Abstract

PURPOSE:To enable the long-term use of a card and to reduce the number of the cards to be issued by adding an input amount to the remainder of the card read by a card reader / writer when the prepaid amount is inputted corresponding to the key input of a reception key. CONSTITUTION:When the card presented by a customer is loaded to a card reader / writer 4 and the sale of a commodity bought by the customer is registered, the total amount of the customer is calculated by a store processor 2 and further, the fraction of the total amount is calculated. The amount of the fraction is subtracted from the card remainder of the customer and the customer pays an amount subtracting the fraction amount from the total amount. On the other hand, when the reception key is operated and the prepaid amount is inputted in the state of loading the card to the card reader / writer 4, the input amount is added to the card remainder of the card. Accordingly, since prepaid money is paid when the remainder of the card is reduced, the remainder of the card can be increased and the card can be used for a long time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to product sales such as electronic cash registers and POS (point of sale) systems in which the electronic cash registers are centrally managed by a host controller. The present invention relates to a data processing device, and particularly relates to a device that uses a card to settle fractional amounts incurred in paying for shopping.

[Prior Art] Conventionally, as a method of settling fractional amounts resulting from payment of shopping charges using a card that can store information, for example, Japanese Patent Laid-Open No. 6
As seen in Publication No. 3-249293, there is a method in which the fractional amount of change when a customer pays is accumulated and recorded on a card, and a method in which the customer uses a card with a predetermined limit on the amount. Two methods have been considered: making a purchase with the limit amount or an amount close to the limit amount, and if a fractional amount occurs at the time of payment, the fractional amount is subtracted from the card's limit amount and the remaining amount is recorded.

However, in the former method, when the accumulated amount of money on the card reaches a certain amount, the card must be operated in such a way that the card can be refunded in cash or exchanged for a certain product. On the other hand, even with the latter method, if the card balance became 0 yen or less, the card could no longer be used.

[Problem to be solved by the invention] As described above, in the conventional technology, not only when the card is lost or damaged, but also when the accumulated amount on the card reaches a certain amount or the remaining amount against the limit is 0 yen or less If this happens, the card can no longer be used and a new card must be issued. For this reason, a large number of cards were required to operate the system, and high costs were unavoidable.

Additionally, if a card is lost or damaged, a new card will be issued, but this is not guaranteed because the balance of the old card is only recorded on that card. Therefore, if the card is lost or damaged, the customer suffers a loss, resulting in poor service quality.

Therefore, the present invention makes it possible to use a card that can process fractional amounts generated when paying for shopping for a long period of time, unless it is lost or damaged. The purpose is to provide a product sales data processing device that can reduce costs and prevent high costs.

Furthermore, the present invention is a product that can reliably guarantee the balance of the card and record it on a new card even if the card is lost or damaged, thereby improving serviceability and increasing the card usage rate. The present invention aims to provide a sales data processing device.

[Means for Solving the Problems] The first invention of the present application is a registration means for registering sales data of a product in a memory and displaying it on a display based on information regarding the product for sale inputted through an input unit; A totalizing means for calculating the total amount for each transaction of products registered for sale by the registration means, and a receipt issuing means for printing and issuing the registration information by the registering means and the total amount by the totalizing means on a receipt according to the transaction closing operation. The product sales data processing device includes a scent card that stores information such as card number and balance data, a cartridge writer that reads and writes information to and from the card, and a fraction of the total amount calculated by a totaling means. a fractional amount extraction means for extracting the amount; a payment amount display means for displaying the total amount excluding the fractional amount extracted by the extraction means on a display; and a card reader/writer to display the fractional amount extracted by the extraction means. A card balance updating means that subtracts the amount from the balance of the card read, a deposit key, and when the advance payment amount is input in accordance with the key input of the deposit key, the input amount is added to the balance of the card read by the card reader/writer. The card balance adding means is also provided.

A second invention of the present application provides the above-mentioned card, the above-mentioned card reader/writer, a calculation means for adding the balance of the card read from the card reader/writer to the total amount calculated by the above-mentioned totalization means, and a calculation means calculated by the calculation means. A fractional amount extraction means for extracting a fractional amount of the added amount; a payment amount display means for displaying on a display the added amount excluding the fractional amount extracted by the extraction means; and a payment amount displaying means for displaying the fractional amount extracted by the extraction means. The card balance updating means writes the balance of the card read by the card reader/writer.

In addition to the first or second invention, a card management file for recording the card number and card balance of the card read by the card reader/writer, an update key, and an old card according to key input of the update key are provided. A card updating means is provided for reading the latest card balance corresponding to the card number of the old card from the card management file and writing it to the new card installed in the card reader/writer when an update from the card to the new card is instructed. It's convenient.

In addition to the first or second invention, the invention also includes a clock circuit that stores the current date, a card management file that records the card number and balance of the card read by the card reader/writer, and the last date of handling. It is desirable to provide a final date setting means for handling the date of the clock circuit and setting the date in the card management file as the final date when the card balance is updated by the card balance updating means. .

[Function] According to the first invention of the present application, when the customer inserts the card presented in the card reader/writer and registers the sale of the product purchased by the customer, the customer's total = [amount is calculated, Furthermore, a fractional amount of the total amount is extracted. Then, this fractional amount is subtracted from the customer's card balance, and the customer pays the amount obtained by subtracting the fractional amount from the total amount. - On the other hand, when the deposit key is operated with the card attached to the card reader/writer to input the amount of the advance payment, the input amount is added to the card balance of the card.

Therefore, if your card balance is getting low, you can increase it by paying the advance payment.
You will be able to use your card for a long time.

According to the second invention of the present application, when the customer inserts the card presented into the card reader/writer and registers the sales of the products purchased by the customer, the total price of the customer is calculated,
Furthermore, the balance of the card will be added to this total amount. Then, a fractional amount of this added amount is extracted, and the fractional amount is written to the card as a card balance. On the other hand, the customer will pay the amount obtained by subtracting the fractional amount from the additional amount. Therefore, the fractional amount is carried over as the card balance until the next purchase and is paid at the next purchase, so only fractional amounts less than a certain unit are always recorded on the card, allowing the card to be used for a long time.

The CPU 31 of each POS terminal 1 is programmed to execute the advance payment deposit processing shown in FIG. 8 by inputting the deposit key 59 while the "registration" mode is selected by the mode switch 37. .

That is, when the key data of the deposit key 59 is taken in through the keyboard circuit 40, the process is started, and after confirming that the product purchased by the customer is not being registered for sale, the depositing flag F3 is set to "1". In this state, wait for the next key input. When it is detected that the card key 61 has been operated, it sets the card flag F1 and
The card data read by the card reader/writer 4 is written into the card buffer 75 via the card reader/writer control circuit 36. Also, the balance data in the card data is written into the balance memory 80, and the next key input is awaited.

Further, when it is detected that the amount key 52 is operated while the depositing flag F3 is set, the state of the card flag F1 is checked. If the card flag F1 is set, it is determined whether numerical data is stored in the number buffer 74 or not. If numeric data other than 0 is stored, the numeric data is transferred to the work memory 76 as the advance payment amount and waits for the next key input. Note that when the card flag F1 is reset to "0" or when no numerical data is stored, the key operation of the amount key 52 is treated as an error.

On the other hand, when it is detected that the signature key 58 has been operated while the deposit flag F3 is set, the state of the card flag F1 is also checked. And card flag F
If 1 is set, it is determined whether numerical data is stored in the numeric buffer 74 or not. And 0
If other numerical data is stored, the numerical data is compared with the cashier number in the cashier number memory 73. If the two match here, the advance payment deposit arrangement message is edited based on the card data in the card buffer 75 and the advance payment amount data in the work memory 76, and the inline processing is completed! An inquiry is made to the store processor 2 via I3. If an ACK response is returned from the store processor 2 in response, the contents of the card buffer 75 are updated using the balance data included in the response message as the card balance, and the contents of the buffer 75 are transferred to the card read/writer control circuit 36. is sent to the card reader/writer 4 via the card and written to the card (card balance addition means). Also, the card number in the card buffer 75.

Print data for advance payment deposit is edited from the name and card balance, the advance payment amount in the work memory 76, and the balance data in the balance memory 80, and outputted to the printer drive circuit 44, and a receipt for advance payment deposit shown in FIG. 12 is produced. Print and issue R1. Thereafter, the card flag F1 and the depositing flag F3 are reset, and this process is ended.

On the other hand, store processor 2
If a NAK response is returned from , there is an error in the card data or advance payment data in the interim message, so an error message is displayed on the display 41 and the process is terminated.

In addition, in response to the input of the signature key 58, the card flag F1
If it has been reset to "0" or if numerical data is not stored, the key operation of the signature key 58 is treated as an error. Also, if the numerical data does not match the cashier number, the key operation of the signature key 58 is treated as an error.

Further, the CPU 31 of each POS terminal 1 is programmed to execute the card update process shown in FIG. 9 by key input of the update key 60 while the "registration" mode is selected by the mode switch 37. . That is, the process is started when the key data of the update key 60 is taken in via the keyboard circuit 40, and after confirming that the product purchased by the customer is not being registered for sale, the update flag F4 is set to "1". In this state, wait for the next key input. When it is detected that the card key 61 has been operated, the card flag F1 is set and the card data read by the card reader/writer 4 is transferred to the card buffer 7 via the card reader/writer control circuit 36.
75 and waits for the next key input.

Further, when it is detected that the number key 51 has been operated while the updating flag F4 is set, it waits for 13-digit numerical data to be input. When the 13-digit numerical data is input, the numerical data is transferred to the work memory 76 as the card number of the old card, and the next key input is awaited.

On the other hand, when it is detected that the signature key 58 has been operated while the updating flag F4 is set, the state of the card flag F1 is checked. If the card flag F1 is set, it is determined whether numerical data is stored in the number buffer 74 or not. If numerical data other than 0 is stored, the numerical data is compared with the cashier number in the cashier number memory 73. If both match here, card buffer 7
5 and the old card number data in the work memory 76, a card update interim message is edited and an inquiry is made to the store processor 2 via the inline line 3. If an ACK response is returned from the store processor 2 in response, the contents of the card buffer 75 are updated using the balance data included in the response message as the card balance, and the contents of the card buffer 75 are controlled by the card reader/writer. It is transmitted to the card reader/writer 4 via the circuit 36 and written into the card (card update means). Also,
Card number in card buffer 75 (new card number) 1
Name, card balance (written amount), and work memory 7
The card update print data is edited from the old card number in 6 and outputted to the printer drive circuit 44, and a card update receipt R2 shown in FIG. 13 is printed and issued. After that,
The card flag F1 and the updating flag F4 are reset, and this process ends.

On the other hand, store processor 2
If a NAK response is returned from , there is an error in the card data or old card number data in the makeshift message, so an error message is displayed on the display 41 and the process is terminated.

In addition, in response to the input of the signature key 58, the card flag F1
If it has been reset to "0" or if numerical data is not stored, the key operation of the signature key 58 is treated as an error. Also, if the numerical data does not match the cashier number, the key operation of the signature key 58 is treated as an error.

Further, the CPU 31 of each POS terminal 1 is program-controlled so as to execute the sales process shown in FIG. 10 by inputting a predetermined key while the "registration" mode is selected by the mode switch 37. That is,
When the key data of the card key 61 is taken in via the keyboard circuit 40, the card flag F1 is set, and the card data read by the card reader/writer 4 is transferred to the card buffer 75 via the card reader/writer control circuit 36. Write. Also, the card balance in the card data is written into the balance memory 80, and the next key input is awaited.

On the other hand, when the key data of the department key 53 is taken in via the keyboard circuit 40, the registration flag F2 is set, and the sales data of this department registered product is cumulatively processed in the department registration memory 71. In addition, the sales amount can be calculated using the 7
Add to 2.

Further, the department code and sales amount are displayed on the display 41, the printer 43 is driven to print them on the receipt, and the next key input is waited.

When the key data of the subtotal key 54 is taken in via the keyboard circuit 40, it is confirmed that the registration flag F2 is set. After that, the state of the card flag F1 is checked. If the card flag F1 has been reset, the customer does not process fractional amounts of shopping charges using a card, so normal subtotal key processing and closing key processing are executed.

When the card flag F1 is set, the total amount in the word totalizer 72 is first divided by the fraction unit in the fraction unit memory 79, and the remainder is stored as a fraction amount in the fraction amount memory 78 (fraction amount means of extraction). Next, the fractional amount is subtracted from the balance data in the balance memory 80 and the difference is stored again in the balance memory 80 (card balance update means). However, if the balance data in the balance memory 80 is negative at this time, it is impossible to process the fractional amount of the shopping price using the card, so the process moves to normal subtotal key processing and closing key processing.

If the balance data in the balance memory 80 is 0 or more, the fractional amount in the fractional amount memory 78 is subtracted from the total amount in the totalizer 72, and the difference is stored in the payment amount memory 77 as the payment amount. Then, display this payment amount on display 4.
1 (payment amount display means). The printer 43 is also driven to print the total amount, fractional amount, and payment amount on the receipt.

Thereafter, the system waits for key input on the deposit/cash key 55.

When the deposit/cash total key 55 is input to issue a command to screen transactions by cash settlement, change is calculated by subtracting the payment amount from the deposit amount, and the change is displayed on the display 41. It should be noted that the deposit amount is the numeric data if it has been entered using the numeric key 51 immediately before the key input of the deposit/cash total key 55, and the content of the payment amount memory 77 if it has not been entered. Next, the printer 43 is driven to print the deposited amount, change, and balance data in the balance memory 80 on a receipt, thereby issuing a customer receipt R3 shown in FIG. 14. If the balance data is less than the unit amount stored in the fraction unit memory 79, a receipt R4 is issued after printing a predetermined message as shown in FIG.

At the same time, the drawer 45 is opened. Further, after updating the card balance in the card buffer 75 to the balance data in the balance memory 80 and updating the last handling date to the current date stored in the clock circuit 34, the card buffer 75
The contents are sent to the card reader/writer 4 via the card reader/writer control circuit 36 and written into the card. Thereafter, the contents of the card buffer 775 are incorporated into the sales information message and sent to the store processor 2 via the inline line 3.
and end this process.

On the other hand, the CPU 1 of the store processor 2 is programmed to execute the processing shown in FIG. 11 when a message is input from each POS terminal 1 via the inline line 3. In other words, when an advance payment arrangement message is received from each POS terminal 1, after confirming that the advance payment data in the message is greater than 0 yen, card management is performed using the card number included in the card data in the message. Search card number area B1 of file 5. If a card number corresponding to area B1 is set, advance payment area B corresponding to that card number
3 and the contents of balance area B5 are updated by adding the prefix amount in the message.

After that, ACK the balance data in the balance area B5 above.
It is incorporated into a response message and sent back to the POS terminal 1 that made the inquiry, and this process is completed.

In addition, if the advance payment amount in the message is less than 0 yen, or if the corresponding card number is not set in card number area B1 of card management file 5, a NAK response will be sent to the POS terminal 1 that made the inquiry. Reply and end this process.

When a card update interim message is received from each POS terminal 1, after confirming that the old and new card numbers are included in the message, the card number area B1 of the card management file 5 is searched using these old and new card numbers. . If both card numbers corresponding to the above area B1 are set, the front bag amount area B3 corresponding to the old card number. The contents of the last handling date area B4 and the balance area B5 are moved to the same area corresponding to the new card number, and the Lou code of the old card number is deleted. After that,
The balance data in the balance area B5 corresponding to the new card number is incorporated into the ACK response message and sent back to the POS terminal 1 that made the inquiry, and this process ends.

If at least one of the old and new card numbers does not exist in the message, or if the corresponding card number is not set in card number area B1 of the card management file 5, a NAK will be sent to the POS terminal 1 that made the inquiry.
Send a response and end this process.

Upon receiving the sales information message from each POS terminal 1,
Determine whether card data exists in the message. If it exists, the card number area B of the card management file 5 is used with the card number included in the card data.
1 and select the balance area B5 corresponding to the card number.
Change the contents to the balance data in the card data. Further, the contents of the handling last date area B4 corresponding to the card number are changed to the current date stored in the clock circuit 34 (last date setting means). Thereafter, various files in the disk memory 15 are updated based on the sales information in the message, and this process is completed.

Note that if the card data is not included in the message, sales update processing is immediately performed and this processing is terminated.

In this embodiment configured in this way, the store manager issues a card with the card number etc. recorded in advance to the customer who wishes to use the card, and also operates the keyboard 22 of the store processor 2 to input the card. Set the corresponding card number 1 name and address in management file 5. After receiving a card, the customer hands the card and the appropriate advance payment to the clerk. The clerk first presses the deposit key 59 on the POS terminal 1. Next, a card is inserted into the card reader/writer 4 and the card key 61 is pressed. Then, the card data of the card is stored in the card buffer 75. At this time, the content of the balance memory 80 is "0". Next, the clerk enters the amount of the advance payment and presses the amount key 52. Then, the advance payment amount is stored in the work memory 76.

Next, the clerk enters his or her own cashier number and presses the signature key 58. Then, an advance payment matching message is transmitted to the store processor 2, and the advance payment amount is stored in the advance payment amount area B3 and the balance area B5 corresponding to the corresponding card number of the card management file 5. In addition, the balance area A2 of the card is read by the card reader/writer 4.
The advance payment amount is stored in . The customer can then use the card to pay for a fraction of the purchase price.

That is, the customer hands the card along with the purchased product to store n. The clerk first inserts a card into the card reader/writer 4, presses the card key 61, and then operates the department key 53 and the like to execute the registration process of the sales item. Then, when all products have been registered, the subtotal key 54 is pressed. Then, the fractional amount of the total amount in the word totalizer 72 is calculated for the fractional unit in the fractional unit memory 79, and the fractional amount is subtracted from the card balance of the card. Now, let's say that the fraction qt is [10 yen], and the customer's total amount is [10 yen].
103 yen], the fractional amount [3 yen] is calculated.

If the card balance before update is [10,000 yen], the card balance is updated to [9,997 yen]. However, the display shows the customer's payment amount [10,000 yen (10,103
-3)] will be displayed, and the total amount will be displayed on the receipt.
The fractional amount and payment amount are printed. After this, the clerk receives cash from the customer corresponding to the payment amount and presses the deposit/cash key 55 to complete the transaction. As a result, the 14th
A customer receipt R3 as shown in the figure is issued. Further, the contents of the remaining amount area A2 of the card are updated to the balance after the fractional amount has been reduced, and the current date is recorded in the last handling date area 3, and the card is returned to the customer. Further, the contents of the balance area B5 corresponding to the card number in the card management file 5 are updated in the same way, and the last date of handling is also changed to the current date.

In this way, when a customer makes a purchase and there is a fraction less than a fractional unit in the purchase price, the fractional amount is subtracted from the card balance of the card. Therefore, small change less than the fraction tIt is no longer used for giving and receiving money for payments.

When the card balance becomes less than a fractional unit, a message prompting the customer to add the advance payment as shown in FIG. 15 is printed on the customer receipt issued at that time.

The customer then hands the additional advance payment along with the card to the clerk. On the other hand, the store clerk will use Terminal 1 just as they did when issuing the card.
operate. Then, the added front bag amount is added to the card balance up to that point, and the card balance is increased. Therefore, the card balance can be increased by adding an advance payment each time the card balance decreases, so one card can be used for a long period of time unless the card is lost or damaged.

In addition, since the card management file 5 also manages the last date of handling by the card user, by checking the file 5, it becomes possible to accurately grasp the usage status of the card user.

On the other hand, if the customer loses or damages the card and wants to update it to a new card, store H first presses the update key 60 on the POS terminal 1.

Next, a new card that has already been issued to the customer is attached to the card reader/writer 4, and the card key 61 is pressed. Then, the card number and the like of the new card are stored in the card buffer 75.

Next, the clerk operates the number key 51 to enter the card number (13 digits) of the customer's old card. Then, the card number of the old card is stored in the work memory 76.

Next, the clerk enters his or her own cashier number and presses the signature key 58. Then, a card update confirmation message is sent to the store processor 2, and the prepaid amount area B3. The contents of the corresponding area corresponding to the old card number of the same file 5 are transferred to the last handling date area R4 and the balance area B5. Further, the contents of the balance area B5 corresponding to the new card number are sent back to the POS terminal 1, written on the new card as balance data of the new card, and used for subsequent payment of fractional amounts of shopping charges. Therefore, the balance of the old card that becomes unusable due to loss or damage is guaranteed as the balance of the new card, so even if the customer loses the card, there is no loss, and service quality can be improved. It can be measured.

Next, an embodiment in which the second invention of the present application is applied to the POS system shown in FIG. 1 will be described with reference to the drawings.

Note that the memory format of the card used in this embodiment is the same as that in the embodiment of the first invention of the present application, and
The explanation will be omitted using figures. Furthermore, since the schematic configurations of each POS terminal 1 and store processor 2 are the same as those in the embodiment of the first invention of the present application, a description thereof will be omitted with reference to FIGS. 4 to 7. However, in the second invention of the present application, since it is not necessary to input the amount of advance payment in advance, the deposit key 59 of the keyboard 39 and the deposit flag F3 of the RAM 33 in each POS terminal 1 can be omitted. Further, the card management file 5 provided in the store processor 2, as shown in FIG. 16, is the one in which the front bag amount area B3 of the card management file (FIG. 3) in the embodiment of the first invention of the present application is omitted. .

Accordingly, when the update key 60 is operated with the mode switch 37 selecting the "registration" mode, the CPU 31 of each POS terminal 1 executes the ninth The browser is configured to execute the card update process shown in the figure.

Further, the CPU 31 of each POS terminal 1 is program-controlled to execute the sales process shown in FIG. 17 by inputting a predetermined key while the "registration" mode is selected by the mode switch 37. That is,
When the key data of the card key 61 is taken in via the keyboard circuit 40, the card flag F1 is set, and the card data read by the card reader/writer 4 is written into the card buffer 75 via the card reader/writer control circuit 36. . Also, the card balance in the card data is written into the balance memory 80, and the next key input is awaited.

On the other hand, when the key data of the department key 53 is taken in via the keyboard circuit 40, the registration flag F2 is set, and the sales data of this department registered product is cumulatively processed in the department registration memory 71. In addition, the sales amount can be calculated using the 7
Add to 2.

Further, the department code and sales amount are displayed on the display 41, the printer 43 is driven to print them on the receipt, and the next key input is waited.

When the key data of the subtotal key 54 is taken in via the keyboard circuit 40, it is confirmed that the registration flag F2 is set. After that, the state of the card flag F1 is checked. If the card flag F1 has been reset, the customer does not process fractional amounts of shopping charges using a card, so normal subtotal key processing and closing key processing are executed.

When the card flag F1 is set, first, the card balance in the balance memory 80 is added to the total amount in the wealth meter 72, and the added amount is stored in the work memory 76 (calculating means). Next, the added amount in the work memory 76 is divided by the fraction unit in the fraction unit memory 79, and the remainder is stored as a fraction amount in the fraction amount memory 78 (fraction amount extraction means). Next, the fractional amount in the fractional amount memory 78 is subtracted from the added amount in the work memory 76, and the difference is stored in the payment amount memory 77 as the payment amount. Then, this payment amount is displayed on the display 41 (payment amount display means).

The printer 43 is also driven to print the total amount, card balance, and payment amount on a receipt.

Thereafter, the system waits for key input on the deposit/cash key 55.

When the deposit/total key 55 is input to instruct closing of the transaction by cash settlement, change is calculated and the change is displayed on the display 41. Next, the printer 43 is driven to print the deposited amount and change on a receipt. Furthermore, the fractional amount in the fractional amount memory 78 is printed on the receipt together with a predetermined message as the card writing amount, thereby issuing a customer receipt R5 shown in FIG. 19. Further, after updating the card balance in the card buffer 75 to the fractional amount in the fractional amount memory 78 and updating the last handled date to the current date stored in the clock circuit 34, the contents of the card buffer 75 are is transmitted to the card reader/writer 4 via the card reader/writer control circuit 36 and written into the card. Thereafter, the contents of the card buffer 75 are incorporated into a sales information message and transmitted to the store processor 2 via the inline line 3, and this processing is completed.

On the other hand, the CPU II of the store processor 2 is programmed to execute the process shown in FIG. 18 when the sales information message is input from each POS terminal 1 via the inline line 3. That is, it is determined whether or not card data exists in the first received sales information message. If it exists, the card number area B1 of the card management file 5 is searched using the card number included in the card data, and the contents of the balance area B5 corresponding to the card number are changed to the balance data in the card data. . Further, the contents of the handling last date area B4 corresponding to the card number are changed to the current date stored in the clock circuit 34 (last date setting means). Thereafter, various files in the disk memory 15 are updated based on the sales information in the message, and this process is completed. Note that if the card data is not included in the message, sales update processing is immediately performed and this processing is terminated.

In this embodiment configured as in 2, the store manager issues a card with the card number etc. recorded in advance to the customer who wishes to use the card, and also operates the keyboard 22 of the store processor 2 to Set the card number 1 name and address corresponding to the card management file 5. At this time, the card balance of the card is "0 yen". However,
The customer will be able to use the card to pay for the fractional amount of the purchase price.

That is, the customer hands the card along with the purchased product to the store clerk. The clerk first inserts a card into the card reader/writer 4, presses the card key 61, and then operates the department key 53 and the like to execute the registration process of the sales item. Then, when all products have been registered, the subtotal key 54 is pressed. Then, the balance of the card will be added to the total amount of reprimand.

Then, a fractional amount of the above-mentioned added amount is calculated for the fractional unit in the fractional unit memory 79, and this fractional amount is recorded as the card balance of the card. Further, the amount obtained by subtracting the fractional amount from the added amount is displayed on the display 41 as the payment amount.

Now, the fraction unit is [10 yen], and the total amount of the customer is [10
103 yen], and the card balance of the card held by the rebellious person is [8 yen], then the fractional amount [1 yen] is calculated. Then, the balance of the card is updated to [1 yen]. Also, the payment amount [10010 yen (10
103+8-3)] is displayed, and the total amount, fractional amount, and payment amount are printed on the receipt. After this, the clerk receives cash from the customer corresponding to the payment amount and presses the deposit/cash key 55 to complete the transaction. As a result, a customer receipt R5 as shown in FIG. 19 is issued. Further, the contents of the balance area B5 corresponding to the card number in the card management file 5 are updated in the same manner as the card, and the final handling date is also changed to the current date.

In this way, when a customer makes a purchase and there is a fraction less than a fractional unit in the purchase price, the fraction amount is carried over as the card balance until the next purchase. From the next time onwards, the card balance on the card will be added to the shopping price, and payment processing will be performed for the added amount. However, if there is a fractional amount in this added amount, the fractional amount will be updated as the card balance of the same card and carried over until the next purchase. Therefore, small change less than a fractional unit is no longer used for giving and receiving money for payments. Furthermore, since the balance on the card always changes by less than a fractional amount, one card can be used for a long period of time as long as the card is not lost or damaged.

In addition, since the card management file 5 also manages the card user's last transaction date, checking the file 5 makes it possible to grasp the usage status of the card user. Therefore, since the card stores the unpaid amount for the store, it is possible to take appropriate measures such as collection from customers who do not use the card for a long period of time.

On the other hand, when a customer loses or damages his or her card and updates it to a new card, the balance on the old card is reliably guaranteed as the balance on the new card, similar to the first invention of the present application. Even if a person loses their card, they will not suffer any loss, and service performance can be improved.

[Effects of the Invention] According to the present invention configured as described above, it is possible to provide a product sales data processing device that has the following effects. That is, according to the invention of claim 1, the card balance of a card that can be used for payment processing by subtracting the fractional amount incurred in payment of shopping charges from the card balance can be increased at any time by a simple key operation. The card can be used for a long time unless it is damaged or damaged, and the number of cards issued can be reduced when operating the system, thereby preventing high costs.

According to the invention of claim 2, the fractional amount generated in the payment of the shopping price is carried forward as a card balance until the next shopping, and the carried over amount is added to the next shopping price and the payment is made.
Moreover, if there is a fractional amount in the next payment, that fractional amount can be carried over as the card balance of the card, so that it can be used for a long time unless the card is lost or damaged. This makes it possible to reduce the number of cards issued and prevent high costs when operating the system.

According to the invention as claimed in claim 3, even if the card is lost or damaged, the balance of the card can be reliably guaranteed and recorded on a new card, so that serviceability can be improved and the use of the card can be improved. rate can be increased.

According to the invention of claim 4, since the last date of handling of a card user can be managed at the store opening, the usage status of the card can be clearly and accurately grasped, and appropriate measures can be taken according to the usage status. Can be done.
