A receipt issuing port 9 for discharging a receipt issued from a printer 11 (see FIG. 2) built in the main body 4 is provided on the left rear side of the main body 4. Further, the POS terminal 1 is connected to a wireless tag reader / writer 12 that reads and writes data from and to the wireless tag 100 (see FIG. 2) attached to each product.

  The keyboard 5 is provided with numeric keys, subtotal keys, clear keys, fastening keys, return keys, and the like. The return key is a key for declaring to set the operation mode to the return mode by being operated.

  Such an electrical system of the POS terminal 1 is configured as shown in FIG. The POS terminal 1 includes a central processing unit (CPU) that centrally controls each unit, a read only memory (ROM) that stores computer programs, and a random access memory (RAM) that functions as a work area that stores various data in a rewritable manner. ), A control unit 21 configured by a timer or the like for measuring the date and time is provided.

  The control unit 21 includes, via the bus 22 and the I / O control unit 23, the drawer 3, the keyboard 5, the mode change switch 6, the cashier and customer displays 7, 8, the printer 11, the wireless tag reader. In addition to the writer 12, a non-volatile memory 24 as a storage unit is connected.

  When the wireless tag 100 attached to a product is brought close to the wireless tag reader / writer 12, the wireless tag reader / writer 12 reads data stored in the wireless tag 100 and inputs the read data to the control unit 21. In addition, the control unit 21 drives and controls the wireless tag 100 to write data. The keyboard 5 inputs a signal corresponding to the operated key to the control unit 21. The mode switch 6 inputs a signal corresponding to the switching position to the control unit 21.

  The nonvolatile memory 24 is provided with a product master file F1, a journal file F2, and a store code table T1. The product master file F1 is a file that stores a product name, a unit price, and the like in association with each product code of the product. The journal file F2 is a file that stores journal data (sales details, sales amount, etc.) that is transaction data based on sales registration processing in association with a transaction number that identifies a transaction for each transaction. The own store code table T1 is a table in which store codes of the own store are stored in advance. The store code is data for specifying a store.

  Next, the wireless tag 100 attached to each product will be described. As shown in FIG. 2, the wireless tag 100 has a known configuration including an IC chip 101 having a CPU (Central Processing Unit) and a nonvolatile memory, and a coil antenna 102, and generates an induced electromotive force in the coil antenna 102. By doing so, it is possible to read / write data from / to the nonvolatile memory of the IC chip 101. The non-volatile memory of the IC chip 101 is provided with a single product data table T2 shown in FIG.

  In the single item data table T2, a tag ID region 103 for storing a tag ID which is transaction specific data, a product code region 104 for storing a product code, a store code region 105 for storing a store code, and a sales for storing a sale date of the product. A day area 106 and a sales amount area 107 for storing the sales amount are provided. Of these data, the tag ID and the product code are stored in advance. The tag ID is data for specifying the wireless tag 100. As will be described in detail later, when a product is sold, the store code that sold the product is written in the store code area 105. This writing indicates that the product is sold and accounted for at the store with the store code. Therefore, whether or not the product has been accounted for can be determined based on whether or not the store code is written in the store code area 105. Thus, in the present embodiment, the store code also serves as sales store specifying data for specifying the store where the product is sold.

  Next, various processes executed by the control unit 21 of the POS terminal 1 will be described. First, in the mode setting process, the operation mode is set to a registration mode, a setting mode, a settlement mode, or the like according to the switching position of the mode change switch 6, and when the operation mode is set to the registration mode, the keyboard 5 By operating the return key, the operation mode is set to the return mode.

  Next, a sales process executed when a product that is a part of a process of product data for which a product to be sold is input will be described with reference to a flowchart shown in FIG. This sales process is executed when the operation mode is the registration mode.

  If the wireless tag 100 attached to the product is brought close to the wireless tag reader / writer 12 and the data stored in the wireless tag 100 is read and input by the wireless tag reader / writer 12 (Y in step S1), the input wireless tag 100 is input. The single product data table T2 is taken into the RAM of the control unit 21 from the data (step S2).

  Then, sales registration processing is executed (step S3). Specifically, the product master file F1 stored in the nonvolatile memory 24 is searched based on the product code stored in the product code area 104 of the single product data table T2, and the product name corresponding to the corresponding product code. And the unit price are registered, and sales are registered based on the product code, the tag ID of the wireless tag 100 attached to the product, the read product name, unit price, and the like. At this time, the product name, unit price, and the like are displayed on the display units 7 and 8.

  Then, the wireless tag reader / writer 12 is used to update the data in the single item data table T2 of the wireless tag 100 (step S4, writing means). Specifically, the store code of the store stored in advance in the store code table T1 is written in the store code area 105, and today's date is written in the sale date area 106. These processes are executed for all products. That is, the process is executed until the tightening key is operated and the tightening process is declared (Y in step S5).

  If the tightening process is declared (Y in step S5), the tightening process is executed (step S6). The closing process calculates the total sales amount and the like, and after issuing the receipt (transaction details) by the printer 11 and opening the drawer 2 of the drawer 3, the journal data (sales details etc.) is stored in the journal file F2. And so on. The journal data of the present embodiment also stores the tag ID of the wireless tag 100 attached to the product corresponding to the product code of the purchased product.

  Next, the flow of the return acceptance process when the customer who purchased the product wishes to return the product will be described based on the flowchart shown in FIG. This return acceptance process is executed in the return mode.

  When the wireless tag 100 attached to the product is brought close to the wireless tag reader / writer 12 and the data stored in the wireless tag 100 is read by the wireless tag reader / writer 12 (Y in step S11), the input wireless tag The single item data table T2 is fetched from the 100 data into the RAM of the control unit 21 (step S12, acquisition means).

  Then, it is determined whether or not the store code stored in the store code area 105 of the single item data table T2 is the store code of the own store (step S13). This determination is executed by comparing the store mode stored in the store code area 105 with the store code of the store stored in the store code table T1. If it is the own store code (Y in step S14), it is next determined whether or not the return available time limit has passed (step S15). The return period is after a specified period (for example, 7 days) from the sales date. Therefore, the determination as to whether or not the returnable deadline has passed is made based on whether the current date on which the processing is being executed is from a sales date stored in the sales date area 106 of the single item data table T2 for a specified period (this implementation In the embodiment, it is determined whether or not 7 days have passed. Here, the function of the determination means is executed in steps S13 and S15. If the returnable deadline has not passed (N in step S16), the return process is accepted and the return process is executed (step S17).

  In the return processing, for example, the product master file F1 stored in the nonvolatile memory 24 is searched based on the product code included in the single product data table T2, and the product name corresponding to the corresponding product code is read. Return registration is performed based on the product code, the read product name, the sales amount stored in the sales amount area 107 of the single item data table T2, and the like. At this time, the sales amount stored in the sales amount area 107 of the single item data table T2 is displayed on the display units 7 and 8, and the drawer 2 of the drawer 3 is opened. Further, based on the tag ID which is the transaction specifying data in the single item data table T2, the transaction data of the product stored in the journal file F2 is searched, and the search result is stored in the nonvolatile memory 24. Here, the function of the returned goods accepting means is executed in step S17.

  Then, the data of the wireless tag 100 is updated using the wireless tag reader / writer 12 (step S18). Specifically, the data in the store code area 105 and the sales date area 106 of the single item data table T2 of the wireless tag 100 attached to the product is deleted.

  When it is determined in step S13 that the store code stored in the store code area 105 of the single item data table T2 is not the store code of the own store or the store code is not stored in the store code region 105 of the single item data table T2. (N in Step S14) and if it is determined in Step S15 that the return period for the product has passed (Y in Step S16), the return of the product is not accepted, so the return is accepted as an error process. The fact that there is no data is displayed on the display units 7 and 8 (step S19), and the process is terminated.

  As described above, in the present embodiment, since the condition for accepting the return is a product that has not passed the return available deadline among the products sold at the store, accepting the return of the product that has passed the return available deadline. It can be lost.

  The sales registration process includes a process of storing transaction data of the product registered for sales in the non-volatile memory 24 that is a storage unit for each transaction, and the reading unit stores the transaction data stored in the wireless tag 100 for specifying the transaction data. By reading the tag ID, which is transaction specific data, and searching the transaction data of the product stored in the non-volatile memory 24 based on the read tag ID, for example, return registration data and transaction data are obtained. A process of associating and outputting a slip can be easily executed.

  As described above, in the present embodiment, when the operation mode is set to the registration mode, the writing unit transmits the store identification data to the wireless tag 100 attached to the product as a wireless tag reader along with the processing of the product data. By writing using the writer 12, sales store specific data can be efficiently written at the time of sale of the product.

  In this embodiment, the return date limit specifying data for specifying the return date limit of the product is described by taking the sale date of the product as an example, but the return date limit data is not limited to this. For example, it may be the returnable deadline itself.

  Moreover, although the store code written in the single item data table T2 of the wireless tag 100 has been described as an example of the store store specifying data for specifying the store that sold the product, the present invention is not limited to this. The wireless tag 100 may be stored in advance. Specifically, the store code may be input in advance in the store code area 105 when the product is delivered. In this case, it is only necessary to indicate that the product has been registered by the sales registration process by inputting the returnable deadline to the wireless tag 100. At this time, registration status data indicating whether or not the product has been registered by the sales registration process may be stored in the single item data table T2 of the wireless tag 100.

  In addition, although the tag ID of the wireless tag 100 attached to the product as transaction specifying data for specifying a transaction has been described as an example, the transaction specifying data is not limited to this, for example, a receipt number (transaction number) or a MAC It may be an address.

  In addition, the same store code is adopted for all stores in the chain store, so that the entire chain store can be handled as one store.

  In the present embodiment, the example in which switching to the return mode is performed by operating the return key has been described. However, the present invention is not limited to this, and switching to the return mode is performed by operating the mode switch 6. May be.

  In the present embodiment, an example in which the return process is executed in the return mode has been described. However, the present invention is not limited to this, and the return process may be executed in the registration mode.

FIG. 6 is a flowchart showing the flow of returned goods data display processing of the present embodiment. In addition, the same part as 1st embodiment is shown with the same code | symbol, and description is also abbreviate | omitted.

  In the present embodiment, as a process to be executed when a customer who has purchased a product wishes to return the product, the returned product data display process is executed instead of the return acceptance process of the first embodiment. It differs from the embodiment.

  As shown in FIG. 6, in the returned merchandise data display process, the wireless tag 100 attached to the product is brought close to the wireless tag reader / writer 12, and the wireless tag reader / writer 12 reads and inputs data stored in the wireless tag 100. If so (Y in step S21), the single item data table T2 is taken into the RAM of the control unit 21 from the input data of the wireless tag 100 (step S22, acquisition means). Then, the store code stored in the single item data table T2 and the sales date and time are displayed on the display units 7 and 8 (step S23, display means). At this time, when the store code is the store code of the own store stored in the own store code table T1, the store code may be displayed instead of the store code. When the store code and the sales date / time are not stored in the single item data table T2, a comment indicating that there is no store code and sales date / time data is displayed.

  As described above, in the present embodiment, when the store code and the sales date / time are stored in the wireless tag 100 attached to the return desired product, the store code and the sales date / time are displayed on the display units 7 and 8. Therefore, the cashier can determine whether or not to accept a return based on the displayed data, thereby eliminating the acceptance of the return of a product whose returnable term has passed.
