Description

  Embodiments described herein relate generally to a checkout system, a settlement apparatus, and a program thereof.

  As a checkout system for mass merchandisers, there is a type in which a product data input unit and a transaction settlement unit are separated. The input unit waits for input of data related to product sales. When the data is input, the input unit generates transaction data to be settled based on the data, and transfers the transaction data to the settlement unit. The settlement unit waits for payment of the payment amount for the transaction amount calculated based on the transaction data. When a payment amount equal to or greater than the transaction amount is received, the settlement unit processes the settlement of the transaction in which the transaction amount has occurred.

  One of the payment methods for payment is electronic money settlement. Electronic money settlement uses a storage medium (IC card, mobile phone, smartphone, etc.) in which electronic money is stored in advance. If there is more electronic money balance than the transaction amount, the settlement unit deducts the transaction amount from the electronic money balance. Thus, the transaction is settled.

  If the balance of electronic money is less than the transaction amount, the settlement unit cannot withdraw the transaction amount from the balance of electronic money. In this case, as one method, the settlement unit disables electronic money settlement. The settlement unit waits for payment other than electronic money. As another method, the settlement unit sets the balance of the electronic money to “0”. The settlement unit waits for payment other than electronic money for the remaining amount obtained by subtracting the balance of electronic money from the transaction amount.

  Electronic money stored in the storage medium can be charged (deposited) by using a dedicated depositing device. Recently, it is also possible to charge electronic money using a POS (Point Of Sales) terminal constituting the checkout system. However, the conventional POS terminal cannot charge the electronic money after the data relating to the sale item is input until the transaction relating to the sale of the item is settled.

JP 2006-344123 A

  A problem to be solved by an embodiment of the present invention is that a checkout system, a payment device, and a checkout system that can charge electronic money before a transaction related to sales of a product is settled even after data related to the sales product is input It is intended to provide a program.

In one embodiment, the checkout system comprises an input unit and a payment unit. The input unit includes storage means, addition means, and output means.

  As described above, the checkout system 10 that separates the product registration device 11 that is the input unit and the payment device 12 that is the payment unit uses the data memory areas 31 and 32 shown in FIG. 3 in the product registration device 11 and the payment device 12. The RAMs 11c and 12c are respectively formed.

  The data memory area 31 is an area for storing a plurality of records RC1, RC2, RC3,... Each consisting of product code, product name, unit price, number, price, and attribute data. The product code is a unique code for identifying each product individually. For example, a product code represented by a barcode is attached to each product. The product name and unit price are the name of the product and the price per point determined by the product code of the same record. The number and the amount of money are sales data of the product determined by the product code of the same record, that is, the sales number and the sales amount for the number.

  The checkout system 10 connects a database server via the LAN 13 (not shown). This database server has a product database for setting product information such as product name and unit price in association with the product code of each product. When a product code is input in the product registration device 11 or the settlement device 12, the CPUs 11a and 12a inquire product information from the database server using the product code. Upon receiving this inquiry, the database server accesses the product database and reads the product information associated with the product code from the product database. Then, the database server notifies the merchandise information to the merchandise registration apparatus 11 or the settlement apparatus 12 via the LAN 13. The CPUs 11 a and 12 a of the merchandise registration apparatus 11 or the settlement apparatus 12 generate a record related to merchandise sales based on the merchandise information notified from the database server, and store it in the data memory area 31.

  The merchandise registration apparatus 11 receives an input of a charge amount for electronic money. When the charge amount is input, the CPU 11 a generates a record related to the charge amount and stores it in the data memory area 31. The record relating to the charge amount uses data set in advance (for example, “999999999” and “charge”) as a product code and a product name. In the record related to the charge amount, the charge amount is the unit price and “1” is the number. Therefore, the sales amount of the record related to the charge amount is equal to the charge amount.

  The attribute identifies whether the record RC1, RC2, RC3,... Is a record related to product sales or a record related to a charge amount. In the present embodiment, the attribute of the record related to product sales is set to “0”, and the attribute of the record related to the charge amount is set to “1”. Needless to say, the value of the attribute is not limited to the above example. In FIG. 3, records RC1 and RC3 indicate records related to merchandise sales, and record RC2 indicates a record related to the charge amount.

  Such a data memory area 31 is called a transaction memory. Hereinafter, the merchandise registration device 11 is represented by a transaction memory 31a, and the settlement device 12 is represented by a transaction memory 31b.

  The data memory area 32 is an area for storing the total number and the total amount. The total number is the sum of the numbers stored in the records RC1, RC2, RC3,... Stored in the transaction memory 31. The total amount is the total amount of each record RC1, RC2, RC3,... Stored in the transaction memory 31.

  Such a data memory area 32 is called a total memory. Hereinafter, the product registration device 11 is represented by the total memory 32a, and the settlement device 12 is represented by the total memory 32b.

  4 and 5 are flowcharts showing the main procedure of the control process executed by the CPU 11a of the commodity registration apparatus 11 according to the control program. 6 to 9 are schematic diagrams illustrating various screen examples displayed on the touch panels 11g1 and 11g2 of the commodity registration device 11 by the control process. 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 control processing of the procedure shown in the flowchart of FIG. First, the CPU 11a clears the transaction memory 31a and the total memory 32a (Act1). Next, the CPU 11a displays a registration screen on a part of the screen of the clerk touch panel 11g1 and the customer touch panel 11g2 (Act2).

  The registration screen represents the contents of the transaction memory 31a and the total memory 32a, and allows the clerk 21 and the shopper 22 to confirm the implementation status of the registration process. In addition, CPU11a displays various button images, such as a product button, a subtotal button, a charge button, outside the area | region used as a registration screen among the screens of the touchscreen 11g1 for shop assistants. The CPU 11a displays the charge button on a part of the screen of the customer touch panel 11g2. The product button is operated when the clerk 21 designates a product. The subtotal button is operated when the store clerk instructs to output the subtotal amount. The charge button is operated when the store clerk instructs to charge (pay) electronic money.

  In the state where the registration screen is displayed, the clerk 21 sequentially inputs the product codes of the products purchased by the shopper 22 by operating the scanner 11f or the product buttons, for example. Then, after inputting the product codes of all the purchased products, the clerk 21 touches the subtotal button.

  In addition, when a request for charging electronic money is received from the shopper 22 before touching the subtotal button, the store clerk touches the charge button. Instead of the store clerk touching the charge button, the shopper 22 may touch the charge button displayed on the customer touch panel 11g2.

  The CPU 11a displaying the registration screen confirms whether or not the product code of the product to be registered for purchase has been input (Act 3). When the product code is not input (NO in Act 3), the CPU 11a confirms whether or not the charge button is touched (Act 4). The charge button includes not only the one displayed on the clerk touch panel 11g1 but also the one displayed on the customer touch panel 11g2. When the charge button has not been touched (NO in Act 4), the CPU 11a confirms again whether or not the product code of the product to be registered for purchase has been input (Act 3). Therefore, the CPU 11a waits for a product code to be input or a charge button to be touched in the processes of Act3 and Act4.

  When a product code is input via the scanner 11f or the product button (YES in Act 3), the CPU 11a detects product information such as the product name and unit price set in the product database in association with the product code. . Further, the CPU 11a calculates a sales amount by multiplying the unit price by the number of sales. Then, the CPU 11a registers a record including a product code, a product name, a unit price, a sales quantity, a sales price, and an attribute “0” in the transaction memory 31a. Further, the CPU 11a adds the sales quantity and the sales price to the total memory 32a (Act5). Thus, if the record concerning merchandise sales is registered in the transaction memory 31a, the CPU 11a updates the registration screen so as to conform to the contents of the transaction memory 31a and the total memory 32a (Act 6).

  Here, the CPU 11a accepts input of data relating to merchandise sales, and storage means for storing transaction data (= a record whose attribute is “0”) to be settled based on the input data as a storage memory 31a. Configure.

When the charge button is touched (YES in Act 4), the CPU 11a executes a charge process (Act 7).
FIG. 5 is a flowchart specifically showing the procedure of the charge process. That is, when the charging process is started, the CPU 11a displays the charge screen SC1 (see FIG. 6) on the screen of the customer touch panel 11g2 (Act 21).

  FIG. 6 is a schematic diagram showing an example of the charge screen SC1. As shown in the figure, the charge screen SC1 includes a display area R1 and buttons B1, B2, B3, B4, B5, B6, B7, and B8.

  The button B1 is for the shopper 22 to specify a charge amount of 1000 yen. The button B2 is for the shopper 22 to specify a charge amount of 2000 yen. The button B3 is for the shopper 22 to specify a charge amount of 3000 yen. The button B4 is for the shopper 22 to specify a charge amount of 5000 yen. The button B5 is for the shopper 22 to specify a charge amount of 10,000 yen. The button B6 is for the shopper 22 to specify an input of an arbitrary charge amount other than the amounts set for the buttons B1, B2, B3, B4, and B5.

  The shopper 22 who has requested charging of electronic money confirms the presence or absence of buttons B1 to B5 on which the amount to be charged is displayed. If there is a button, the shopper 22 touches the button. If there is no button, the shopper touches button B6.

  When any one of the buttons B1 to B5 is touched, the charge amount set for the buttons B1 to B5 is displayed in the display area R1. When charging the amount displayed in the display area R1, the shopper 22 touches the button B7. When canceling the charge, the shopper 22 touches the button B8.

When the button B6 is touched, the CPU 11a switches the screen of the customer touch panel 11g2 from the charge screen SC1 to the amount input screen SC2 (see FIG. 7).
FIG. 7 is a schematic diagram showing an example of the amount input screen SC2. As shown in the drawing, the amount input screen SC2 includes a display area R2, a numeric keypad B11 of “0” to “9”, and other buttons B12, B13, B14.

  The numeric keypad B11 is for the shopper 22 to input an arbitrary charge amount. In the present embodiment, the charge amount is set in units of 1000 yen. The upper limit of the charge amount is set to 20000 yen. That is, when the charge amount is 4000 yen, 6000 yen to 9000 yen, or 11000 yen to 20000 yen, the shopper 22 inputs a numerical value of the fourth digit or more with the numeric keypad B11. For example, when 8000 yen is set as the charge amount, the shopper 22 may touch the number “8” of the numeric keypad B11. The CPU 11a displays the charge amount input via the numeric keypad B11 in the display area R2.

  When correcting the amount displayed in the display area R2, the shopper 22 touches the button B12. When the button B12 is touched, the CPU 11a clears the display area R2. When charging the amount displayed in the display area R2, the shopper 22 touches the button B13. When returning the screen of the customer touch panel 11g2 to the charge screen SC1, the shopper 22 touches the button B14.

  The CPU 11a displaying the charge screen SC1 on the customer touch panel 11g2 waits for the charge amount to be input (Act 22). When charge amount nn, nnn is input via buttons B1 to B5 on charge screen SC1 or numeric keypad B11 on amount input screen SC2 (YES in Act 22), CPU 11a displays the charge amount nn, nnn in display area R1. Or it displays on R2 (Act23). The CPU 11a confirms whether or not to execute charging (Act 24). When the OK button B7 or B13 on the charge screen SC1 or the amount input screen SC2 is touched, the CPU 11a considers that charging is performed. When the cancel button B8 on the charge screen SC1 is touched, the CPU 11a considers that the charge is cancelled.

  When executing the charge (YES in Act 24), the CPU 11a determines the product code “999999999”, the product name “charge”, the unit price “nn, nnn”, the number “1”, the amount “nn, nnn”, and the attribute “1”. Is registered in the transaction memory 31a. Further, the CPU 11a adds the number and the amount to the total memory 32a (Act 25). Thus, if the record concerning the charge amount is registered in the transaction memory 31a, the CPU 11a updates the registration screen so as to conform to the contents of the transaction memory 31a and the total memory 32a (Act 26).

  When the charge is not executed (NO in Act 24), the CPU 11a does not execute the processes of Act 25 and Act 26. Thus, the charging process ends.

  Here, the CPU 11a constitutes an adding means for accepting the input of the charge amount for the electronic money and adding the input charge amount data to the transaction memory 31.

Returning to FIG.
After updating the registration screen in Act 6 or Act 26, the CPU 11a checks whether or not the subtotal button has been touched (Act 8). When the subtotal button is not touched (NO in Act 8), the CPU 11a waits for the product code to be input again or the charge button to be touched (Act 3, Act 4).

  When a product code is input in the standby state of Act3 and Act4 (YES in Act3), the CPU 11a executes the processing of Act5 and Act6. When the charge button is touched (YES in Act4), the CPU 11a executes the Act7 charge process.

  When the subtotal button is touched (YES in Act 8), the CPU 11a generates settlement information based on the contents of the transaction memory 31a and the total memory 32a at this time (Act 9). Then, the CPU 11a displays the settlement device SC3 (see FIG. 8) on a part of the screen of the salesclerk touch panel 11g1 (Act10).

  An example of the transfer destination selection screen SC3 is shown in FIG. The transfer destination selection screen SC3 includes display areas R3, R4, R5, R6, R7, R8 and buttons B21, B22, B23, B24, B25, B6, B7.

  The display area R3 displays the total number and total amount of the total memory 32a. The display area R4 displays various messages. Buttons B21 and B22 are for the store clerk 21 to specify that the discount is applied to the total amount. The button B23 is for the clerk 21 to specify that a partial area of the screen of the clerk touch panel 11g1 is returned to the registration screen SC1.

  The display areas R5 to R8 display whether or not payment information can be transferred to each of the four payment apparatuses 12. Buttons B24 to B27 are for the store clerk 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 R5 to R8 associated with the settlement apparatus 12 in such a state, “transfer impossible” is displayed. On the contrary, “transferable” is displayed in the display areas R5 to R8 associated with the settlement apparatus 12 that has accepted the settlement information transfer. The buttons B24 to B27 may have different display 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 B24 to B27 may be hidden.

  When the transfer destination selection screen SC3 is displayed, the CPU 11a waits for the payment device 12 to be the transfer destination of payment information to be designated (Act 11). 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 any one of the buttons B21 and B22 is touched by the store clerk 21, the CPU 11a changes the total amount included in the settlement information according to an instruction from the store clerk 21 thereafter.

  The clerk 21 confirming the transfer destination selection screen SC3 determines the settlement apparatus 12 that transfers the transaction data based on the information in the display areas R5 to R8. Then, the clerk touches the buttons B24 to B27 corresponding to the settlement apparatus 12 determined as the transfer destination.

  When any of the buttons B24 to B27 on the transfer destination selection screen SC3 is touched in the standby state of Act 11, the CPU 11a considers that the settlement apparatus 12 has been designated. When payment device 12 is specified (YES in Act 11), CPU 11a outputs payment information to the specified payment device 12 (Act 12).

  Specifically, the CPU 11a sets the communication address set in the designated payment device 12 as a transmission destination address, sets the communication address set in itself as the transmission source address, and outputs the payment information to the LAN 13 so as to output the payment information. 11j is controlled. Thereby, the settlement information in which the transmission destination address and the transmission source address are set is transmitted via the LAN 13. This settlement information is received by the settlement apparatus 12 whose transmission destination address matches the communication address. The payment apparatus 12 that has received the payment information can determine the merchandise registration apparatus that is the transmission source of the payment information by storing the transmission source address of the payment information.

  Here, the CPU 11a constitutes a selection means for selecting one settlement apparatus from among the plurality of settlement apparatuses 12. Moreover, CPU11a and the communication unit 11j comprise the output means which outputs the data of the transaction memory 31a to the selected payment apparatus 12, if the input completion instruction | indication of the data which concerns on merchandise sales is received.

  When the settlement information is output, the CPU 11a displays a notification screen SC4 (see FIG. 9) on a part of the screen of the salesclerk touch panel 11g1 and the customer touch panel 11g2 (Act 13). An example of the notification screen SC4 is shown in FIG. Notification screen SC4 includes display areas R9 and R10 and a button B31. The button B31 is displayed only on the clerk touch panel 11g1. The button B31 is not displayed on the customer touch panel 11g2.

  The display area R9 displays an image for allowing the clerk 21 and the shopper 22 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 R10 represents the total number and the 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 B31 is for the clerk 21 to instruct to close the notification screen SC4. In response to the button B31 being touched, the CPU 11a finishes the information processing of the procedure shown in the flowchart of FIG. Then, the CPU 11a repeats the processing after Act1 again in the same manner as described above.

  When the buttons B24 to B27 associated with the settlement apparatus 12 that has not accepted settlement information transfer are touched, the CPU 11a does not determine Yes in Act11. 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 clerk 21 confirming the notification screen SC4 notifies the shopper 22 that payment should be made with the payment device 12 displayed in the display area R10 among the payment devices 12. At this time, the printer 11h of the merchandise registration apparatus 11 may output a paper on which the number of the settlement apparatus displayed in the display area R10 is printed, and hand this paper to the shopper 22. Upon receiving the 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 control processing of 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 merchandise registration apparatus 11 transmits settlement information from the communication unit 11j to the LAN 13 in the process of Act 12 in FIG. This settlement information is received by the communication unit 12j provided in the settlement apparatus 12 that is the destination.

  When the settlement information is received (YES in Act 32), the CPU 12a develops the settlement information in the transaction memory 31b and the total memory 32b (Act 33). That is, the CPU 12a stores a record of product name, unit price, sales quantity, sales price, and attributes included in the settlement information in the transaction memory 31b. Similarly, the CPU 12a stores the total number and total amount of purchased products included in the settlement information in the total memory 32b.

  If the settlement information is expanded in the transaction memory 31b and the total memory 32b, the CPU 12a checks whether or not the record related to the charge amount is included in the record expanded in the transaction memory 31b (Act34). That is, the CPU 12a checks the attribute of the record developed in the transaction memory 31b. When the record having the attribute “1” is detected, the CPU 12a considers that the record relating to the charge amount is included. When all the attributes of the records developed in the transaction memory 31b are “0”, the CPU 12a considers that the record relating to the charge amount is not included.

  When the record relating to the charge amount is not included (NO in Act 34), the CPU 12a displays the settlement screen SC5 (see FIG. 11) on a part of the screen of the touch panel 12g (Act 35).

  An example of the settlement screen SC5 is shown in FIG. Settlement screen SC5 includes display areas R11, R12 and buttons B41, B42, B43. The display area R11 displays operation guidance that prompts the shopper 22 who operates the payment apparatus 12 to select a payment method. The display area R12 displays the total number and the total amount stored in the total memory 32b as the number of transaction points and the transaction amount with the shopper 22. The button B11 is for the shopper 22 to specify that the settlement method is cash. The button B12 is for the shopper to specify that the payment method is electronic money. The button B13 is for the shopper 22 to specify that the clerk 21 is called.

  The shopper 22 confirming the settlement screen SC5 decides whether to settle with cash or electronic money. In the case of settlement with cash, the shopper 22 touches the button B41 and puts more cash than the total amount into the automatic change machine 12e. When paying with electronic money, the shopper 22 touches the button B42 and causes the card reader / writer 12i to read the data of the electronic money card.

  In the payment screen SC5, cash payment and electronic money payment are exemplified as payment methods, but the payment method is not limited to cash payment and electronic money payment. The settlement apparatus 12 may settle the transaction using another settlement method such as a credit card or a gift certificate.

  The CPU 12a displaying the settlement screen SC5 waits for the button B41 corresponding to cash settlement or the button B42 corresponding to electronic money settlement to be touched (Act 36). When button B41 or B42 is touched (YES in Act 36), CPU 12a executes a settlement process by the settlement method selected by the touched button (Act 37). That is, when the button B41 is touched, the CPU 12a executes a settlement process for a transaction in which the total amount has occurred on the condition that cash equal to or greater than the total amount has been inserted into the automatic change machine 12e. When the button B42 is touched, the CPU 12a executes a settlement process for a transaction in which the total amount has occurred on the condition that the balance of the electronic money read from the electronic money card by the card reader / writer 12i is equal to or greater than the total amount. To do. Since these payment processes are well-known matters in the existing self-POS terminal, the description thereof is omitted here.

  Here, the CPU 12a constitutes a processing means for receiving payment of the payment amount and processing settlement of a transaction in which the transaction amount has occurred on condition that a payment amount equal to or greater than the transaction amount (total amount) has been received.

  When the settlement process ends, the CPU 12a edits the receipt print data based on the contents of the transaction memory 31b and the total memory 32b. Then, the CPU 12a operates the printer 12h to issue a receipt (Act 38). When the receipt is issued, the CPU 12a finishes the information processing of the procedure shown in the flowchart of FIG. Then, the CPU 12a repeats the processing after Act31 again in the same manner as described above.

  On the other hand, if the record developed in the transaction memory 31b includes a record related to the charge amount (YES in Act 34), the CPU 12a displays the charge request screen SC6 (see FIG. 12) on a part of the screen of the touch panel 12g. ) Is displayed (Act 39).

  An example of the charge request screen SC6 is shown in FIG. The charge request screen SC6 includes display areas R21, 22, 23, and a button B51. The display area R21 displays operation guidance that prompts the shopper 22 who operates the settlement apparatus 12 to deposit a charge amount. The display area R22 displays the charge amount included in the record related to the charge amount. In addition, when the record developed in the transaction memory 31b includes a plurality of records relating to the charge amount, the total charge amount of each record is displayed in the display area R22. In the display area R23, the amount of money put into the automatic change machine 12e is displayed. The button B51 is for the shopper 22 to specify that the clerk 21 is called.

  The shopper 22 confirming the charge request screen SC6 causes the card reader / writer 12i to read the data of the electronic money card and inserts cash equal to or greater than the charge amount into the automatic change machine 12e.

  The CPU 12a displaying the charge request screen SC6 waits for cash to be inserted into the automatic change machine 12e (Act 40). When cash is inserted (deposited) (YES at Act 40), the CPU 12a displays the amount of money to be displayed in the display area R23. Then, the CPU 12a checks whether or not the input amount displayed in the display area R23 is equal to or larger than the charge amount displayed in the display area R22 (Act 41). If the inserted amount is less than the charged amount (NO in Act 41), the CPU 12a further waits for cash to be inserted into the automatic change machine 12e (Act 40).

  When the inserted amount is equal to or greater than the charged amount (YES in Act 41), the CPU 12a waits for the electronic money card data to be read by the card reader / writer 12i (Act 42). If the electronic money card data is read (YES in Act 42), the CPU 12a adds the charge amount to the balance of electronic money included in the electronic money card data (Act 43). Further, the CPU 12a subtracts the charge amount from the total amount stored in the total memory 32b. Further, the CPU 12a subtracts the number of records related to the charge amount from the total score stored in the total memory 32b (Act44).

  Here, when the data of the charge amount is included in the data of the transaction memory 31a output from the merchandise registration device 11, the CPU 12a is provided on the condition that a payment amount equal to or greater than the charge amount has been received by a payment method other than electronic money. The charging means for adding the charge amount to the balance of the electronic money via the card reader / writer 12i is configured. Specifically, the CPU 12a, on the condition that when the data of the charge amount is included in the data of the transaction memory 31a output from the merchandise registration device 11, a payment amount equal to or greater than the charge amount has been received by a payment method other than electronic money. The charge amount is added to the balance of the electronic money via the card reader / writer 12i, and the transaction amount is updated to the amount obtained by subtracting the charge amount.

  When the charging of the electronic money is completed, the CPU 12a confirms whether or not a change has occurred in the charge amount (Act 45). If the amount of money to be charged is larger than the amount of money to be charged, the CPU 12a considers that change has occurred. When the charge amount is equal to the input amount, the CPU 12a considers that no change has occurred.

  If a change has occurred (YES in Act 45), the CPU 12a instructs the automatic change machine 12e to pay out using the difference between the input amount and the charge amount as change (Act 46). By this command, change is paid out from the automatic change machine 12e.

  After instructing the automatic change machine 12e to pay out or when no change has occurred (NO in Act 45), the CPU 12a displays the settlement screen SC5 (see FIG. 11) on a part of the screen of the touch panel 12g (Act 35). ). Thereafter, the CPU 12a repeats the processes of Act35 to Act38 as described above.

  In the store where the checkout system 10 that operates as described above is introduced, the shopper 22 who wants to charge the electronic money of the electronic money card offers a charge to the clerk 21 at the time of accounting for the purchased product. The store clerk 21 who has received the offer for charge touches the charge button before completing the registration of the merchandise purchased by the shopper 22 in the merchandise registration apparatus 11.

  When the charge button is touched, a charge screen SC1 is displayed on the customer touch panel 11g2 of the commodity registration device 11. The shopper 22 who has confirmed the charge screen SC1 inputs the charge amount. When the charge amount is input, the merchandise registration apparatus 11 stores a record related to the charge amount in the transaction memory 31a. Records relating to purchased products are also registered in the transaction memory 31a.

  In the transaction memory 31a shown in FIG. 3, a record when a shopper 22 who purchases one product A with a unit price of 600 yen and two products B with a unit price of 1000 yen inputs a charge amount of 5000 yen. RC1, RC2, and RC3 are stored. In this state, when the clerk 21 touches the subtotal button, a transfer destination selection screen SC3 shown in FIG. 8 is displayed on the clerk touch panel 11g1. Here, the clerk 21 selects the payment device 12 of “C” as the transfer destination among the four payment devices 12 identified by “A”, “B”, “C”, and “D”, and presses the button B26. When is touched, the payment information generated based on the contents of the transaction memory 31a and the total memory 32a is transferred to the payment device 12 of “C”. Also, a notification screen SC4 shown in FIG. 9 is displayed on the clerk touch panel 11g1 and the customer touch panel 11g2. Accordingly, the shopper 22 moves to the “C” settlement apparatus 12 and performs an operation for settlement.

  At this time, since the record RC2 relating to the charge amount is included in the payment information transferred to the payment apparatus 12 of “C”, the charge request screen SC6 shown in FIG. Is displayed. Therefore, the shopper 22 first inserts a charge amount of 5000 yen into the automatic change machine 12e, and places the electronic money card in the card reader / writer 12i. At this time, for example, when the shopper 22 puts in 10,000 yen, the change amount of 5000 yen is paid out from the automatic change machine 12e. When a charge amount of 5000 yen is inserted, 5000 yen is added to the balance of electronic money stored in the electronic money card. For example, if the balance before charging is 600 yen, the balance is increased to 5600 yen by this charge.

  When the charging of the electronic money is completed, a payment screen SC5 shown in FIG. 11 is displayed on the touch panel 12g of the payment device 12 of “C”. At this time, the transaction amount displayed in the display area R12 is 2600 yen excluding the charge amount of 5000 yen. Accordingly, the shopper 22 selects a settlement method. In the case of cash settlement, the shopper 22 touches the button B41 and inserts cash having a transaction amount of 2600 yen or more into the automatic change machine 12e. In the case of electronic money settlement, the shopper 22 touches the button B42 and places an electronic money card on the card reader / writer 12i. When the shopper 22 selects electronic money settlement, the balance of the electronic money card becomes 3000 yen by payment of the transaction amount of 2600 yen.

  As described above, according to the checkout system 10 of the first embodiment, even after the data related to the sales product is input in the product registration device 11, before the transaction related to the sale of the product is settled in the settlement device 12. In addition, the shopper 22 can charge electronic money.

(Second Embodiment)
Next, a second embodiment will be described.
In the first embodiment, when a record related to the charge amount is included in the payment information, the payment device 12 first charges the charge amount to the electronic money and then calculates based on the record related to the sale of the product. Processed settlement of transaction amount. In the second embodiment, when a record related to the charge amount is included in the payment information, the payment to the electronic money and the payment for the transaction amount calculated based on the record related to the product sale in the payment apparatus 12 Are processed at once.

  That is, the second embodiment is different from the first embodiment in the information processing procedure of the settlement apparatus 12. As for the remaining portions, the second embodiment is the same as the first embodiment. Therefore, FIGS. 1 to 9 are used in the second embodiment as they are, and the description thereof is omitted.

  FIG. 13 is a flowchart showing a main procedure of control processing executed by the CPU 12a of the settlement apparatus 12 according to the control program in the second embodiment. 14 to 16 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 according to the second embodiment 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.

  When the settlement apparatus 12 is activated, the CPU 12a starts a control process of the procedure shown in the flowchart of FIG. First, the CPU 12a sets the screen of the touch panel 12g as a standby screen (Act51). After setting the screen of the touch panel 12g as a standby screen, the CPU 12a waits to receive payment information (Act 52). When the settlement information is received (YES in Act 52), the CPU 12a develops the settlement information in the transaction memory 31b and the total memory 32b (Act 53). If the settlement information is expanded in the transaction memory 31b and the total memory 32b, the CPU 12a checks whether or not the record related to the charge amount is included in the record expanded in the transaction memory 31b (Act54). When the record relating to the charge amount is not included (NO in Act 54), the CPU 12a displays the settlement screen SC5 on a part of the screen of the touch panel 12g (Act 35 in FIG. 10). Thereafter, the CPU 12a repeats the processes of Act35 to Act38 in FIG. 10 in the same manner as described above.

  On the other hand, if the record developed in the transaction memory 31b includes a record related to the charge amount (YES in Act 54), the CPU 12a displays the electronic money settlement screen SC7 (FIG. 14) on a part of the screen of the touch panel 12g. Is displayed (Act 55).

  An example of the settlement screen SC7 is shown in FIG. Settlement screen SC7 includes display areas R31, 32, and 33, and button B61. The display area R31 notifies the shopper 22 who operates the payment apparatus 12 that it is an electronic money payment. The display area R32 displays operation guidance for electronic money settlement for the shopper 22. The display area R33 displays the total number and the total amount of the total memory 32b as the transaction points and transaction amount with the shopper 22. The button B61 is for the shopper 22 to specify that the clerk 21 is called.

  The shopper 22 confirming the settlement screen SC7 in FIG. 14 causes the card reader / writer 12i to read the data of the electronic money card.

  The CPU 12a displaying the settlement screen SC7 waits for the data of the electronic money card to be read by the card reader / writer 12i (Act56). If the data of the electronic money card is read (YES in Act 56), the CPU 12a compares the balance of the electronic money included in the data of the electronic money card with the total amount of the total memory 32b, and the balance is Check if the total amount is insufficient (Act 57).

  When the balance is insufficient with respect to the total amount (YES in Act 57), the CPU 12a displays the short amount in the display area R32 of the settlement screen SC7 (Act 58). The shortage amount is calculated by subtracting the balance from the total amount.

  FIG. 15 shows the settlement screen SC7 when 7000 yen is insufficient because the balance of electronic money is 600 yen for a transaction amount of 7600 yen. In this case, the balance of the electronic money and the guidance for prompting payment of the shortage amount are displayed in the display area R32 of the settlement screen SC7.

  The shopper 22 who has confirmed the settlement screen SC7 in FIG. 15 puts more cash than the shortage into the automatic change machine 12e.

  The CPU 12a displaying the shortage amount waits for cash to be inserted into the automatic change machine 12e (Act 59). When cash is inserted (YES in Act 59), the CPU 12a checks whether or not the amount of money to be inserted is equal to or more than the shortage (Act 60). If the input amount is less than the shortage amount (NO in Act 60), the CPU 12a waits for further insertion of cash into the automatic change machine 12e (Act 59).

  When the input amount is equal to or greater than the shortage amount (YES in Act 60), the CPU 12a proceeds to the processing of Act 64.

  On the other hand, when the balance is not insufficient with respect to the total amount (NO in Act 57), the CPU 12a displays the charge amount included in the record related to the charge amount among the records developed in the transaction memory 31b in the settlement screen SC7. Is displayed in the display area R32 (Act 61). When a plurality of records relating to the charge amount are included in the records developed in the transaction memory 31b, the total charge amount of each record is displayed in the display area R32.

  FIG. 16 shows the settlement screen SC7 when there is no shortage because the balance of electronic money is 8600 yen with respect to the transaction amount 7600 yen. In this case, the balance of the electronic money and the guidance for prompting payment of the charge amount are displayed in the display area R32 of the settlement screen SC7.

  The shopper 22 confirming the settlement screen SC7 in FIG. 16 puts cash equal to or greater than the charge amount into the automatic change machine 12e.

  The CPU 12a displaying the charge amount waits for cash to be inserted into the automatic change machine 12e (Act 62). When cash is inserted (YES in Act 62), the CPU 12a checks whether or not the amount of money to be inserted is equal to or greater than the amount of charge (Act 63). When the inserted amount is less than the charged amount (NO in Act 63), the CPU 12a waits for further cash to be inserted into the automatic change machine 12e (Act 62).

  When the input amount is equal to or greater than the charge amount (YES in Act 63), the CPU 12a proceeds to the process of Act 64.

  In Act 64, the CPU 12a checks whether or not change has occurred. When the input amount is larger than the shortage amount or when the input amount is larger than the charge amount, the CPU 12a considers that change has occurred. When the input amount is equal to the shortage amount or the charge amount, the CPU 12a considers that no change has occurred.

  When change has occurred (YES in Act 65), the CPU 12a instructs the automatic change machine 12e to pay out the change between the input amount and the shortage amount or the charge amount (Act 65). By this command, change is paid out from the automatic change machine 12e.

  After a change is instructed to the automatic change machine 12e, or when no change has occurred (NO in Act 64), the CPU 12a uses the card reader / writer 12i to shortage or charge the balance of electronic money included in the electronic money card data. Add the amount (Act 66). As described above, the charge amount is the charge amount included in the record related to the charge amount among the records developed in the transaction memory 31b. When the record developed in the transaction memory 31b includes a plurality of records relating to the charge amount, the total charge amount of each record is added to the balance.

  When the charging of the electronic money is completed, the CPU 12a executes a payment process using the electronic money (Act67). That is, the CPU 12a makes a transaction in which the total amount has occurred on the condition that the balance of the electronic money read from the electronic money card by the card reader / writer 12i is equal to or greater than the total amount in the total memory 32b. Execute the settlement process. Since this settlement process is a well-known matter in existing self-POS terminals, a description thereof is omitted here.

  When the settlement process ends, the CPU 12a edits the receipt print data based on the contents of the transaction memory 31b and the total memory 32b. Then, the CPU 12a operates the printer 12h to issue a receipt (Act 68). When the receipt is issued, the CPU 12a finishes the information processing of the procedure shown in the flowchart of FIG. Then, the CPU 12a repeats the processing after Act 51 again in the same manner as described above.

  Here, the CPU 21a waits until the balance of the electronic money is read by the card reader / writer 12i when the record relating to the charge amount is included in the payment information. When the balance is less than the transaction amount calculated from the settlement information, the CPU 21a waits for the insufficient amount of payment, and on the condition that the amount of money equal to or greater than the insufficient amount has been received, the balance of the electronic money is obtained via the card reader / writer 12i. Is provided with charging means for adding the shortage amount. In this case, the CPU 21a processes transaction settlement with the balance of electronic money after the shortage amount is added.

  Further, the CPU 21a waits for a charge amount when the balance is greater than or equal to the transaction amount, and charges the amount of charge added to the electronic money balance via the card reader / writer 12i on condition that the amount greater than the charge amount has been deposited. Means. Also in this case, the CPU 21a processes transaction settlement with the balance of electronic money after the charge amount is added.

  Even in a store where the checkout system 10 that operates as described above is introduced, the shopper 22 who wants to charge the electronic money of the electronic money card is charged from the charge screen SC1 displayed on the customer touch panel 11g2 of the product registration apparatus 11. Is the same as in the first embodiment.

  Here, it is assumed that a shopper 22 who purchases one product A with a unit price of 600 yen and two products B with a unit price of 1000 yen inputs a charge amount of 5000 yen. Further, it is assumed that the store clerk 21 selects the payment device 12 of “C” as the transfer destination among the four payment devices 12 identified by “A”, “B”, “C”, and “D”. Then, the shopper 22 moves to the “C” settlement apparatus 12 and performs an operation for settlement.

  At this time, the payment information transferred to the payment device 12 of “C” includes the record RC2 relating to the charge amount, so the electronic money payment screen SC7 shown in FIG. 14 is displayed on the payment device 12 of “C”. It is displayed on the touch panel 12g. That is, a total amount of 7600 yen including the total amount of purchased goods 2600 yen and charge amount 5000 yen is displayed as the transaction amount.

  Therefore, the shopper 22 places an electronic money card on the card reader / writer 12i. At this time, assuming that the balance of the electronic money is 600 yen, the balance is insufficient with respect to the transaction amount. Therefore, as shown in FIG. 15, there is a guidance that prompts the payment screen SC7 to deposit the insufficient amount of 7000 yen. Is displayed.

  The shopper then puts more cash than the shortage amount, for example 10,000 yen, into the automatic change machine 12e. Then, in the settlement apparatus 12 of “C”, 3000 yen is paid out as change from the automatic change machine 12e. Further, the total amount of purchased goods 2600 yen is reduced from the electronic money balance 7600 yen charged with the shortage amount 7000 yen, and the electronic money balance is rewritten to 5000 yen.

  Thus, the shopper 22 paid part of the purchase amount of 2600 yen with the balance of electronic money of 600 yen, paid the remainder with cash (the amount once charged to the electronic money), and charged the electronic money with 5000 yen. It becomes equivalent.

  On the other hand, if it is assumed that the balance of electronic money is 8600 yen, the balance is sufficient for the transaction amount, and as shown in FIG. 16, guidance is displayed on the settlement screen SC7 urging to deposit a charge amount of 5000 yen. The

  Therefore, the shopper puts cash, for example, 10,000 yen that is greater than the charge amount, into the automatic change machine 12e. If it does so, in the settlement apparatus 12 of "C", 5000 yen will be paid out as change from the automatic change machine 12e. In addition, the total amount of purchased goods 2600 yen is reduced from the electronic money balance 13600 yen charged 5000 yen, and the electronic money balance is rewritten to 11000 yen.

  Thus, the shopper 22 pays a purchase amount of 2600 yen with an electronic money balance of 8600 yen and charges 5000 yen to the electronic money.

  As described above, the checkout system 10 of the second embodiment can achieve the same effects as those of the first embodiment.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, the charge screen SC1 is displayed on the screen of the customer touch panel 11g2, but the charge screen SC1 may be displayed on the screen of the clerk touch panel 11g1. In this case, the store clerk may input the charge amount offered by the shopper 22 from the charge screen SC1.

  Moreover, in the said embodiment, although the case where the charge amount was deposited in cash was shown, it is not necessarily limited to cash. The charge amount may be deposited by a method other than electronic money such as a gift certificate or a credit card.

  In the above embodiment, a semi-self type checkout system is exemplified, but the present invention is not necessarily limited to a semi-self type checkout system. For example, even in a checkout system in which a clerk operates a payment unit, the electronic money charging function can be applied in the same manner as in each embodiment. In addition, the electronic money charging function can be applied to a checkout system in which the input unit and the settlement unit are not separated and integrated, that is, a so-called face-to-face POS terminal or a self-type POS terminal.

  Moreover, although the said embodiment illustrated the checkout system of the transaction which concerns on sale of goods, for example, in the checkout system of the transaction which relates to service provisions, such as usage fees, such as a parking lot and a sports facility, admission fees, etc. Can be applied similarly.

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.
