Description

  Embodiments of the present invention relate to a commodity data processing apparatus and a commodity data processing program.

  Checkout systems are installed in stores such as supermarkets. The checkout system is provided with a product data processing apparatus that registers a product that a customer intends to purchase, generates transaction information, and performs a payment process based on the transaction information. Usually, in the commodity data processing apparatus, operations for registration and settlement processing of the commodity are performed by the operation of a store clerk (cash shop). Generally, registration of a product is performed by causing a scanner to read a barcode attached to the product.

  In recent years, for example, a checkout system capable of registering a product using an electronic tag called an RFID (radio frequency identification) tag has been increasing. In this checkout system, an RFID tag in which product-specific data is recorded is attached to each product, and data stored in the RFID tag (hereinafter referred to as tag data) is read by a tag reader using wireless communication or the like. The product data processing apparatus collects information on a product to be purchased based on the tag data to generate transaction information.

  Since the reading by the tag reader is performed by wireless communication (radio wave), a reader formed by, for example, a member that shields radio wave so that tag data can be read only from the RFID tag attached to the product to be purchased Execute for the goods stored in the case of

  Since registration of a product using an RFID tag can be performed collectively for a plurality of products, processing for product registration can be streamlined. On the other hand, as described above, since it is necessary to store the product in the housing of the reader and execute reading, when the product stored in the housing is read, the product is taken out. Forgetting can occur. For example, when goods are piled up in the goods basket, when taking out the goods basket from the reading apparatus, the goods fall from the goods basket or the reading apparatus in a state where several items are not put in the goods basket In the case of being accommodated in the case of, the situation of forgetting to take out goods etc. may occur.

Although not shown, a speaker capable of outputting a sound such as a warning sound or a voice message is provided.

  The CPU 10 controls each unit to realize various operations as the POS terminal 2 based on a control program including an operating system, middleware, an application program and the like stored in the ROM 11 and the auxiliary storage unit 13. The CPU 10 executes a control program to store tag data (such as a product code) read from an RFID tag attached to a product through the reader 1 (tag reader 26) in the RAM 12 (tag list area 12a) Execute registration processing for generating transaction information used for settlement processing based on tag data (product code etc.), and settlement processing based on the transaction information. Furthermore, the CPU 10 executes the control program to cause the tag reader 26 to execute the first reading operation, and after the settlement process based on the tag data read by the first reading operation is executed, The read control function for executing the second read operation, the output control function for outputting a message when the tag data is read by the second read operation, and the completion of the work for taking out the product from the reader 1 are determined. The discrimination function is realized.

  The ROM 11 stores an operating system and the like. The ROM 11 may store middleware and application programs. The ROM 11 may also store data to be referred to when the CPU 10 performs various processes.

  The RAM 12 stores data to be referred to when the CPU 10 performs various processes. Further, the RAM 12 is used as a so-called work area in which data temporarily used when the CPU 10 performs various processing is stored. A part of the storage area of the RAM 12 is used as, for example, a tag list area 12a and a product list area. The tag list area 12 a stores tag data read from an RFID tag attached to a product by the tag reader 26 of the reader 1.

The auxiliary storage unit 13 is, for example, a hard disk drive or a solid state drive (SSD), and stores data used when the CPU 10 performs various processes, and data generated by the process of the CPU 10. The auxiliary storage unit 13 may also store middleware or an application program.
The clock unit 14 performs clocking operation on a steady basis, and generates date and time information representing date and time.

  The touch panel controller 16 controls an operation for displaying an image on the touch panel 22 under the control of the CPU 10. Further, the touch panel controller 16 provides the CPU 10 with information output by the touch panel 22 according to a user operation on the touch panel 22 via, for example, the RAM 12.

The card reader 23 reads card information recorded in a card inserted from the card insertion slot. The card may include a payment card such as a credit card, a debit card and a prepaid card, or a point card. Moreover, the card reader 23 may have a function of writing information on a card.

The tag reader 26 may be of known construction including an antenna, transmitter circuitry and receiver circuitry. The tag reader 26 takes a tag reading room (storage room) space as a reading range, and reads tag data from an RFID tag present in the space.
The open / close sensor 27 detects the open / close state of the open / close lid 1 b of the reader 1 and notifies the CPU 10 of the open / close state.
The communication device 20 communicates with another device such as a server (not shown) via a communication network 200 such as a LAN (local area network) or the Internet.

Next, the operation of the commodity data processing apparatus (POS terminal 2) in the present embodiment will be described.
3 and 4 are flowcharts of control processing by the POS terminal 2 (CPU 10) in the present embodiment. The CPU 10 executes the control processing shown in FIGS. 3 and 4 in accordance with the control program stored in the ROM 11 or the auxiliary storage unit 13. The contents of the processes described below are merely examples, and various processes that can obtain similar results can be appropriately used.

  When the POS terminal 2 is activated in response to the power switch (not shown) turned on by the operator or the like, the CPU 10 starts the execution of the control program and starts the control process shown in FIGS.

  The CPU 10 executes an initialization process for initializing each unit constituting the commodity data processing apparatus 100 (Act 1). For example, the initialization process includes a process of clearing the tag list area 12 a and the product list area set in the RAM 12. The initialization includes a process of causing the touch panel 22 to display a screen (operation screen) for receiving an input operation for the checkout process.

  After the initialization is completed, the CPU 10 confirms whether the start of the checkout procedure has been requested by a predetermined operation such as touching a scan button provided on the operation screen, for example. When the start of the procedure is not requested (Act 2, No), the CPU 10 waits for the request of the start of the procedure.

  The operator usually stores the goods to be purchased by the customer in the tag reading chamber of the reading device 1 before the operation requiring the start of the procedure. That is, the operator opens the open / close lid 1 b of the reader 1 and stores the open / close lid 1 b in the tag reading chamber through the opening, and then closes the open / close lid 1 b. In this case, as shown in FIG. 1, the shopping baskets 6 and 7 may be stored in the tag reading room with the products placed in the shopping baskets 6 and 7, or even if only the goods are stored in the tag reading room good. Generally, when there are a large number of products to be purchased, the customer puts the products in the shopping basket 6 and brings it to the accounting counter 3. In this case, the product may be stored in the tag reading room with the product put in the shopping basket 6. On the other hand, the customer may bring only the product to the accounting counter 3 when the number of products to be purchased is small and the product can be held by hand. In such a case, the operator may put the product in a separately prepared shopping basket and store it in the tag reading room, or may save the time and effort of preparing the shopping basket and store only the product in the tag reading room.

  When the CPU 10 detects that a predetermined operation for requesting the start of the procedure has been performed (Act 2; Yes), the CPU 10 activates a reading operation by the tag reader 26 (Act 3). The tag reader 26 outputs radio waves to the tag reading room space to read tag data from an RFID tag present in the tag reading room space. Here, when the tag data is read from the RFID tag (Act 4, Yes), the tag reader 26 notifies the CPU 10. When a plurality of RFID tags (goods) exist in the tag reading room, the tag reader 26 reads tag data from the RFID tag one by one according to a known procedure, for example, and sequentially notifies the CPU 10.

  The CPU 10 is an RFID tag (hereinafter referred to as a product tag) in which tag data (hereinafter referred to as received tag data) read by the tag reader 26 is attached to a product sold in the store where the POS terminal 2 is installed. To see if it is When the CPU 10 confirms that the received tag data is not that of a product tag (Act 5, No), the CPU 10 follows the received tag data as tag data read from an RFID tag attached to a product not to be sold. Do not execute processing, and return to reading about another RFID tag (Act 4).

  On the other hand, when the CPU 10 confirms that the received tag data is that of a product tag (Act 5, Yes), the CPU 10 searches the tag list area 12a using the tag code included in the received tag data as a key (Act 6).

  When the same tag code as the tag code included in the received tag data is not found from the tag list area 12a (No in Act 7), the CPU 10 adds the received tag data to the tag list area 12a and writes it (Act 8). The CPU 10 acquires product information (a product name, a price, etc.) based on the product code included in the received tag data (Act 9). For example, the CPU 10 may read product information corresponding to the product code stored in the auxiliary storage unit 13 or may receive distribution of product information from a store server or the like via the communication network 200. The CPU 10 adds (updates) the product information acquired based on the received tag data to the product list stored in the product list area of the RAM 12 (Act 10).

  After updating the product list, the CPU 10 updates the sub-planning surface displayed on the touch panel 22 so as to indicate the content of the updated product list (Act 11). The sub-planning surface is a screen for displaying a list of commodity names and prices of commodities identified based on the read tag data and displaying a subtotal amount. On the sub-planning side, a settlement button is also provided to request the start of settlement.

  Hereinafter, as described above, the processing according to the received tag data read by the tag reader 26 is repeatedly executed (Acts 4 to 11).

  When the tag code included in the received tag data read by the tag reader 26 is only the same code as the already read tag code stored in the tag list area 12a, the CPU 10 exists in the tag reading room of the reading device 1 Since reading of tag data has been completed from all of the RFID tags, the display of the sub-planning surface is not updated.

  The operator can confirm that the reading of the tag data is completed because the display on the sub-planning surface is not updated (the product is added). Here, the operator can instruct execution of the settlement process by touching the settlement button displayed on the minor planning surface. The CPU 10 detects a touch on the settlement button, and ends the reading operation of the reading device 1.

  When the touch operation on the settlement button is detected on the touch panel 22 (Act12, Yes), the CPU 10 executes the settlement process based on the product information stored in the product list. In the settlement process, for example, the purchase object is selected according to the selection of the payment method (cash, credit card) and the payment operation according to the payment method (cash input to the automatic change machine 5, reading of the credit card by the card reader 23). Settlement is performed for the goods to be

  The CPU 10 causes the touch panel 22 to display a settlement completion screen on which the settlement process is completed (Act 14). In addition, the CPU 10 starts measuring the elapsed time after the end of the settlement process (or after displaying the settlement end screen).

  The CPU 10 causes the printer 24 to issue a receipt representing the result of the settlement process (Act 15). That is, the CPU 10 generates a receipt image representing the item name, the amount, etc. which is the object of the payment processing, the total amount settled, the deposit amount, the change amount, etc. Print it. The area on which the receipt image of the receipt paper is printed is separated from the other areas and then discharged from the receipt issue port 5. When the credit payment is performed, the CPU 10 controls the printer 24 to issue a receipt as the certificate. As a result, a receipt using receipt paper is issued to the customer. Alternatively, the CPU 10 generates receipt data including the information described in the receipt, and sends the receipt data to, for example, a center server (not shown) via the communication network 200. The customer can access the center server using an appropriate information communication terminal and browse the contents of the receipt data.

  Further, the CPU 10 confirms whether or not change has occurred as a result of the settlement process. When the change is generated (Act 16, Yes), the CPU 10 causes the automatic change machine 5 to pay out the change (Act 17).

  On the other hand, the CPU 10 activates the reading operation by the tag reader 26 when the elapsed time after the end of the settlement process (or after the settlement completion screen is displayed) reaches a preset time (for example, 8 seconds). Then, the tag reading chamber of the reading device 1 executes the second reading operation for detecting a forgotten product (Act 18). The time set in advance is, for example, a time when the operator can take out the product from the reading apparatus 1 by a normal operation after the settlement process is completed, and the customer who has completed the settlement process is far away from the POS terminal 2 The appropriate time is set to the extent that it does not speak.

  When the tag data is not read by the reading operation by the tag reader 26 again (Act 19, No), the CPU 10 initializes it as processing for the next customer as all items being taken out from the reading device 1 Execute the process (Act 1).

  On the other hand, when the received tag data is read by the reading operation by the tag reader 26 again (Act 19, Yes), the CPU 10 uses the tag code included in the received tag data as a key, and the tag is recorded The list area 12a is searched (Act 7).

  If the CPU 10 finds no tag code identical to the tag code included in the received tag data from the tag list area 12 a by searching the tag list area 12 a (No in Act 21), all items are taken out from the reader 1 In this case, the initialization process is performed to process the next customer (Act 1). That is, the rereading operation described above is performed when the elapsed time after the end of the settlement process (or after the settlement completion screen is displayed) has become a preset time. Therefore, after the product is taken out from the reading device 1, there is a possibility that the reading operation (Act 18) is performed again in a state where the open / close lid 1b is not closed. In this case, the tag reader 26 does not complete the payment processing around the reader 1, for example, a tag from an RFID tag attached to a product not to be purchased by the customer (a product to be purchased by the next customer, etc.) I sometimes read data. Therefore, even if the tag data is read, the process proceeds to the initialization process because it is not forgot the product.

  On the other hand, when the CPU 10 finds a tag code identical to the tag code included in the received tag data from the tag list area 12 a by searching the tag list area 12 a (Act 21, Yes) Display a message warning of forgetting (Act 22). Further, an error sound indicating a warning may be output from a speaker not shown.

  For example, after the end of the settlement process, even if a preset time has passed, if no work has been done to take out the product from the reading device 1, all the items remain in the tag reading chamber of the reading device 1. Yes. Therefore, it is determined that the same tag code as the received tag data is stored in the tag list area 12a.

  In addition, even if it is a case where the product is taken out from the reading device 1 within a preset time after the settlement process is completed, for example, when the product basket in which the products are piled up is taken out from the reading device 1 The goods may fall from the goods basket and be left in the tag reading room. In such a case, a message is output because the received tag data read from the RFID tag attached to the product left in the tag reading room matches the tag data that has been subjected to payment processing. Similarly, when only the goods are accommodated in the reading device 1 without using the goods basket, a message is displayed when all the goods have not been taken out after the settlement process.

FIG. 5 is a view showing an example of the message display screen SC in the present embodiment.
On the message display screen SC shown in FIG. 5, for example, a message 50 of "Please check whether there is a product that you have forgotten to remove" is displayed. In addition, the message display screen SC is provided with a clear button 52 for instructing message deletion.

  By displaying the message display screen on the touch panel 22, the operator is prompted to confirm whether or not the product is left in the tag reading room of the reading device 1. When the touch operation on the clear button 52 of the message display screen SC is detected (Act 23, Yes), the CPU 10 erases the message display screen SC (Act 24), and performs initialization processing to process the next customer. Execute (Act 1). That is, the operator confirms the message display screen SC and can not proceed to processing for the next customer unless the clear button 52 is operated. For this reason, the operator can be assuredly confirmed that the product has been left out.

  In this manner, in the product data processing apparatus 100 (POS terminal 2) according to the present embodiment, even if the product for which the payment processing has been completed is forgotten to be removed from the tag reading room of the reader 1, the product data processing apparatus 100 (POS terminal 2) Can read tag data and output a message. As a result, it is possible to make the operator confirm whether or not the tag reading room of the reader 1 has forgotten to take out the product, and it is possible to reliably prevent the forgetting of the product.

  In the above description, the rereading operation for detecting a product left behind after the settlement process is performed only once (Act 18), but may be performed a plurality of times. For example, when the tag data is read from the RFID tag attached to the item for which the payment processing has been performed by the second reading operation (second time), the message is displayed as described above (Act 22). Then, after a preset time (for example, 5 seconds) elapses after the message is displayed, the tag reader 26 executes the reading operation (third time) again. This makes it possible to reliably check for missing items. In addition, when tag data are read by the reading operation again, you may make it output the message of a different content each time.

  Further, in the above description, when the elapsed time after the end of the settlement process (or after the settlement completion screen is displayed) becomes the time set in advance, the reading operation by the tag reader 26 is executed again. However, the reading operation may be performed again after detecting that the product has been taken out of the reading apparatus 1 after the settlement process. That is, after it is determined that the product is in the state of being out of the reading target by the tag reader 26, the CPU 10 causes the tag reader 26 to execute the reading operation again.

  For example, after the settlement process is completed, the CPU 10 is notified that the open / close lid 1b is opened from the open / close sensor 27 of the reading device 1, and then the open / close lid 1b is closed again from the open / close sensor 27 When it is notified that the product is taken out, it is determined that the product has been taken out.

  Alternatively, after the settlement process is completed, the CPU 10 causes the touch panel 22 to display a confirmation button for the operator to input that the removal of the product from the reading device 1 is completed. After taking out the product from the reading device 1, the operator performs a touch operation on the confirmation button. When the CPU 10 detects a touch operation on the confirmation button, the CPU 10 determines that the product has been taken out.

  The method for detecting that the product has been taken out of the reader 1 (that the product has been excluded from being read by the tag reader 26) may be a method other than the method described above. As described above, when the CPU 10 determines that the product is not to be read by the tag reader 26 as described above, the CPU 10 causes the tag reader 26 to execute the re-reading operation as described above.

  Further, in the above description, the checkout system provided with the product data processing apparatus 100 (POS terminal 2) operated by a store clerk (a cashier) is taken as an example, but the customer mainly performs an operation for settlement processing. It is also possible to apply to a self type or semi self type check system. In the product data processing apparatus provided in either the self-type or semi-self type checkout system, the same operation and effect can be obtained by executing basically the same processing as the processing shown in the flowcharts of FIGS. 3 and 4 described above. You can get For example, after the settlement process is completed, after displaying a message notifying the customer of settlement completion (for example, "Thank you for using"), after a predetermined time (for example, several seconds) elapses, the tag reader 26 rereads Run it. Here, when the tag data is read from the RFID tag attached to the forgotten item in the tag reading room, a message (display or voice) is output to notify the customer of the forgotten item removal. .

  In the above description, the reading device 1 and the POS terminal 2 are configured in separate housings, but it is also possible to configure the product data processing device 100 in which the reading device 1 and the POS terminal 2 are integrated. is there. Further, the shape of the tag reading chamber of the reading device 1 is not limited to the box shape as shown in FIG. 1 and can be configured in any shape and size according to the products handled in the store. Moreover, when the tag data read by the tag reader 26 can be specified only to the tag data read from the RFID tag attached to the item to be purchased by the customer, the tag data stored in the tag reading room of the reader 1 It is not necessary to execute the reading operation by the tag reader 26. For example, it is not necessary to store the product in the tag reading room by adjusting the radio wave transmitted from the tag reader 26 not to reach other than the product to be purchased by the customer.
