FIG. 5 is an example of the payment receipt 40 printed by the printing unit 111 of the commodity registration apparatus 10.
FIG. 5A is an example of a receipt 40 for payment in the present embodiment. As shown in the figure, the two-dimensional code C1 is printed on the payment receipt 40. The two-dimensional code C1 records two-dimensional code recording information including transaction identification information and merchandise identification information of purchased products. The merchandise registration apparatus 10 generates two-dimensional code record information including the transaction identification information and the merchandise identification information of the purchased product, converts the generated two-dimensional code record information into a two-dimensional code, and prints it on the payment receipt 40. The settlement apparatus 20 reads the two-dimensional code C1 with the scanner unit 204, and extracts the transaction identification information and the merchandise identification information of the purchased merchandise.

In the present embodiment, the two-dimensional code C1 is printed on the payment receipt 40. However, the code to be printed may be any code that can identify each transaction, such as a barcode that records transaction identification information. FIG. 5B is an example of a payment receipt 40 on which a barcode C2 is printed. The bar code C2 printed on the payment receipt 40 records transaction identification information. In this case, the merchandise registration device 10 transmits the transaction identification information and the merchandise identification information of the purchased merchandise to the store controller, and prints the barcode C1 on which the transaction identification information is recorded on the payment receipt 40. When the store controller receives the transaction identification information and the product identification information of the purchased product from the product registration apparatus 10, the store controller stores the received transaction identification information and the product identification information of the purchased product in association with each other. The settlement apparatus 20 reads the barcode C1 with the scanner unit 204 and extracts the transaction identification information. Further, the settlement apparatus 20 acquires the product identification information of the purchased product corresponding to the transaction identification information by transmitting the extracted transaction identification information to the store controller. When the store controller receives the transaction identification information from the settlement apparatus 20, the store controller returns the product identification information of the purchased product corresponding to the received transaction identification information.
Here, the two-dimensional code C1 and the bar code C2 are settlement codes for settlement of each account.

FIG. 6 is a schematic diagram showing the positional relationship between the payment receipt 40 and the scanner unit 204 in the payment apparatus 20.
When the two-dimensional code C1 printed on the payment receipt 40 is positioned in the two-dimensional code reading area A of the scanner unit 204, the scanner unit 204 reads the two-dimensional code C1. The CPU 201 of the settlement apparatus 20 starts the settlement process when the scanner unit 204 reads the two-dimensional code C1. The shopper C places the checkout receipt 40 so that the two-dimensional code C1 is positioned in the two-dimensional code reading area A of the scanner unit 204, and starts the checkout.
Here, if the payment receipt 40 that has already been settled remains in the two-dimensional code reading area A, when the next shopper C starts payment, the two-dimensional code of the remaining payment receipt 40 that has already been settled. The scanner unit 204 may read C1. Therefore, when the scanner unit 204 reads the settled two-dimensional code C1, the CPU 201 of the settlement apparatus 20 in the present embodiment discards the read information of the two-dimensional code C1 without causing an error. Thereby, it is possible to prevent the settlement process from being performed again based on the settlement receipt 40 that has been settled.

Hereinafter, the settlement process executed by the settlement apparatus 20 will be described. FIG. 7 is a flowchart showing a part of the procedure of the settlement process executed by the settlement apparatus 20.
When the CPU 201 reads the settlement program stored in the ROM 202 and expands it in the RAM 203 and starts executing the expanded settlement program, the settlement apparatus 20 starts the settlement process according to the flowchart of FIG.
The settlement apparatus 20 stores in advance the product data file supplied from the store controller in the RAM 203 before executing the settlement process.

  First, in the process of step S101, the CPU 201 determines whether or not the transaction identification information has been read. Specifically, the CPU 201 determines whether or not the scanner unit 204 has read the two-dimensional code C1. When the two-dimensional code C1 printed on the payment receipt 40 is positioned so as to be readable in the two-dimensional code reading area A of the scanner unit 204, the scanner unit 204 reads the two-dimensional code C1. . Next, the CPU 201 extracts the two-dimensional code recording information recorded in the two-dimensional code C1 read by the scanner unit 204 and stores it in the RAM 203. Then, the CPU 201 reads the transaction identification information from the two-dimensional code record information. If the transaction identification information has not been read (that is, if the scanner unit 204 has not read the two-dimensional code), the CPU 201 executes the process of step S101 again. On the other hand, when the CPU 201 reads the transaction identification information (that is, when the scanner unit 204 reads the two-dimensional code), the CPU 201 proceeds to the process of step S102.

  Subsequently, in the process of step S102, the CPU 201 determines whether or not the read transaction identification information has been settled. Specifically, when the read transaction identification information matches the already settled transaction identification information stored in the RAM 203, the CPU 201 determines that the transaction identification information has been settled. If the accounting identification information has been settled, the process proceeds to step S103. If the accounting identification information has not been settled, the process proceeds to step S104.

  When the accounting identification information has been settled (step S102: Yes), in the processing of step S103, the CPU 201 excludes the accounting identification information (receipt for settlement 40) from the settlement and stores the accounting identification stored in the RAM 203. The information two-dimensional code record information is deleted (discarded), and the process returns to step S101. At this time, the CPU 201 does not display an error on the display unit 205.

  On the other hand, when the transaction has not been settled (step S102: No), in the process of step S104, the CPU 201 stores the product data (product name and sales price, etc.) of the product identification information included in the two-dimensional code recording information stored in the RAM 203. ) Is read from the product data table in the RAM 203, and purchase product table data is generated. Then, the CPU 201 displays, on the display unit 205, an accounting menu including display items of the purchase product table data of the shopper C, the number of purchases, the subtotal purchase amount, and the payment request amount based on the generated purchase product table.

  Subsequently, in the process of step S105, the CPU 201 causes the display unit 205 to display an instruction for proceeding with the settlement operation. Thereafter, the shopper pays in accordance with the instruction displayed on the display unit 205. Specifically, the CPU 201 causes the display unit 205 to display a settlement request menu including the total purchase amount (payment request amount) as a display item. When money corresponding to the payment request amount is inserted by the shopper C into the insertion port of the change machine 210, the change machine 210 deposits the inserted money and notifies the CPU 201 of the amount of money. Then, the CPU 201 stores the deposit amount in the RAM 203. The CPU 201 calculates the difference between the payment request amount stored in the RAM 203 and the deposit amount (deposit amount-payment request amount), and if the difference is a positive integer, stores the difference in the RAM 203 as a change amount. Next, the CPU 201 notifies the change machine 210 of the change amount. Receiving the change amount notice, the change machine 210 withdraws the change amount and discharges it to the outlet. Then, the change machine 210 supplies a change notification of the change process to the CPU 201. Next, the CPU 201 causes the display unit 205 to display a settlement completion menu including the payment request amount, the deposit amount, and the change amount stored in the RAM 203 as display items. Finally, the CPU 201 stores the transaction identification information read in the process of step S101 in the RAM 203 as the account identification information that has been settled, and ends the process of this flowchart.

  As described above, according to the present embodiment, when the accounting identification information of the read two-dimensional code C1 is already settled in the settlement apparatus 20, the two-dimensional code C1 is read and discarded. Can prevent and prevent fraud. At this time, since the settlement apparatus 20 does not generate an error, the clerk does not need to perform an error canceling operation, and the shopper can smoothly proceed with the settlement process.

  The handy terminal includes a bar code reader that reads a bar code and extracts information recorded in the bar code, and a printer that prints and outputs the payment receipt 40. When the bar code attached, pasted, or printed on the shopper's purchased product is positioned so as to be readable in the bar code reading area of the bar code reader, the handy terminal reads the bar code. The product identification information recorded in the bar code is extracted and registered (stored). The handy terminal generates two-dimensional code record information including the transaction identification information and the merchandise identification information of the registered purchased product when the print button provided in the handy terminal is operated, and the generated two-dimensional code record The information is converted into a two-dimensional code and printed on the payment receipt 40.

  The shopper goes to the registration settlement apparatus operated by the operator with the output settlement receipt 40, and gives the settlement receipt 40 to the operator. The operator positions the two-dimensional code C1 of the payment receipt 40 in the two-dimensional code readable area of the two-dimensional code reader provided in the registered payment apparatus. The registered settlement apparatus is a general POS register, and includes a two-dimensional code reader that reads a two-dimensional code and extracts two-dimensional code recording information recorded in the two-dimensional code, and a barcode reader. When the two-dimensional code C1 of the payment receipt 40 is positioned in the two-dimensional code readable area, the registered settlement apparatus reads the two-dimensional code and extracts the two-dimensional code record information. Then, the registration settlement apparatus determines whether or not the transaction identification information included in the two-dimensional code record information matches the stored transaction identification information. The registered settlement apparatus discards the extracted two-dimensional code record information without displaying an error when the transaction identification information included in the two-dimensional code record information matches the settled transaction identification information. On the other hand, if the accounting identification information included in the two-dimensional code recording information does not match the accounting identification information that has already been settled, the registration settlement apparatus sets the commodity identification information included in the extracted two-dimensional code recording information as one accounting, Registration process and checkout process. For example, when the barcode attached to, pasted on, or printed on the purchase product of the shopper C is read by the barcode reader, the registration settlement apparatus (registration means) uses the product identification information recorded on the barcode for the accounting. Register additional. Further, when the subtotal key provided in the registration settlement apparatus is pressed, the registration settlement apparatus starts the settlement process for the accounting.

In the case of the present embodiment, since the settled medium 40 remains in the scanner unit 204 and can be settled, the scanner unit 204 may continue reading indefinitely. In this case, although the problem due to double reading does not occur, the burden on the scanner unit 204 continues to be applied.
Therefore, when the CPU 201 determines that the medium 40 read by the scanner unit 204 has already been settled, a message indicating that the medium remains in the scanner unit 204 without causing an error, for example, “remains in the scanner unit”. "Please take the ticket you have" may be displayed on the display unit 205.
By doing in this way, the checkout device 20 is a medium that remains in the scanner unit 204 when the clerk who passes near the checkout device 20 or a customer who wants to checkout reads the message while the shopper can checkout. 40, the possibility of removing the medium 40 from the scanner unit 204 is increased. Therefore, the burden on the scanner unit 204 can be reduced.

  The program for realizing the checkout system described above is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into the computer system and executed, thereby executing the execution process. You may go. Here, the “computer system” may include an OS and hardware such as peripheral devices.

  Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used. The “computer-readable recording medium” means a flexible disk, a magneto-optical disk, a ROM, a writable nonvolatile memory such as a flash memory, a portable medium such as a CD-ROM, a hard disk built in a computer system, etc. This is a storage device.

Further, the “computer-readable recording medium” refers to a volatile memory (for example, DRAM (Dynamic) in a computer system serving as a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. Random Access Memory)) that holds a program for a certain period of time is also included.
The program may be transmitted from a computer system storing the program 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 the 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.
The program may be for realizing a part of the functions described above.
Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
