[0008] In one aspect of the present disclosure, a recording medium stores a program that causes a computer to execute a process of acquiring signal information from the RFID tag when a gate sensor installed at a gate through which a customer passes reads product identification information in an RFID tag attached to a product, determining the reading accuracy of the product identification information based on the signal information, and if it is determined that the reading accuracy is low, acquiring the storage status of the product and outputting guidance information for re-reading the product identification information based on the storage status.

[0009] According to the present disclosure, it is possible to provide an information processing device that can provide guidance for correctly reading product information of a product to be purchased, regardless of the storage status of the product.

[0011] Hereinafter, with reference to the drawings, embodiments of an information processing device, an information processing system, an information processing method, and a non-transitory recording medium for recording a program according to the present disclosure will be described in detail. The present embodiments do not limit the disclosed technology.

[0012] First Embodiment First, a first embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 1 is a block diagram showing an example of a configuration including an information processing device 100 according to the first embodiment. As shown in Fig. 1, in an information processing system 10, the information processing device 100 is connected to a gate sensor 200 and an output device 300 via a network.

[0013] The information processing device 100 is a device that outputs guidance information to enable a customer shopping at a store to correctly read the product identification information of a product purchased by the customer. The gate sensor 200 is a sensor for reading the product identification information of a product purchased by the customer. The output device 300 is a device that outputs guidance information to enable a customer to correctly read the product identification information, and is, for example, the gate sensor 200 or a display installed near the gate sensor 200, or a display on the customer's terminal. When the output device 300 is a customer's terminal, the guidance information is displayed, for example, on a screen of a shopping application program installed on the terminal. The store is, for example, a retail store that sells clothing, food, etc.

[0014] FIG. 2 is a schematic diagram illustrating an example of a gate in this embodiment. A walk-through gate 91 such as that shown in FIG. 2 is provided, for example, near the exit of a store. In the example shown in FIG. 2, the walk-through gate 91 is configured by providing antennas 202 of gate sensors 200 on both sides of an aisle 96 through which customers pass. Note that, in the configuration example shown in FIG. 2, two gate sensors 200 are provided on each side of the aisle 96, but the number of gate sensors 200 and antennas 202 is not limited to the configuration example shown in FIG. 2. Furthermore, the gate sensors 200 may be provided on only one side of the aisle 96.

[0015] In the example of walk-through gate 91 in Fig. 2, if the reading of the product identification information is successful, a door (not shown) on the exit side of walk-through gate 91 is opened, allowing the customer to exit the store. In addition, an output device 300 (speaker, display, lamp, etc.) (not shown) may be provided at walk-through gate 91, and the product information of the read product identification information may be output by output device 300. Furthermore, if payment information is registered in advance in a shopping application program, the payment process for the product of the read product identification information may be executed using that payment information.

[0016] The gate sensor 200 includes an RFID (Radio Frequency Identification) reader 201 and an antenna 202. The RFID reader 201 is a control circuit that communicates with an RFID tag via the antenna 202 in accordance with a predetermined communication protocol and reads product identification information stored in the RFID tag of a product. The RFID reader 201 outputs the product identification information read from the RFID tag to the information processing device 100. The antenna 202 is installed in a position where it can transmit and receive radio waves to and from an RFID tag passing through the walk-through gate 91, and transmits radio waves to the RFID tag and receives radio waves transmitted from the RFID tag. Note that the antenna 202 may be provided as a separate transmitting antenna and a separate receiving antenna.

[0017] The reading process by the gate sensor 200 has the following characteristics. In the reading process by the gate sensor 200, since multiple products may be stored together in a product storage means such as a shopping cart, the RFID tags of some products may not be read. This occurs, for example, when multiple products are stored overlapping each other in a shopping cart, and the radio waves used for reading are obstructed by products containing metal or liquid. On the other hand, when the gate sensor 200 performs a reading process for one customer, it may also read the RFID tags of other customers.

[0018] Returning to FIG. 1 , the information processing device 100 includes an information acquisition unit 101, a determination unit 102, a storage status acquisition unit 103, and an output unit 104. FIG. 3 is a diagram illustrating an example of a hardware configuration in which the information processing device 100 according to the first embodiment of the present disclosure is realized by a computer device 500 including a processor. As shown in FIG. 3 , the information processing device 100 includes a central processing unit (CPU) 501, memories such as a read-only memory (ROM) 502 and a random access memory (RAM) 503, a storage device 505 such as a hard disk for storing a program 504, a communication interface 508 for network connection, and an input / output interface 509 for inputting and outputting data. In the first embodiment, the information processing device 100 is connected to each component via a bus 510. The information processing device 100 according to the first embodiment shown in FIG. 1 can also be configured using cloud computing or the like.

[0019] The CPU 501 runs an operating system to control the entire information processing device 100 according to the first embodiment of the present invention. The CPU 501 also reads programs and data into memory from a recording medium 506 mounted in, for example, a drive device 507. The CPU 501 also functions as the information acquisition unit 101, determination unit 102, storage status acquisition unit 103, and output unit 104 according to the first embodiment, or as part of these, and executes processing or commands in the flowchart shown in FIG. 7, which will be described later, based on the program.

[0020] The recording medium 506 is, for example, an optical disk, a flexible disk, a magneto-optical disk, an external hard disk, or a semiconductor memory. The semiconductor memory or the like that is part of the recording medium is a non-volatile storage device that stores the program. The program may also be downloaded from an external computer (not shown) that is connected to a communication network.

[0021] As described above, the first embodiment shown in Fig. 1 is realized by the computer hardware shown in Fig. 3. However, the means for realizing each unit included in the information processing device 100 in Fig. 1 is not limited to the configuration described above. Furthermore, the information processing device 100 may be realized by a single physically coupled device, or may be realized by a system consisting of two or more physically separated devices connected by wire or wirelessly.

[0022] The information acquisition unit 101 is a means for acquiring signal information from an RFID tag when the gate sensor 200, which is provided at a gate through which customers pass, reads the commodity identification information stored in the RFID tag attached to the commodity. In this embodiment, the information acquisition unit 101 acquires the signal strength by measuring the RSSI (Received Signal Strength Indicator) value from the RFID tag received by the antenna 202. The information acquisition unit 101 may also acquire the number of times the gate sensor 200 reads each unit of commodity identification information. When there are multiple commodities, the information acquisition unit 101 acquires signal information from the RFID tag of each commodity.

[0023] The determination unit 102 is a means for determining the reading accuracy of the commodity identification information based on signal information. In this embodiment, the determination unit 102 determines the reading accuracy by comparing the signal strength or the number of reads of the read commodity identification information with preset thresholds for those values. The signal strength received by the antenna 202 increases the closer the distance from the antenna. Furthermore, the higher the signal strength from an RFID tag, the more times the commodity identification information is read. On the other hand, when radio wave interference occurs due to overlapping commodities or when an RFID tag outside a gate is read, the signal strength is low and the number of reads is low. Therefore, if the signal strength or the number of reads is higher than the preset threshold, the determination unit 102 determines that the reading accuracy of the commodity identification information is high. On the other hand, if the signal strength or the number of reads is equal to or lower than the preset threshold, the determination unit 102 determines that the reading accuracy of the commodity identification information is low. When multiple pieces of signal information are input from the information acquisition unit 101, the determination unit 102 determines the reading accuracy of each piece of commodity identification information.

[0024] The storage status acquisition unit 103 acquires the storage status of the products when it is determined that the reading accuracy of the product identification information is low. When multiple product identification information has been read and it is determined that the reading accuracy of any of the product identification information is low, the storage status acquisition unit 103 acquires the storage status of the products. The storage status acquisition unit 103 is, for example, configured with a camera, and acquires information on the type of product storage means, such as a shopping basket, a bag carried by a customer, or a shopping bag. When the product storage means is a shopping basket, for example, the storage status acquisition unit 103 may acquire information on the storage status of the products in the product storage means when the storage status can be confirmed from the appearance. The storage status acquisition unit 103 acquires information on the storage status of the products, such as whether multiple products are stacked. The storage status acquisition unit 103 may also acquire, for example, the number of each product identification information read.

[0025] The output unit 104 is a means for outputting guidance information for re-reading the product identification information based on the storage status. The output unit 104 outputs the guidance information for re-reading to the output device 300, for example, based on the type of product storage means used by the customer. The guidance information is, for example, advice to the customer to improve the accuracy of reading the product identification information. Specifically, when the product storage means is a shopping basket, in which the storage position of the products in the product storage means may change, the output unit 104 outputs guidance information for changing the storage position of the products, such as encouraging the customer to shake the products in the shopping basket or changing the order of the products stacked in the shopping basket. In this case, the output unit 104 may output guidance information for changing the storage position of the products in the product storage means only when a predetermined number or more of product identification information has been read. In other words, when the number of read product identification information is less than the predetermined number, guidance information other than changing the storage position of the products, such as changing the orientation of the shopping basket, may be output.

[0026] On the other hand, if the reading accuracy does not change even when the storage position of the product in the product storage means is changed, such as when the product storage means is a customer's bag, the output unit 104 outputs guidance information to move the product storage means closer to the antenna 202 and read again, to change the orientation of the product storage means, to have the customer remove the product from the product storage means, or to guide the customer to another location for reading the product identification information. The output unit 104 may determine the guidance information to output based on the positional relationship between the product storage means and the antenna 202 when the product identification information is read or the reading accuracy of the product identification information. The other location for reading is, for example, a semi-self-service POS (Point of Sale system), a self-service POS, or a loading platform for bagging products.

[0027] 4 and 5 show examples of guidance information for re-reading product identification information by the output unit 104. In the example of Fig. 4, when the product storage means is a shopping basket, information is output encouraging the user to shake the shopping basket. In the example of Fig. 5, when the product storage means is something other than a shopping basket, information is output to guide the user to a self-service POS.

[0028] The output unit 104 may display a list of product information for which product identification information has been read. FIG. 6 is an example of the list of read product information. In this case, the output unit 104 may display the product information in descending order of reading accuracy. The output unit 104 may output a screen for the customer to confirm whether or not they have purchased a product for which the determination unit 102 has determined that the reading accuracy is low. In the example screen of FIG. 6, the customer is asked whether or not they have purchased "Product A," which is a product marked with a "★." The output unit 104 may also display a list of product information such as that shown in FIG. 6 on a semi-self-service POS or the like installed at another location after guiding the customer to another location. Furthermore, if payment information has been registered in advance, the output unit 104 may display the list of product information shown in FIG. 6 on the customer terminal to prompt the customer to confirm the products they wish to purchase before executing the payment process using the pre-registered payment information.

[0029] 7 is a flowchart showing an outline of the operation of the information processing device 100 in the first embodiment. The processing according to this flowchart may be executed based on program control by the processor described above. While this flowchart acquires the type of product storage means as the product storage status, guidance information for re-reading the product identification information may be output based on the product storage status other than the type of product storage means.

[0030] 7 , first, the information acquisition unit 101 acquires signal information from the RFID tag when the gate sensor installed at the gate through which customers pass reads the commodity identification information stored in the RFID tag attached to the commodity (step S101). Next, the determination unit 102 determines the reading accuracy of the commodity identification information based on the signal information (step S102). Next, if the reading accuracy is determined to be low (S103; YES), the storage status acquisition unit 103 acquires the commodity storage status (step S104). On the other hand, if the reading accuracy is determined to be high (S103; NO), the storage status acquisition unit 103 ends the flow.

[0031] Next, if the product storage means is a shopping cart (S105; YES), the output unit 104 outputs guidance information urging the user to change the storage position of the product in the shopping cart (step S106). On the other hand, if the product storage means is not a shopping cart (S105; NO), the output unit 104 outputs guidance information guiding the user to another location for reading the product identification information (step S107). Finally, if the determination unit 102 determines that the reading accuracy is low even after changing the storage position of the product in the shopping cart (S108; YES), the output unit 104 outputs guidance information guiding the user to another location for reading the product identification information (step S109). With this, the information processing device 100 ends information processing.

[0032] 7, if it is determined in S103 that the reading accuracy is low, the storage status acquisition unit 103 may acquire the storage status of the product (step S104), and then proceed to the flow of S107 without making the judgment in S105. Furthermore, in S105, if the product storage means is a shopping cart, the output unit 104 may output guidance information guiding the user to another location for reading the product identification information, rather than guidance information urging the user to change the storage position of the product in the shopping cart. In this case, the flows of S108 and S109 in FIG. 7 are unnecessary.

[0033] In the information processing device 100 of this embodiment, when it is determined that the reading accuracy is low, the output unit 104 outputs guidance information for re-reading the product identification information based on the storage situation. As a result, if the reading accuracy does not improve even after changing the storage position of the product in the product storage means, for example, guidance information for re-reading by another method is output. Therefore, guidance can be provided for correctly reading the product information of the product to be purchased regardless of the storage situation of the product.

[0034] [Modification of First Embodiment] Next, a modification of the first embodiment of the present disclosure will be described in detail with reference to the drawings. This modification differs from the first embodiment in that a time-series change in signal strength is used as signal information received from an RFID tag.

[0035] In this modification, the information acquisition unit 101 acquires time-series changes in signal strength as signal information received from the RFID tag, and the determination unit 102 determines the reading accuracy based on the time-series changes in signal strength. The determination unit 102 uses, for example, time-series changes in RSSI values ​​as the time-series changes in signal strength. FIG. 8 is a graph showing time-series changes in signal strength when passing through a gate in this modification. In this modification, if two gate sensors 200 are provided on the entrance and exit sides of the walk-through gate 91 as in the configuration example shown in FIG. 2 , when a shopper carries a product equipped with an RFID tag and moves through the walk-through gate 91, the RSSI value received by the antenna 202 reaches its maximum when the shopper approaches the antenna 202.

[0036] In FIG. 8 , tag A represents the time series change in the RSSI value of a tag inside the walk-through gate 91, and tag B represents the time series change in the RSSI value of a tag outside the walk-through gate 91. Also in FIG. 8 , t1 represents the timing when tag A approaches the entrance antenna 202, and t2 represents the timing when tag A approaches the exit antenna 202. That is, when an RFID tag passes through the walk-through gate 91, as shown by tag A in FIG. 8 , the time series change is maximized when the tag approaches the entrance and exit antennas 202. The determination unit 102 determines the reading accuracy of the commodity identification information based on whether the time series change in the RSSI value corresponds to the time series change when passing through a gate (walk-through gate 91) where a gate sensor 200 is installed at a predetermined position. Specifically, the determination unit 102 determines the reading accuracy based on whether the deviation from a graph showing the time series change in the RSSI value when correctly read is equal to or greater than a predetermined percentage.

[0037] [Second Embodiment] Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 9 is a block diagram showing an information processing device 110 according to the second embodiment. In the information processing system 11 according to this embodiment, the information processing device 110 is connected to a gate sensor 210 and an output device 310 via a network.

[0038] In the following, to the extent that the description of this embodiment is not unclear, the description of the same content as the above description will be omitted. As with the computer device shown in Figure 3, the functions of each component in each embodiment of the present disclosure can be realized not only by hardware but also by a computer device or software based on program control.

[0039] 9, the information processing device 110 includes an information acquisition unit 111, a determination unit 112, a storage status acquisition unit 113, a detection unit 114, and an output unit 115. The information acquisition unit 111, the determination unit 112, and the storage status acquisition unit 113 are similar to the corresponding configurations in the first embodiment, and therefore description thereof will be omitted.

[0040] The detection unit 114 is a means for detecting whether a customer is inside the gate. The detection unit 114 is configured, for example, to include a human presence sensor provided in each RFID reader 201 of the walk-through gate 91 in FIG. 2 . The human presence sensor may be an image sensor, an infrared sensor, or the like, and detects that a customer carrying an RFID-tagged product is passing near the antenna. The detection unit 114 detects that a customer is inside the gate from the time the customer is detected by the human presence sensor on the entrance side until the customer is detected by the human presence sensor on the exit side. In other words, even if a customer is detected by the human presence sensor on the entrance side, once the customer is detected by the human presence sensor on the exit side, the detection unit 114 detects that the customer has left the gate.

[0041] In addition to the functions of the output unit 104 in the first embodiment, the output unit 115 outputs guidance information for re-reading the commodity identification information based on whether or not the customer is inside the gate. That is, when the detection unit 114 detects that the customer is inside the gate, the output unit 115 outputs guidance information for having the commodity identification information read again by the gate sensor 210 inside the same gate. In this case, in order to improve the reading accuracy, guidance information may be output that asks the customer to shake the commodity storage means, bring the commodity storage means closer to the antenna 202 to have the information read again, change the orientation of the commodity storage means, or remove the commodity from the commodity storage means.

[0042] On the other hand, if the detection unit 114 does not detect that the customer is inside the gate, the output unit 115 outputs guidance information that guides the customer to another location to read the product identification information.

[0043] 10 is a flowchart showing an outline of the operation of the information processing device 110 in the second embodiment. Note that the processing according to this flowchart may be executed based on program control by the processor described above. The processing according to steps S201 to S204 in this flowchart is the same as the processing according to steps S101 to S104 in the flowchart in the first embodiment.

[0044] 10 , first, the information acquisition unit 111 acquires signal information from the RFID tag when the gate sensor 210 installed at the gate through which customers pass reads the commodity identification information stored in the RFID tag attached to the commodity (step S201). Next, the determination unit 112 determines the reading accuracy of the commodity identification information based on the signal information (step S202). Next, if the reading accuracy is determined to be low (S203; YES), the storage status acquisition unit 113 acquires the commodity storage status (step S204). On the other hand, if the reading accuracy is determined to be high (S203; NO), the storage status acquisition unit 113 ends the flow.

[0045] Next, if the product storage means is a shopping cart (S205; YES), the detection unit 114 detects whether the customer is inside the gate. If the customer is inside the gate (S206; YES), the output unit 115 outputs guidance information to have the product identification information read again by the gate sensor 210 inside the same gate (step S207). On the other hand, if the product storage means is not a shopping cart in S205 (S205; NO), or if the customer has left the gate in S206 (S206; NO), the output unit 115 outputs guidance information to guide the customer to another location to read the product identification information (step S208). This completes the information processing by the information processing device 110.

[0046] In the information processing device 110 of this embodiment, when a customer is inside a gate, the output unit 115 outputs guidance information to have the customer have the product scanned again by the gate sensor 210 inside the same gate. Furthermore, when the customer leaves the gate and the product identification information cannot be scanned again inside the gate, the output unit 115 outputs guidance information to guide the customer to another location to scan the product identification information. Therefore, appropriate guidance for scanning the product identification information again can be provided depending on the customer's location.
