The POS system 1 shown in FIG. 1 includes a plurality of product registration devices 10 (product registration device 10a, product registration device 10b, etc.), a plurality of payment devices 20 (payment device 20a, payment device 20b, etc.), and a store controller (store). Computers) 30, each of which is communicably connected via LAN 40. Hereinafter, when the individual product registration device 10a, the product registration device 10b, etc. are not particularly distinguished, they are simply referred to as the product registration device 10, and when the individual payment devices 20a, the payment device 20b, etc. are not particularly distinguished, they are simply referred to. It shall be simply referred to as a settlement device 20. A communication network other than LAN40 may be adopted.

In the POS system 1 according to the first embodiment (the same applies to the second embodiment), a system (point system) for giving points as a privilege to the customer is introduced.

(Outline of the point system of the first embodiment)
1. 1. Issue a point card (create a new one) to the desired customer. Specifically, as a point card, a storage area (for example, a magnetic area) and a printing area (for example, a coating area for a paint that reacts (colors) to a predetermined temperature; see a in FIG. 10A) are provided in the storage area. A rewrite card is issued in which information (for example, the number of points) can be rewritably stored and information can be rewritably printed in a print area. The point card may be issued by the product registration device 10 or by another device capable of issuing the point card (for example, a card reading device A, a card reading device B, etc., which will be described later). Good.
2. In the product registration device 10, when a customer points out a point card to a clerk (when handed over) at the time of registration of a purchased product (at the time of product registration), points are given among the products (purchased products) purchased by the customer. The number of points (the number of points this time) is calculated based on the total amount of the products (products subject to points), etc., and the number of points on the customer's point card is updated (stored in the storage area and printed in the print area). To do. For example, the number of points this time is added to the number of points accumulated last time for the customer to obtain the total number of points this time.
3. 3. In the product registration device 10, when a customer points out a point card and declares the use (consumption) of points at the time of product registration, the amount corresponding to the number of points used is deducted from the total amount of purchased products, and the relevant Update the number of points on the customer's point card (store in the storage area, print in the print area). For example, the number of points used is subtracted from the total number of points used by the customer last time to obtain the total number of points this time.
4. In the first embodiment, if it is necessary to add or cancel the purchased product at the time of payment after the number of points of the point card has been updated in the product registration device 10, the purchased product is added in the payment device 20. And cancel. If the number of points stored in the product registration device 10 increases or decreases as a result of the addition or cancellation of purchased products in the settlement device 20, the number of points stored in the point card in the product registration device 10 or the like is stored. Fix it. The same applies when the number of points used stored in the product registration device 10 increases or decreases as a result of the addition or cancellation of the purchased product in the settlement device 20.

Subsequently, each of the product registration device 10, the settlement device 20, and the store controller 30 will be described.

The product registration device 10 is a device operated by a clerk to perform registration processing of purchased products. For example, the product registration device 10 executes the registration process, generates registration process result information including the processing content of the registration process (product registration information regarding the purchased product of the customer), and designates the generated registration process result information by the clerk. It is transmitted to the settlement device 20.

More specifically, when the customer points out the point card at the time of product registration in the product registration device 10 (at least when the information stored in the point card is updated), the product registration device 10 of the customer A payment device 20 that generates registration processing result information including product registration information related to purchased products and point information (sometimes also referred to as service information) related to the customer's points, and the generated registration processing result information is designated by a clerk. Send to.

On the other hand, when the customer does not point out the point card at the time of product registration in the product registration device 10, the product registration device 10 includes registration processing result information (that is, point information) including product registration information regarding the purchased product of the customer. The registration process result information that does not include the above is generated, and the generated registration process result information is transmitted to the settlement device 20 designated by the clerk.

In addition, as an example of the case where the customer points out the point card at the time of product registration but does not update the information stored in the point card, the total amount of the points to be awarded (total amount to be awarded points) is the minimum unit to be granted (for example, 1). This is the case when the amount is less than the amount of points). In the product registration device 10, when the customer points out the point card at the time of product registration in the product registration device 10 but does not update the information stored in the point card, the point information (for example, the points are 0 points this time). The registration process result information including the point information) may be generated, or the registration process result information not including the point information may be generated.

Further, the product registration device 10 has a function of reading and writing information on the point card (rewrite card) (specifically, the card reading unit 112 shown in FIG. 2), and is stored in the point card pointed out by the customer. You can update the number of points you have.

For example, when the customer points out the point card at the time of product registration in the product registration device 10, the product registration device 10 calculates the number of points this time based on the total amount of the purchased products of the customer. Subsequently, the product registration device 10 stores the calculated number of points this time in the point card. Further, the product registration device 10 reads the accumulated points this time from the point card, stores the accumulated points this time read from the point card as the accumulated points last time in the point card, and calculates the accumulated points this time read from the point card. The number of points obtained by adding the number of points this time is stored in the point card as the total number of points this time.

Further, for example, when the customer points out the point card and declares the use of points at the time of product registration in the product registration device 10, the product registration device 10 reads the cumulative number of points this time from the point card and reads it from the point card this time. The accumulated points are stored in the point card as the previous accumulated points, and the points obtained by subtracting the used points from the accumulated points read from the point card this time are stored in the point card as the accumulated points this time.

Further, for example, when it is necessary to increase or decrease the number of points stored in the point card this time as a result of the registration process in the settlement device 20, the product registration device 10 uses the purchased product (that is, the purchased product after the registration process in the settlement device 20). , The number of points stored in the point card is updated (corrected) based on the total amount of the final purchased product). The details will be described later. The same applies to the case where it is necessary to increase or decrease the number of points used stored in the point card as a result of the registration process in the settlement device 20.

The settlement device 20 is a device that is mainly operated by the customer to perform the settlement processing of the purchased product. For example, the settlement device 20 executes the settlement process based on the registration process result information received from the product registration device 10, generates the settlement process result information including the processing content (settlement information) of the settlement process, and generates the settlement process. The result information is transmitted to the store controller 30.

The settlement device 20 can execute the registration process (addition / cancellation of the purchased product) of the purchased product in addition to the settlement process of the purchased product. In principle, the product registration device 10 performs the registration process of the purchased product by a clerk. For example, the settlement process in the settlement device 20 is basically executed by the customer himself, but if the customer requests the clerk to add or cancel the purchased product before the start of the settlement process (or during the process of the settlement process), the clerk Executes the registration process in the settlement device 20. The registration process in the settlement device 20 can be executed after performing a special operation (such as inputting a hidden command (including a password) or touching a predetermined position) known only to the clerk so that the customer cannot operate it freely. You may do so.

When the purchased product is added or canceled in the settlement device 20, at least a part of the purchased product at the end of the registration process in the settlement device 20 and the purchased product at the end of the registration process in the product registration device 10 Is different, so the number of points this time based on the total amount of purchased products at the end of the registration process in the settlement device 20 is the number of points this time based on the total amount of purchased products at the end of the registration process in the product registration device 10. May not match. That is, as a result of the registration process in the settlement device 20, it may be necessary to increase / decrease (correct) the number of points this time already stored in the point card in the product registration device 10.

The settlement device 20 issues (outputs) a recording medium (detailed receipt) at the end of the settlement process (when the deposit is equal to or greater than the total amount after pressing the settlement key). When the registration processing result information received from the product registration device 10 includes the point information (for example, when the point card is pointed out by the product registration device 10), the payment device 20 is stored in the point card. The contents (format, item) of the detailed receipt to be issued are different depending on the necessity of correction such as the number of points this time. If the registration process result information received from the product registration device 10 includes point information, it is necessary to correct the number of points, etc. this time by performing the purchase product registration process in the settlement device 20. This is the case when the number of points increases or decreases this time. On the other hand, when the registration processing result information received from the product registration device 10 includes the point information, it is not necessary to correct the number of points or the like this time because the purchase product is registered in the settlement device 20. This is the case where the number of points or the like does not increase or decrease this time, or the case where the purchase product registration process is not performed in the settlement device 20.

When it is not necessary to modify the number of points or the like this time, the settlement device 20 issues a detailed receipt including product registration information, settlement information, and point information. For example, the settlement device 20 includes product registration information (a in FIG. 10B), settlement information (b in FIG. 10B), and point information (FIG. 10B) as shown in FIG. 10B. Issue a detailed receipt containing c) and. If the registration processing result information received from the product registration device 10 does not include the point information, the number of points in the point information may not be printed (for example, "0" instead of the number of points. , "-" Or "*" may be printed, or the print position of the number of points may be left blank), and a detailed receipt containing product registration information and settlement information (that is, a detailed receipt not including point information) is issued. You may.

On the other hand, when it is necessary to correct the number of points or the like this time, the settlement device 20 issues a detailed receipt including product registration information, settlement information, point information, and point correction information. For example, the settlement device 20 includes product registration information (a in FIG. 11 (A)), settlement information (b in FIG. 11 (A)), and point information (FIG. 11 (A)) as shown in FIG. 11 (A). C), a detailed receipt (FIG. 11 (A)) including the point correction information (d in FIG. 11 (A)) and the point correction barcode (e in FIG. 11 (A)) are issued.

This time, 1 point will be awarded every time the total amount of points to be awarded (total amount of products subject to points) reaches 100 yen, and it is assumed that campaigns such as rainy days have not been implemented. Further, it is assumed that the product A is a product for which points are awarded and the price including tax is 216 yen (the price excluding consumption tax is 200 yen and the consumption tax is 16 yen). Product B is not a product for which points are awarded, and the price including tax is 420 yen (the price excluding consumption tax is 389 yen and the consumption tax is 31 yen). It is assumed that the product C is a product for which points are awarded and the price including tax is 100 yen (the price excluding consumption tax is 93 yen and the consumption tax is 7 yen).

Step S10: The purchased product is registered by scanning the scanner unit 104 or the like. After the execution of step S10, the process proceeds to step S11.
Step S11: It is determined whether or not the subtotal key has been pressed. If the subtotal key is pressed (YES), the process proceeds to step S12. On the other hand, if the subtotal key is not pressed (NO), the process returns to step S10. That is, the clerk presses the subtotal key after registering all the purchased products.

When giving points to the customer this time, the clerk receives the point card from the customer and inserts it into the card reading unit 112 before pressing the subtotal key. That is, when giving points to the customer this time, the clerk presses the subtotal key after inserting the customer's point card into the card reading unit 112.

FIG. 5A shows a product registration screen when a clerk (let's call it clerk T) registers the third purchased product (product C) of customer K. The product name and unit price of each registered purchased product are displayed near the middle left side (reference numeral a) of the product registration screen of FIG. 5 (A), and the product name and unit price of each registered purchased product are displayed at the upper part of the registered purchased product. The product name and unit price are displayed. A preset button for each product of seafood is arranged near the middle right side (reference numeral b) of the product registration screen of FIG. 5 (A), and the number of purchased points and the total price are displayed above the preset button. In addition, various buttons are arranged at the bottom of the product registration screen of FIG. 5A. Each button will be described as appropriate.

Step S12: It is determined whether or not the point card is being inserted (whether or not it exists at a position where reading and writing can be performed). For example, when a point card exists inside the card reading unit 112 (retention unit), the point card can be detected by transmitting a point card detection signal from the sensor of the card reading unit 112 to the CPU 101. It may be determined whether or not the point card is being inserted based on the presence or absence of the detection signal. If the point card is being inserted (YES), the process proceeds to step S13. On the other hand, if the point card is not being inserted (NO), the process proceeds to step S16.

Step S13: The stored contents (number of points, etc.) stored in the point card are updated based on the total amount of points to be granted. Also, the print content of the print area of the point card is updated. After the execution of step S13, the process proceeds to step S14.

Regarding step S13, for example, in the case of customer K described above, when the point card of customer K is being inserted, the process is as follows. First, the product registration device 10 refers to the point-giving target categories of the product A, the product B, and the product C, and the total amount of points to be given is 316 yen (the total amount of the products A and C which are the points-giving target products). The number of points (3 points) is calculated this time based on the total amount of points to be awarded (316 yen). Subsequently, the product registration device 10 stores the calculated number of points (3 points) this time in the storage area of the point card and prints it in the print area. In addition, the product registration device 10 reads the cumulative number of points (109 points) this time from the point card, and stores the cumulative number of points (109 points) read from the point card as the previous cumulative number of points in the storage area of the point card. The number of points (112 points) obtained by adding the number of points (3 points) this time to the total number of points (109 points) read from the point card after printing in the print area is stored in the storage area of the point card as the total number of points this time. And print the print area.

In step S13, the final purchase date and the expiration date are stored in the storage area of the point card and printed in the print area. The expiration date may not be stored in the storage area of the point card but may be printed only in the print area.

Step S14: The point card is ejected from the card reading unit 112. FIG. 10A is an example of the customer K's point card that is ejected when the customer K's point card is being inserted in the case of the customer K described above. The discharged point card will be returned to the customer. After the execution of step S14, the process proceeds to step S15.

Step S15: Generate registration process result information including product registration information and service information (point information). That is, the registration process result information including the service information is generated in addition to the product registration information. For example, in the case of the customer K described above, when the customer K presents the point card, the registration processing result information including the information of (a) to (d) of FIG. 6 (A) is generated. .. After the execution of step S15, the process proceeds to step S17.

Each piece of information (transaction number, cashier number, cashier, customer number, point card number) of FIG. 6A is basic information in the registration process (transaction). The “transaction number” in (a) of FIG. 6 (A) is a number that identifies each transaction. The "registration number" is a number that identifies the product registration device 10 that has undergone the registration process. The "cash register manager" is a number that identifies the clerk who performed the registration process. The "customer number" is a number that identifies the customer. The "point card number" is a number that identifies the point card (for example, a number stored in the point card). It should be noted that one of the customer number and the point card number may be managed without managing the customer number and the point card number separately. For example, in the case of an operation in which a plurality of point cards are not issued to the same customer, either the customer number or the point card number may be managed.

Each information (product, unit price (tax included), unit price (tax excluded), consumption tax, point grant target category) of FIG. 6 (A) (b) is product registration information in the registration process. (B) "Product" in FIG. 6 (A) is information (product code) that identifies each customer's purchased product. In addition to the product code, the product name may be included in the "product". The "unit price (tax included)" is the tax-included price of each customer's purchased product. The "unit price (excluding tax)" is the tax-excluded price of each customer's purchased product. "Consumption tax" is the consumption tax of the customer's individual purchased products. The “point award target category” is category information (for example, a flag or the like) indicating whether or not the product is a point award target product. In FIG. 6, the point award target category “1” indicates that the point award target product, and the point award target category “0” indicates that the point award target product is not.

Each information (total amount, taxable object (excluding tax), consumption tax) of FIG. 6A and FIG. 6C is product registration information in the registration process. The "total amount" in (c) of FIG. 6A is the total amount (tax included amount) of the purchased product of the customer. "Taxable (tax excluded)" is the total amount of goods purchased by the customer (tax excluded). The "consumption tax" is the consumption tax amount corresponding to the total amount (tax excluded amount) of the purchased products of the customer.

Each information (total amount of points to be granted, previous cumulative points, current points, current cumulative points) of FIG. 6A and (d) is service information in the registration process. The “total amount of points to be awarded” in (d) of FIG. 6 (A) is the total amount (tax included) of the products subject to points. The "previous cumulative points" is the cumulative number of points of the customer up to the previous time. "This time points" is the number of points that the customer earns this time. "This time accumulated points" is the total number of points after this processing (after adding this time points).

Step S16: Generate registration process result information including product registration information. That is, the registration process result information that does not include the service information is generated. For example, in the case of the customer K described above, when the customer K does not present the point card, the registration process result information (FIG. 6) including the information of (a) to (c) of FIG. 6 (A). 6 (Registration process result information) that does not include the information in (d) of (A) is generated. The item of "customer number" in (a) of FIG. 6 (A) may have no value or may not have the item itself. The same applies to the item of "point card number". After the execution of step S16, the process proceeds to step S17.

Step S17: The registration processing result information generated in step S15 or step S16 is stored in the RAM 103. After the execution of step S17, the process proceeds to step S18.
Step S18: The registration processing result information generated in step S15 or step S16 is transmitted to the settlement device 20 designated by the clerk. Then, this flowchart ends.

According to the flowchart of FIG. 4, when the product registration device 10 gives points this time (step S13), the product registration device 10 provides service information (point information) related to the points as shown in (d) of FIG. 6 (A). It is transmitted to the settlement device 20 (step S15, step S18).

It should be noted that each of the "payment machine 1 button" to "payment machine 3 button" at the bottom of FIG. 5A is a button for designating each payment device 20. For example, the "payment machine 1 button" corresponds to the payment device 20a, the "payment machine 2 button" corresponds to the payment device 20b, and the "payment machine 3 button" corresponds to the payment device 20c. For example, the clerk T designates the settlement device 20 by touching any of the "payment machine 1 button" to the "payment machine 3 button". Further, the registration processing result information may be directly transmitted from the product registration device 10 to the settlement device 20 designated by the clerk via the LAN 40, or the product registration device 10 may send the store controller 30 directly. It may be transmitted to the checkout device 20 via the store controller 30 and indirectly to the checkout device 20 designated by the clerk.

Further, the "point card forced ejection button" at the lower part of FIG. 5A is a button for forcibly ejecting the point card (point card existing in the retention portion) inserted in the card reading unit 112. The point card inserted into the card reading unit 112 is automatically ejected without touching the point card forced ejection button after giving points (step S13) (step S14), but the point card is ejected before giving points. If you want to eject, touch the point card forced ejection button. For example, when a customer who is asked to shop by an acquaintance mistakenly presents the customer's own point card to the clerk instead of the acquaintance's point card that should be pointed out to the clerk, so the point card currently being inserted is the customer's own point card. Or, when the customer has two or more point cards for himself and wants to add points to a point card different from the point card currently being inserted, he wants to take out the point card currently being inserted from the customer. When there is an offer, the clerk touches the point card forced ejection button.

The display mode (display position, display size, display color, etc.) of the point card forced ejection button may be different depending on whether the point card is inserted or not. For example, when the point card is inserted, the display mode may be more conspicuous than when the point card is not inserted. Further, when the point card is inserted, the point card forced ejection button may not be displayed.

Subsequently, the operation at the time of settlement in the settlement apparatus 20 will be described with reference to FIGS. 7 and 8 (A). Unless otherwise specified, the main body of the processing of each step in FIGS. 7 and 8 (A) is the settlement device 20 (CPU201). It is assumed that the product D is a product for which points are awarded and the price including tax is 756 yen (the price excluding consumption tax is 700 yen and the consumption tax is 56 yen).

Step S30: Receive the registration processing result information (see step S18 in FIG. 4) transmitted from the product registration device 10. The received registration processing result information is stored in, for example, RAM 203. After the execution of step S30, the process proceeds to step S32.
Step S32: Display the total amount. For example, the total amount is displayed together with the number of points purchased in the total column a of the settlement screen shown in FIG. 9A. For example, when the registration processing result information including the information of (a) to (d) of FIG. 6 (A) is received in step S30, the number of purchase points is 3 according to (b) of FIG. 6 (A). Since the points (product A, product B, product C) and the total amount is 736 yen according to (c) of FIG. 6 (A), the purchase points "3 pieces" are displayed in the total column a of FIG. 9 (A). , And the total amount of money "736 yen" is displayed. In the settlement screen shown in FIG. 9A, the amount of money and the message are displayed in the deposit column b, the change column c, and the message column d, but all of them are blank at the stage of processing in step S32. Is. After the execution of step S32, the process proceeds to step S33.

Step S33: It is determined whether or not there has been a registration change operation. That is, it is determined whether or not there is an operation that requires the change of the product registration information such as addition or cancellation of the purchased product. If there is a registration change operation (YES), the process proceeds to step S34. On the other hand, if there is no registration change operation (NO), the process proceeds to step S40. The registration change operation is based on the customer's request to the clerk to add or cancel the purchased product, and the clerk enters a special operation (such as inputting a hidden command (including a password) or touching a predetermined position, etc.). ) May be executed after the execution. The screen for registering the product in the settlement device 20 may be the same as the product registration screen displayed in the product registration device 10.

Step S34: The product registration information and the like are changed according to the registration change operation. That is, an operation of changing one product registered in the product registration device 10 to another product, an operation of additionally registering a product not registered in the product registration device 10, or registration in the product registration device 10. When there is an operation of canceling the registration of only one product, the product registration information is changed (for example, the registration processing result information stored in the RAM 203 is updated) according to each operation. For example, if there is an additional registration operation of adding the product D in step S33 after receiving the registration processing result information including the information of (a) to (d) of FIG. 6 (A) in step S30, In step S34, the product registration information and the service information are changed as shown in FIGS. 6A and 6B. That is, based on the additional registration of the product D, the product registration information shown in (b) of FIG. 6 (A) is changed as shown in (b) of FIG. 6 (B), and (c) of FIG. 6 (A). The product registration information shown in () is changed as shown in (c) of FIG. 6 (B), and the service information shown in (d) of FIG. 6 (A) is changed as shown in (d) of FIG. 6 (B). change. Since the total amount of points to be awarded before the additional registration of product D was 316 yen (total amount of product A and product C), the number of points was 3 points this time ((d) in FIG. 6 (A)). ), The total amount of points to be awarded after the additional registration of product D is 1072 yen (total amount of product A, product C, and product D), so the number of points this time is 10 points ((d) in FIG. 6 (B)). Is. After the execution of step S34, the process proceeds to step S35.

Step S35: Redisplay the total amount. For example, if there is an additional registration operation of adding the product D in step S33 after receiving the registration process result information including the information of (a) to (d) of FIG. 6 (A) in step S30, As shown in FIG. 9B, the total amount of money "1492 yen" is displayed together with the number of purchase points "4" in the total column a of the settlement screen. In the settlement screen shown in FIG. 9B, the amount and the message are displayed in the deposit column b, the change column c, and the message column d, but all of them are blank before the deposit is deposited. Is. After the execution of step S35, the process proceeds to step S40.

Step S40: It is determined whether or not the deposit has been deposited. That is, when the customer inserts cash into the slot of the change machine 210, it is determined whether or not the change machine 210 has notified the insertion amount (payment amount). If the deposit has been deposited (YES), the process proceeds to step S41. On the other hand, if there is no deposit (NO), the process proceeds to step S43.

Step S41: The deposit amount is stored (including renewal). That is, the total value of the input amount is stored. After the execution of step S41, the process proceeds to step S42.
Step S42: Display (including redisplay) the deposit amount. That is, the total value of the input amount is displayed to the customer. After the execution of step S42, the process proceeds to step S43.

Step S43: It is determined whether or not the settlement key has been pressed (touched). That is, it is determined whether or not there is an instruction from the customer to settle the payment. If the settlement key is pressed (YES), the process proceeds to step S44. On the other hand, if the settlement key is not pressed (NO), the process returns to step S33. That is, the customer can offer the clerk to add or cancel the purchased product or insert cash into the slot of the change machine 210 until the checkout key is pressed.

Step S44: It is determined whether or not the deposit is insufficient. That is, it is determined whether or not the deposit amount stored in step S41 is less than the total amount of the purchased products. If there is no registration change operation (step S33), the total amount received (for example, the total amount in (c) of FIG. 6A) is the total amount of the purchased products. When there is a registration change operation, the total amount after the change (update) (for example, the total amount in (c) of FIG. 6B) is the total amount of the purchased products. If the deposit is insufficient (YES), the process returns to step S33. On the other hand, if the deposit is not insufficient (NO), the process proceeds to step S45.

Step S45: It is determined whether or not the product registration information has been changed by the change operation. For example, the product registration information included in the registration processing result information received in step S30 is stored in two different storage areas, and in step S34, the product registration information stored in one storage area is not changed and the other is stored. The product registration information stored in the storage area may be changed, and in step S45, it may be determined whether or not the product registration information stored in both storage areas has been changed depending on whether or not they match. If the product registration information has been changed (YES), the process proceeds to step S46. On the other hand, if the product registration information has not been changed (NO), the process proceeds to step S50 of FIG. 8 (A).

Step S46: It is determined whether or not the points have increased or decreased this time due to the change of the product registration information. If the points increase or decrease this time (YES), the process proceeds to step S47. On the other hand, if the points do not increase or decrease this time (NO), the process proceeds to step S50 in FIG. 8 (A). If the additionally registered or canceled purchased product is not a point-granting product, or if the changed purchased products (the purchased product before the change and the purchased product after the change) are not the points-granting products, the product is registered. Even if the information is changed, the points will not increase or decrease this time. In addition, even if the additionally registered or canceled purchased product is a point-granting product, the total amount does not fluctuate much, or even if the changed purchased product is a point-giving target product, the difference in unit price between the changed purchased products. If the number is small, the points may not increase or decrease this time even if the product registration information is changed.

Step S47: It is determined whether or not the current point before the change (the current point calculated in the registration process in the product registration device 10) was 0 point. If the current point before the change is 0 point (YES), the process proceeds to step S48. That is, the points were not generated this time at the stage of product registration in the product registration device 10, but if points are generated this time due to the addition of purchased products in the settlement device 20, the process proceeds to step S48. On the other hand, if the current point before the change is not 0 point (NO), the process proceeds to step S60 in FIG. 8 (A). That is, the points were generated this time at the stage of product registration in the product registration device 10, but when the points increase or decrease this time due to the addition of purchased products in the settlement device 20 (including the case where the points become 0 points). The process proceeds to step S60 of FIG. 8A.

Step S48: Display a message confirming the necessity of points this time. For example, as shown in FIG. 8B, the number of generated points (reference numeral a), a message indicating that the generated points can be acquired (reference numeral b), and a message confirming the necessity of the generated points (reference numeral c). , And a confirmation screen with a "Yes (necessary) button" to indicate that it is necessary and a "No (unnecessary) button" to indicate that it is not necessary, while displaying the precautions (code d). It may be displayed. The confirmation screen is deleted by touching either the "Yes (necessary) button" or the "No (unnecessary) button". For example, a customer purchases one product B (tax-included price of 420 yen) that is not a point-granting product in the product registration device 10 (total amount of one point-giving target is 0 yen), and the settlement device 20. When one product A (tax-included price 216 yen), which is a point-granting product, is added (total amount of points for a total of 2 points is 216 yen), the back of the confirmation screen as shown in Fig. 8 (B). On the settlement screen (total column) on the side, the number of points purchased "2" and the total amount "636 yen" are displayed. After the execution of step S48, the process proceeds to step S49.

Step S49: It is determined whether or not there is an operation indicating that points are required this time. If there is an operation to the effect that it is necessary (YES), for example, if the “Yes (necessary) button” is touched on the confirmation screen shown in FIG. 8 (B), the process proceeds to step S60 in FIG. On the other hand, if there is no operation to the effect that it is necessary (NO), for example, if the "No (unnecessary) button" is touched on the confirmation screen shown in FIG. 8 (B), the process proceeds to step S50 in FIG.

Step S50: Calculate the amount of change. After the execution of step S50, the process proceeds to step S51.
Step S51: If there is change, the change is discharged from the discharge port of the change machine 210. After the execution of step S51, the process proceeds to step S52.

Step S52: A message indicating that a detailed receipt will be issued is displayed (if there is change, a message indicating that there is change is also displayed). After the execution of step S52, the process proceeds to step S53.

9 (A) is an example of the settlement screen displayed in step S52 when the registration process result information including the information of (a) to (d) of FIG. 6 (A) is received in step S30 of FIG. 7. Is. That is, in the case of the customer K described above, if the registration processing result information transmitted from the product registration device 10 is received when the customer K is presenting the point card, and the points are not increased or decreased this time, The settlement screen as shown in FIG. 9A is displayed.

The number of purchase points "3" and the total amount "736 yen" in the total column a of FIG. 9 (A) are the number of products (product A, product B, product C) shown in (b) of FIG. 6 (A). And the total amount of money "736" shown in (c) of FIG. 6 (A). The amount "750 yen" in the deposit column b of FIG. 9A represents the deposit amount (that is, the input amount of the customer K) stored in step S41 of FIG. The amount of money "14 yen" in the change column c of FIG. 9A represents the change amount calculated in step S50. “Please receive the change and receipt” in the message field d of FIG. 9A is the message displayed in step S52.

Step S53: Print and issue a detailed receipt. Specifically, a detailed receipt including product registration information, settlement information, and point information is printed and issued. After the execution of step S53, the process proceeds to step S64.

FIG. 10B is a specification printed and issued in step S53 when the registration processing result information including the information of FIGS. 6A to 6D is received in step S30 of FIG. This is an example of a receipt. That is, when the registration processing result information including the information of (a) to (d) of FIG. 6 (A) is received in step S30 and the points are not increased or decreased this time in the settlement device 20, FIG. A detailed receipt as shown in 10 (B) is printed and issued.

Product registration information based on (b) and (c) of FIG. 6 (A) is printed on a of FIG. 10 (B). In b of FIG. 10 (B), the total amount of money in (c) of FIG. 6 (A), the deposit amount stored in step S41 of FIG. 7, and the change calculated in step S50 of FIG. 8 (A) are shown. Settlement information based on the amount is printed. Point information (service information) based on (d) of FIG. 6 (A) is printed on c of FIG. 10 (B).

Step S60: Calculate the amount of change. After the execution of step S50, the process proceeds to step S61.
Step S61: If there is change, the change is discharged from the discharge port of the change machine 210. After the execution of step S61, the process proceeds to step S62.

Step S62: Display a message that a detailed receipt with point correction information is issued (if there is change, a message that there is change is also displayed). After the execution of step S62, the process proceeds to step S63.

9 (B) is an example of the settlement screen displayed in step S62 when the registration process result information including the information of (a) to (d) of FIG. 6 (A) is received in step S30 of FIG. 7. Is. That is, in the case of the customer K described above, when the customer K is presenting the point card, the registration processing result information transmitted from the product registration device 10 is received, and the product D is additionally registered. When there is an increase, a settlement screen as shown in FIG. 9B is displayed.

The purchase points "4 pieces" and the total amount "1492 yen" in the total column a of FIG. 9 (B) are the products (product A, product B, product C, product D) shown in (b) of FIG. 6 (B). ) And the total amount “1492” shown in (c) of FIG. 6 (B). The amount "1502 yen" in the deposit column b of FIG. 9B represents the deposit amount (that is, the input amount of the customer K) stored in step S41 of FIG. The amount of money "10 yen" in the change column c of FIG. 9B represents the change amount calculated in step S60. "Please receive the change and receipt (with the point correction code) in the message field d of FIG. 9B. * Points need to be corrected by the registration device." Is the message displayed in step S62.

It should be noted that, although points were not generated this time at the stage of product registration in the product registration device 10, points were generated this time due to the addition of purchased products in the settlement device 20, and an operation indicating that points are required this time. If there is (in the case of step S49 (YES)), points that were not originally granted will be newly granted this time. Therefore, it is not a message to the effect that the points were originally given this time as shown in the message field d of FIG. 9 (B), but is originally given as shown in the message field d of FIG. 9 (C). You may display a message that points have been awarded this time. That is, in FIG. 9C, it is not "correction" but "grant".

Step S63: Print and issue a detailed receipt with point correction information. Specifically, a detailed receipt including product registration information, settlement information, point information, point correction information, and point correction barcode is printed and issued. After the execution of step S63, the process proceeds to step S64.

11 (A) shows the details printed and issued in step S63 when the registration process result information including the information of (a) to (d) of FIG. 6 (A) is received in step S30 of FIG. This is an example of a receipt. That is, in step S30, the points are increased this time by receiving the registration processing result information including the information of (a) to (d) of FIG. 6 (A) and additionally registering the product D in the settlement device 20. If so, a detailed receipt as shown in FIG. 11A is printed and issued.

Product registration information based on (b) and (c) of FIG. 6 (B) is printed on a of FIG. 11 (A). In b of FIG. 11 (A), the total amount of money in (c) of FIG. 6 (B), the deposit amount stored in step S41 of FIG. 7, and the change calculated in step S60 of FIG. 8 (A) are shown. Settlement information based on the amount is printed. Point information (service information) based on (d) of FIG. 6 (B) is printed on c of FIG. 11 (A). Point correction information including "reflected points" and "unreflected points (correction required points)" is printed on d in FIG. 11A. "Reflected points" is the number of points already reflected on the point card. The three "reflected points" of d in FIG. 11 (A) are based on the value "3" of the current point in (d) of FIG. 6 (A). "Unreflected points" is the number of points this time that have not yet been reflected on the point card. The seven points of the "unreflected points" in d of FIG. 11 (A) are the values of the current points in (d) of FIG. 6 (B) to the values of the current points in (d) of FIG. 6 (A). It is obtained by subtracting "3". A point correction barcode is printed on e in FIG. 11A. The point correction barcode is a barcode that encodes point correction information (at least the number of "unreflected points").

Step S64: Generate settlement processing result information including settlement information. For example, basic information (for example, basic information in which a number for identifying a settlement device 20 that has undergone settlement processing is added to the basic information shown in (a) of FIG. 6 (A)) and product registration information (for example, FIG. 6 (A)). ) (B) (c) and (b) (c) of FIG. 6 (B) and the settlement information (for example, b of FIG. 10 (B) or b of FIG. 11 (A)). Generates settlement processing result information including the indicated total amount, deposit amount, change amount, etc.). The generated settlement processing result information may be stored in the RAM 203. After the execution of step S64, the process proceeds to step S65.
Step S65: The settlement processing result information generated in step S64 is transmitted to the store controller 30. Then, this flowchart ends.

Subsequently, the operation at the time of point correction in the product registration device 10 will be described with reference to FIG. Unless otherwise specified, the main body of the processing of each step in FIG. 12 is the product registration device 10 (CPU101).

Step S70: Acquire point correction information. Specifically, the point correction information is acquired by having the scanner unit 104 read the point correction barcode printed on the detail receipt with the point correction information. For example, in the case of the customer K described above, the point correction information is read by the scanner unit 104 to read the point correction barcode printed on the detailed receipt with the point correction information of the customer K shown in FIG. 11 (A). (Information indicating that the unreflected points are 7 points, etc.) is acquired. After the execution of step S70, the process proceeds to step S71.
Step S71: The point correction information is stored. For example, the point correction information is stored in the RAM 103. After the execution of step S71, the process proceeds to step S72.

Step S72: It is determined whether or not the point card is being inserted. For example, in the case of customer K described above, it is determined whether or not the point card of customer K shown in FIG. 10A is being inserted. If the point card is being inserted (YES), the process proceeds to step S73. On the other hand, if the point card is not being inserted (NO), the process proceeds to step S83.

Step S73: Display a message prompting the insertion of the point card. For example, as shown in FIG. 5B, a message screen displaying the reason for requesting the insertion of the point card (reference numeral a) and the message for requesting the insertion of the point card (reference numeral b) is displayed. After the execution of step S73, the process proceeds to step S74.

Step S74: It is determined whether or not the point card is being inserted. If the point card is being inserted (YES), the process proceeds to step S75. On the other hand, if the point card is not being inserted (NO), the process returns to step S74.
Step S75: The message displayed in step S73 is deleted. After the execution of step S75, the process proceeds to step S83.

Step S83: The stored contents stored in the point card are updated based on the point correction information. Also, the print content of the print area of the point card is updated. After the execution of step S83, the process proceeds to step S84.

Regarding step S83, for example, in the case of customer K, it is as follows. The product registration device 10 reads the current number of points (3 points) and the current cumulative number of points (112 points) from the point card, and adds the unreflected points (7 points) to the read current number of points (3 points). (10 points) is stored in the storage area of the point card as a new number of points this time, printed in the print area, and the total number of points read this time (112 points) plus unreflected points (7 points) is added to the number of points (7 points). 119 points) is stored in the storage area of the point card as a new cumulative number of points this time, and is printed in the print area.

Step S84: The point card is ejected. As a result, the point card as shown in FIG. 11B is ejected. Then, this flowchart ends. The discharged point card will be returned to the customer. The content of FIG. 11B is the content of FIG. 10B plus unreflected points (7 points) generated by the additional registration of the product D in the settlement device 20. If the settlement device 20 cancels the purchased product, the unreflected points may become a negative value.

As described above, according to the POS system 1 according to the first embodiment, after the number of points of the point card has been updated in the product registration device 10, the product is changed (addition or cancellation of the purchased product) in the payment device 20. In that case, a detailed receipt with point correction information is issued by the settlement device 20, and the detailed receipt with the point correction information is read by the product registration device 10, so that the points generated by the change of the product in the settlement device 20 The increase / decrease in the number can be reflected in the point card.

(Second Embodiment)
Hereinafter, the POS system according to the second embodiment will be described. The network configuration, the product registration device 10, the checkout device 20, and the store controller 30 in the second embodiment are the same as those in the first embodiment. Hereinafter, a part or all of the parts common to the first embodiment such as the above-mentioned network configuration will be omitted, and the second embodiment will be described focusing on the parts different from the first embodiment.

(Outline of the point system of the second embodiment)
1. 1. Similar to the first embodiment, a point card (rewrite card) is issued to a desired customer.
2. Similar to the first embodiment, when the customer points out the point card at the time of product registration, the number of points is calculated this time and the number of points of the customer's point card is updated.
3. 3. Similar to the first embodiment, when the customer points out the point card and declares the use (consumption) of the points at the time of product registration, the amount corresponding to the number of points used is deducted from the total amount of the purchased products, and the amount is reduced. Update the number of points on the customer's point card.
4. In the second embodiment, if it is necessary to add or cancel the purchased product at the time of payment after the number of points of the point card has been updated in the product registration device 10, the transaction is recalled to the product registration device 10. , The product registration device 10 adds or cancels purchased products. The product registration device 10 updates (recalls) the number of points on the customer's point card based on the final total amount of points to be awarded after adding or canceling purchased products and the declared final number of points used. Since it has already been updated once before, it can be said to be re-updated).

Subsequently, an operation example of the POS system according to the second embodiment will be described with reference to FIGS. 13 to 19. FIG. 13 is a flowchart showing an example of the operation of the settlement device 20. FIG. 14 is a flowchart showing an example of the operation of the product registration device 10 when the registration is changed (addition or cancellation of purchased products). FIG. 15 is a continuation of the flowchart of FIG.
That is, FIGS. 14 and 15 are flowcharts showing an example of the operation of the product registration device 10 after recall. The operation of the product registration device 10 at the time of product registration in the second embodiment is the same as the operation of the product registration device 10 at the time of product registration in the first embodiment (see FIG. 4).

16 to 18 are examples of screens displayed on the product registration device 10. Specifically, FIG. 16A is an example of a registration processing screen before product registration. FIG. 16B is an example of the unsettled list screen. FIG. 17A is an example of a product registration screen displayed by recall. FIG. 17B is an example of a message screen prompting the insertion of a point card. FIG. 18A is an example of a message screen prompting the insertion of an appropriate point card. FIG. 18B is an example of the product registration screen when the product D is additionally registered. FIG. 19 is an example of a point card and a detailed receipt. Specifically, FIG. 19A is an example of a point card returned to the customer after the registration process (addition / cancellation of purchased products) in the product registration device 10 is completed. FIG. 19B is an example of a detailed receipt issued after the settlement process is completed in the settlement device 20 when the registration process (addition or cancellation of the purchased product) is performed in the product registration device 10.

First, the operation at the time of settlement in the settlement apparatus 20 will be described with reference to FIG. Unless otherwise specified, the main body of the processing of each step in FIG. 13 is the settlement device 20 (CPU201).

Step S130: Similar to step S30 of FIG. 7 of the first embodiment, the registration processing result information (see step S18 of FIG. 4) transmitted from the product registration device 10 is received. The received registration processing result information is stored in, for example, RAM 203. After the execution of step S130, the process proceeds to step S131.

Step S131: If the settlement process of the transaction is suspended, the hold of the settlement process is released. After the execution of step S131, the process proceeds to step S132.

In connection with step S131, the suspension of processing of a certain transaction will be described. The processing of a transaction is suspended when the progress of the processing of the transaction is restricted (prohibited). In other words, the fact that the settlement process of a certain transaction is suspended means that the progress of the settlement process of the transaction is restricted. When the settlement process of a certain transaction is suspended, the RAM 203 stores the information that the settlement process is suspended for the transaction, and whether or not the settlement process of the transaction is suspended is the information that the settlement process is suspended for the transaction. Is determined based on whether or not is stored in the RAM 203, and if it is determined that the settlement process of a certain transaction is suspended, the progress of the settlement process of the transaction may be restricted. On the other hand, when releasing the hold of the settlement process of a certain transaction, the information stored in the RAM 203 to the effect that the settlement process is held may be deleted.

Therefore, in step S131, when it is determined that the information to suspend the settlement process for the transaction is stored in the RAM 203, the information to suspend the settlement process for the transaction stored in the RAM 203 is deleted. do it. As an example, a hold transaction storage area is provided in a predetermined area of the RAM 203, and when the settlement process of a certain transaction is held, the transaction number of the transaction is stored in the hold transaction storage area. In step S131, the hold transaction storage area is used. If it is determined that the transaction number of the transaction is stored, the transaction number of the transaction stored in the reserved transaction storage area may be deleted.
..

Step S132: Similar to step S32 of FIG. 7 of the first embodiment, the total amount is displayed. After the execution of step S132, the process proceeds to step S136.

Step S136: It is determined whether or not there is a hold operation for the settlement process. That is, it is determined whether or not there is an operation to suspend the settlement process of the transaction. If there is a hold operation for the settlement process (YES), the process proceeds to step S137. On the other hand, if there is no hold operation for the settlement process (NO), the process proceeds to step S140. In addition, the hold operation of the settlement process is based on the customer's request to the clerk to add or cancel the purchased product, and the clerk inputs a special operation (input of a hidden command (including a password, etc.) or touches a predetermined position). Etc.) may be executed after the execution.

Step S137: Hold the settlement process of the transaction in response to the hold operation of the settlement process. For example, the transaction number of the transaction may be stored in the reserved transaction storage area described above. After the execution of step S137, the process proceeds to step S138.

Step S138: Send a recall request. The recall request is a request for returning the processing of the transaction to the product registration device 10 that is the transmission source of the registration processing result information received in step S130. That is, in order to return the processing of the transaction, a recall request is transmitted to the product registration device 10 that is the transmission source of the registration processing result information received in step S130. The recall request may be directly transmitted from the settlement device 20 to the product registration device 10 of the transmission source via the LAN 40, or may be transmitted from the settlement device 20 to the store controller 30. It may be indirectly transmitted to the product registration device 10 of the transmission source via the store controller 30. Then, this flowchart ends.

When the product registration device 10 receives the recall request (see step S138 in FIG. 13) transmitted from a certain settlement device 20, it is necessary to recall the processing from the settlement device 20 (or). It simply notifies that the recall request has been received from the settlement device 20). For example, when the product registration device 10 receives the recall request transmitted from the payment device 20a, as shown in FIG. 16A, the product registration device 10 has a "payment machine 1 button" above the "payment machine 1 button" corresponding to the payment device 20a. By displaying the icon (reference numeral a) stating "Call back required", the store clerk may be notified that the processing from the settlement device 20a needs to be recalled.

Further, in the example shown in FIG. 16A, by displaying an icon (reference numeral b) marked “insufficient change” at the upper part of the “payment machine 2 button” corresponding to the payment device 20b, the clerk is notified. The settlement device 20a notifies that the change is insufficient. Further, by displaying the icon (reference numeral c) marked "offline" on the upper part of the "payment machine 3 button" corresponding to the payment device 20c, the clerk can communicate with the payment device 20c offline (for example,). The power of the settlement device 20c is turned off, etc.).

Step S140: Similar to step S40 of FIG. 7 of the first embodiment, it is determined whether or not the deposit has been deposited. If the deposit has been deposited (YES), the process proceeds to step S141. On the other hand, if there is no deposit (NO), the process proceeds to step S143.

Step S141: As in step S41 of FIG. 7 of the first embodiment, the deposit amount is stored (including renewal). After the execution of step S141, the process proceeds to step S142.
Step S142: Similar to step S42 of FIG. 7 of the first embodiment, the deposit amount is displayed (including redisplay). After the execution of step S142, the process proceeds to step S143.

Step S143: Similar to step S43 of FIG. 7 of the first embodiment, it is determined whether or not the settlement key has been pressed (touched). If the settlement key is pressed (YES), the process proceeds to step S144. On the other hand, if the settlement key is not pressed (NO), the process returns to step S136. That is, the customer can offer the clerk to add or cancel the purchased product or insert cash into the slot of the change machine 210 until the checkout key is pressed.

Step S144: Similar to step S44 of FIG. 7 of the first embodiment, it is determined whether or not the deposit is insufficient. If the deposit is insufficient (YES), the process returns to step S136. On the other hand, if the deposit is not insufficient (NO), the process proceeds to step S150.

Step S150: The change amount is calculated in the same manner as in step S50 of FIG. 8 of the first embodiment. After the execution of step S150, the process proceeds to step S151.
Step S151: Similar to step S51 of FIG. 8 of the first embodiment, when there is change, the change is discharged from the discharge port of the change machine 210. After the execution of step S151, the process proceeds to step S152.

Step S152: Similar to step S51 of FIG. 8 of the first embodiment, a message indicating that a detailed receipt is issued is displayed (when there is change, a message indicating that there is change is also displayed). That is, when the registration process result information including the information of (a) to (d) of FIG. 6 (A) is received in step S130, for example, the settlement screen as shown in FIG. 9 (A) is displayed. To do. After the execution of step S152, the process proceeds to step S153.

Step S153: Similar to step S53 of FIG. 8 of the first embodiment, the detailed receipt is printed and issued. That is, when the registration process result information including the information of (a) to (d) of FIG. 6 (A) is received in step S130, the detailed receipt as shown in FIG. 10 (B) is printed. ,publish. After the execution of step S153, the process proceeds to step S164.

Step S164: Similar to step S64 of FIG. 8 of the first embodiment, the settlement processing result information including the settlement information is generated. The generated settlement processing result information may be stored in the RAM 203. After the execution of step S164, the process proceeds to step S165.
Step S165: The settlement processing result information generated in step S164 is transmitted to the store controller 30. Then, this flowchart ends.

Subsequently, the operation when the registration is changed (addition or cancellation of the purchased product) in the product registration device 10 will be described with reference to FIGS. 14 and 15. Unless otherwise specified, the main body of the processing of each step in FIGS. 14 and 15 is the product registration device 10 (CPU101). The product registration device 10 has received the recall request (see step S138 in FIG. 13) transmitted from the settlement device 20a, and at the start of the flowchart shown in FIG. 14, as shown in FIG. 16 (A). It is assumed that the icon marked "Call back required" is displayed above the "Settlement machine 1 button" corresponding to the settlement device 20a.

Step S270: Recall the transaction. That is, the transaction in the state where the registration process is completed but the settlement process is not completed (unsettled transaction) is changed to the state before the completion of the registration process (for example, the state before the subtotal key is pressed). After the execution of step S270, the process proceeds to step S271.

With respect to step S270, the flow until the product registration device 10 receives the recall request transmitted from the settlement device 20a and performs the recall is shown in FIGS. 16 (A), 16 (B) and 17 (A). I will explain.

As shown in FIG. 16A, the clerk who confirmed that the icon marked "Call back required" is displayed at the top of the "Payment machine 1 button" on the registration processing screen displays the unpaid list screen. Touch the "Unpaid One Button" to do. The unsettled list screen is a screen for displaying a list of unsettled transactions. When the "one unpaid button" is touched, the product registration device 10 displays the unpaid list screen as shown in FIG. 16B.

In the list display area (reference numeral a) on the left side of the unsettled list screen of FIG. 16 (B), three unsettled transactions that have been registered in the product registration device 10 are listed. For example, the newest unsettled transaction (unsettled transaction with transaction number "1235") is displayed in association with the number "1", and the second newest unsettled transaction (unsettled transaction with transaction number "1235") associated with the number "2". The unsettled transaction with transaction number "1234") is displayed, and the oldest unsettled transaction (unsettled transaction with transaction number "1233") is displayed in association with the number "3". Further, at the right end of each unsettled transaction, information about the destination settlement device 20 (the settlement device 20 that executes the settlement processing of each unsettled transaction) is displayed. Further, in the list display area, individual unsettled transactions can be selected by touching the display area of each unsettled transaction. It also highlights the number of the unsettled transactions that are currently selected so that you know which unsettled transactions are selected. In the case of FIG. 16B, the number “2” is highlighted so that it can be seen that the unsettled transaction of the number “2” is selected. In the unsettled display screen that is displayed first after the "unsettled one button" is touched, one unsettled transaction (for example, the unsettled transaction with the number "1") may be initially selected. When the recall request is received, the unsettled transaction related to the recall request may be initially selected. In the transaction content display area (reference numeral b) on the right side of the unsettled list screen of FIG. 16 (B), details of the unsettled transactions selected in the list display area (information about purchased products, various points, destinations, etc.) ) Is displayed.

As shown in FIG. 16B, when the "recall button" is touched while the unsettled process of the number "2" is selected on the unsettled list screen, the product registration device 10 does not have the number "2". Recall the settlement transaction. Specifically, the registration processing screen as shown in FIG. 17 (A) of FIG. 17 (A) is displayed instead of the unsettled list screen of FIG. 16 (B). On the registration processing screen shown in FIG. 17A, purchased products similar to the contents of the registration processing screen shown in FIG. 5A are displayed. Further, in the registration processing screen shown in FIG. 17 (A), the icon marked "Recalling" is replaced with the icon marked "Recall required", which corresponds to the "Payment machine 1" corresponding to the payment device 20a. It is displayed at the top of the "button". That is, the store clerk is notified that the content (purchased product, etc.) currently displayed on the registration processing screen is the content of the processing recalled from the settlement device 20a.

Step S271: It is determined whether or not the point card was used in the recalled transaction. For example, the point card is used in a transaction recalled depending on whether or not the service information is included in the registration processing result information (registration processing result information stored in step S17 of FIG. 4) of the transaction stored in the RAM 103. You may judge whether or not it is. That is, if the service information was included in the registration processing result information of the transaction, it was determined that the point card was used in the recalled transaction, and the service information was not included in the registration processing result information of the transaction. In some cases, it may be determined that the point card was not used in the recalled transaction. If the point card has been used (YES), the process proceeds to step S272. On the other hand, if the point card is not used (NO), the process proceeds to step S310 of FIG.

Step S272: Similar to step S72 of FIG. 12 of the first embodiment, it is determined whether or not the point card is being inserted. If the point card is being inserted (YES), the process proceeds to step S280. On the other hand, if the point card is not being inserted (NO), the process proceeds to step S273.

Step S273: Similar to step S73 of FIG. 12 of the first embodiment, a message prompting the insertion of the point card is displayed. For example, as shown in FIG. 17B, a message screen displaying the reason for requesting the insertion of the point card (reference numeral a) and the message for requesting the insertion of the point card (reference numeral b) is displayed. After the execution of step S73, the process proceeds to step S74.

Step S274: Similar to step S74 of FIG. 12 of the first embodiment, it is determined whether or not the point card is being inserted. If the point card is being inserted (YES), the process proceeds to step S275. On the other hand, if the point card is not being inserted (NO), the process returns to step S274.
Step S275: Similar to step S75 in FIG. 12 of the first embodiment, the message displayed in step S273 is deleted. After the execution of step S275, the process proceeds to step S280.

Step S280: It is determined whether or not the point card being inserted is the point card used in the recalled transaction. For example, the point card number of the point card being inserted matches the point card number stored in the registration processing result information of the transaction (registration processing result information stored in step S17 of FIG. 4) stored in the RAM 103. It may be determined whether or not the point card being inserted is the point card used in the recalled transaction depending on whether or not the point card is inserted. In other words, if the point card numbers match, it is determined that the point card being inserted is the point card used in the recalled transaction, and if the point card numbers do not match, it is being inserted. It may be determined that the point card is not the point card used in the recalled transaction. If the point card being inserted is the point card used in the recalled transaction (YES), the process proceeds to step S310 of FIG. On the other hand, if the point card being inserted is not the point card used in the recalled transaction (NO), the process proceeds to step S281.

Step S281: Display a message that the point card was not used in the recalled transaction. For example, as shown in FIG. 18A, a message indicating that a point card different from the point card used earlier (reference numeral a) has been inserted and a message requesting the insertion of the point card used earlier (reference numeral b) are displayed. At the same time, a confirmation screen may be displayed in which an "OK button" is arranged to indicate that the point card used earlier is to be inserted. After the execution of step S281, the process proceeds to step S282.

Step S282: It is determined whether or not there is an operation indicating that the user has agreed to insert the point card used earlier. If there is an operation to the effect that it is understood (YES), for example, if the "OK button" is touched on the confirmation screen shown in FIG. 18 (A), the process proceeds to step S283. On the other hand, if there is no operation to the effect that it is necessary (NO), for example, if the "OK button" is not touched on the confirmation screen shown in FIG. 18 (A), the process returns to step S282.

Step S283: The message displayed in step S281 is deleted. After the execution of step S283, the process proceeds to step S284.
Step S284: The point card is ejected. As a result, a point card different from the point card used in the recalled transaction (the erroneously inserted point card is ejected. After the execution of step S283, the process returns to step S272.

Step S310: The purchased product is changed (added or canceled) by scanning the scanner unit 104 or the like. After the execution of step S310, the process proceeds to step S311. If there is no change or the like, the process proceeds to step S311 without performing the process of step S310.
Step S311: Similar to step S11 of FIG. 4 of the first embodiment, it is determined whether or not the subtotal key is pressed. If the subtotal key is pressed (YES), the process proceeds to step S312. On the other hand, if the subtotal key is not pressed (NO), the process returns to step S310.

In FIG. 18B, a fourth purchased product (commodity D) is added in step S310 after the unsettled transaction of customer K (see FIGS. 5A and 6A) is recalled in step S270. It shows the product registration screen when it is done.

Step S312: Similar to step S12 of FIG. 4 of the first embodiment, it is determined whether or not the point card is being inserted. If the point card is being inserted (YES), the process proceeds to step S313. On the other hand, if the point card is not being inserted (NO), the process proceeds to step S316.

Step S313: Similar to step S13 of FIG. 4 of the first embodiment, the stored contents stored in the point card are re-updated (updated) based on the total amount of points to be awarded. Also, the print content of the print area of the point card is updated. After the execution of step S313, the process proceeds to step S314.

Step S314: Similar to step S14 of FIG. 4 of the first embodiment, the point card is ejected. For example, in the case of the customer K described above (when the product D is additionally registered after the recall), the point card as shown in FIG. 19A is ejected. The stored contents of the number of points of the point card of FIG. 19 (A) are the same as those of the point card of FIG. 11 (B). After the execution of step S314, the process proceeds to step S315.

Step S315: Similar to step S15 of FIG. 4 of the first embodiment, registration processing result information including product registration information and service information (point information) is generated. In the case of the customer K described above, the registration processing result information including the information of (a) to (d) of FIG. 6 (B) is generated. After the execution of step S315, the process proceeds to step S317.

Step S316: Similar to step S16 of FIG. 4 of the first embodiment, registration processing result information including product registration information is generated. After the execution of step S316, the process proceeds to step S317.

Step S317: Similar to step S17 of FIG. 4 of the first embodiment, the registration processing result information generated in step S315 or step S316 is stored in the RAM 103. After the execution of step S317, the process proceeds to step S318.
Step S318: Similar to step S18 of FIG. 4 of the first embodiment, the registration processing result information generated in step S315 or step S316 is recalled from the settlement device 20 (the settlement with the icon marked "recalling"). It is transmitted to the device 20). Then, this flowchart ends.

After the process after recalling the product registration device 10 (FIGS. 14 and 15) is executed, the settlement process (FIG. 13) is executed by the settlement device 20. When the registration processing result information is received again in step S130 for the transaction that has been recalled (the transaction in which the settlement process is suspended in step S137 of FIG. 13 and the recall request is transmitted in the subsequent step S138), the settlement device 20 releases the hold of the settlement process of the transaction (step S131 in FIG. 13). The processing (steps S132 to) after releasing the hold is as described above.

In the case of the customer K described above, when the product D is additionally registered after being recalled, the detailed receipt as shown in FIG. 19B is printed and issued in step S153 of FIG. The product registration information (a in FIG. 19 (B)), the settlement information (b in FIG. 19 (B)), and the point information (c in FIG. 19 (B)) printed on the detailed receipt in FIG. 19 (B). Is the product registration information (a in FIG. 11 (A)), the settlement information (b in FIG. 11 (A)), and the points printed on the detailed receipt (detailed receipt with the point correction code) in FIG. 11 (A). It is the same as the information (c in FIG. 11 (A)).

As described above, according to the POS system according to the second embodiment, when the transaction in which the number of points of the point card is updated is recalled, the point card used earlier in the card reading unit 112 (the point card in which the number of points is updated). Since it is possible to change the product (addition or cancellation of purchased products) on condition that is inserted, it is possible to reliably reflect the increase or decrease in the number of points caused by the product change after recall on the point card. it can.

In addition, according to the POS system according to the second embodiment, if it is noticed at the time of payment that the points were not given this time because the point card was not presented at the time of product registration, the point card should be presented after the recall. If so, points will be given this time, which was not given. In the above case, the product registration device 10 may, for example, insert the point card after recalling and simply press the subtotal key without adding or canceling the purchased product.

Although the first embodiment and the second embodiment have been described above, the configuration of the apparatus, the configuration of data, the processing shown in the flowchart, and the like can be arbitrarily changed and modified without departing from the spirit of the present invention. It is possible.

For example, according to the flowchart shown in FIG. 4, when the point card is inserted (step S12 (YES)), the registration process result information including the service information is always generated (step S15), but the service information. There may be a case where the registration process result information including the service information is generated and a case where the registration process result information does not include the service information. For example, even if a point card is inserted, if points are not given this time (when the total amount of points to be given is less than the minimum unit of points given), the point card is not inserted. Similar to (step S12 (NO)), registration processing result information that does not include service information may be generated (step S16).

Further, in step S17 of the flowchart shown in FIG. 4, the registration processing result information may be stored in the hard disk 107 instead of the RAM 103. Further, it is not necessary to execute the process of step S17 (that is, it is not necessary to store the registration process result information in the own device). When the process of step S17 is not executed, the registration process result information may be transmitted to the store controller 30 to store the registration process result information in the store controller 30. In addition, in FIG. 14, it is determined whether or not the point card was used in the recalled transaction (step S271), and whether or not the inserted point card is the point card used in the recalled transaction. (Step S280) is, for example, receiving the registration processing result information from the settlement device 20 of the destination to which the registration processing result information is transmitted (for example, receiving together with the recall request, receiving the recall request including the registration processing result information, etc.). It may be executed by inquiring to the settlement device 20 of the transmission destination (the settlement device 20 of the transmission source of the recall request) that has transmitted the registration processing result information. Further, when the registration processing result information is stored in the store controller 30, it may be executed by inquiring to the store controller 30.

Further, the various information shown in FIG. 6 is an example. For example, the basic information ((a), etc. in FIG. 6 (A)) or the service information ((d), etc. in FIG. 6 (A)) may include information regarding the final purchase date. Further, for example, the service information ((d), etc. in FIG. 6A) may include information on special points (for example, points specially given by a campaign such as a rainy day). Further, for example, the product file may be referred to for the point grant target category, and the product registration information ((b) of FIG. 6 (A), etc.) may be excluded.

Further, in the first embodiment, it was the product registration device 10 (the product registration device 10 that executed the registration process) that first updated the number of points to read the detailed receipt with the point correction code. A detailed receipt with a point correction code may be read by a product registration device 10 different from the product registration device 10 in which the number of points is first updated. That is, the points given first in the product registration device 10 different from the product registration device 10 in which the points are first given may be modified. In addition, the above-mentioned other product registration device 10 may be one that operates less.

Further, the product registration device 10 includes a card reading unit 112 (see FIG. 2), but the configuration of the device is not limited to this. For example, a card reading device (a card reading device having the same card reading function as the card reading unit 112 and capable of communicating with the product registration device; hereinafter, card reading device A) is connected to a product registration device that does not have a card reading function. (Connection by wired or wireless communication) may be used. That is, the same function as the product registration device 10 may be realized by connecting the card reading device A, which is a separate body, to the product registration device.

Further, in the first embodiment, the product registration device 10 executes the process of correcting the points (see FIG. 12), but a device other than the product registration device 10 may execute the process of correcting the points. For example, a card reading device having a card reading device (a card reading function similar to that of the card reading unit 112 and a recognition function (scanner unit) for recognizing a point correction barcode (see e in FIG. 11A). , The card reading device B. It may be possible to connect to the LAN 40 and communicate with another device) may execute the process of correcting the points. For example, when points are given by the product registration device 10 for registering purchased products and the product is changed by the settlement device 20, the points of the detailed receipt with the point correction code printed and issued by the settlement device 20. The points may be corrected by having the card reading device B read the correction bar code. That is, the points of the point card may be corrected at the service counter where the card reading device B is installed. If the points are corrected at the service counter (card reading device B), it is preferable without affecting the registration process in the product registration device 10. Therefore, in the store where the service counter (card reading device B) is installed, the points are corrected at the service counter, and in the store where the service counter (card reading device B) is not installed, the product registration device 10 (or the card reading device A) is used as in the first embodiment. You may try to correct the points in.

Further, the detail receipt with the point correction code (see FIG. 11 (A)) may be set with the expiration date of the detail receipt (that is, the point correction deadline, for example, the issue date of the detail receipt). .. Further, the point correction barcode (see e in FIG. 11 (A)) may be a barcode in which the point correction information (see d in FIG. 11 (A)) and the expiration date are coded (others). It may be a barcode that further encodes the information of). The product registration device 10 reads the point correction barcode that encodes the point correction information and the above expiration date (step S70 in FIG. 12), checks the expiration date, and points on condition that the expiration date is within the expiration date. May be modified. In addition to the point correction barcode, a barcode encoding the above expiration date may be printed.

Further, the point correction barcode (see e in FIG. 11A) may be a barcode in which the point correction information and the point card number (information for identifying the point card used at the time of product registration) are coded. It may be a barcode that is a further code of other information. In addition to the point correction barcode, a barcode encoding the above point card number may be printed.

Further, in the process after recall by the product registration device 10 of the second embodiment (see FIG. 14), it is checked whether or not the point card being inserted is the point card to be corrected in the number of points (see FIG. 14). Similarly, in step S280), in the process at the time of point correction by the product registration device 10 of the first embodiment (see FIG. 12), whether or not the point card being inserted is the point card to be corrected in the number of points. You may want to check.

Further, in the post-recall process (see FIG. 14) of the second embodiment, the product registration device 10 transmits the registration process result information to the recall source settlement device 20 (the settlement device 20 holding the settlement process). However, the registration processing result information may be transmitted to the settlement device 20 different from the settlement device 20 of the recall source. When the product registration device 10 transmits the registration processing result information to the settlement device 20 different from the recall source settlement device 20, even if the product registration device 10 transmits the information to release the hold to the recall source settlement device 20. Good.

The layout of the product registration screen (screen layout) is not limited to that shown. For example, a plurality of icons may be displayed in association with one payment machine button. For example, the display range of the preset buttons may be reduced to secure an area for displaying a plurality of icons above each checkout machine button.

Further, in the first embodiment, when the number of points increases or decreases due to a change in registration in the settlement device 20, the product registration device 10 receives a detailed receipt with a point correction code issued by the settlement device 20. The point correction information is acquired through this, but the acquisition method of the point correction information is not limited to this. For example, the settlement device 20 may transmit the point correction information (may be transmission via the store controller 30), and the product registration device 10 may receive the point correction information transmitted from the settlement device 20. Further, even if the point correction information is transmitted to the above-mentioned card reading device B (may be transmitted via the store controller 30), and the card reading device B receives the point correction information transmitted from the settlement device 20. Good.

Further, in the first embodiment, when it is necessary to correct the number of points or the like this time, the settlement device 20 includes product registration information (a in FIG. 11A) and settlement information (b in FIG. 11A). One point correction code including point information (c in FIG. 11 (A)), point correction information (d in FIG. 11 (A)), and point correction barcode (e in FIG. 11 (A)). The attached detailed receipt (FIG. 11 (A)) is issued, but a detailed receipt containing product registration information, settlement information, and point information and a point correction medium including point correction information may be issued (that is,). You may issue two sheets). The above two sheets may be issued completely separately, or may be connected and issued (partial cut) in a state where they can be easily separated.

In the above embodiment, the correction (addition) of the points granted when the points granted (points, etc. this time) increase due to the addition of the purchased product has been described, but the points granted when the points granted decrease due to the cancellation of the purchased product. The same applies to the correction (subtraction) of. When the number of points to be granted decreases, the unreflected points (points to be corrected) in the point correction information (a in FIG. 11A) of the detailed receipt with the point correction code may be expressed as a minus. For example, if product A is canceled in the settlement device 20 after registering products A to C in the product registration device 10 (when the points are reduced by 2 points this time), "unreflected points (correction points required) -2 points. May be printed.

In the above embodiment, the modification of the points granted when the points granted (points, etc. this time) increases or decreases due to the change in registration (addition or cancellation of purchased products) has been described, but due to the change in registration (cancellation of purchased products). The same applies to the modification of used points when the used points (consumed points) decrease.

For example, in the first embodiment, the product E (tax-included price 300 yen, point-giving target product) and product F (tax-included price 150 yen, point-giving target product) are registered in the product registration device 10, and the product E and product F are registered. If the product F is canceled on the settlement device 20 after using 450 points corresponding to the total amount of money (450 yen), the points will be reduced from 4 points corresponding to 450 yen to 3 points corresponding to 300 yen this time. At the same time, point correction information for reducing the points used from 450 points corresponding to 450 yen to 300 points corresponding to 300 yen may be generated and bar-coded. In the second embodiment, the points and points used this time may be reduced based on the total amount of points to be awarded after the recall.

In addition, the points used may be increased by changing the registration (addition of purchased products). For example, in the first embodiment, the product E (price including tax: 300 yen including tax, the product to be given points) is registered in the product registration device 10, and 300 points corresponding to the amount of the product E (300 yen) are used, and then the settlement device is used. When product F (150 yen including tax, product for which points are awarded) is added in 20, a confirmation screen is displayed as necessary (for example, whether or not to purchase additional products using points) and points are displayed. (If there is an operation to purchase using), this time the points will be increased from 3 points corresponding to 300 yen to 4 points corresponding to 450 yen, and the points used will be increased from 300 points corresponding to 300 yen to 450 yen. Point correction information that increases to the corresponding 450 points may be generated and bar-coded. In the second embodiment, the points and points used this time may be increased based on the total amount of points to be awarded after the recall.

Further, in the second embodiment, the transaction for which the recall request is transmitted is put on hold in order to limit the progress of the settlement process until the registration process result information is received again (step S131 in FIG. 13). (See S137 and S138), the transaction for transmitting the recall request may be completely canceled instead of being put on hold (for example, the registration processing result information of the processing may be deleted). If the mode is not set to the hold state, the hold release process (step S131) is unnecessary.

Further, in the second embodiment, the example of recalling the transaction for which the recall request has been made has been described, but the recall may be performed even if there is no recall request. That is, the product registration device 10 may recall the product. In addition, when the product registration device 10 performs a recall, the product registration device 10 may transmit information to the settlement device 20 to suspend (or cancel) the settlement process for the transaction related to the recall.

Further, in the second embodiment, in the call processing of the transaction using the point card, the change of the registered data is prohibited until the card reading unit 112 recognizes the point card. Specifically, since the process is controlled so as not to proceed to the processes of steps S275 to S318, the product registration information is not re-updated (step S315). In the transaction call processing using the point card, until the card reading unit 112 recognizes the point card, instead of the above, the processing related to the change of the registration data (in the processing of steps S275 to S318). Any one or more processes) may be prohibited. Further, the call processing of the transaction using the point card may be prohibited until the card reading unit 112 recognizes the point card. That is, in the case of a transaction using a point card, the calling process (an example of the process related to the change of the registered data) may be prohibited before the point card is inserted. In other words, the prohibition of processing related to the change of registered data means prohibition of recall, prohibition of addition or cancellation of purchased products, prohibition of subtotal operation, prohibition of transmission of information to the settlement device, issuance of accounting tickets (described later). It may be at least one of the prohibitions.

The settlement device 20 in the second embodiment may also be capable of executing the registration process of the purchased product in addition to the settlement process of the purchased product. That is, when it becomes necessary to change the registration at the time of settlement, the settlement device 20 executes the change of registration and issues a detailed receipt with a point correction code (first embodiment). After the recall, the product registration device 10 may be able to select whether to execute the registration change or the like (second embodiment).

In the first embodiment, the service information (for example, see d etc. in FIG. 6A) is generated in the product registration device 10 (see, for example, step S15 in FIG. 4) and modified (changed) in the settlement device 20. (See, for example, step S34 in FIG. 7). On the other hand, in the second embodiment, the service information (for example, see d etc. in FIG. 6A) is generated in the product registration device 10 (for example, see step S15 in FIG. 4), and also in the product registration device 10. It is modified (generated after recall) (see, for example, step S315 in FIG. 15). However, the process of generating service information is not limited to the product registration device 10. For example, the payment device 20 or the store controller 30 may generate the service information by acquiring the information necessary for generating the service information (total amount of points to be granted, etc.). Further, the process of modifying the service information is not limited to the product registration device 10 and the settlement device. For example, the store controller 30 may modify the service information by acquiring the information necessary for modifying the service information (the total amount of points to be granted after the change, etc.). That is, it suffices that the service information is generated or modified in any of the devices constituting the POS system.

The same applies to the calculation of unreflected points. That is, it is preferable that the settlement device 20 that issues the detailed receipt (see FIG. 11A) printed with the unreflected points calculates the unreflected points, but the store controller 30 and the product registration device 10 calculate the unreflected points. May be calculated. That is, it suffices that the unreflected points are calculated in any of the devices constituting the POS system. As an example, in the first embodiment, the store controller 30 (or the product registration device 10) acquires the increase / decrease amount of the total amount of points to be awarded by the product registration in the settlement device 20, and does not reflect the increase / decrease amount based on the increase / decrease amount. You may calculate the points. The store controller 30 (or the product registration device 10) that has calculated the unreflected points may transmit the calculated value of the unreflected points to the settlement device 20.

In the first embodiment (the same applies to the second embodiment), the cloudy rewrite card (PET card: thin telephone card type) has been described as the rewrite card, but the type of the rewrite card is not particularly limited. .. For example, it may be a thermal card (PET card: thin telephone card type), a leuco type rewrite card (PET card: thin telephone card type), or a leuco type rewrite card (plastic card: thick credit card type). You may. Further, in the first embodiment (the same applies to the second embodiment), the rewrite card is exemplified as the point card, but the point card is not limited to the rewrite card. For example, the card may have a storage area but no print area. In the first embodiment (the same applies to the second embodiment), a card-shaped medium (point card) is exemplified as a portable medium for storing service information (information about points), but a portable medium for storing service information is exemplified. The medium is not limited to the card shape. For example, a device (mobile phone, game machine, etc.) capable of storing service information may be used as a portable medium. When a device is used as a portable medium, for example, a device having a reading unit on which the device is placed and capable of reading and writing service information of the device mounted on the reading unit may be used. That is, the rewrite card was inserted into the card reading unit 112, but the portable medium does not have to be inserted.

In the first embodiment (the same applies to the second embodiment), the registration processing result information is transmitted from the product registration device 10 to the settlement device 20 via the LAN 40, but the product registration device 10 to the settlement device 20 The method of supplying the registration processing result information to the user is not limited to the transmission / reception of the registration processing result information via the LAN 40. For example, the product registration device 10 issues a checkout ticket printed with a two-dimensional code that encodes the registration processing result information, and the checkout device 20 reads the two-dimensional code on the checkout ticket with the scanner unit 204. The registration process result information may be supplied from the registration device 10 to the settlement device 20. The product registration device 10 issues an accounting ticket printed with a barcode that encodes a part of the registration processing result information (for example, a transaction number), and the settlement device 20 scans the barcode on the accounting ticket in the scanner unit 204. The transaction number may be acquired by reading with, and the registration processing result information corresponding to the transaction number may be acquired from the product registration device 10 (or the store controller 30).

In the first embodiment (the same applies to the second embodiment), it does not matter whether or not a server (point management server) for managing the number of points of customers is installed. That is, the point information of each customer may be stored only in the point card of each customer (operation), or the point information of each customer may be stored in the point management server in addition to the point card of each customer. It may be a memorized configuration (operation). The POS system of the first embodiment (the same applies to the second embodiment) is more effective in a configuration in which a point management server is not installed (operation in which point information exists only in the storage area of the card).

The program for realizing the POS system 1, the product registration device 10, and the settlement device 20 described above is recorded on a computer-readable recording medium, and the program is read into the computer system and executed. May be good. The term "computer system" as used herein includes hardware such as an OS and peripheral devices. Further, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, or a storage device such as a hard disk built in a computer system. Furthermore, a "computer-readable recording medium" is a volatile memory (RAM) inside a computer system that serves as a server or client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, it shall include those that hold the program for a certain period of time. Further, the program may be transmitted from a computer system in which this program is stored in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the "transmission medium" for transmitting a program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Further, the above program may be for realizing a part of the above-mentioned functions. Further, a so-called difference file (difference program) may be used, which can realize the above-mentioned functions in combination with a program already recorded in the computer system.
