination step NN140, and a predetermined denomination setting step NN141 for each customer. , Change change prohibition denomination setting step NN142, return display step NN143 for urging return of surplus change, and return determination step NN144 for determining whether or not surplus change has been received. The surplus return confirmation step NN14 determines that the change is recorded by the change record determination step S31 even though the change card determination step S26 determines that it is a point card CP and the change repayment step S29 returns the full amount of change. In other words, it is an effective means when it is desired to record a change in the change record determination step S31 in spite of the desire to use it as a point card CP in the change card determination step S26.

  The change return history determination step NN140 is a step of determining whether or not the full amount of change has been returned by the change repayment step S29. Specifically, the change return history is referred to by referring to the history information of the customer card C to be executed. In step S29, it is determined whether or not there is a change return history in which change less than the upper limit predetermined denomination is returned. When there is a change return history, a predetermined denomination setting step NN141 for each customer is subsequently executed, and when there is no change return history, a change amount setting step S32 is subsequently executed. In the change return history determination step NN140, the predetermined denomination for each customer of the point card CP is set as the upper limit predetermined denomination in the predetermined denomination setting step S20, so refer to the change return history of the set upper limit predetermined denomination. Thus, it is possible to determine whether or not the usage pattern before the determination by the change return history determination step NN140 is the use as the point card CP.

  The predetermined denomination setting step NN141 for each customer is executed following the change return history determination step NN140, sets the predetermined denomination for each customer desired in the point card CP to be processed, and is used as the point card CP. To use as a change card CC. In the predetermined denomination setting step NN141 for each customer, a default of 1000 yen is set when there is no desired denomination.

  The change prohibition denomination setting step NN142 is executed subsequent to the predetermined denomination setting step NN141 for each customer, and is a step of setting a change prohibition denomination. In the change prohibition denomination setting step NN142, it is not set when there is no desired denomination.

  The return display step NN143 is executed subsequent to the change-prohibited denomination setting step NN142, and among the changes already returned by the change-repayment step S29, changes less than the denomination set in the predetermined denomination setting step NN141 for each customer are displayed. It is a step of displaying on the display unit 45 of the checkout machine 4 so as to return it, and a step of prompting a return of change of less than a predetermined denomination for each customer.

  The return determination step NN144 is executed following the return display step NN143, and when there is a change less than the predetermined denomination per customer (when the return is completed), the change amount setting step S32 is executed. In other cases, the return display step NN143 is executed again. Accordingly, the return display step NN143 prompts the return of the change less than the predetermined denomination per customer by the return determination step NN144 until the change of less than the predetermined denomination per customer is returned. If the return amount determined to have been returned is greater than or equal to the predetermined denomination for each customer, the surplus is naturally returned to the customer.

Following the surplus return confirmation step NN14, a change amount setting step S32 is executed.
The change amount setting step S32 is a step of setting, as the change amount (T), the remaining change that has already been returned in cash by the change payment determination step S21 to the denomination change step S25, followed by the premier point calculation step S33. Is done.

  The premier point calculation step S33 is a step of generating points corresponding to the total amount used by the customer, and the change card CC is used for the first rate for calculating the first point pt1 corresponding to the total amount. The second rate for calculating the premier point pt2, which is the second point to be granted, is added, the added rate is integrated with the total amount to calculate the point pt, the calculated point pt, A point pt that has already been recorded corresponding to the ID number of the change card CC is added to calculate a new point pt, which is replaced with the point pt. Therefore, the point pt added in the premier point calculation step S28 is a combination of the first point pt and the second point pt. When the change card CC is used, the premier point which is the second point is used. Will be added. Subsequent to the premier point calculation step S28, an additional write determination step S36 is executed.

  The change repayment step S34 is a step to repay the entire change to be repaid and replace the change (T) with 0. Since the change of the change corresponding to the ID number of the change card CC is not desired, the change is returned. It is a step to do. Following the change repayment step S34, a point calculation step S35 is executed.

  The point calculation step S35 is a step of calculating the point pt, the point pt is calculated by integrating the first rate for calculating the first point pt1 corresponding to the total amount with the total amount, and the calculated point The point pt already recorded on the point card CP is added to calculate a new point pt, which is replaced with the point pt. Subsequent to the point calculation step S35, an additional write determination step S36 is executed.

  Thus, the change record determination step S31 is provided, and the change amount setting step S32, the premier point calculation step S33, the change repayment step S34, and the point calculation step S35 are provided, so that the customer uses the customer card C as the change card CC. It is possible to select whether the change is recorded in correspondence with the ID number of the card or whether the change is desired to be returned as the point card CP.

  Further, in addition to the change record determination step S31, the change amount setting step S32, and the premier point calculation step S33, the card withdrawal confirmation step S40 is provided so that the customer who has used the point card CP can pay the price. Even if you later decide to use the point card CP as a change card CC, you can choose to use it as a change card CC in the change record determination step S31 until it is determined that the card has been extracted in the card withdrawal confirmation step S40. As a change card CC, a predetermined change can be recorded in correspondence with the ID number of the card, and a premier point which is a score when using the change card CC can be recorded. Similarly, by providing a change record determination step S31, a change repayment step S34, a point calculation step S35, and a card withdrawal confirmation step S40, the customer who has used the change card CC can pay Even when reconsidering that the change card CC is to be used as the point card CP, until the card withdrawal confirmation step S40 determines that the card has been withdrawn, by selecting the use as the point card CP in the change record determination step S31, The change is returned in the change return step S34, and the first point can be recorded in the point calculation step S35.

  The additional recording determination step S36 is a step for determining whether or not to perform recording corresponding to the ID number of the change card CC, and the content to be recorded corresponding to the ID number of the customer card C is already recorded. In the case of the same, this is a step not to record again. Therefore, it is possible to avoid useless recording corresponding to the ID of the customer card C and useless description on the display unit C2 by the additional writing determination step S36. Subsequent to the postscript determination step S36, a recording step S37 is executed.

  In the recording step S37, the point pt set by the previous steps, the date and time of recording, the total amount purchased, the amount of cash paid, the gender as customer information, the age of appearance, the refund type for each customer, the refund for each customer This is a step of recording the refusal denomination. The content recorded in the recording step S37 is the content to be recorded regardless of the type of the customer card C, and is the change card CC even if the card inserted in the card reader / writer 36 is a point card CP. Is recorded in the magnetic recording unit C1 of the customer card C by the card reader / writer 36, and information set in advance in the display unit C2, for example, the recorded date and time (the customer can be recognized as the last use date). Display). Subsequent to the recording step S37, a change recording step S38 is executed. The items to be displayed on the display unit C2 of the customer card C can be appropriately selected and displayed according to the display capacity of the display unit C2 and the necessity of information to be displayed.

  Accordingly, when a new point pt obtained by adding the point pt generated by purchasing the point pt stored corresponding to the ID number of the customer card C receives the change using the point card CP in cash. Is calculated as the first point pt1 by the point calculation step S30, and when the change is recorded and used corresponding to the ID number of the change card CC using the change card CC, the premium point calculation step S28 It is calculated taking into account the premier point pt2, which is the second point, and is recorded corresponding to the ID number of the point card CP or the change card CC, respectively, in the recording step S37.

  In the change recording step S38, the change amount to be recorded calculated in the change amount setting step S27 is recorded in correspondence with the ID number of the change card CC, and the change amount recorded on the display unit C2, that is, the change amount that can be used next time. In this step, a certain change amount is displayed and described. In the change recording step S38, change can be recorded corresponding to the ID number of the change card CC in which the card reader / writer 36 is inserted only when the customer card C inserted in the card reader / writer 36 is the change card CC. It is.

  The recording notification step S39 is executed following the change recording step S38, and is a step for notifying that the recording corresponding to the ID number of the customer card C and the display on the display unit C2 are completed.

  The card withdrawal confirmation step S40 is executed following the recording notification step S39, and is a step of determining whether or not the customer card C has been removed from the card reader / writer 36. If it is determined in the card withdrawal confirmation step S40 that the customer card C has been withdrawn, the series of processing is terminated. If the customer card C has not been withdrawn, the process returns to the change record judgment step S31, and again the change record is recorded. Determination step S31 is executed. In this embodiment, the card withdrawal operation determined in the card withdrawal confirmation step S40 is an operation related to the completion of the settlement. In the card withdrawal confirmation step S40, the card removal is not confirmed but the POS register. The receipt of a signal notifying the completion of counting of all products to be settled according to 3 may be confirmed, and in addition to the receipt of the signal notifying the end of counting, the purchase button 46 is pressed and the payment is completed. May be confirmed, or it may be confirmed that a signal notifying the start of counting of the next customer's product is received from the POS register 3.

  Therefore, until the customer card C is withdrawn from the card reader / writer 36, the steps from the change record judgment step S31 to the card withdrawal confirmation step S40 are always repeated.

  The card insertion determination step S41 is executed when the payment determination step S5 determines that it is not a normal payment at the time of shopping but a change from the customer card C to the change card CC, etc. If there is no card inserted (ie, it is determined based on history information that the customer card C is not inserted first in the card insertion determining step S1), the input step S42 is executed, If there is an insertion, the elapsed time determination step S43 is subsequently executed.

  In the input step S42, since the point card CP was not inserted at the beginning, that is, it is not a change from the point card CP to the change card CC, but a new card needs to be issued. This is a step of manually inputting and obtaining the previous transaction total amount and the previous change amount from the receipt, and the elapsed time determination step S43 is subsequently executed.

  The elapsed time determination step S43 is a step of determining the elapsed time from the previous transaction, and the previous information reading step S44 is subsequently executed. In the elapsed time determination step S43, the previous information reading step S44 is executed if the predetermined period, for example, three months or a period that crosses the settlement date of the store has not passed since the previous transaction date. If the predetermined period has elapsed, the card confirmation process S is terminated.

  In the previous information reading step S44, since the previous transaction is within a predetermined period, the previous total amount, the previous change amount, and the recorded point pt, which are information when the previous transaction was made, are read. At this time, if there is no point card CP, the information is manually input in the input step S42.

  The point reading step S45 is executed following the previous information reading step S44, and reads the first point pt1 recorded corresponding to the ID number of the point card CP from the inserted point card CP. Replace as a point.

  The previous change amount replacing step S46 is executed following the point reading step S45, and the previous change information recorded corresponding to the ID number of the point card CP in the previous information reading step S44 or the input step S42. The input change information is set to be replaced with new change information, and then the denomination amount setting step S47 is executed.

  The denomination amount setting step S47 is the same as the denomination amount setting step S18. The upper limit predetermined denomination is set to 10,000 yen and 10,000 yen, 5,000 yen, 1,000 yen, 5 hundred yen, 1 hundred yen.・ Set each denomination (i) of 50 yen, 10 yen, 5 yen, and 1 yen to 0, and set the number of returned items N for each denomination (i) to 0. Step S48 is executed.

  The predetermined denomination determining step S48 is the same as the predetermined denomination determining step S19, and the upper limit predetermined denomination is compared with the predetermined denomination for each customer. If the predetermined denomination for each customer is larger than the upper limit predetermined denomination, the predetermined denomination is continued. The seed setting step S49 is executed, and in other cases, the change payment determination step S50 is executed.

  The predetermined denomination setting step S49 is the same as the predetermined denomination setting step S20. Since it is determined by the predetermined denomination determination step S48 that the predetermined denomination for each customer is larger than the upper limit predetermined denomination, the ID number of the change card CC is displayed. Correspondingly, the upper limit amount that can be recorded is set as the upper limit predetermined denomination, and then the change payment determination step S50 is executed.

  The change payment determination step S50 is the same as the change payment determination step S21. From the positive unsettled amount including 0 yen in which all the payments are settled, that is, from the surplus price (s), the number of returned sheets N [i] and the denomination As a result of subtracting the product of the customer predetermined denominations represented by (i), if the predetermined denomination (for example, 1000 yen) is larger, the predetermined denomination return step S52 is executed; S51 is executed. When the change payment determination step 50 is first executed, the return number N [i] is set to 0 according to the denomination amount setting step S47, that is, the denomination is 10,000 yen. The number of existing sheets is set to zero. Therefore, when the change payment determination step S50 is first executed, the positive surplus price (s) including 0 yen in which all the payments have been settled is always executed in the return number addition step S51.

The return number addition step S51 is the same as the return number addition step S22. The return number N [i] +1 is newly added by adding one return number N [i] of the denominations compared and determined in the change payment determination step 21. The step of setting the return number N [i] is followed by the change payment determination step 50 being executed again.
The predetermined denomination return step S52 is the same as the predetermined denomination return step S23, and is a step of returning the denomination (i) determined in the change payment determination step 50 by the return number N [i].

  The predetermined denomination determination step S54 for each customer is the same as the predetermined denomination determination step S24 for each customer, and the denominations processed in the change payment determination step S50, the return number addition step S51, and the predetermined denomination return step S52 are: It is a step for determining whether or not the denomination is a predetermined denomination for each customer, and if the denomination is not for each customer, that is, the processed denomination may be recorded as change corresponding to the ID number of the change card CC by the customer. If the predetermined denomination is equal to or greater than the permitted amount, the denomination changing step S55 is executed, otherwise the change amount setting step S56 is executed.

  The denomination changing step S55 is the same as the denomination changing step S25, and the denomination (i) set in the denomination amount setting step S47 is changed to the denomination (i + 1). And after denomination change step S55 execution, change payment judgment step S50 is performed again continuously. That is, in denomination changing step S55, denomination (i) set in denomination amount setting step S47 is denomination (0), that is, denomination is 10,000 yen, so denomination (i) is denomination (i + 1). In other words, the money type is changed to 5,000 yen.

  Therefore, in the predetermined denomination determination step S54 and denomination change step S55 for each customer, the change payment determination step S50 to the predetermined denomination return step S52 are processed in the same manner as the change payment determination step S21 to the predetermined denomination return step S23 described above. Since the change payment determination step S50 to the predetermined denomination return step S52 are repeatedly executed until the denomination (i) to be made becomes a predetermined denomination for each customer, according to the change payment determination step S50 to the denomination change step S55, It is possible to return only the number of money corresponding to the amount of change to return each denomination. Here, in the change payment determination step S50 to the denomination change step S55, processing is performed based on the previous information. Therefore, when a new customer card C is issued, it is performed when there is no previous customer card C. Points will be awarded retroactively.

  The change amount setting step S56 is a step of setting, as the change amount (T), the remaining change that has already been returned as cash as the previous information by the change payment determination step S50 to the denomination change step S55, and subsequently the display step S57. Is executed.

  The display step S57 is a step for causing the price display unit 33 to display the change amount (T) paid out last time. Accordingly, the price display unit 33 can display the amount calculated in the change amount setting step S56, and when executed after the change return determination step S59, the amount received in the change return reception step S58 is subtracted. The shortage amount, which is a change amount, can be displayed.

  The change return acceptance step S58 is executed after the display step S57 is completed, and is a step for accepting the customer paying the previous change amount (T), and the paid amount is newly issued. Alternatively, the amount is stored as change information from the point card CP to the changed change card CC. Further, in the change return acceptance step S58, the shortage amount can be calculated by subtracting the accepted amount from the previous change (T).

  The change change determination step S59 is executed following the change return reception step S58, and monitors whether or not the received amount has reached the previous change amount (T). Subsequently, change change step S60 is executed, and if not reached, display step S57 is executed again.

  Accordingly, the display step S57 to the change return determination step S59 can always wait for payment from the customer until the previous change amount (T) is paid, and when the amount has been reached, the next step can be executed. . The change return acceptance step S58 is completed when the store clerk receives an amount corresponding to the previous change amount (T) from the customer, and subsequently presses a predetermined button (not shown) to change the change return determination step S59. When the process is completed and the store clerk does not press a predetermined button (not shown), the display step S57 to the change return determination step S59 may be repeated.

  In the change change step S60, the previous change amount (T) paid by the customer is stored in correspondence with the ID number of the change card CC. This is a step of temporarily replacing and storing. Following the change replacement step S60, a premier point calculation step S61 is executed.

  The premier point calculating step S61 is a step for generating points corresponding to the total amount used by the customer, and for calculating a premier point pt2 which is a second point given for using the change card CC. The point pt is calculated by multiplying the second rate by the previous total amount, and the calculated point pt is added to the point pt that has already been recorded corresponding to the ID number of the customer card C to obtain a new point pt. Is calculated and replaced with the point pt. Therefore, the point pt added in the premier point calculation step S61 corresponds to the ID number of the change card CC using the change card CC because the first point pt1 has already occurred at the previous shopping. The first point pt1 and the second point when the change card CC is used are calculated by calculating only the premier point pt2, which is the second point generated by recording, and adding it to the point pt generated so far. This means that the premier point pt2, which is a point of the above, is added. Following the premier point calculation step S61, a point recording step S62 is executed.

  In the point recording step S62, the new point pt calculated in the premier point calculating step S61 is recorded in correspondence with the ID number of the change card CC, and the recorded point pt is displayed on the display unit C2. Of course, when there is no need to record the point pt on the display unit C2 and show it to the customer, it is not necessary to display the point pt on the display unit C2, and it can be set according to the use environment such as a store.

When the point recording step S62 is completed, a change recording step S38 is subsequently executed.
Therefore, the card insertion determination step S41 to the point recording step S62 are steps performed when the customer changes the point card CP that has been used so far to the change card CC.

  In the above description, the customer card C that is an old point card is abolished and a new point card CP or change card CC is issued, but the customer card C that is an old point card is abolished. It is also conceivable to form it so that it can be used together with a customer card C that is newly issued without any problems.

  Therefore, the case where the customer card C, which is an old point card, and the customer card C, which is a newly issued point card CP or change card CC, can be used will be described below.

  In this case, since there are two types of customer cards C that can be used, an old customer card C and a new customer card C, each customer card C must be read and written by different reader / writers. Among the above steps, point reading step S10, point consumption step S12, premier point calculating step S28, point calculating step S30, premier point calculating step S33, point calculating step S35, recording step S37, point reading step S45, premier point calculating step By adding the following functions to the functions of S61 and point recording step S62, two types of old customer card C and new customer card C can be used.

  That is, when the customer card C, which is an old point card, is used, a card reader / writer that can read from and write to the customer card C, which is an old point card CP, is separately provided. When a customer card C, which is an old point card, is used, reading / writing is performed by this card reader / writer. When a customer card C, which is a newly issued point card CP and change card CC, is used, the card Reading / writing is performed by the reader / writer 36.

  In the point reading step S10, when the point information read based on the ID number of the customer card C is replaced with usable point information that can be used for payment, the customer card C to be used is inserted. The ID number is received from the card reader / writer, and the point information is read.

  In the point consumption step S12, when the points to be updated and recorded corresponding to the ID number of the customer card C are replaced with 0 as a result of consuming the points, the ID number of the customer card C being used corresponds. To record.

  In the premier point calculating step S28 and the premier point calculating step S33, the customer card C used by the customer when this step is executed is a change card CC, so that it is processed by the card reader / writer 36 of the new customer card C. To do.

  In the point reading step S45, when the first point pt1 recorded corresponding to the ID number of the point card CP is read from the inserted point card CP, the point card CP used is an old customer card. If it is C, the ID number is read from the card reader / writer for the customer card C, which is an old point card. If the point card CP is a new customer card C, the card reader / writer for the new customer card C is read. The ID number is read from 36. Of course, in both the new and old cards, when points and changes are recorded on the card, it is only necessary to write directly from the card reader / writer because the card is already supported.

  Also in the premier point calculation step S61, when the point card CP used at the previous time is the old customer card C, the customer card C whose first point pt1 already generated at the previous shopping is the old point card is used. Therefore, the ID number is read from the card reader / writer 36 for the customer card C, which is an old point card. Of course, if the point card CP at the time of the new last use is the new customer card C, it is read as it is from the card reader / writer 36 for the new customer card C.

  In the point recording step S62, the new point pt calculated in the premier point calculating step S61 is recorded corresponding to the ID number of the change card CC, and the recorded point pt is displayed on the display unit C2. In this case, if the customer card C to be written is an old one, the card reader / writer 36 for the old customer card C is used. If the customer card C is a new one, the card reader / writer for the new customer card C is used. 36, information is written respectively. When the old customer card C is a card that does not have the display unit 2, the card reader / writer 36 for the old customer card C does not have to have a display function on the display unit 2.

  Then, for the customer card C, which is an old point card, in the point calculation step S30 and the point calculation step S35, the calculated point pt is already recorded in correspondence with the ID number of the point card CP. When adding, if the point card CP being used is an old customer card C, the ID number is read from the card reader / writer 36 for the old customer card C and recorded corresponding to this ID number. Form to read point pt.

  Further, when the point card CP being used is an old one when recording on the card in the recording step S37, a new customer card C is created by the card reader / writer 36 for the old customer card C. In this case, the card reader / writer 36 for a new customer card C is formed so as to record corresponding to the ID number of the corresponding customer card C.

By doing in this way, it becomes possible to additionally introduce a change card CC to be newly issued to a conventional point card introduction store and a point card CP to be newly issued, and the introduction equipment is not wasted. In addition, two types of card readers / writers exist here, but one type of card reader / writer includes a customer card C that is an old point card, a newly issued change card CC, and a newly issued point card CP. You may make it read-write. This is preferable because it is not necessary to waste the customer card C, which is an old point card.
And it forms so that use frequency determination step S3 may be performed continuously.

  The operation of the present invention will be described below. In the following description, the customer card C is inserted by a customer into a card reader / writer 42 provided in the checkout machine 4, cash paid by the customer and change to be returned to the customer are also performed by the checkout machine 4, and the POS register 3 is The purchase settlement price purchased shall be calculated. The predetermined denomination for each customer that determines the amount that can be recorded corresponding to the ID number of the change card CC is 1000 yen, and 999 yen is the upper limit of the amount that can be recorded corresponding to the ID number of the change card CC. The upper limit predetermined denomination is set in advance to 5,000 yen. Further, the card inserted into the card reader / writer 42 to be used is a change card CC whose use count is before the use limit and change information indicating the change amount that can be used is 300 yen. Furthermore, it is assumed that the record corresponding to the ID number of the change card CC is 100 points with point information equivalent to 100 yen. Furthermore, the first rate for calculating the first point pt1 is 3%, and the second rate for calculating the second point, the premium point pt2, is 5%.

When the customer purchases and pays for the product, the customer brings the product to the POS register 3.
When the customer uses the customer card C for payment, the customer card C is inserted into the card reader / writer 42. Then, it is determined that a card has been inserted in the card insertion determination step S1, and subsequently the use count determination step S3 is executed. In the card insertion determining step S1, there is a predetermined button (not shown) provided on the checkout machine 4 that is pressed when a card is inserted or the customer does not want to pay by card (the customer does not have the customer card C). Judgment is made when pressed, and waits until either action occurs.

In the POS register 3, the store clerk operates the bar code reader unit 34, the handy reader unit 35, and the key operation unit 31 of the POS register 3 to cause the POS register 3 to calculate the total amount. At this time, the control unit 37 controls the POS register 3 as a whole, and controls the reading of the product name and price by the barcode reader unit 34 and the like, and the price display unit 33 inputs the price of each product. Each time the product is recorded, the name and price of the product recorded by the barcode or the like are displayed, and the total amount of the product so far is displayed. At the same time, these pieces of information or information of only the price is output to the settlement machine 4. At this time, the information output to the settlement machine 4 may be set as appropriate so that only the set information is output. Also in the checkout machine 4, these pieces of information are input and the control unit 43 controls the display unit 45 to display the same information as the price display unit 33 of the POS register 3. Hereinafter, in the description of this embodiment, it is assumed that the total amount of products purchased by the customer is 4100 yen.
When the input of all purchased products is completed, the POS register 3 calculates the total price of the products. The POS register 3 outputs the total amount purchased by the customer to the checkout machine 4.

  On the other hand, the settlement machine 4 executes the point and change information recording process F, and when the point card CP or the change card CC is inserted into the card reader / writer 42 before the total amount is input from the POS register 3. The card insertion determination step S1 determines that a card has been inserted, and subsequently the use count determination step S3 is executed. If no point card CP or change card CC is inserted into the card reader / writer 42, the card issuing step S2 is executed. In this embodiment, the case where the customer inserts the change card CC into the card reader / writer 42 will be described. However, in the card issuing step S2 performed when the customer card C is not inserted, the customer's year of birth is not described in detail. Data related to customers such as date and phone number, data such as IDs for identifying cards, amount and date of purchase of a product, change amount in pool card and date when change occurred, customer Necessary data such as predetermined denominations are recorded on the card ID number in the magnetic recording unit C1, and other information is recorded in the history storage unit 47 and issued. When recording in the history recording unit 47, recording is performed corresponding to the ID number of the customer card C. Information that does not cause major damage when the card is used, such as the card usage limit, may be recorded in the magnetic recording unit C1 of the customer card C, and can be set as appropriate. In the new issuance in the card issuance step S2, information that has not been generated such as a change amount is set to 0 or null. Further, a temporary customer card C may be issued, and a customer card C which is a regular point card CP, change card CC or change card CC may be issued again at another department such as a service counter. .

  Since the change card CC is inserted into the card reader / writer 42 by the customer, the use count determination step S3 is executed following the card insertion determination step S1, and the change card CC of the inserted change card CC read by the card reader / writer 42 is executed. If the usage count is equal to or greater than the usage limit, the inserted customer card C is collected in the card reader / writer 42, and a new change card is issued in the card issuing step S2. Issue CC. The change card CC issued at that time is issued so as to have the same data as the original change card CC except for the number of times of use. Cards that have reached the limit of use may be collected by providing a card stacker to be stocked in the card reader / writer 42 or an apparatus to which the card reader / writer 42 is attached and collecting it in the card stacker. Also, a card insertion / extraction port for the card reader / writer 42 is provided on the customer side, and a card discharge port is provided on the cashier side as a store clerk. When the customer card C reaches the use limit and is collected, the card may be discharged from the card outlet provided on the cashier side and collected by the cashier. The same applies when the inserted customer card C is a point card CP.

  Since the inserted change card CC is used less than the use limit, it is determined that the change card CC is less than the use limit. Subsequently, the use count adding step S4 is executed, and the card reader / writer 42 is incremented once and used again. Overwrites the change card CC. Of course, the same applies when the inserted card is a point card CP.

  Subsequently, settlement determination step S5 is executed. In this embodiment, since the payment is made when the change card CC is purchased, it is determined to be a normal settlement, and subsequently the change information determination step S7 is executed. Note that the card inserted into the card reader / writer 42 is a point card CP, and when the card type is changed from the point card CP to the change card CC, it is determined that the payment is not a normal settlement, and the card insertion determination step S41 continues. Executed. The judgment performed in the settlement judgment step S5 is performed by selecting whether the customer is a regular settlement or a card type change by using a selection button (not shown) or the like. 3 may be configured to press a predetermined key (not shown) and make a determination based on the pressed key. Processing when branching to the card insertion determination step S41 will be described later.

  Next, change information determination step S7 is executed, and it is determined whether or not change information is stored corresponding to the ID number of the customer card C. In the change information determination step S7, since the card inserted in the card reader / writer 42 is the change card CC, it is determined that there is change information, and the change information reading step S9 is subsequently executed. If the card inserted in the card reader / writer 42 is a point card CP, there is no change information, and therefore, change information replacement step S8 is executed. In change information replacement step S8, change information is changed to the change amount 0. It is generated and replaced as a yen, and the processing is continued assuming that the change information is pseudo 0 yen (the point reading step S10 is subsequently executed).

  Next, in the change information reading step S9, usable change information of 300 yen is read from the change card CC inserted into the card reader / writer 42.

  Subsequently, the point reading step S10 is executed, and the point information pt, which is 100 points, is read from the ID number of the change card CC inserted into the card reader / writer 42. The read points can be used as a part of the settlement fee.

  Subsequently, the point consumption desire determination step S11 is executed. In point consumption desire determination step S11, it is determined whether or not the customer wants to use points. In this embodiment, when the cashier presses a predetermined key of the POS register 3, the pressed information is held, and it is determined that point consumption is desired in the point consumption request determination step S11. Here, since it is assumed that the point consumption is desired, the point consumption step S12 is subsequently executed. If the point consumption is not desired, the settlement price display step S16 is executed.

  Since it is determined that point consumption is desired in step S11, the point consumption step S12 is executed, and the point pt read in the point reading step S10 is 100 points, that is, 100 yen as a part of the payment price. Since the point is used and the point is consumed, the point to be updated and recorded as the information of the customer card C is replaced with 0. In the point consumption step S12, when the usable point information replaced in the point reading step S10 is larger than the total price, the remaining points after the total price deduction are updated and recorded as information on the customer card C. The calculated new total price is 0. Further, when the points consumed in the point consumption step S12 are formed to be processed as the amount equivalent to the customer's offer amount, the store clerk or the customer operates the use point setting button (not shown), for example, the total Only the fractional part of the amount will be allocated with points.

  Next, in the settlement price display step S16, the unsettled amount (s) 3700 yen is displayed on the price display section 33 and the display section 45. Therefore, the price display unit 33 and the display unit 45 display the amount calculated in the settlement price display step S16 and make the customer and the cashier recognize.

  Subsequently, the deposit acceptance step S17 is executed, and the payment of the price displayed in the settlement price display step S16 is awaited. In the embodiment in which the settlement is performed only with the POS register 3 without providing the settlement machine 4, the cashier waits until the cashier receives cash equivalent to the settlement price or more from the customer and presses the predetermined key. .

  That is, first, a deposit acceptance step S171 is executed, waiting for a customer to directly insert cash into the cash underwriting unit 41, and when it is inserted, the amount of the inserted bill or coin is recognized as the deposit amount. Subsequently, the settlement price calculation step S172 is executed.

  In the settlement price calculation step S172, the amount deposited in the deposit acceptance step S171 and the point amount calculated in the point consumption step S12 are subtracted from the total price, and an unsettled amount (surplus) s as a new settlement price to be settled. Is calculated. That is, in the settlement price calculation step S172, the unsettled amount (s) calculated in consideration of the payment price allocation and the total price based on the change information read in the point and change information reading step S9 in the point consumption step S12, Subtraction from the amount received in the deposit acceptance step S171, an unsettled amount (s) is calculated as a new settlement amount to be settled, and then a payment end determination step S173 is executed. It should be noted that the unsettled amount (s), which is the new settlement price to be settled, calculated in the settlement price calculation step S172 may be temporarily stored instead of being updated and stored. You may do it. Further, in this embodiment, the settlement with the change card CC is described, but the same applies to the case with the point card CP.

  Next, the payment completion determination step S173 is executed, and it is determined whether or not there is a new payment price to be settled calculated in the settlement price calculation step S172, and there is an unsettled amount (s) (the settlement price is 0). Therefore, the settlement price display step S16 is executed again to display the unsettled price amount.

  When the customer inserts a 5,000-yen bill into the cash acceptance unit 41 of the settlement machine 4, the 5,000-yen bill is accepted in the deposit acceptance step S171, and the 5,000-yen accepted in the settlement amount calculation step S172 is subtracted from 5,000 yen. Then, +1300, which is an unsettled amount (s), is calculated as a new settlement price to be settled. Since the new unsettled amount (s) is +1300, since the new unsettled amount (s) is positive in the subsequent payment end determination step S173, the money type amount setting step S18 is executed. The When the customer inserts four thousand yen bills, for example, when the customer inserts the thousand yen bill into the cash acceptance unit 41 of the settlement machine 4, the deposit acceptance step S171 accepts the thousand yen bill and calculates the settlement price step S172. Subtracts 1000 yen received in the deposit acceptance step S171 to calculate -2700, which is an unsettled amount (s), as a new settlement price to be settled. Subsequently, since the newly calculated unsettled amount (s) is 0 or less, that is, still exists in the payment end determination step S173, the settlement amount display step S16 is executed again to cause the display unit 45 to newly display the new unsettled amount (s ) Is 2700 yen.

  The customer sequentially inserts cash into the cash underwriting unit 41 while confirming the amounts sequentially displayed in the settlement price display step S16. In this embodiment, it is assumed that four thousand yen bills have been inserted. Therefore, when the customer inserts four thousand yen bills by repeating the steps from the settlement price display step S16 to the payment end determination step S173, the settlement price calculation is performed. In step S172, the new unsettled amount (s) is +300. Then, since the new unsettled amount (s) becomes positive in the payment end determination step S173 to be executed subsequently, the money type amount setting step S18 is executed subsequently. Before executing the denomination amount setting step S18, a step equivalent to the settlement price display step S16 is provided again, and the price already paid exceeds the purchase price. That is, the purchase price (the price to be paid) You may display 3700 yen and the paid amount of 4000 yen. By providing the display step in this way, the customer can visually confirm how much change is made. If the unsettled price (s) calculated in the settlement price calculation step S172 is temporarily stored separately, the settlement price display step S16 always displays the latest unsettled price (s) on the display unit 45. Display.

  In the subsequent denomination amount setting step S18, the predetermined denomination is set to 10,000 yen and 10,000 yen, 5,000 yen, 1,000 yen, 5 hundred yen, 1 hundred yen, 50 yen, 10 yen. Set each denomination (i) of 5 yen and 1 yen to 0, that is, 10,000 yen, and set the return number N for each denomination (i) to 0. The denomination (i) set at this time is i = 0 represents 10,000 yen, i = 1 represents 5,000 yen, i = 2 represents 1,000 yen, and i = 3 represents 500 yen. I = 4 represents 1 hundred yen, i = 5 represents 50 yen, i = 6 represents 10 yen, i = 7 represents 5 yen, and i = 8 represents 1 yen. N represents the number of sheets, and is represented by a natural number such as N = 0, 1, 2, 3, 4,. Accordingly, the return number N [i] represents, for example, that the return number 3 [2] when i = 2 and N = 3 is three thousand yen, that is, 3000 yen. The predetermined denomination represents how much the amount of change desired to be recorded and returned corresponding to the ID number of the change card CC when the customer receives the change. If it is 1000 yen, the change of less than 1000 yen, that is, up to 999 yen is recorded as change information corresponding to the ID number of the change card CC.

  Next, in the predetermined denomination determination step S19, the upper limit predetermined denomination is compared with the predetermined denomination for each customer, and if the predetermined denomination for each customer is larger than the upper limit predetermined denomination, the predetermined denomination setting step S20 is executed. In other cases, the change payment determination step S21 is executed. Since the predetermined denomination per customer is 1000 yen and the upper limit predetermined denomination is 5000 yen, the change payment determination step S21 is subsequently executed. When the upper limit predetermined denomination is, for example, 500 yen, the predetermined denomination setting step S20 is subsequently executed. Although not executed in this embodiment, the case where the upper limit predetermined denomination is 500 yen will be described below. In the predetermined denomination setting step S20, the predetermined denomination for each customer recorded corresponding to the ID number of the change card CC is set as the upper limit predetermined denomination. Therefore, the predetermined denomination for each customer is treated as 500 yen which is the upper limit predetermined denomination while the point and change information recording process F is being executed. And, by replacing the predetermined denomination per customer with the upper limit predetermined denomination in this way, when the total amount of change card CC deposit that is a duty to report deposit to the treasury department on the store side exceeds 7 million yen For example, by changing the denomination of the upper limit predetermined denomination to a predetermined denomination, the change amount to be returned in cash is increased, and the amount of change information to be recorded corresponding to the ID number of the change card CC is reduced. It is possible to adjust the total deposit amount to 7 million yen or less.

  Subsequently, a change payment determination step S21 is executed. In the change payment determination step S21, the product of the number of returned money N [i] and the customer's predetermined denomination represented by denomination (i) from 1300 yen which is a positive unsettled amount (s) (surplus price) including 0 yen is calculated. The subtracted comparison formula “s−predetermined denomination × N [i]” is compared with the amount of the predetermined denomination. In other words, 1300 which is a comparison expression “1300−10000 × 0” obtained by subtracting 0 which is the number of returned sheets N = 0 and denomination (i) = 10000 from surplus money (s) = 1300 and the predetermined denomination “10000 yen” As a result of comparison with 10000, the comparison formula “1300−10000 × 0” is smaller than the predetermined denomination amount 10000, and therefore the predetermined denomination return step S23 is executed. In the predetermined denomination return step S23, the predetermined denomination is not returned to the customer because the number of returned predetermined denominations is zero.

  After the predetermined denomination return step S23, a predetermined denomination determination step S24 for each customer is executed, and the denomination (i) = 10,000 yen processed in the change payment determination step S21 to the predetermined denomination return step S23 is predetermined for each customer. As a result of determining whether or not it is a denomination, the denomination changing step S25 is executed because it is not 1000 yen which is a predetermined denomination for each customer.

  In the denomination changing step S25, the denomination (i) = 10000 currently being processed is changed to the denomination (i) = 5000 which is the next denomination, and then the change payment determination step S21 is executed again.

  In the change payment determination step S21, the denomination (i) has been changed to 5,000 yen, so the number of returned items N = 0 when the denomination (i) set in the denomination amount setting step S18 is 5,000 yen. Since the denomination (i) = 5000 is 0, the return number N = 0, and the denomination (i) = 5000 is subtracted from the surplus price (s) = 1300 by the comparison expression “1300−5000 × 0”. As a result of comparing a certain 1300 with 5000 of the predetermined denomination “5000 yen”, the comparison expression “1300-10000 × 0” is smaller than the predetermined denomination amount 5000, and therefore the predetermined denomination return step S23 is executed. Is done.

  In the predetermined denomination return step S23, since the number of sheets to be returned for the predetermined denomination “5000 yen” is 0, it is not returned to the customer.

  Following the predetermined denomination return step S23, the predetermined denomination determination step S24 for each customer is executed again, and the denomination (i) = 5,000 yen processed in the change payment determination step S21 to the predetermined denomination return step S23 is determined for each customer. As a result of determining whether or not the denomination is the predetermined denomination, the denomination changing step S25 is executed because the predetermined denomination for each customer is not 1000 yen.

  In the denomination changing step S25, the denomination (i) = 5000 currently processed is set to the denomination (i) = 1000 which is the next denomination, and the change payment determination step S21 is subsequently executed again. If the denomination to be newly set in the denomination changing step S25 corresponds to the change-prohibited denomination, the denomination changing step S25 skips the denomination and sets the next denomination.

  In the change payment determination step S21, since the denomination (i) is changed to 1,000 yen, the return number N = 0 when the denomination (i) set in the denomination amount setting step S18 is 1,000 yen, the money By comparing 0 with seed (i) = 1000, 1300 which is the comparison formula “1300−1000 × 0” is compared with 1000 which is the amount of the predetermined denomination. As a result of the comparison, 1300, which is the comparison expression “1300-1000 × 0”, is larger than 1000, which is the amount of the predetermined denomination, so the return number adding step S22 is subsequently executed.

  In the return number addition step S22, the return number N is incremented by one to set the return number N = 1, and then the change payment determination step S21 is executed again.

  In the change payment determination step S21, as in the case where the number of predetermined denominations N = 0, the return number N = 1, the same denomination (i) = 1000, and the surplus price (s) = 1300, so the comparison formula “1300−1000 × 1 "300" and 1000 which is the amount of the predetermined denomination are compared again. As a result of comparison, 300, which is the comparison expression “1300−1000 × 1”, is smaller than 1000, and therefore, the predetermined denomination return step S23 is executed.

In the predetermined denomination return step S23, the currently processed return number N = 1 denomination (i) = 1,000 yen is returned from the change payment unit 44 to the customer.
Therefore, the customer has received a return of 1000 yen so far, and the remaining amount is 300 yen.

  Next, the predetermined denomination determination step S24 for each customer is executed again, and it is determined whether or not the denomination (i) = 1,000 yen processed in the change payment determination step S21 to the predetermined denomination return step S23 is the predetermined denomination for each customer. As a result, since the predetermined denomination per customer is 1000 yen, the change card determination step S26 is subsequently executed.

  In the change card determination step S26, it is determined whether or not the customer card C inserted in the card reader / writer 36 is a change card CC, and since it is a change card CC, a change amount setting step S27 is subsequently executed. If the inserted customer card C is not the change card CC, the change repayment step S29 is subsequently executed.

  Since the determination in the change card determination step S26 is the change card CC, a change amount setting step S27 is executed following the change card determination step S26. The change amount setting step S27 is a step of setting, as the change amount (T), the remaining 300 yen of the change that has already been returned in cash by the change payment determination step S21 to the denomination change step S25. Step S28 is executed.

  In the premier point calculation step S28, since the total amount used by the customer was 4100 yen, this is a step of generating points corresponding to 4100 yen, in order to calculate the first point pt1 corresponding to the total amount 4100 yen. 5%, which is the second rate for calculating the premier point pt2, which is the second point to be granted for using the change card CC, is added to 3%, the first rate of The point pt = 328 is calculated by accumulating the rate 8% with the total amount of 4100 yen, and the calculated point pt = 328 is added to the point pt = 100 already recorded corresponding to the ID number of the change card CC. Then, a new point pt = 428 is calculated and replaced with the point pt. Accordingly, the point pt = 428 added in the premier point calculation step S28 is a combination of the first point pt and the second point pt (equivalent to first rate × total amount + second rate × total amount). Thus, when the change card CC is used, the premier point as the second point is added. Subsequent to the premier point calculation step S28, a change record determination step S31 is executed. In this embodiment, the total amount used when calculating the points is set to 4100 yen, which is the total amount of the purchase by the customer. However, the customer corresponds to the ID number of the customer card C in the point consumption desire determination step S11. If the user wishes to consume the recorded points, the total amount after the point consumption calculated in the point consumption step S12 may be 4000 yen. Similarly, it corresponds to the ID number of the change card CC. When 300 yen, which is the change stored, is consumed, it may be 3700 yen, which is a total amount obtained by subtracting points that further consume 300 yen, which is the change amount.

  Subsequent to the premier point calculation step S28, a change record determination step S31 is executed.

  However, there is a case where the change card determination step S26 branches to the change repayment step S29. Here, the case where the change card determination step S26 determines that the customer card C is not the change card CC will be described. In this case, a change repayment step S29 is executed following the change card determination step S26. In the change repayment step S29, 300 yen which is the total amount of change to be repaid is repaid and the change amount (T) to be recorded corresponding to the ID number of the change card CC is replaced with null. Following the change repayment step S29, a point calculation step S30 is executed.

  In the point calculation step S30, 3% which is the first rate for calculating the first point pt1 corresponding to the total amount of 4100 yen is integrated with the total amount of 4100 yen to calculate the point pt = 123. The added point and the point pt = 100 already recorded corresponding to the ID number of the point card CP are added to calculate a new point pt = 223, which is replaced with the point pt. Therefore, when the point card CP is used, the premium point pt2 as the second point is not taken into consideration. Following the point calculation step S30, the change record determination step S31 is executed in the same manner as the premier point calculation step S28. The above shows the executed state when the point card CP is used.

In the change record determination step S31, it is determined whether or not the customer wishes to record change corresponding to the ID number of the change card CC. The customer card C inserted in the card reader / writer 42 is the point card CP. If the customer presses a cash return button (not shown) provided on the checkout machine 4 himself / herself, it is determined that the change is desired to be returned in cash, and the change repayment step S34 is executed, and the card reader / writer 42 is also executed. The customer card C inserted in the change card CC is a change card CC, and the customer desires a change record corresponding to the ID number of the change card CC. When not pressed, it is determined that the change is recorded corresponding to the ID number of the change card CC, and the surplus return confirmation step NN14 is executed. Only change amount setting step S32 and is executed, recordable determination step S36 are continuously executed. Therefore, in this description, the customer has pressed a change record request button (not shown) installed on the settlement machine 4 in order to change the record corresponding to the ID number of the change card CC. Subsequently, the surplus return confirmation step NN14 and the change amount setting step S32 are executed. In addition, when a customer wants to receive change with cash, the cash return button (not shown) provided in the checkout machine 4 is pressed. Then, the change repayment step S34 and the point calculation step S35 are executed continuously, the change is returned in cash, and the points generated for the purchase amount are only the first point.
If no change record request button (not shown) or cash return button (not shown) is pressed, an additional answer determination step S36 is automatically executed in succession. In this case, since it is determined that there is no additional article in the additional recording determination step S36, the card withdrawal confirmation step S40 is continuously executed, and the change record determination step S31 is continuously executed until the card is extracted. The process is repeated until a change record request button (not shown) or a cash return button (not shown) is pressed or the customer card C is pulled out. Therefore, the usage pattern of the customer card C can be changed by this repeated loop until the customer card C is removed.

Subsequently, a surplus return confirmation step NN14 is executed. In the surplus return confirmation step NN14, a change return history determination step NN140 is first executed. In the change return history determination step NN140, the currently used customer card C is the change card CC, and the change amount has not been returned in the change repayment step S29, so the change amount setting step S32 is subsequently executed.
Note that the customer card C currently in use is a point card CP, the change has been fully returned in the change repayment step S29, and the customer wishes to record the change corresponding to the ID number of the customer card C. In other words, when the customer card C is changed from the use as the point card CP to the use as the change card CC, the change return history in which change less than the upper limit predetermined denomination is returned in the change repayment step S29 is recorded. Therefore, in the change return history determination step NN140, the predetermined denomination setting step NN141 for each customer is executed, and the predetermined denomination for each customer when the customer card C is used as the change card CC is key-operated by the customer. Set by being input by. Next, a change prohibited money type setting step NN142 is executed, and a prohibited money type for each customer is set in the same manner as the predetermined money type setting step NN141 for each customer. Next, the return display step NN143 is executed, and the change of less than the predetermined denomination for each customer out of the change that has already been returned is displayed on the display unit 45 to pay to the cash underwriting unit 41. When the return determination step NN144 is subsequently executed, and it is monitored whether or not the change of less than the predetermined denomination per customer among the change that has already been returned is completed, and there is a deposit greater than the change amount Then, the change amount setting step S32 is executed, and when the change amount is less than the return amount, the return display step NN143 is executed again to display the amount that has not been paid and prompt the payment.

  When it is desired to change the use of the customer card C currently being processed from the point card CP to the change card CC, the usage pattern is changed according to the predetermined denomination setting step NN141 per return determination step NN144 for each customer. Will be changed. It should be noted that in the predetermined denomination setting step NN141 or change prohibition denomination setting step NN142 for each customer, the customer card C or the point and change information recording device 6 is provided with information indicating the usage pattern. You may form so that it may record.

  In the change amount setting step S32, the change amount (T) = 300 is set to 300 yen, which is the remaining change that has already been returned in cash by the change payment determination step S21 to the denomination change step S25.

  Then, the premier point calculation step S33 is executed, and the first rate for calculating the first point pt1 = 3% and the second rate for calculating the premier point pt2 as the second point = 5% And the added rate = 8% is multiplied by the total amount of 4100 yen to calculate the point pt = 328, and the point pt = 0 (which has already been recorded corresponding to the ID number of the change card CC) Since point consumption is desired in the point consumption desire determination step S11, the point consumption is already 0 points in the point consumption step S12) is added to calculate 328, and the point pt is set as point pt = 328. In this description, the point pt recorded corresponding to the ID number of the change card CC is consumed and is 0 by the point consumption desire determination step S11 and the point consumption step S12. If consumption is not desired, the point pt recorded corresponding to the ID number of the change card CC is not consumed, so in the premier point calculation step S33, the newly generated point pt = 328 and the change card have already been obtained. The point pt = 428 obtained by adding the point pt = 100 recorded corresponding to the CC ID number is replaced with a new point pt. Then, an additional writing determination step S36 is executed.

  If it is determined in the change record determination step S31 that the change is not recorded corresponding to the ID number of the point card CP or the change card CC, the change repayment step S34 and the point calculation step S35 are executed, and the change to be repaid. The total amount of 300 yen is returned and the change amount (T) is set to 0. Subsequently, in the point calculation step S35, the first rate for calculating pt1 = 3% and the total amount = 4100 yen are multiplied. The point pt = 123 is calculated, and the point pt = 0 (the point pt = 0 already recorded in correspondence with the ID number of the point card CP). It is already 0 points in the consumption step S12), and 123 is calculated. To set a point pt = 123 as cement pt. Then, an additional writing determination step S36 is executed. At this time, even if the customer card C to be processed currently used is the change card CC, the usage pattern of the change card CC is not changed to the point card CP, but the additional determination step S36 is performed before the change repayment step S29. The predetermined usage type setting step NN141 and change-prohibited money type setting step NN142 for each customer may be provided before the time of, and the usage pattern may be changed so that the change card CC can be used as the point card CP.

  When the postscript determination step S36 is executed following the premier point calculation step S33, it is determined whether or not recording corresponding to the ID number of the change card CC is performed, and corresponding to the ID number of the customer card C is determined. If the contents to be recorded are the same as the contents already recorded, the card withdrawal confirmation step S40 is executed without recording again, and if there is new information to be written, the recording step S37 is continued. Since there is a new point pt and change amount (T) that must be recorded in accordance with the ID number of the change card CC, the recording step S37 is subsequently executed. .

  In the recording step S37, since the newly generated point pt = 328, the date and time of recording, the total amount purchased, and the amount of cash paid have been changed, these are updated to the change card CC and the ID number of the change card CC is updated. To the history recording unit 47 in correspondence with Further, in the recording step S37, since the change amount, which is an item to be displayed on the display unit C2 of the change card CC, has been changed, the display on the display unit C2 is also changed and displayed. In this embodiment, the description on the display unit C2 displays the last transaction date and the available change amount. It should be noted that the sex, customer age, refund type for each customer, refund type for each customer, etc. that have already been recorded in correspondence with the ID number of the change card CC have not been changed and are not updated. .

  At this time, the content recorded corresponding to the ID number of the change card CC is transmitted to each history storage unit 47 via the network LAN 2 connecting the settlement machines 4 to each other, and each history storage unit 47 records.

  Next, the change recording step S38 is executed, and 300 yen, which is the change amount to be recorded calculated in the change amount setting step S27, is recorded in the history recording unit 47 in association with the ID number of the change card CC, and the display unit C2 The change amount of 300 yen recorded, that is, the change amount of 300 yen that can be used next time is displayed and described.

  In the same manner as described above, the content recorded in correspondence with the ID number of the change card CC is transmitted to each history storage unit 47 via the network LAN 2 and the history storage unit 47 records this information.

  Next, a recording notification step S39 is executed, and the fact that the recording corresponding to the ID number of the change card CC and the display on the display unit C2 is completed is sent to the display unit 45 of the settlement machine 4 and the price display unit 33 of the POS register 3. Display and notify.

  Next, a card withdrawal confirmation step S40 is executed, and it is determined whether or not the change card CC has been pulled out from the card reader / writer 36. If it is determined that the change card CC has been pulled out, the series of processing is terminated. Returns to the change record determination step S31, and then the change record determination step S31 is executed again.

  Therefore, until the customer card C is pulled out from the card reader / writer 36, the steps from the change record determination step S31 to the card withdrawal confirmation step S40 are always repeated, and when the customer pulls out the change card CC from the card reader / writer 42, the points and The change information recording process F ends.

  The above is a case where the customer uses the change card CC and uses the point pt recorded corresponding to the ID number of the change card CC at the time of payment of the purchased product as part of the payment. When the point pt = 100 recorded corresponding to the ID number of the card CC is not used as a part of the payment price, it is determined that there is no consumption hope in the point consumption hope determination step S11, and then the settlement price display step. Since S16 is executed, the point pt is processed with the point pt = 100 recorded corresponding to the ID number of the change card CC, and the newly generated point pt = 328 in the premium point calculation step S28. And point pt = 428 is set, and in step S37, a new point pt = 428 is set. It is recorded.

Next, a case where the card inserted into the card reader / writer 42 is the point card CP and the customer changes the card type from the point card CP to the change card CC will be described. It should be noted that, corresponding to the ID number of the inserted point card CP, 300 yen is recorded as change, and 100 points pt are recorded, and there is room for the number of usable times. Shall.
The customer inserts the point card CP into the card reader / writer 42 in order to change the point card CP currently used to the change card CC.

  In the card insertion determination step S1, since the point card CP has been inserted, it is determined that the card has been inserted, and the use count determination step S3 is executed.

  In the usage count determination step S3, the usage count of the point card CP is confirmed, and since it is less than the usage limit, the usage count addition step S4 is subsequently executed to increase the usage count by 1 and again by the card reader / writer 42. Is recorded on the point card CP.

  Next, the settlement determination step S5 is executed, and the change card member change button (not shown) provided in the checkout machine 4 is pressed by the customer, so it is determined that the point card CP is changed to the change card CC, and the process continues. Then, the card insertion determination step S41 is executed.

  In the card insertion determination step S41, since the point card CP has been inserted, the elapsed time determination step S43 is subsequently executed. In the card insertion determination step S41, if no card is inserted (that is, the card insertion determination step S1 is determined based on the history information that the customer card C is not inserted first), the input step S42 is executed, Obtain by manually entering the previous transaction total amount and the previous change amount from the receipt you bring. Then, an elapsed time determination step S43 is executed following the input step S42.

  In the elapsed time determination step S43, the elapsed time from the previous transaction is determined, and if the predetermined period, for example, three months or the settlement date of the store is not passed, it is continued from the previous transaction date. Since the previous information reading step S44 is executed, the previous information reading step S44 is subsequently executed. In this embodiment, since the predetermined period has not elapsed, the previous information reading step S44 is executed. However, if the predetermined period has elapsed, the point and change information recording process F is terminated.

  In the previous information reading step S44, the previous total amount 2000 yen read by the card reader / writer 42 from the point card CP, the previous change amount 300 yen, and the recorded point pt 100 points are read.

  The point reading step S45 is executed following the previous information reading step S44, and the first point pt1 100 points recorded corresponding to the ID number of the inserted point card CP is read. Set pt to the point pt = 100.

  Subsequently, the previous change amount replacement step S46 is executed, and the previous change information read based on the ID number of the point card CP in the previous information reading step S44 is replaced with new change information (s) = 300. Subsequently, the denomination amount setting step S47 is executed.

  In the subsequent denomination amount setting step S47, the predetermined denomination is set to 10,000 yen and 10,000 yen, 5,000 yen, 1,000 yen, 5 hundred yen, 1 hundred yen, 50 yen, 10 yen. Set each denomination (i) of 5 yen and 1 yen to 0, that is, 10,000 yen, and set the return number N for each denomination (i) to 0. The denomination (i) set at this time is i = 0 represents 10,000 yen, i = 1 represents 5,000 yen, i = 2 represents 1,000 yen, and i = 3 represents 500 yen. I = 4 represents 1 hundred yen, i = 5 represents 50 yen, i = 6 represents 10 yen, i = 7 represents 5 yen, and i = 8 represents 1 yen. N represents the number of sheets, and is represented by a natural number such as N = 0, 1, 2, 3, 4,. Accordingly, the return number N [i] represents, for example, that the return number 3 [2] when i = 2 and N = 3 is three thousand yen, that is, 3000 yen. The predetermined denomination represents the amount of change desired to be recorded and returned in correspondence with the ID number of the point card CP when the customer receives the change. If the seed is 1000 yen, a change of less than 1000 yen, that is, up to 999 yen is recorded as change information corresponding to the ID number of the point card CP. Accordingly, at this time, although the card type is the point card CP, the change information is substantially recorded, so that it is regarded as the change card CC.

  Next, in the predetermined denomination determination step S48, the upper limit predetermined denomination is compared with the predetermined denomination for each customer, and if the predetermined denomination for each customer is larger than the upper limit predetermined denomination, the predetermined denomination setting step S49 is executed. In other cases, the change payment determination step S50 is executed. Since the predetermined denomination per customer is 1000 yen and the upper limit predetermined denomination is 5000 yen, the change payment determination step S50 is subsequently executed. When the upper limit predetermined denomination is, for example, 500 yen, the predetermined denomination setting step S49 is subsequently executed. Although not executed in this embodiment, the case where the upper limit predetermined denomination is 500 yen will be described below. In the predetermined denomination setting step S49, the predetermined denomination for each customer recorded corresponding to the ID number of the change card CC is set as the upper limit predetermined denomination. Therefore, the predetermined denomination for each customer is treated as 500 yen which is the upper limit predetermined denomination while the point and change information recording process F is being executed. And by replacing the predetermined denomination for each customer with the upper limit predetermined denomination in this way, when the total amount of change card CC deposit that is a duty to report deposit to the tax office on the store side exceeds 7 million yen, etc. By changing the denomination of the upper limit predetermined denomination to the denomination of the predetermined amount, the change amount to be returned in cash is increased, and the amount of change information recorded corresponding to the ID number of the change card CC is reduced and deposited It is possible to adjust the total amount to 7 million yen or less.

  Subsequently, a change payment determination step S50 is executed. In the change payment determination step S50, the product of the return amount N [i] and the customer denomination amount represented by the denomination (i) from 2000 yen which is a positive unsettled amount (s) (surplus price) including 0 yen is calculated. The subtracted comparison formula is compared with the amount of the predetermined denomination. That is, 2000, which is a comparison expression “2000−10000 × 0” obtained by subtracting 0, which is the return number N = 0, denomination (i) = 10000, from surplus price (s) = 2000, and 10000 which is the amount of the predetermined denomination. As a result, the amount of the predetermined denomination is larger, and therefore the predetermined denomination return step S52 is executed. In the predetermined denomination return step S52, the denomination (i) 10,000 yen of the currently processed return number N = 0 is returned (ie, in this case, it is 0, so it is not substantially returned).

Following the predetermined denomination return step S52, a predetermined denomination determination step S54 for each customer is executed, and the denomination (i) = 10,000 yen processed in the change payment determination step S50 to the predetermined denomination return step S52 is predetermined for each customer. As a result of determining whether or not it is a denomination, the denomination changing step S55 is executed because it is not 1000 yen which is a predetermined denomination for each customer.
In the denomination changing step S55, the denomination (i) = 10000 currently processed is changed to the denomination (i) = 5000 which is the next denomination, and then the change payment determination step S50 is executed again.

  In the change payment determination step S50, the denomination (i) is changed to 5,000 yen as in the case of the denomination (i) = 10000 yen, so the denomination (i) set in the denomination amount setting step S47 is The amount of the predetermined denomination is 2000, which is a comparative expression “2000−5000 × 0” obtained from the return number N = 0, denomination (i) = 5000, surplus price (s) = 2000 when it is 5,000 yen. Compare with 5000. As a result, since the amount of the predetermined denomination is larger, the predetermined denomination return step S52 is subsequently executed.

  In the predetermined denomination return step S52, the currently processed return number N = denomination (i) 5,000 yen is returned (in this case, it is 0, so it is not substantially returned).

  Following the predetermined denomination return step S52, the predetermined denomination determination step S54 for each customer is executed again, and the denomination (i) = 5,000 yen processed in the change payment determination step S50 to the predetermined denomination return step S52 is determined for each customer. As a result of determining whether or not the denomination is the predetermined denomination, the denomination changing step S55 is executed because the predetermined denomination per customer is not 1000 yen.

  In the denomination changing step S55, the denomination (i) = 5000 currently processed is changed to the denomination (i) = 1000 which is the next denomination, and the change payment determination step S50 is subsequently executed again.

  In the change payment determination step S50, the denomination (i) is changed to 1,000 yen. Therefore, the return number N = 0 when the denomination (i) set in the denomination amount setting step S47 is 1,000 yen, From the denomination (i) = 1000 and the surplus value (s) = 2000, the comparison formula “2000-1000 × 0” is obtained, and the comparison formula “2000-1000 × 0” is compared with 1000 which is the amount of the predetermined denomination. To do. As a result of comparison, since the comparison formula is larger, the return number addition step S51 is executed continuously, the return number N is added by one to set the return number N = 1, and then the change payment determination step S50 is performed again. Execute.

  In the change payment determination step S50, since the return number N = 1, the comparison formula “2000−1000 × 1” 1000 is compared again with the predetermined denomination amount 1000, and as a result of comparison, the comparison formula Since 1000 which is “2000−1000 × 1” and 1000 which is the amount of the predetermined denomination are the same, the return number addition step S51 is executed again, the return number N is added by 1 and the return number N = 2, Subsequently, the change payment determination step S50 is executed again.

  In the change payment determination step S50, since the return number N = 2, the comparison formula “2000−1000 × 2” is compared again with the predetermined denomination amount of 1000, and as a result of comparison, the comparison formula Since “2000-1000 × 1” is smaller, the predetermined denomination return step S52 is subsequently executed.

In the predetermined denomination return step S <b> 52, the currently processed return number N = 2 denominations (i) 2,000 yen are returned from the change payment unit 44.
Therefore, at this stage, the customer has received 2000 yen return, and the remaining amount is 0 yen.

  Next, the predetermined denomination determination step S54 for each customer is executed again, and it is determined whether or not the denomination (i) = 1,000 yen processed in the change payment determination step S50 to the predetermined denomination return step S52 is the predetermined denomination for each customer. As a result, since the predetermined denomination per customer is 1000 yen, the change card determination step S56 is subsequently executed.

  In the change card determination step S56, the change amount that is the remainder of the change that has already been returned in cash as the previous information in the change payment determination step S50 to the denomination change step S55 is set as change amount (T) = 0, and then Display step S57 is executed.

  In the display step S57, the change amount (T) paid out last time, that is, the change amount (T) = 0 calculated in the denomination amount setting step S47 to the change amount setting step S56 is displayed on the price display unit 33 and the display unit 45. . Accordingly, the price display unit 33 and the display unit 45 display the amount calculated in the change amount setting step S56. When the display step S57 is executed subsequent to the change return determination step S59, the shortage amount which is the change amount obtained by subtracting the amount received in the change return reception step S58 is displayed.

  Next, a change return acceptance step S58 is executed. The change return acceptance step S58 is a step of accepting payment of the previous change amount (T) = 0 by the customer, and the change amount is newly issued or changed from the point card CP. The amount stored as change information to the CC. In this example, since the change amount (T) = 0, the change return acceptance step S58 executes the next step without waiting for payment. In the change return acceptance step S58, when waiting for payment, the shortage amount is calculated by subtracting the amount received from the previous change (T).

  In the change change determination step S59, it is monitored whether or not the received amount has reached the previous change amount (T), but since the change amount (T) = 0 already, the previous change amount (T) has been reached and the change is immediately made. The replacement step S60 is executed. In the change return determination step S59, if the previous change amount (T) has not been reached, the display step S57 is executed again.

  Accordingly, the display step S57 to the change return determination step S59 can always wait for payment from the customer until the previous change amount (T) is paid, and when the amount has been reached, the next step can be executed. .

  Next, change change step S60 is executed. In change change step S60, since the previous change amount (T) = 0 paid by the customer is stored in correspondence with the ID number of the change card CC, the change information of the POS register 3 control unit (not shown) is used. A change amount (T) is temporarily set to 0 and stored in a storage area (not shown).

  Following the change replacement step S60, a premier point calculation step S61 is executed to generate points corresponding to the total amount = 2000 used by the customer last time. The second rate for calculating the premier point pt2, which is the point, is multiplied by the previous total amount = 2000 to calculate the point pt = 100, and the calculated point pt = 100 is already added to the ID number of the point card CP. The point pt = 100 recorded correspondingly is added to calculate a new point pt = 200, and the point pt is replaced with 200. Therefore, the point pt added in the premier point calculation step S61 corresponds to the ID number of the change card CC using the change card CC because the first point pt1 has already occurred at the previous shopping. The first point pt1 and the second point when the change card CC is used are calculated by calculating only the premier point pt2, which is the second point generated by recording, and adding it to the point pt generated so far. This means that the premier point pt2, which is a point of the above, is added. Following the premier point calculation step S61, a point recording step S62 is executed.

  In the point recording step S62, the new point pt = 200 calculated in the premier point calculating step S61 is recorded in the history recording unit 47 in association with the ID number of the change card CC, and also recorded in the display unit C2. = 200 is displayed and described. Of course, when there is no need to record the point pt = 200 on the display unit C2 and show it to the customer, it is not necessary to display it on the display unit C2, and it can be set according to the environment such as a store.

Then, the information recorded corresponding to the ID number of the change card CC in the point recording step S62 is transmitted to all the history storage units 47 via the network LAN 2 connecting the settlement machines 4 to each other, and each history storage unit 47 Then, the same information is recorded. The network LAN 2 connects the settlement machines 4, and all the settlement machines 4 are provided with a history recording unit 47. Then, the settlement machine 4 accepts the customer card C (including the case where the card reader / writer 36 of the POS register 3 accepts the customer card C and the settlement machine 4 receives the received information). The settlement machine 4 corresponds to the ID number of the customer card C. The history information, which is all information to be recorded, such as point information, change information, and “Please refer to the Excel DB item”, is transmitted to all other settlement machines 4 via the network LAN 2 and other settlement machines. 4, the received history information is recorded in the history recording unit 47 corresponding to the ID number of the customer card C. Then, in each of the settlement machines 4, when the customer card C is received next time, even if the customer card C was processed by the other settlement machine 4 last time, the customer card accepted by the other settlement machine 4 Processing can be performed without inquiring C history information. That is,
All the history recording units 47 can share the same history information for the customer card C. Further, when the history recording unit 47 is not provided in all the settlement machines 4 and is provided only in one settlement machine 4, the settlement machine 4 that is not provided with the history recording unit 47 is a customer When the card C is received, the history information recorded in correspondence with the ID number of the received customer card C is inquired to the history recording unit 47, and information necessary for processing such as change information and point information is transmitted via the network LAN2. Get and process. Furthermore, when it is provided in one settlement machine 4 in a group formed by several settlement machines 4, the history information of the customer card C is also shared by all installed history recording units 47. Thus, the information of the customer card C received by the checkout machine 4 is recorded. Then, when the customer card C is received by the checkout machine 4 that does not provide the history recording unit 47, the history recording unit 47 of the group to which the customer belongs is inquired.

When the point recording step S62 is completed, a change recording step S38 is subsequently executed. The operation after the change recording step S38 is as described above.
Therefore, the card insertion determination step S41 to the point recording step S62 are steps performed when the customer changes the point card CP that has been used so far to the change card CC.

Next, the point and change information recording device 6 will be described. Hereinafter, the point and change information recording device 6 is referred to as a recording device 6.
As shown in FIG. 10, the recording device 6 can be used in connection with a conventional POS register device 100 that is normally used, and can receive a total price signal purchased by the customer from the POS register device 100. The recording device 6 includes a card reader / writer 61, a cash accepting unit 62, a change return port 63, a control unit 64, a money insertion port 65, a bill insertion port 66, and a display unit 67.

  The card reader / writer 61 is the same as the card reader / writer 36, and the card insertion slot is opened, and the customer card C is inserted and can be read / written by the read / write unit.

  The cash accepting unit 62 includes a bill accepting unit 62a and a money accepting unit 62b. Then, the cash accepting unit 62 receives information about the amount of money deposited each time there is a deposit from the bill insertion slot 66 to the bill acceptance unit 62a and from the money insertion slot 65 to the money acceptance unit 62b. And output to the control unit 64. The banknote accepting unit 62a can store the amount of money deposited, and when there is an instruction to return the cash, the number of banknotes specified for each type can be returned from the insertion slot. Similarly, the money underwriting unit 62b can store the deposited money for each type of money, and can return the number specified for each type when there is an instruction to return the money.

The change return port 63 is a return port for returning money to the customer, and money returned from the money accepting unit 62b can be sent and returned.
The display unit 67 is the same as the display unit 2 and can display various types of information under the control of the control unit 64.

  The control unit 64 can control the reading / writing of the customer card C by the card reader / writer 61, the transmission / reception of signals with the conventional POS register device 100, the calculation of the inserted cash and the cash to be returned, and the like, as in the POS register 3 described above. It is.

  Below, control of the control part 64 is demonstrated. In the recording device 6, the calculation processing of the purchase price purchased by the customer, which was performed by the POS register 3, is performed by the connected conventional POS register device 100. In addition, the recording device 6 performs the same function as the POS register 3 by exchanging signals with the POS register device 100 to read / write information to the customer card C, accept payment of purchase price, refund change, etc. Is connected to the conventional POS register device 100, the customer card C according to the present invention can be easily introduced even in a store where the conventional POS register device 100 is installed.

  Hereinafter, the point and change information recording process F will be described based on the signal exchange between the recording device 6 and the POS register device 100. However, in the description, the description of the points that overlap with the point of the POS register 3 and the change information recording process F described above will be omitted.

  The customer pays for the purchase using the POS register device 100 in the same manner as the POS register 3 in order to settle the purchase price. In the POS register device 100, the store clerk causes the POS register device 100 to calculate the total purchase price in order to settle the products purchased by the customer. At this time, the customer inserts the customer card C into the card reader / writer 61 of the recording device 6.

  In the recording device 6, the control unit 64 has started the point and change information recording process F, and determines the customer card C in the card insertion determination step S1. A series of steps up to settlement determination step S5 is executed.

  Hereinafter, the normal settlement will be described.

  Subsequent to the settlement determination step S5, the processing from the change information determination step S7 to the point reading step S10 for the customer card C is performed.

  Next, the point consumption desire determination step S11 is executed. This point consumption desire determination step S11 may be configured such that a customer presses a selection button (not shown) provided on the recording device 6, and the clerk listens to the customer's intention and the POS register device 100. It may be determined by pressing a selection button (not shown) provided on the recording device 6 and receiving a signal indicating whether or not the recording device 6 wishes to consume from the POS register device 100.

  Next, in the point consumption step S12 to be executed, the card reader / writer 61 consumes the change recorded for each point and each card according to the information read in the change information reading step S9 and the point read step S10. Process to settle as part.

  Then, the settlement price display step S16 to the predetermined denomination setting step S20 to be executed next are processed in the same manner as the processing of the POS register 3, but the display is displayed on the display unit 67 in the settlement price display step S16.

  The change payment determination step S21 to the denomination change step S25 are processed in the same manner as in the case of the POS register 3, but when the predetermined denomination return step S23 returns the change, the type and number of money returned by the control unit 64. To the cash accepting unit 62, for banknotes, a predetermined number of seeds are returned from the bill accepting slot 66 from the banknote accepting unit 62a, and for coins, a predetermined number of predetermined types are returned from the money accepting unit 62b. It is done by letting it return from.

  The change card determination step S26 to the point calculation step S35 are also performed in the same manner as the processing by the POS register 3, but the points performed in each step of the premium point calculation step S28, the point calculation step S30, the premier point calculation step S33, and the point calculation step S35 In the calculation, the information of the first point pt1 may be used by inputting the point information calculated by the POS register device 100 by the recording device 6, or is the purchase price input from the POS register device 100. It may be calculated from the total amount. That is, when the recording device 6 is newly introduced, the calculated point information can be used if the POS register device 100 conventionally used in the store has a point giving function. Further, if the POS register device 100 used conventionally does not have a point grant function, it may be calculated from the total purchase price input by the recording device 6. Then, instead of receiving the point information directly from the POS register device 100 used conventionally, the first point (for example, 3%) for calculating the first point pt1 is received and the first point is received. You may form so that pt1 may be calculated.

  Similarly, each step from the predetermined denomination return step S36 to the point recording step S62 is performed in the same manner as the processing by the POS register 3.

  In each step, for example, if the information necessary for processing is not available in the recording device 6 such as the total amount of the purchase price, the necessary information is received from the POS register device 100 and processed. To do.

  Accordingly, the recording device 6 is a recording device 6 which is partly independent of the POS register 3, and the functions of the POS register 3 are satisfied by the connected POS register device 100 and the recording device 6. Is.

  The recording device 6 shown in FIG. 10 is formed of a card reader / writer 61, a cash accepting unit 62, a change return port 63, a control unit 64, a money insertion port 65, a bill insertion port 66, and a display unit 67. 4 may be formed without providing the cash underwriting unit 62 as in the settlement machine 4 shown in FIG. 4, and may be formed so that the price is accepted by the conventional POS register device 100. It is sufficient that the customer card C reads and writes data, accepts paid cash, and displays various information by the conventional POS register device 100 and a store clerk. Similarly, a display unit 67 may be provided in the recording device 6 and a display function may be added. Although cash is accepted by adding the cash accepting unit 62, cash change is returned to the store clerk. The recording device 6 may be provided with at least a card reader / writer 61 and a control unit 64, and only other necessary functions may be selectively added and used.

  Next, a case where notification is made when the total change amount, which is the accumulated amount of change amounts recorded in correspondence with the ID numbers recorded on all change cards CC, exceeds the upper limit amount will be described with reference to FIG.

  The central management computer 2 is provided with a recording device (not shown) which is a change amount storage means for recording the change amount recorded corresponding to the ID number of the change card CC for each change card CC. The central management computer 2 forms the change amount recorded in the change recording step S38 each time.

  Then, in the central management computer 2, as shown in FIG. 9A, the change information for each change card CC recorded in this way is totalized by a total change amount totaling step NN120 which is a totaling means. That is, the total change sum totaling step NN120 is a step of reading the change amount for each change card CC from the recording device which is the change amount storage means and adding and totaling the total change amount summing step NN120. The total change amount stored corresponding to the ID number of the change card CC is calculated.

  Next, notification determination step NN121 is executed. In the notification determination step NN121, an upper limit amount to be compared with the total change amount is set in advance, and the total change amount aggregated in the total change amount aggregation step NN120 is compared with the set upper limit amount. If it is large, it is instructed to continuously sound an alarm or display on the price display unit 33 and / or the display unit 45, etc., and the upper limit predetermined amount is changed to a predetermined upper limit predetermined denomination. It is used as the upper limit predetermined denomination when it is determined in the predetermined denomination determining step S19. Thus, by setting the upper limit predetermined denomination and executing the predetermined denomination determining step S19 and subsequent steps, it is possible to reduce the total change amount of the change amount recorded corresponding to the ID number of the customer card CC. This upper limit is the upper limit of the amount deposited from all customer cards as change, and the amount beyond which the store does not accept the deposit.

  Further, as shown in FIG. 9B, a total amount determination step NN130 and a total amount display step NN131 are provided after the total change amount totaling step NN120. The total amount determining step NN130 is a step for determining whether or not to display the total change amount totaled in the total change amount totaling step NN120. When a display designation switch (not shown) provided in the central computer 2 is pressed in advance. Subsequently, the total amount display step NN131 is executed. If it is not the phase, the total amount display step NN131 is not executed and the process returns.

  The total amount display step NN131 is a step of displaying the total change amount calculated in the total change amount calculation step NN120 on a display (not shown) provided in the central computer 2.

  Accordingly, when a display designation switch (not shown) for displaying the total amount is pressed from the central computer 2, since the display designation switch is pressed in the total amount determination step NN130, the subsequent total amount display step NN131 is executed, and the total change amount totaling step The total change amount collected by the NN 120 is displayed on the display of the central computer 2. Of course, it may be printed out as well as displayed.

  Thereby, on the store side, it becomes possible to see the total change amount recorded corresponding to the ID number of the issued change card CC, and an appropriate instruction can be issued.

  Further, the total amount determination step NN130 and the total amount display step NN131 may be provided between the total change amount totaling step NN120 and the notification determination step NN112 shown in FIG.
