FIG. 10 is a flowchart showing the main procedure of control processing executed by the CPU 12a of the settlement apparatus 12 according to the control program. 11 to 12 are schematic diagrams illustrating various screen examples displayed on the touch panel 12g of the settlement apparatus 12 by the control process. Hereinafter, the operation of the checkout system 10 will be described with reference to these drawings. Note that the content of the processing described below is an example, and various processing that can obtain the same result can be used as appropriate.

First, the operation of the merchandise registration apparatus 11 will be described.
When the merchandise registration apparatus 11 is activated in a mode for registering purchased merchandise, the CPU 11a starts processing according to the procedure shown in the flowchart of FIG. First, the CPU 11a clears the data tables 31a to 34a (Act1). Next, the CPU 11a displays a card inquiry screen SC1 (see FIG. 6) on a part of the screen of the touch panel 11g, and accepts an input of a membership card (Act2: card accepting means).

  As shown in FIG. 6, the card inquiry screen SC1 includes display areas R1, R2 and buttons B1, B2. The display area R1 displays a message for inquiring about the presence of a membership card. The display area R2 displays an image of a usable membership card. The button B1 is for the employee 21 to specify that the transaction is with the shopper 22 who has the membership card displayed in the display area R2. The button B1 is for designating that the transaction is with the shopper 22 who does not have the membership card displayed in the display area R2.

  In the present embodiment, a member service that allows a user to purchase a product at a member price is applied only to members who have a membership card. Therefore, even if a member forgets his / her membership card, he / she cannot receive the membership service and must purchase the product at a normal unit price.

  Accordingly, the employee 21 confirming the card inquiry screen SC1 inquires of the shopper 22 who has applied for registration of the purchased product whether there is a membership card. When the shopper 22 presents the member code, the employee 21 touches the button B1 and causes the card reader / writer 11i to read the data of the member card. On the other hand, when the shopper 22 does not present the member code, the employee 21 touches the button B2.

  After displaying the card inquiry screen SC1, the CPU 11a waits for either button B1 or B2 to be touched (Act3). When it is detected that the button B1 is touched, the CPU 11a determines that the transaction is a member transaction (YES in Act3). In this case, the CPU 11a sets the member flag of the member table 31a to “1” (Act4). The CPU 11a registers the member number and the accumulated points in the member table 31a (Act 5). The membership number is information read from the membership card by the card reader / writer 11i. The accumulated point is information stored in the member database in association with the member number. Note that the processing procedure of Act4 and Act5 is not limited to the embodiment. The front and back may be reversed.

  When it is detected that the button B2 is touched instead of the button B1, the CPU 11a determines that the commercial transaction is by a non-member (NO in Act3). In this case, the CPU 11a does not execute the processes of Act4 and Act5.

  When the processing of Act4 and Act5 is completed or it is determined that the transaction is a non-member transaction, the CPU 11a displays a registration screen SC2 (see FIG. 7) on a part of the screen of the touch panel 11g (Act6).

  The registration screen SC2 represents the contents of the registered product table 32a and the total table 33a, and allows the employee 21 to confirm the implementation status of the registration process. An example of the registration screen SC2 is shown in FIG. Registration screen SC2 includes display areas R3 and R4. The display area R3 displays the product name, number, and unit price of the product that is most recently registered for purchase, and the total number and total price of the purchased product after the product is registered. The display area R4 displays a list of product names, numbers, unit prices, and amounts related to products for which purchase registration has been made prior to the products shown on the registration screen SC2.

  In addition, although illustration is abbreviate | omitted, CPU11a is outside the area | region used as registration screen SC2 among the screens of the touch panel 11g, The product button for the employee 21 to specify goods, and various function buttons, such as a subtotal button. indicate.

  The employee 21 who has confirmed that the card inquiry screen SC1 has switched to the registration screen SC2 operates, for example, the scanner 11f and a product button, and sequentially inputs the product code of the product purchased by the shopper 22. Then, after inputting the product codes of all the purchased products, the employee 21 touches the subtotal button.

  The CPU 11a displaying the registration screen SC2 waits for the acquisition of the product code of the product to be registered for purchase (Act 7). When the product code input via the scanner 11f or the product button is acquired (YES in Act 7), the CPU 11a associates the product code with the product name, normal unit price, member price, etc. set in the product database. Product information is detected (Act8). Further, the CPU 11a checks whether or not the member flag of the member table 31a is set to “1” (Act 9).

  When the member flag is not set to “1” (NO in Act 9), the CPU 11a selects the normal unit price from the product information (Act 10). When the member flag is set to “1” (YES in Act 9), the CPU 11a selects a member unit price from the product information (Act 11).

  When the normal unit price or the member unit price is selected, the CPU 11a calculates the sales amount by multiplying the normal unit price or the member unit price by the number of sales. Then, the CPU 11a registers the product sales data including the product code, the product name, the normal unit price, the member unit price, the sales quantity, and the sales price as one record in the registered product table 32a (Act12: registration means). In addition, the CPU 11a adds the sales quantity and the sales price to the total table 33a. Then, the CPU 11a updates the registration screen SC2 so as to conform to the contents of the registered product table 32a and the total table 33a (Act 13).

  After updating the registration screen SC2, the CPU 11a checks whether or not the product code of the product to be purchased and registered is acquired (Act 14). If the product code has not been acquired (NO in Act 14), the CPU 11a checks whether or not the subtotal button has been touched (Act 15). When the subtotal button is not touched (NO in Act 15), the CPU 11a confirms again whether or not the product code has been acquired (Act 14). Therefore, the CPU 11a waits for a product code to be acquired or a subtotal button to be touched as Act14 and Act15. Note that the CPU 11a may confirm the occurrence of another event such as another operation being performed in the standby state, and may shift to processing according to the occurrence event.

  When the product code is acquired in the standby state of Act14 and Act15 (YES in Act14), the CPU 11a returns to the processing of Act8. Then, the CPU 11a repeats the subsequent processing in the same manner as described above.

  If the subtotal button is touched in the standby state of Act14 and Act15 (YES in Act15), the CPU 11a proceeds to the processing of Act16 in FIG. That is, the CPU 11a generates payment information based on the contents of the member table 31a, the registered product table 32a, and the total table 33a at this time (Act 16: generation means). Then, the CPU 11a displays a transfer destination selection screen SC3 (see FIG. 8) on a part of the screen of the touch panel 11g (Act 17).

  The settlement information includes a list of product names of registered products, normal unit price, member unit price, sales quantity and sales price, total quantity and total price of purchased products, member flag, member number and accumulated points. Accordingly, in the case of a commercial transaction by a member, the settlement information includes a member flag of state “1” indicating that the input of the member card has been accepted. The settlement information also includes a membership number and accumulated points acquired by accepting the input of the membership card. On the other hand, in the case of a commercial transaction by a non-member, the settlement information includes a member flag of a state “0” indicating that the member card input has not been accepted.

  An example of the transfer destination selection screen SC3 is shown in FIG. The transfer destination selection screen SC3 includes display areas R5, R6, R7, R8, R9, R10 and buttons B3, B4, B5, B6, B7, B8, B9, B10.

  The display area R5 displays the total number and total amount of the total table 33a. The display area R6 displays various messages. Buttons B3 and B4 are used by the employee 21 to specify that the discount is applied to the total amount. The button B5 is for the employee 21 to specify that a cash voucher such as a gift certificate is used as a payment method for the purchased merchandise. The button B6 is for the employee 21 to specify that a part of the screen of the touch panel 11g is returned to the registration screen SC2.

  The display areas R7 to R10 display whether or not the payment information can be transferred to each of the four payment apparatuses 12. Buttons B <b> 7 to B <b> 10 are used for the employee 21 to specify the transfer of payment information to each of the four payment apparatuses 12. The payment apparatus 12 does not accept transfer of payment information during execution of payment processing. In the display areas R7 to R10 associated with the settlement apparatus 12 in such a state, “transfer impossible” is displayed. On the contrary, “transfer is possible” is displayed in the display areas R7 to R10 associated with the settlement apparatus 12 that accepts settlement information transfer. The buttons B7 to B10 may be displayed in different forms depending on whether or not the associated payment apparatus 12 accepts payment information transfer. Alternatively, when the associated payment apparatus 12 does not accept transfer of payment information, the buttons B7 to B10 may be hidden.

  When the transfer destination selection screen SC3 is displayed, the CPU 11a confirms whether or not the product code of the product to be registered for purchase has been acquired (Act 18). When the product code is not acquired (NO in Act 18), the CPU 11a checks whether or not payment by a cash voucher is designated (Act 19). When payment by a cash voucher is not specified (NO in Act 19), the CPU 11a confirms whether or not the payment device 12 as a transfer destination of payment information is specified (Act 20). When payment device 12 is not specified (NO in Act 20), CPU 11a checks again whether or not a product code has been acquired (Act 18). Therefore, the CPU 11a waits for a product code to be acquired as Act18 to Act20, payment by a cash voucher is specified, or a settlement apparatus 12 is specified. The CPU 11a may confirm the occurrence of another event such as another operation being performed in the standby state here, and may shift to processing according to the occurrence event. For example, when one of the buttons B3 and B4 is touched by the employee 21, the CPU 11a changes the total amount included in the settlement information in accordance with an instruction from the employee 21 thereafter.

  When the product code is acquired in the standby state of Act 18 to Act 20 (YES in Act 18), the CPU 11a returns a partial area of the screen of the touch panel 11g to the registration screen SC2 (Act 21). Thereafter, the CPU 11a proceeds to the process of Act8 in FIG. 4 and repeats the subsequent processes in the same manner as described above.

  When the button B5 is touched by the employee 21 in the standby state of Act 18 to Act 20, the CPU 11a considers that the payment by the cash voucher is designated (YES in Act 19). CPU11a displays a voucher information input screen on a part of screen of the touch panel 11g (Act22). The voucher information input screen is a screen that prompts the employee 21 to input the face amount and the number of vouchers used for payment. The employee 21 confirming the voucher information input screen operates, for example, the touch panel 11g according to the screen to input the face value and the number of vouchers to be paid by the shopper 22.

  When the voucher information input screen is displayed, the CPU 11a waits for the voucher information to be input (Act 23). When the face value and the number of the voucher are input as the voucher information (YES in Act 23), the CPU 11a calculates the payment amount by the voucher based on the face amount and the number. Then, the CPU 11a registers this payment amount in the payment table 34a in association with the payment type indicating the voucher payment (Act 24). The CPU 11a edits the payment information so as to include the voucher payment information registered in the payment table 34a (Act 25).

  Next, the CPU 11a displays a message for notifying the employee 21 that the payment device 12 to which the payment information is to be transferred is designated on a part of the transfer destination selection screen SC3, for example, the display area R6 (Act 26). Then, the CPU 21 waits for the settlement device 12 to be designated (Act 27).

  If any of the buttons B7 to B10 on the transfer destination selection screen SC3 is touched by the employee 21 in the standby state of Act 18 to Act 20 or the standby state of Act 27, the CPU 11a considers that the settlement apparatus 12 has been designated. When the settlement apparatus 12 is designated (YES in Act 20 or Act 27), the CPU 11a transmits settlement information to the designated settlement apparatus 12 (Act 28: transmission means). Specifically, the CPU 11a controls the communication unit 11j so that the payment information is transmitted to the LAN 13 with the designated payment device 12 as a destination. As a result, the payment information is transmitted to the payment apparatus 12 via the LAN 13.

  When the settlement information is transmitted, the CPU 11a displays a notification screen SC4 (see FIG. 9) on a part of the screen of the touch panel 11g (Act 29). An example of the notification screen SC4 is shown in FIG. Notification screen SC4 includes display areas R11 and R12 and button B11.

  The display area R11 displays an image for causing the employee 21 to recognize that the semi-self payment is selected. The semi-self-settlement is a settlement form in which settlement processing is executed in the settlement apparatus 12 in response to an operation by the shopper 22. The display area R12 represents the total number and total amount included in the payment information, and displays which of the four payment apparatuses 12 has transferred the payment information including such contents. The button B11 is for the employee 21 to instruct to close the notification screen SC4. In response to the button B11 being touched, the CPU 11a returns to the process of Act1 in FIG. 4 and repeats the subsequent processes in the same manner as described above.

  When the buttons B7 to B10 associated with the settlement apparatus 12 that has not accepted the settlement information transfer are touched, the CPU 11a does not determine Yes in Act 20 or Act 27. Thus, the CPU 11a does not accept designation of the settlement apparatus 12 that does not accept transfer of settlement information. Therefore, if all of the payment devices 12 are in an operation stop state or are in an operation state in which transfer of payment information is not accepted, the CPU 11a does not wait for designation of the payment device 12.

  The employee 21 confirming the notification screen SC4 notifies the shopper 22 that the settlement apparatus 12 displayed in the display area R12 of each settlement apparatus 12 should perform settlement. Upon receiving this notification, the shopper 22 moves to the designated settlement apparatus 12 and performs an operation for settlement.

Next, the operation of the settlement apparatus 12 will be described.
When the settlement apparatus 12 is activated, the CPU 12a starts processing according to the procedure shown in the flowchart of FIG. First, the CPU 12a sets the screen of the touch panel 12g as a standby screen (Act31). The standby screen represents that there is no payment processing status, and what information is represented may be arbitrary. For example, it is assumed that the standby screen displays a message indicating that payment processing cannot be performed, or displays an arbitrary image indicating an advertisement or the like as a screen saver. After setting the screen of the touch panel 12g as a standby screen, the CPU 12a waits to receive payment information (Act32).

  As described above, the CPU 11a of the commodity registration apparatus 11 transmits settlement information from the communication unit 11j to the LAN 13 in the process of Act 28 in FIG. This settlement information is received by the communication unit 12j provided in the settlement apparatus 12 that is the destination (reception means).

  When the payment information is received (YES in Act 32), the CPU 12a expands the payment information in the member table 31b, the registered product table 32b, the total table 33b, and the payment table 34b (Act 33).

  That is, when the member flag included in the payment information is “0”, the CPU 12a stores the member flag in the member table 31b. When the member flag included in the payment information is “1”, the CPU 12a stores the member number and the accumulated points included in the payment information together with the member flag in the member table 31b.

  The CPU 12a stores a list of the product name, normal unit price, member unit price, sales quantity, and sales price of the registered product included in the settlement information in the registered product table 32b. Further, the CPU 12a stores the total number and total amount of purchased products included in the settlement information in the total table 33b. Further, when the payment information includes the voucher payment information, the CPU 12a stores the payment type and the payment amount constituting the voucher payment information in the payment table 34b.

  Next, the CPU 12a checks the member flag stored in the member table 31b. That is, the CPU 12a determines whether or not the received settlement information is information that has been processed as a member's commercial transaction by the member registration card 11 being presented with a membership card (Act34: determination means). When the member flag is “1”, the received settlement information is information processed as a member's commercial transaction. In this case (YES in Act 34), the CPU 12a displays the first settlement screen SC5 (see FIG. 11) on a part of the screen of the touch panel 12g (Act 40: selection display means). Details of the first settlement screen SC5 will be described later.

  On the other hand, when the member flag is “0”, the received payment information is information processed as a non-member commercial transaction. In this case (NO in Act 34), the CPU 12a checks whether or not the voucher payment information is stored in the payment table 34b (Act 35). If the voucher payment information is not stored in the payment table 34b, the merchandise registration apparatus 11 has not settled. In this case (NO in Act 35), the CPU 12a displays the card inquiry screen SC1 on a part of the screen of the touch panel 12g and accepts the input of the membership card (Act 36: confirmation display means). The card inquiry screen SC1 is the same as the card inquiry screen SC1 displayed in the Act2 process in the merchandise registration apparatus 11. For this reason, explanation here is omitted.

  The shopper 22 confirming the card inquiry screen SC1 confirms again whether or not there is a membership card. When the customer card is not possessed, the shopper 22 touches the button B2. On the other hand, when a member card that is not found at the time of registering the purchased product is found, the shopper 22 touches the button B1 and causes the card reader / writer 12i to read the data of the member card.

  After displaying the card inquiry screen SC1, the CPU 12a waits for either button B1 or B2 to be touched (Act 37). When it is detected that the button B2 is touched (NO in Act 37), the CPU 12a displays the second settlement screen SC6 (see FIG. 12) on a part of the screen of the touch panel 12g (Act 41: selection display). means). Details of the second settlement screen SC6 will be described later.

  On the other hand, when it is detected that the button B1 is touched (YES in Act 37), the CPU 12a rewrites the member flag in the member table 31b to “1”. The CPU 12a registers the member number and the accumulated points in the member table 31b (Act 38). The membership number is information read from the membership card by the card reader / writer 12i. The accumulated point is information stored in the member database in association with the member number.

  Next, the CPU 12a rewrites the data of the amount for each record stored in the registered product table 32b to a value obtained by multiplying the member price of the record by the number. Further, the total amount data in the total table 33b is rewritten with the sum of the amounts of all the records stored in the registered product table 32b (Act 39: update means). Thereafter, the CPU 12a displays the first settlement screen SC5 (see FIG. 11) on a part of the screen of the touch panel 12g (Act 40: selection display means).

  An example of the first payment screen SC5 is shown in FIG. 11, and an example of the second payment screen SC6 is shown in FIG. First settlement screen SC5 includes display areas R21, R22, R23 and button B21. Second settlement screen SC6 includes display areas R31, R32 and button B31.

  The display area R21 and the display area R31 both display payment method selection buttons B41, B42, and B43. The display area R22 and the display area R32 both display the total number and the total amount of the total table 33b. The display area R23 displays the accumulated points of the member table 31b. Button B21 and button B31 are for the shopper 22 to specify that the employee 21 is called.

  When the button B21 or the button B31 is touched, a call signal is transmitted from the settlement apparatus 12 to the commodity registration apparatus 11 that is the settlement information transmission source via the LAN 13. In the commodity registration apparatus 11 that has received this call signal, for example, a call recommendation screen is displayed on the touch panel 11g. On this call recommendation screen, information indicating the settlement apparatus 12 that is the call signal transmission source is displayed. Therefore, the employee 21 can easily know that the call has been received from the shopper who operates the corresponding settlement apparatus 12.

  The selection button B41 is for the shopper 22 who selects cash payment to touch. The selection button B42 is for the shopper 22 who selects credit payment to touch. The selection button B43 is for the shopper 22 who selects point payment to touch. However, on the second settlement screen SC6, the selection button B43 is displayed in gray scale, and the shopper 22 cannot touch it. That is, the first settlement screen SC5 is a screen for the shopper 22 to select one of payment methods from cash payment, credit payment, and point payment. The second settlement screen SC6 is a screen for the shopper 22 to select either a cash payment method or a credit payment method, and the point payment cannot be selected although the selection button B43 is displayed.

  The shopper 22 who has confirmed the first settlement screen SC5 or the second settlement screen SC6 selects any one of the payment methods displayed in the display area R21 or the display area R31, and selects the corresponding selection button. Touch B41, B42 or B43. Then, the payment device 12 performs a payment operation for the selected payment method.

  The CPU 12a displaying the first settlement screen SC5 or the second settlement screen SC6 waits for the selection button B41, B42 or B43 to be touched (Act42). When selection button B41, B42 or B43 is touched (YES in Act 42), CPU 12a considers that the payment method corresponding to touched selection button B41, B42 or B43 has been selected. The CPU 12a executes a settlement process by the selected payment method (Act 43: processing means). That is, when the selection button B41 is touched, the CPU 12a executes a settlement process for cash payment. When the selection button B42 is touched, the CPU 12a executes a settlement process for credit payment. When the selection button B43 is touched, the CPU 12a executes a settlement process for the point payment using the accumulated points of the member table 31b.

  Since these settlement processes are all well-known processes, detailed description thereof is omitted. Incidentally, in the case of a member transaction in which the member flag is set to “1”, in this settlement processing, for example, service points are calculated according to the total amount. This service point is transmitted to the database server together with the member number in the member table 31b, and is accumulated for each member in the member database.

  When the settlement process is completed, the CPU 12a operates the printer 12h to issue a receipt (Act44). After issuing the receipt, the CPU 12a returns to the process of Act 31, and repeats the subsequent processes in the same manner as described above.

  As described above, in the checkout system 10, when the payment information of the commercial transaction by the non-member is transferred from the merchandise registration device 11 to the payment device 12, the card inquiry screen SC1 is displayed on the touch panel 12g of the payment device 12. Therefore, even if the shopper 22 has finished registering the purchased product as a non-member in the product registration apparatus 11 because the member code has not been found, the presence / absence of the membership card will be reconfirmed before the settlement by the settlement apparatus 12. . When the customer card is found, the shopper 22 touches the button B1 on the card inquiry screen SC1 and causes the card reader / writer 12i to read the data of the member card. Then, in the settlement apparatus 12, the unit price of each purchased product is changed from the normal unit price to the member unit price, and the purchase price is recalculated. That is, the settlement information for the commercial transaction by the non-member is changed to the settlement information for the commercial transaction by the member. Therefore, the shopper 22 who has finished registering the purchased product as a non-member in the product registration device can receive the member service that can be purchased at the member price and the member service that gives points at the settlement device 12.

  Further, in the checkout system 10, when the payment device 12 receives the payment information of the commercial transaction by the member, the first payment screen SC5 is displayed on the touch panel 12g of the payment device 1. Even when the payment device 12 receives payment information for commercial transactions by non-members, the first payment screen SC5 is displayed when an operation indicating that there is a member card is performed on the card inquiry screen SC1. . On the other hand, when an operation indicating no membership card is performed on the card inquiry screen SC1, the second settlement screen SC6 is displayed. The second settlement screen SC6 is also displayed when non-member settlement information including voucher payment information is received.

  The first settlement screen SC5 can select point payment as a payment method, but the second settlement screen SC6 cannot be selected. The first settlement screen SC5 is displayed when a commercial transaction by a member is established. Points can be paid for member transactions. Therefore, the shopper 22 who is a member can select point payment as a payment method. In other words, the non-member shopper 22 does not select point payment by mistake.

  On the other hand, on the second settlement screen SC6, a button B43 for selecting point payment is displayed in a grayscale manner that cannot be selected. Therefore, it is possible to appeal strongly that non-member shoppers can pay points when they become members.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, there are three types of payment methods that can be selected on the settlement screen: cash payment, credit payment, and point payment. However, other payment methods such as electronic money payment may be added to provide four or more types. Or it is good also as two types of cash payment and point payment except credit payment. Further, in the case of membership service operation in which points are not applied to payment, for example, only one pattern of the second settlement screen SC2 may be used.

  In the above embodiment, the card inquiry screen SC1 displayed on the product registration apparatus 11 and the card inquiry screen SC1 displayed on the settlement apparatus 12 are described as the same screen. However, the same screen is not necessarily required. In short, any mode can be used as long as it can inquire the shopper 22 about the presence of a membership card and specify the result.

In addition, although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
