The shop server 3 also acquires a list of products for checkout and a product list indicating the user code from the product data processing device 4 . The store server 3 performs checkout processing based on the product list obtained from the product data processing device 4 and the user database. Specifically, the store server 3 calculates the payment amount based on the product list, acquires payment information associated with the user code included in the product list from the user database, Payment is made based on the information and the payment amount. The product data processing device 4 may calculate the settlement amount based on the product list. In this case, the product data processing device 4 adds the calculated settlement amount to the product list and supplies the product list to the store server 3 .

Next, the configuration of the product data processing device 4 will be described.
The product data processing device 4 is a device (product data processing device) that generates a product list. The product data processing device 4 is attached to a cart 13 provided with a basket (container) 11 for storing products and an RFID reader 12 . The product data processing device 4 is configured as a cart-type product data processing device by being attached to a cart 13 having a basket 11 and an RFID reader 12 .

The RFID reader 12 is a wireless tag reader that communicates with an RFID tag (wireless tag) provided on a product by outputting radio waves. RFID reader 12 includes an antenna and signal processing circuitry. The antenna of the RFID reader 12 is an antenna that transmits and receives radio waves. The antenna is configured such that the resonance frequency matches the frequency (for example, UHF band) corresponding to the RFID tag provided on the product. The signal processing circuit processes signals sent to the antenna. A range in which the RFID reader 12 can communicate with the RFID tag is called a communication range.

FIG. 3 is an explanatory diagram for explaining the communication range of the RFID reader 12. As shown in FIG.
As shown in FIG. 3, RFID reader 12 is configured such that its communication range covers the opening of basket 11 .

The RFID reader 12 supplies the tag information acquired from the RFID tag and the generated radio wave change information to the product data processing device 4 via the communication interface.

(First embodiment)
Next, operation of the product data processing device 4 according to the first embodiment will be described.
FIG. 4 is an explanatory diagram for explaining the process of generating a product list by the product data processing device 4 and the accounting process. The processor 25 of the control unit 23 of the product data processing device 4 executes a program stored in the memory 26 to generate a product list.

First, the processor 25 recognizes the user of the product data processing device 4 (ACT11). For example, the processor 25 acquires a user code from the user and transmits it to the store server 3 . The store server 3 refers to the user database, searches for the user corresponding to the received user code, and transmits the search result to the product data processing device 4 . Thereby, the processor 25 of the product data processing device 4 identifies the user operating the product data processing device 4 . The processor 25 acquires the user code based on the user's input to the touch panel 24, for example. Moreover, the product data processing device 4 may be configured to include a camera or scanner for reading the user code. Further, the product data processing device 4 may be configured to include a camera for acquiring a user's face image, and use the acquired face image instead of the user code.

Furthermore, the processor 25 of the product data processing device 4 generates a product list including (or associated with) the user code, and stores the product list in the memory 26 . At this point, the product list is blank. The product list is configured so that tag information obtained from the RFID tag of the product can be entered. Moreover, the processor 25 may display a list of products on the display based on the tag information entered in the product list. For example, the processor 25 may display a list of product names and prices on the display based on the product database on the store server 3 or the product database previously acquired from the store server 3 and tag information.

Processor 25 activates RFID reader 12 connected to second communication interface 22 (ACT 12). As a result, the RFID reader 12 is put into a state of outputting radio waves within the communication range. The RFID reader 12 acquires tag information from the RFID tag and supplies it to the product data processing device 4 when the RFID tag comes within the communication range. Further, the RFID reader 12 generates radio wave change information based on radio waves from the RFID tag and supplies the radio wave change information to the product data processing device 4 . The RFID reader 12 associates the tag information of the RFID tag with the radio wave change information and supplies them to the product data processing device 4 .

The processor 25 of the product data processing device 4 determines whether tag information has been supplied from the RFID reader 12 (ACT 13). When the processor 25 determines that the tag information has not been supplied from the RFID reader 12 (ACT13, NO), it proceeds to the processing of ACT19, which will be described later.

When the processor 25 determines that the tag information has been supplied from the RFID reader 12 (ACT 13, YES), it analyzes the radio wave change information (ACT 14). By analyzing the radio wave change information, the processor 25 determines a change in the positional relationship between the RFID reader 12 and the RFID tag provided on the product. As described above, the radio waves received by the RFID reader 12 from the RFID tag change according to changes in the positional relationship (for example, the distance) between the RFID tag and the RFID reader 12 . Therefore, the processor 25 can determine changes in the positional relationship between the RFID tag and the RFID reader 12 over time based on the radio wave change information.

The strength of radio waves received by the RFID reader 12 from the RFID tag varies according to the distance between the RFID reader 12 and the RFID tag. For example, the processor 25 determines the change in the distance between the RFID reader 12 and the RFID tag based on the change over time in the intensity of radio waves received by the RFID reader 12 from the RFID tag.

Also, for example, the phase of the radio wave received by the RFID reader 12 from the RFID tag changes according to the change in the distance between the RFID reader 12 and the RFID tag. The processor 25 may be configured to determine a change in the distance between the RFID reader 12 and the RFID tag based on a change over time in the phase of radio waves received by the RFID reader 12 from the RFID tag.

Further, for example, the processor 25 detects the RFID reader 12 and the RFID tag based on both the change in the intensity of the radio wave received by the RFID reader 12 from the RFID tag and the change in the phase of the radio wave received by the RFID reader 12 from the RFID tag. It may be configured to determine a change in the distance to the tag.

The RFID reader 12 does not generate the radio wave change information, but sequentially supplies the strength and phase of radio waves received from the RFID tag to the product data processing device 4, and the processor 25 of the product data processing device 4 , the radio wave change information may be generated based on the information from the RFID reader 12 .

The processor 25 determines whether or not there is an RFID tag approaching the RFID reader 12 based on the determination result of the change in the positional relationship between the RFID reader 12 and the RFID tag provided on the product (ACT 15). . When the processor 25 determines that there is no RFID tag approaching the RFID reader 12 (ACT15, NO), the processing proceeds to ACT19, which will be described later.

When the processor 25 determines that there is an RFID tag approaching the RFID reader 12 (ACT15, YES), whether or not the tag information of the RFID tag approaching the RFID reader 12 is entered in the product list. Make a decision (ACT 16). The processor 25 compares the tag information registered in the product list with the tag information of the RFID tag approaching the RFID reader 12, and determines whether or not the same tag information exists in the product list.

When the processor 25 determines that the tag information of the RFID tag approached to the RFID reader 12 is not input to the product list (ACT16, NO), the RFID tag approached to the RFID reader 12 of the product list is Input the tag information (ACT17), and proceed to the processing of ACT19. If the tag information of the RFID tag approaching the RFID reader 12 is not entered in the product list, the processor 25 detects that the RFID tag of the product has approached the RFID reader 12 because the product has been placed in the basket 11 . I judge. Therefore, the processor 25 newly inputs tag information to the product list.

If the processor 25 determines that the tag information of the RFID tag approached to the RFID reader 12 is entered in the product list (ACT16, YES), the tag of the RFID tag approached to the RFID reader 12 The information is erased from the product list (ACT18), and the processing of ACT19 is started. If the tag information of the RFID tag approaching the RFID reader 12 is input to the product list, the processor 25 detects that the RFID tag of the product has approached the RFID reader 12 because the product has been taken out of the basket 11 . I judge. Therefore, the processor 25 erases the tag information from the product list.

Processor 25 determines whether or not to perform accounting processing (ACT 19). For example, the processor 25 determines whether or not to execute accounting processing based on the user's operation on the touch panel 24 . Also, for example, the processor 25 may be configured to determine whether or not to execute accounting processing based on a signal received via the first communication interface 21 . When the processor 25 determines not to execute accounting processing (ACT19, NO), it proceeds to the processing of ACT13. As a result, the processor 25 repeatedly executes the processing of ACT13 to ACT18 until it determines to execute accounting processing.

If the processor 25 determines to execute the accounting process (ACT19, YES), it executes the accounting process (ACT20) and ends the process. For example, processor 25 transmits a product list including a user code to store server 3 . Upon receiving the product list from the product data processing device 4, the shop server 3 refers to the user database based on the user code of the product list and acquires payment information. Also, the shop server 3 calculates the settlement amount based on the product list. The store server 3 makes a payment based on the payment information and the payment amount. Note that the processor 25 may be configured to calculate the payment amount and add the payment amount to the product list each time the product list is updated in ACT17 or ACT18.

As described above, the product data processing device 4 generates a product list, which is a list of products that have wireless tags and are stored in a predetermined container such as the basket 11 . First, the RFID reader 12 as a wireless tag reader for reading the wireless tag acquires tag information including the identification code of the wireless tag from the wireless tag by communicating with the wireless tag existing near the container. Also, the wireless tag reader generates radio wave change information indicating changes in the radio wave from the wireless tag according to time. The product data processing device 4 has a communication interface, a processor 25 and a memory 26 . The communication interface of the product data processing device 4 acquires from the wireless tag reader tag information including the identification code of the wireless tag of the product and radio wave change information indicating changes in the radio waves from the wireless tag over time. The processor 25 of the product data processing device 4 determines a change in the positional relationship of the wireless tag with respect to the wireless tag reader based on the radio wave change information. The processor 25 determines whether or not to input the tag information acquired from the wireless tag to the product list based on the determination result of the change in the positional relationship of the wireless tag with respect to the wireless tag reader. For example, when the processor 25 determines that the wireless tag has approached the wireless tag reader, it updates the product list using the tag information acquired from the wireless tag.

According to such a configuration, simply acquiring tag information from the wireless tag by the RFID reader 12 does not update the product list. Thereby, the product data processing device 4 can prevent the tag information related to the product from being erroneously input to the product list.

Further, when the processor 25 of the product data processing device 4 determines that the wireless tag has approached the wireless tag reader, it determines whether or not the tag information acquired from the wireless tag is entered in the product list. If the tag information acquired from the wireless tag is not entered in the product list, the processor 25 enters the tag information into the product list. Also, if the tag information acquired from the wireless tag is input to the product list, the processor 25 deletes the tag information from the product list. The processor 25 can determine whether the user is trying to take out the product from the basket 11 or the user is trying to put the product in the basket 11 in determining whether the wireless tag has approached the wireless tag reader. difficult. However, the processor can determine whether the user is trying to take out an item from the basket 11 or put an item into the basket 11 by determining whether the item is entered in the item list. . As a result, it is possible to prevent the product from being erroneously entered into the product list.

(Second embodiment)
Next, operation of the product data processing device 4 according to the second embodiment will be described. Note that the configuration of the product data processing device 4 is the same as that of the first embodiment, so the description is omitted.
FIG. 5 is an explanatory diagram for explaining another example of processing for generating a product list by the product data processing device 4 and accounting processing. The processor 25 of the control unit 23 of the product data processing device 4 executes a program stored in the memory 26 to generate a product list.

First, the processor 25 recognizes the user of the product data processing device (ACT31).

Processor 25 activates RFID reader 12 connected to second communication interface 22 (ACT 32). As a result, the RFID reader 12 is put into a state of outputting radio waves within the communication range. The RFID reader 12 acquires tag information from the RFID tag and supplies it to the product data processing device 4 when the RFID tag comes within the communication range. Further, the RFID reader 12 generates radio wave change information based on radio waves from the RFID tag and supplies the radio wave change information to the product data processing device 4 . The RFID reader 12 associates the tag information of the RFID tag with the radio wave change information and supplies them to the product data processing device 4 .

The processor 25 of the product data processing device 4 determines whether or not the tag information has been supplied from the RFID reader 12 (ACT33). When the processor 25 determines that the tag information has not been supplied from the RFID reader 12 (ACT33, NO), it proceeds to the process of ACT42, which will be described later.

When the processor 25 determines that the tag information has been supplied from the RFID reader 12 (ACT33, YES), it analyzes the radio wave change information (ACT34). By analyzing the radio wave change information, the processor 25 determines a change in the positional relationship between the RFID reader 12 and the RFID tag provided on the product. The processor 25 determines whether or not there is an RFID tag approaching the RFID reader 12 based on the determination result of the change in the positional relationship between the RFID reader 12 and the RFID tag provided on the product (ACT35). . When the processor 25 determines that there is no RFID tag approaching the RFID reader 12 (ACT35, NO), the processor 25 shifts to the process of ACT42, which will be described later.

If the processor 25 determines that there is an RFID tag approaching the RFID reader 12 (ACT35, YES), it determines whether the received signal has changed based on the radio wave change information (ACT36). That is, the processor 25 determines whether or not the radio waves received by the RFID reader 12 from the RFID tag change over time. Accordingly, the processor 25 determines whether the item is within the communication range of the RFID reader 12 and the user is still holding the item. Processor 25 determines that the item is within range of RFID reader 12 and that the user is still holding the item if the received signal is changing.

When the processor 25 determines that the received signal has changed (ACT36, YES), the processor 25 performs the first notification process (ACT37) and shifts to the process of ACT36. That is, the processor 25 repeats the first notification process until the received signal stops changing.

A first notification process is a process in which the processor 25 supplies information to the user of the product data processing device 4 . Specifically, in the first notification process, the processor 25 transmits information for notifying the user that the product exists within the communication range of the RFID reader 12 via the touch panel 24, the speaker (not shown), and the first communication interface. 21 or the second communication interface 22. Furthermore, the processor 25 may cause the display 27 of the touch panel 24 to display the product information of the product for which the received signal is changed.

When the processor 25 determines that the received signal has not changed (ACT36, NO), it performs the first notification process (ACT37), and the tag information of the RFID tag approaching the RFID reader 12 is added to the product list. It is determined whether or not it is input (ACT38). The processor 25 compares the tag information registered in the product list with the tag information of the RFID tag approaching the RFID reader 12, and determines whether or not the same tag information exists in the product list.

If the processor 25 determines that the tag information of the RFID tag approaching the RFID reader 12 is not input to the product list (ACT38, NO), the RFID tag approaching the RFID reader 12 of the product list is Enter the tag information (ACT39), and proceed to the processing of ACT41.

If the processor 25 determines that the tag information of the RFID tag approached to the RFID reader 12 is entered in the product list (ACT38, YES), the tag of the RFID tag approached to the RFID reader 12 The information is erased from the product list (ACT40), and the process proceeds to ACT41.

When the product list is updated in ACT39 or ACT40, the processor 25 performs second notification processing (ACT41).

A second notification process is a process in which the processor 25 supplies information to the user of the product data processing device 4 . Specifically, in the second notification process, the processor 25 transmits information for notifying the user that the product list has been updated via the touch panel 24, a speaker (not shown), the first communication interface 21, or the second communication. This is processing for outputting via the interface 22 . For example, the processor 25 may cause the display 27 of the touch panel 24 to display the updated product list. For example, when tag information is input to the product list in ACT 39 , the processor 25 may cause the display 27 of the touch panel 24 to display product information corresponding to the input tag information. Further, for example, when the tag information is deleted from the product list in ACT 40 , the processor 25 may cause the display 27 of the touch panel 24 to display the product information corresponding to the deleted tag information.

Processor 25 determines whether or not to perform accounting processing (ACT 42). For example, the processor 25 determines whether or not to execute accounting processing based on the user's operation on the touch panel 24 . Also, for example, the processor 25 may be configured to determine whether or not to execute accounting processing based on a signal received via the first communication interface 21 . When the processor 25 determines not to execute accounting processing (ACT42, NO), it proceeds to the processing of ACT33. As a result, the processor 25 repeatedly executes the processing of ACT33 to ACT41 until it determines to execute accounting processing.

If the processor 25 determines to execute the accounting process (ACT42, YES), it executes the accounting process (ACT43) and ends the process. For example, processor 25 transmits a product list including a user code to store server 3 . Upon receiving the product list from the product data processing device 4, the shop server 3 refers to the user database based on the user code of the product list and acquires payment information. Also, the shop server 3 calculates the settlement amount based on the product list. The store server 3 makes a payment based on the payment information and the payment amount. The processor 25 may be configured to calculate the payment amount and add the payment amount to the product list each time the product list is updated in ACT39 or ACT40.

As described above, the processor 25 of the product data processing device 4 determines whether or not the radio wave (reception signal) received by the RFID reader 12 from the RFID tag has changed, based on the radio wave change information. Processor 25 determines that the item is within range of RFID reader 12 and that the user is still holding the item if the received signal is changing. Also, the processor 25 determines that the user has put the product in the basket 11 or taken out the product from the basket 11 when the received signal stops changing. When the received signal stops changing, the processor 25 updates (inputs or deletes) the product list using the tag information acquired from the RFID tag of the product.

According to such a configuration, simply acquiring tag information from the wireless tag by the RFID reader 12 does not update the product list. Thereby, the product data processing device 4 can prevent the tag information related to the product from being erroneously input to the product list.
