[0016] Hereinafter, with reference to the drawings, embodiments of a payment processing device, a biometric information registration device, a payment processing method, and a non-transitory recording medium for recording a program according to the present disclosure will be described in detail. The disclosed technology is not limited to these embodiments.

[0017] First Embodiment (Payment Processing Device 100) 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 the configuration of a payment processing device 100 according to the first embodiment. The payment processing device 100 is a device through which a customer who has shopped at a store pays for purchased items, and is installed, for example, near an exit of the store. The store is, for example, a retail store that sells clothing, food, etc. In this embodiment, it is assumed that payment is performed by the payment processing device 100 using a medium that records registered biometric information, which is biometric authentication information registered to identify the customer, and payment information used by the customer to pay for purchased items. In this embodiment, the medium refers to a terminal such as a smartphone carried by the customer, an IC (integrated circuit) card such as a point card, paper, or the like. If the medium is paper, code information in which the registered biometric information and payment information are embedded is printed on the medium.

[0018] Referring to FIG. 1 , the payment processing device 100 includes a purchase information acquisition unit 101, a registration information acquisition unit 102, a verification information acquisition unit 103, a verification unit 104, and a payment unit 105. FIG. 2 is a diagram illustrating an example of a hardware configuration in which the payment 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. 2 , the payment 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 payment processing device 100 is connected to each component via a bus 510. Furthermore, the payment processing device 100 according to the first embodiment shown in FIG. 1 can also be configured using cloud computing or the like.

[0019] CPU 501 runs an operating system to control the entire payment processing device 100 according to the first embodiment of the present invention. CPU 501 also reads programs and data into memory from a recording medium 506 mounted in, for example, a drive device 507. CPU 501 also functions as purchase information acquisition unit 101, registration information acquisition unit 102, verification information acquisition unit 103, verification unit 104, and payment unit 105 according to the first embodiment, or as part of these, and executes processing or commands in the flowchart shown in FIG. 4, 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 Figure 1 is realized by the computer hardware shown in Figure 2. However, the means for realizing each unit of payment processing device 100 in Figure 1 is not limited to the configuration described above. Payment 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 separate devices connected by wire or wirelessly.

[0022] The purchase information acquisition unit 101 is a means for acquiring information about products purchased by a customer. In this embodiment, if the purchased products are previously equipped with RFID tags, the purchase information acquisition unit 101 acquires information about the purchased products read by an RFID reader. The RFID reader may be provided in the payment processing device 100, or may be provided in a product storage means such as a shopping basket or checkout cart used by the customer. Furthermore, if the customer scans the purchased products using a shopping application program, the purchase information acquisition unit 101 may acquire information about the purchased products scanned by the customer via the application program. The purchase information acquisition unit 101 outputs the acquired information about the purchased products to the payment unit 105.

[0023] The registration information acquisition unit 102 is a means for acquiring registered biometric information, which is biometric authentication information for identifying a customer, and payment information, which are recorded on a medium held by the customer. In this embodiment, the registered biometric information and payment information are stored in a contactless IC chip of the medium held by the customer, and the registration information acquisition unit 102 acquires the information recorded on the contactless IC chip using a contactless IC card reader. The registration information acquisition unit 102 outputs the acquired registered biometric information to the matching unit 104 and outputs the payment information to the payment unit 105.

[0024] The matching information acquisition unit 103 is a means for acquiring matching biometric information for verifying a customer at the time of payment. The matching information acquisition unit 103 acquires the same type of biometric authentication information as the registered biometric information. As the registered biometric information, any biometric authentication information that can identify a customer, such as facial authentication information, iris authentication information, fingerprint authentication information, or vein authentication information, is used. For example, if the registered biometric information is facial authentication information, the matching information acquisition unit 103 is configured with a camera and acquires data on the facial features of the customer at the time of payment. The matching information acquisition unit 103 outputs the acquired matching biometric information to the matching unit 104.

[0025] The matching unit 104 is a means for matching the registered biometric information with the matching biometric information. The matching unit 104 performs matching by comparing the feature data of the registered biometric information with the feature data of the matching biometric information using a known method. However, as long as it is possible to match the customer's biometric authentication information from both the registered biometric information and the matching biometric information, data other than feature data may be used for matching. The matching unit 104 outputs the matching result to the settlement unit 105.

[0026] If the registered biometric information matches the verified biometric information, the settlement unit 105 executes the settlement for the purchased goods using the customer's settlement information. After executing the settlement, the settlement unit 105 may send to the terminal carried by the customer a message notifying that the settlement has been completed or an electronic receipt including information on the purchased goods and the payment amount.

[0027] FIG. 3 is a diagram illustrating an example of a payment processing device 100. As shown in FIG. 3, the payment processing device 100 may be incorporated into a gate 20. The gate 20 includes a purchase information acquisition unit 101 including an RFID reader for reading RFID tags attached to each item purchased by a customer passing through the gate, a registration information acquisition unit 102 including a contactless IC card reader for reading registered biometric information and payment information recorded on a medium carried by the customer, and a verification information acquisition unit 103 including a camera for acquiring verification biometric information. Note that the verification unit 104 and the payment unit 105 may be provided in the gate 20 or in a server device (not shown).

[0028] In the example of payment processing device 100 in Figure 3, purchase information acquisition unit 101 is provided on the side wall of gate 20 (portions indicated by reference symbols 20A and 20B in the figure). Side walls 20A and 20B of gate 20 are wide enough to allow product storage means C and customers to pass through at the same time. Purchase information acquisition unit 101 communicates with the RFID tag attached to each purchased product and acquires product identification information stored in the recording area of ​​each RFID tag. Registration information acquisition unit 102, which consists of a contactless IC card reader, acquires registered biometric information and payment information from the contactless IC chip of a medium carried by the customer. Verification information acquisition unit 103, which consists of a camera, acquires the customer's verification biometric information.

[0029] In the example of payment processing device 100 in Figure 3, if the registered biometric information matches the verified biometric information and the authentication process is successful, the customer is permitted to pass through gate 20. For example, if the authentication process is successful, a door (not shown) on the entrance side of gate 20 is opened. Alternatively, a notification device (speaker, display, lamp, etc.) (not shown) may be provided at gate 20, and if the authentication process is successful, the notification device may be configured to audibly or visually notify the customer that they have been permitted to pass through.

[0030] The configuration of payment processing device 100 is not limited to the example in Fig. 3. Payment processing device 100 may be provided as a standalone device separate from gate 20. For example, acquisition of registration biometric information by registration information acquisition unit 102, acquisition of matching biometric information by matching information acquisition unit 103, and matching by matching unit 104 may be configured to include a BM1300-W22Q (face recognition + two-dimensional code compatible model) manufactured by NEC Platforms, Ltd.

[0031] 4 is a flowchart showing an outline of the operation of payment processing device 100 in the first embodiment. Note that the processing according to this flowchart may be executed based on program control by the processor described above.

[0032] First, the purchase information acquisition unit 101 acquires information about the products purchased by the customer (step S101). Next, the registration information acquisition unit 102 acquires registered biometric information, which is biometric authentication information for identifying the customer and payment information for the customer to pay for the purchased products, recorded on a medium carried by the customer (step S102). Next, the verification information acquisition unit 103 acquires verification biometric information for verifying the customer at the time of payment (step S103). Next, the verification unit 104 compares the registered biometric information with the verification biometric information (step S104). If the registered biometric information matches the verification biometric information (step S105; YES), the payment unit 105 executes payment processing for the purchased products using the customer's payment information (step S106) and notifies the customer that the payment processing is complete (step S107). On the other hand, if the registered biometric information does not match the verification biometric information (step S105; NO), the payment unit 105 notifies the customer that the verification biometric information does not match the registered biometric information (step S108). This completes the payment processing by payment processing device 100.

[0033] In the payment processing device 100 of this embodiment, the matching unit 104 matches registered biometric information, which is biometric authentication information for identifying the customer and is stored on a medium held by the customer, with matching biometric information for matching the customer at the time of payment. Furthermore, if the registered biometric information matches the matching biometric information, the payment unit 105 executes payment for the purchased item using the payment information recorded on the medium. This simplifies payment at the store without providing biometric authentication information, which is personal information, to third parties such as the store or a payment agent.

[0034] Second Embodiment Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. In the information processing system 11 of this embodiment, a biometric information registration device 110 and a payment processing device 210 are connected via a network.

[0035] 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 2, 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.

[0036] (Biometric Information Registration Device 110) The biometric information registration device 110 is a device that registers biometric authentication information of customers who visit a store to pay for purchased items, and is installed, for example, near the entrance of the store. Referring to Fig. 5, the biometric information registration device 110 includes a biometric information registration unit 111, a payment information acquisition unit 112, a generation unit 113, and an output unit 114.

[0037] The biometric information registration unit 111 is a means for registering biometric information, which is biometric authentication information for identifying a customer. The biometric information registration unit 111 has a function for registering biometric authentication information, and has a function for registering any biometric authentication information that can identify a customer, such as facial authentication information, iris authentication information, fingerprint authentication information, or vein authentication information. When registering facial authentication information, the biometric information registration unit 111 is configured with a camera and acquires data on the facial features of the customer.

[0038] The payment information acquisition unit 112 is a means for acquiring payment information for paying for purchased items. For example, the payment information acquisition unit 112 acquires payment information such as the customer's credit card information registered on a payment application program. A known method is used to acquire the payment information, and the payment information acquisition unit 112 acquires the payment information by, for example, reading a screen on the application program that displays the payment information as a two-dimensional code. Alternatively, the payment information acquisition unit 112 may read a screen on which a customer ID linked to the payment information is embedded in the two-dimensional code. In this case, the payment unit 215, described below, acquires the payment information linked to the customer ID from a server device in which customer information is stored.

[0039] The generation unit 113 is a means for generating code information in which registered biometric information and payment information are embedded. The code information is not particularly limited as long as it is information for identifying biometric authentication information and payment information, and includes numbers, symbols, and information obtained by converting these information into two-dimensional codes. In this embodiment, the generation unit 113 may generate code information that is valid for a predetermined period of time. The predetermined period may be, for example, a predetermined period of time, or a period in which a predetermined condition is met, such as while the customer is in the store. The generation unit 113 outputs the generated code information to the output unit 114.

[0040] The output unit 114 is a means for outputting the generated code information. The output unit 114 may print the code information on paper using a printer. Alternatively, the output unit 114 may write the code information in a recording area of ​​a medium held by the customer.

[0041] Fig. 6 is a diagram illustrating an example of a biometric information registration device 110. As shown in Fig. 6, the biometric information registration device 110 includes a biometric information registration unit 111 including a camera that registers registered biometric information, which is biometric authentication information for identifying a customer, a payment information acquisition unit 112 including a camera that reads a screen on which the customer's payment information is displayed as a two-dimensional code, a generation unit 113 that generates code information in which the registered biometric information and the payment information are embedded within the biometric information registration device 110, an output unit 114 including a printer, and an operation screen D. Note that the configuration of the biometric information registration device 110 is not limited to the example shown in Fig. 6.

[0042] (Payment processing device 210) Next, the payment processing device 210 will be described, focusing on the differences from the payment processing device 100 in the first embodiment. The payment processing device 210 includes a purchase information acquisition unit 211, a registration information acquisition unit 212, a matching information acquisition unit 213, a matching unit 214, and a settlement unit 215. The purchase information acquisition unit 211, the matching information acquisition unit 213, the matching unit 214, and the settlement unit 215 are the same as the corresponding components in the first embodiment.

[0043] In the first embodiment, the registration information acquisition unit 102 acquires registered biometric information and payment information recorded on a medium held by a customer. In contrast, the registration information acquisition unit 212 acquires registered biometric information and payment information embedded in code information. If the code information is printed on paper, the registration information acquisition unit 212 acquires the registered biometric information and payment information by, for example, reading the printed information with a camera. If the code information is recorded on an IC card held by the customer or on a contactless IC chip of a terminal, the registration information acquisition unit 212 acquires the registered biometric information and payment information using a contactless IC reader.

[0044] 7 is a flowchart showing an outline of the operation of the information processing system 11 in the second embodiment. Note that the processing according to this flowchart may be executed based on program control by the processor described above.

[0045] 7 is a flowchart showing the operation of the information processing system 11 according to the second embodiment. First, in the biometric information registration device 110, the biometric information registration unit 111 registers registered biometric information, which is biometric authentication information for identifying a customer (step S201). Next, the payment information acquisition unit 112 acquires payment information for the customer to pay for purchased items (step S202). Next, the generation unit 113 generates code information in which the registered biometric information and the payment information are embedded (step S203). Next, the output unit 114 outputs the code information (step S204).

[0046] In the payment processing device 210, the purchase information acquisition unit 211 first acquires information about the product purchased by the customer (step S205). Next, the registration information acquisition unit 212 acquires the registered biometric information and payment information embedded in the code information (step S206). Next, the verification information acquisition unit 213 acquires verification biometric information for verifying the customer at the time of payment (step S207). Next, the verification unit 214 verifies the registered biometric information with the verification biometric information (step S208). If the registered biometric information matches the verification biometric information (step S209; YES), the payment unit 215 executes payment for the purchased product using the customer's payment information (step S210) and notifies the customer that the payment process is complete (step S211). Next, on the other hand, if the registered biometric information does not match the verification biometric information (step S209; NO), the payment unit 215 notifies the customer that the verification biometric information does not match the registered biometric information (step S212). This completes the processing of the information processing system 11.

[0047] In this embodiment, the output unit 114 of the biometric information registration device 110 outputs code information in which registered biometric information and payment information are embedded. In this case, even if a user does not possess a medium on which personal information such as biometric authentication information is recorded, the user can make a payment without providing the personal information to a third party.

[0048] [Variation of Second Embodiment] Fig. 8 is a block diagram showing the configuration of an information processing system 12 according to a variation of the second embodiment. Referring to Fig. 8, a biometric information registration device 120 includes a biometric information registration unit 121, a payment information acquisition unit 122, a generation unit 123, an output unit 124, and an erasure unit 125.

[0049] In a variation of the second embodiment, the output unit 124 writes code information into the product storage means used by the customer. Specifically, the product storage means is equipped with an RFID tag, and the output unit 124 writes the code information into the RFID tag using an RFID writer. Furthermore, the erasing unit 125 erases the code information written in the product storage means upon detecting that the customer has finished shopping. For example, the erasing unit 125 detects that the customer has finished shopping when the product storage means moves to a collection location. Alternatively, the erasing unit 125 may detect that the customer has finished shopping when the product storage means passes through a gate. The erasing unit 125 detects that the customer has finished shopping by using a sensor provided at the collection location or the gate to detect radio waves or infrared rays emitted from a beacon or the like installed in the product storage means.

[0050] In the modified example of the second embodiment, the configurations other than the output unit 124 and the erasure unit 125 are the same as the corresponding configurations in the second embodiment.

[0051] In this embodiment, the output unit 124 writes the code information into the product storage means used by the customer. In this case, the product storage means used by the customer when shopping is used to record personal information such as biometric authentication information, thereby improving convenience for the customer.
