[0014] In the present invention, a "purchase-restricted product" refers to, for example, a product that can only be purchased by persons with a specific attribute. The specific attribute is not particularly limited and may include, for example, age, gender, occupation, etc. Specific examples of purchase-restricted products include age-restricted products such as alcohol and tobacco, medicines or medical devices that can only be purchased by medical professionals, and prescription drugs. The purchase-restricted product may be, for example, a product whose purchase or sale is restricted by law or regulation, or a product that is subject to self-regulation by an industry association or the like. The prescription drug is, for example, a pharmaceutical product that is supplied for use by a physician or dentist, or for use according to a prescription or instruction from such a physician or dentist. In the present invention, the prescription or instruction may be a prescription or instruction issued through a face-to-face consultation or an online consultation.

[0015] Next, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments. In the following drawings, the same parts are denoted by the same reference numerals. Furthermore, the descriptions of the embodiments can be mutually incorporated unless otherwise specified, and the configurations of the embodiments can be combined unless otherwise specified.

[0016] [Embodiment 1] The purchase eligibility determination device of this embodiment will be described with reference to FIG. 1. FIG. 1 is a block diagram showing an example of the configuration of a purchase eligibility determination device 10 of this embodiment. As shown in FIG. 1, the purchase eligibility determination device 10 (hereinafter also referred to as "the device 10") includes an authentication standard information acquisition unit 11, an identification information acquisition unit 12, an authentication unit 13, and a purchase eligibility determination unit 14. Although not shown, the device 10 may also include, for example, a memory unit. Although not shown, the purchase eligibility determination device 10 may be connectable to an external database via a communication network. Furthermore, although not shown, the purchase eligibility determination device 10 may also be connectable to an external terminal of a system administrator via a communication network, for example, and the system administrator may manage the purchase eligibility determination device 10 from the external terminal. Preferably, the purchase eligibility determination device 10 is, for example, a device incorporated into a payment device described later in embodiment 2 or a device capable of communicating with the payment device.

[0017] The device 10 may be, for example, a single device including the above-described units, or a device in which the units can be connected via a communication network. The device 10 can also be connected to an external device (described later) via the communication network. The communication network is not particularly limited, and any known network can be used, for example, wired or wireless. Examples of communication networks include the Internet, the World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area Network (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, and LPWA. Examples of wireless communication include direct communication between devices (Ad Hoc communication), infrastructure communication, and indirect communication via an access point. The device 10 may be incorporated into a server as a system. The device 10 may be, for example, a personal computer (PC, for example, a desktop or notebook type) on which the program of the present invention is installed, a smartphone, a tablet terminal, etc. Furthermore, the device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the units is located on a server and the other units are located on a terminal.

[0018] 2 shows a block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a CPU 101, a memory 102, a bus 103, a storage device 104, an input device 106, an output device 107, and a communication device 108. The components of the device 10 are connected to each other via the bus 103 and their respective interfaces (I / F).

[0019] The CPU 101 cooperates with other components, for example, via a controller (such as a system controller or an I / O controller), and is responsible for overall control of the device 10. In the device 10, the CPU 101 executes, for example, the program 105 of the present invention and other programs, and also reads and writes various types of information. Specifically, for example, the CPU 101 functions as an authentication standard information acquisition unit 11, an identification information acquisition unit 12, an authentication unit 13, and a purchase eligibility determination unit 14. The device 10 includes a CPU as a computing device, but may also include other computing devices such as a GPU (Graphics Processing Unit) or an APU (Accelerated Processing Unit), or may include a combination of the CPU and these.

[0020] The bus 103 can also be connected to, for example, external devices. Examples of the external devices include a payment device, a product storage device, an external storage device (such as an external database), a printer, an external input device, an external display device, and an external imaging device. The device 10 can be connected to an external network (the communication line network) by, for example, a communication device 108 connected to the bus 103, and can also be connected to other devices via the external network.

[0021] The memory 102 may be, for example, a main memory (primary storage device). When the CPU 101 performs processing, the memory 102 reads various operation programs 105, such as the program of the present invention, stored in a storage device 104 (described later), and the CPU 101 receives data from the memory 102 and executes the program. The main memory may be, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0022] The storage device 104 is also referred to as an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program 105 including the program of the present invention. The storage device 104 may be, for example, a combination of a recording medium and a drive for reading and writing data from and to the recording medium. The recording medium is not particularly limited and may be, for example, an internal or external type, such as a hard disk (HDD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) or a solid-state drive (SSD) in which the recording medium and drive are integrated. When the device 10 includes, for example, the storage unit, the storage device 104 functions as the storage unit. When the device 10 includes the storage unit, for example, the storage unit may store information acquired or generated by the device.

[0023] In the present device 10, the memory 102 and the storage device 104 can also store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by the present device 10, and information used when the present device 10 executes processing. Note that at least a portion of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0024] The device 10 further includes, for example, an input device 106 and an output device 107. Examples of the input device 106 include a pointing device such as a touch panel, track pad, or mouse; a keyboard; an imaging device such as a camera or scanner; a card reader such as an IC card reader or a magnetic card reader; and an audio input device such as a microphone. Examples of the output device 107 include a display device such as an LED display or a liquid crystal display; an audio output device such as a speaker; a printer; etc. In the first embodiment, the input device 106 and the output device 107 are configured separately, but the input device 106 and the output device 107 may also be configured as an integrated device, such as a touch panel display.

[0025] Next, an example of the purchase eligibility determination method of this embodiment will be described with reference to the flowchart of Fig. 3. The purchase eligibility determination method of this embodiment is implemented as follows, for example, using the purchase eligibility determination device 10 shown in Fig. 1 or 2. Note that the purchase eligibility determination method of this embodiment is not limited to use with the purchase eligibility determination device 10 shown in Fig. 1 or 2.

[0026] First, prior to processing by the device 10, for example, the user's personal identification information and attribute information regarding whether or not a purchase-restricted product can be purchased are linked in advance as authentication reference information. The personal identification information is information that can uniquely identify an individual user, and may be, for example, biometric information or non-biometric information. The biometric information is not particularly limited, and various types of information used in known biometric authentication can be used. Specific examples include facial information such as facial features; iris information; ocular vascular information; audio information such as voiceprints; fingerprint information; palm print information; vein information such as finger veins; ear acoustic information; auricle information; genetic information; and behavioral biometric information such as handwriting, keyboard keystrokes, blinking, and gait. The non-biometric information is not particularly limited, and examples include identification numbers such as email addresses, telephone numbers, My Numbers, IDs, passwords, and device-specific information of the user's device (device serial numbers, device identification numbers such as International Mobile Equipment Identifiers). The attribute information regarding whether or not the purchase-restricted product can be purchased can be set appropriately depending on the type of the purchase-restricted product, and may include, for example, the user's age, sex, occupation, disease status, prescription information from a doctor or dentist (for example, electronically entered information on a paper prescription, or electronic prescription information), etc. The authentication standard information may be stored, for example, in the storage device 104 of the device 10, in a database or server outside the device, or recorded on an authentication medium described below, but is preferably recorded on an authentication medium from the viewpoint of privacy protection.

[0027] Examples of the authentication medium include a card or terminal on which an identification symbol such as a one-dimensional code or a two-dimensional code is displayed; and an information recording medium (e.g., an NFC tag, a FeliCa (registered trademark) tag, etc.) that uses a non-contact communication technology such as NFC (Near Field Communication). The two-dimensional code is not particularly limited and may be, for example, a stack type or a matrix type. Specific examples of the identification symbol include one-dimensional codes such as a barcode; and two-dimensional codes such as QR Code (registered trademark), CP Code, Data Matrix, MaxiCode, VeriCode, Semacode, AztecCode, PDF417 (registered trademark), UCC / EAN Composite, and Chameleon Code (registered trademark), with QR Code (registered trademark) being preferred. When the authentication standard information is recorded on the authentication medium, for example, an authentication medium containing the authentication standard information can be created by generating an authentication medium (e.g., a card or NFC tag on which a QR Code (registered trademark) is printed) on which the personal identification information and attribute information regarding whether or not a purchase-restricted product can be purchased are recorded.

[0028] The authentication standard information may be linked to other information, such as a user ID, address, name, and date of birth.

[0029] The authentication reference information acquisition unit 11 of the device 10 acquires the authentication reference information (S1, authentication reference information acquisition step). The authentication reference information acquisition unit 11 may acquire the authentication reference information from a database or server that stores the authentication reference information, for example, via a communication network. Alternatively, the authentication reference information acquisition unit 11 may acquire the authentication reference information by acquiring read information obtained by reading an authentication medium containing the authentication reference information and extracting the authentication reference information from the read information. In the latter case, the read information may be acquired by reading the authentication medium using an authentication medium reader connected to the bus 103 of the device 10. The reader is not particularly limited, and a reader appropriate for the type of authentication medium may be used. Specific examples of the reader include a QR Code (registered trademark) reader and an NFC reader. The authentication reference information acquisition unit 11 may acquire the authentication reference information by, for example, acquiring read information obtained by reading the authentication medium using the reader and extracting the authentication reference information from the read information.

[0030] Next, the identification information acquisition unit 12 acquires the identification information of the person to be authenticated (S2, identification information acquisition step). The identification information is, for example, information that can uniquely identify an individual, and any information corresponding to the personal identification information can be acquired. The identification information acquisition unit 12 acquires the identification information of the person to be authenticated, for example, by acquiring various information using an appropriate input means depending on the type of the identification information. As a specific example, if the identification information is facial information, it can be acquired using an imaging means such as a camera. If the identification information is audio information, it can be acquired using an audio input means such as a microphone. If the identification information is the phone number of the terminal of the person to be authenticated, it can be acquired, for example, by having the terminal of the person to be authenticated make a call to an authentication phone number specified by the device 10. The identification information acquisition unit 12 may acquire information, for example, from the various input means, or may acquire information from a storage device in which information acquired by the various input means is recorded. The identification information may be acquired, for example, directly or indirectly. An example of the direct acquisition is when the purchase eligibility determination device 10 directly acquires the identification information of the person to be authenticated using an input device 106 (e.g., an imaging device such as a camera, or an audio input device such as a microphone) connected to the bus 103. An example of the indirect acquisition is when the identification information of the person to be authenticated is indirectly acquired via an agent of the person to be authenticated.

[0031] The authentication unit 13 authenticates the person to be authenticated by comparing the identification information of the person to be authenticated with the personal identification information included in the authentication reference information (S3, authentication step). The authentication unit 13 can authenticate the person to be authenticated, for example, using an appropriate authentication method depending on the personal identification information and the identification information of the person to be authenticated. The authentication method may be, for example, biometric authentication or non-biometric authentication. Examples of biometric authentication include face authentication, iris authentication, eyeball blood vessel authentication, voice authentication, fingerprint authentication, palm print authentication, vein authentication, ear acoustic authentication, ear authentication, genetic authentication, and behavioral biometric authentication. Examples of non-biometric authentication include incoming call authentication using a telephone number. The authentication unit 13, for example, performs a one-to-one comparison between the identification information of the person to be authenticated and the personal identification information included in the authentication reference information to determine whether the person to be authenticated and the person identified by the personal identification information in the authentication reference information are the same person. If the identification information of the person to be authenticated matches the personal identification information (S3, Yes), the authentication unit 13 certifies that the person to be authenticated and the person identified by the personal identification information in the authentication reference information are the same person, i.e., that the person to be authenticated is the person identified by the personal identification information included in the authentication reference information. For example, if the device 10 authenticates that the person to be authenticated is the person identified by the personal identification information included in the authentication reference information, it proceeds to step S4. On the other hand, if the identification information of the person to be authenticated does not match the personal identification information (S3, No), the authentication unit 13 determines that the person to be authenticated and the person identified by the personal identification information in the authentication reference information are not the same person, i.e., does not authenticate the person to be authenticated. Information on the authentication result by the authentication unit 13 is also referred to as, for example, an authentication log.

[0032] The authentication unit 13 may further perform, for example, biometric determination. The biometric determination is, for example, a step of determining whether the identification information of the person to be authenticated acquired in S2 is information based on a living body, and a known biometric determination method may be used as appropriate depending on the type of acquired identification information. Specific examples include, when the identification information is facial information, methods such as blink detection, tilting the face in a specified order, or changing facial expressions.

[0033] If the authentication is successful (S3, YES), the purchase eligibility determination unit 14 determines that the person to be authenticated is allowed to purchase the purchase-restricted product (S4, purchase eligibility determination step), and ends the process (END). For example, if the authentication fails (S3, No), the purchase eligibility determination unit 14 ends the process (END). Note that the present invention is not limited to this, and for example, if the authentication fails (S3, No), the process may return to any of steps S1 to S3 and repeat the process.

[0034] In the present embodiment, the purchase eligibility determination method has been described using an example in which steps S1 to S4 are executed sequentially, but the present invention is not limited to this. Specifically, in the present invention, steps S1 and S2 may be executed upstream of step S3, and steps S1 and S2 may be executed simultaneously or separately. In the latter case, the order of execution is not particularly limited and is arbitrary.

[0035] According to the purchase eligibility determination device of this embodiment, it is possible to easily determine whether the person to be authenticated can purchase a purchase-restricted product, i.e., whether the person to be authenticated is eligible to purchase a purchase-restricted product. Furthermore, the purchase eligibility determination device of this embodiment authenticates the person to be authenticated by using an authentication unit to compare the identification information of the person to be authenticated with the personal identification information included in the authentication standard information, thereby preventing, for example, impersonation purchases by persons who are not eligible to purchase purchase-restricted products (for example, minors in the sale of alcoholic beverages, non-medical professionals in the sale of controlled medical devices, persons without prescriptions in the prescription and sale of medical drugs, etc.).

[0036] [Embodiment 2] The second embodiment is an example of the payment device of the present invention.

[0037] The payment device of this embodiment will be described with reference to FIG. 4. FIG. 4 is a block diagram showing an example of the configuration of the payment device of this embodiment. As shown in FIG. 4(A), the payment device 20 of this embodiment includes, for example, a purchase eligibility determination unit 10, a purchase candidate product information acquisition unit 21, a purchase-restricted product detection unit 22, and a payment unit 23. The purchase eligibility determination unit 10 is similar to, for example, the purchase eligibility determination device 10 of embodiment 1, and the description therefor can be used. In the following description, the term "purchase eligibility determination unit" can be read as, for example, "purchase eligibility determination device." Furthermore, although not shown, the payment device 20 may include, for example, a memory unit.

[0038] The payment device 20 may be, for example, a single device including the above-mentioned units, or a device in which the above-mentioned units can be connected via a communication network. Furthermore, the payment device 20 can be connected to an external device (described later) via the communication network. The communication network is, for example, as described above. The payment device 20 may be incorporated into a server as a system. Furthermore, the payment device 20 is preferably, for example, a so-called POS (Point of Sale) device, particularly a POS device at an unmanned sales outlet. The payment device 20 may be, for example, a personal computer (PC, e.g., desktop or laptop) on which the program of the present invention is installed, a smartphone, a tablet terminal, or the like. Furthermore, the payment device 20 may be, for example, a form of cloud computing or edge computing in which at least one of the above-mentioned units is located on a server and the other units are located on a terminal. As a specific example, as shown in Figure 4(B), there is a form of payment system 100 in which a POS device 20 including a purchase restricted product detection unit 21, a purchase restricted product detection unit 22, and a payment unit 23 is connected to the purchase eligibility determination unit 10 of the above-mentioned embodiment 1 via a communication network 30.

[0039] In the payment device of embodiment 2, for example, the purchase target product information acquisition unit 21 acquires purchase target product information, the purchase restriction product detection unit 22 detects whether the purchase target product information includes a purchase restriction product, and the purchase eligibility determination unit 10 determines whether the purchase restriction product can be purchased if the purchase target product information includes a purchase restriction product.

[0040] FIG. 5 illustrates a block diagram of the hardware configuration of the payment device 20. As shown in FIG. 5, the payment device 20 includes, for example, a CPU 201, a memory 202, a bus 203, a storage device 204, an input device 206, an output device 207, and a communication device 208. The description of each component of the payment device 20 can be used to refer to the description of each component of the purchase eligibility determination device 10. The components of the payment device 20 are connected via the bus 203 and their respective interfaces (I / F). In the payment device 20, the CPU 201 functions as a purchase candidate product information acquisition unit 21, a purchase-restricted product detection unit 22, and a payment unit 23. In the payment device 20 illustrated in FIG. 5, the purchase eligibility determination unit 10 (purchase eligibility determination device 10) is connected to the bus 203, for example, but the present invention is not limited thereto. In the payment device 20, for example, the purchase eligibility determination unit 10 may be connected via the communication network 30 by, for example, the communication device 208, or a program for executing each process of the purchase eligibility determination method of the first embodiment may be stored in the storage device 204 or memory 202, and the CPU 201 may read and execute the program, thereby functioning as the purchase eligibility determination unit 10.

[0041] Next, an example of the payment method of this embodiment will be described with reference to the flowchart of Fig. 6. The purchase possibility determination method of this embodiment is implemented as follows, for example, using the payment device 20 of Figs. 4 and 5. Note that the payment method of this embodiment is not limited to use of the payment device 20 of Figs. 4 and 5.

[0042] First, the intended purchase product information acquisition unit 21 of the payment device 20 acquires intended purchase product information (S21, intended purchase product information acquisition step). Specifically, for example, the intended purchase product information acquisition unit 21 can read the intended purchase product identification information using a reader connected to the payment device 20 and acquire the intended purchase product information based on the intended purchase product identification information. The intended purchase product identification information may be, for example, a product identification code such as a JAN code, an EAN code, a UPC code, an ITF (Interleaved Two of Five), CODE39, Code128, or NW-7; image information on the product package; or the like. The intended purchase product information acquisition unit 21 can be appropriately selected depending on the intended purchase product identification information. In the payment device 20, the intended purchase product information acquisition unit 21 may read the intended purchase product information using the reader, for example, by the user or by an administrator (e.g., a store clerk) of the payment device 20. However, a self-checkout system in which the user can perform the reading operation is preferable. Note that the intended purchase product information acquisition unit 21 may acquire the intended purchase product information without any particular limitations, and various methods used in known payment devices may be used.

[0043] Next, the purchase-restricted product detection unit 22 of the payment device 20 detects whether the intended purchase information includes a purchase-restricted product (S22, purchase-restricted product detection step). Specifically, the purchase-restricted product detection unit 22 identifies each product included in the intended purchase information based on, for example, product identification information attached to each product included in the intended purchase information, and determines whether the identified product is linked to purchase restriction information as product attribute information. The purchase-restricted product detection unit 22 then extracts products whose attribute information is linked to purchase restriction information, thereby detecting whether a purchase-restricted product is included. The product attribute information includes, for example, product name, price, purchase restriction information, etc. The link between the product identification information and the product attribute information may be stored, for example, as a product master file in the storage device 204 or memory 202 of the payment device 20, or may be stored in a database external to the device.

[0044] If the purchase-restricted product is not included in the purchase-intent product information (S22, No), the settlement unit 23 performs payment for the purchase-intent products (S23). Specifically, the settlement unit 23 may perform payment by, for example, acquiring price information for the purchase-intent products based on product attribute information for the purchase-intent products identified based on the product identification information, and settling the price for each product. The present invention is not limited to this example. For example, the settlement unit 23 may acquire price information for the purchase-intent products based on the product attribute information for the purchase-intent products identified based on the product identification information, transmit the price information for the purchase-intent products to a settlement server external to the device via the communication network 30, and obtain a settlement result from the settlement server, thereby performing payment for the purchase-intent products. The payment process is not particularly limited, and various methods used in well-known settlement devices may be used, for example.

[0045] If the purchase-restricted product is included in the purchase-intent product information (S22, Yes), the purchase permission determination unit 10 executes steps S1 to S4 in the same manner as steps S1 to S4 in the first embodiment. At this time, the payment device 20 may also output guidance information. The guidance information may be, for example, information for prompting the authentication target person to perform authentication, and specifically, information for informing the authentication target person of the location of a reading device for the authentication reference information. The guidance information may be output, for example, to the output device 207 of the payment device 20, or may be output from a reading device such as a QR Code (registered trademark) reader connected to the payment device 20. The output of the guidance information is not particularly limited, and may be, for example, audio output, information display, or a combination of both. Specifically, when the guidance information is displayed on the output device 207, text information such as "Age verification is required. Please hold your card over the QR code reader for face authentication" may be output as the guidance information to the output device 207 of the payment device 20. At this time, for example, audio information may also be output from the output device 207. The audio information is not particularly limited and may be, for example, information in which the text information is read aloud, or a notification sound informing that the guidance information has been output. Specific examples of outputting the guidance information from the reading device include illuminating a light-emitting unit provided in the reading device or generating a sound from a speaker. The output of the guidance information may be, for example, a combination of multiple methods. Then, if it is determined in S4 that the person to be authenticated is able to purchase the restricted purchase item, the payment unit 23 makes payment for the intended purchase item (S23). Furthermore, as shown in FIG. 6, in this embodiment, if the person to be authenticated cannot be authenticated in S3 (S3, No), for example, the process may return to S21 and repeat the process from S21.

[0046] Furthermore, if the purchase-restricted product is included in the intended purchase product information (S22, Yes), the payment device 20 may wait for a predetermined time after S22 to input information. In this case, for example, if at least one of the authentication standard information and the identification information of the person to be authenticated cannot be acquired even after the predetermined time has elapsed (i.e., if a timeout occurs), the payment device 20 may return to step S21 and repeat the process from S21. The predetermined time may be set arbitrarily without any particular limitations, and specific examples include 10 seconds, 30 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes, and 5 minutes. Furthermore, when returning to step S21, the output device 207 of the payment device 20 may output information such as "Age verification failed. Please start over from the beginning."

[0047] In the settlement method of this embodiment, an example has been described in which S21, S22, S1 to S4, and S23 are executed in sequence, but the present invention is not limited to this. Specifically, in the present invention, S1 and S2 may be executed in a process upstream of S3, and S1 and S2 may be executed simultaneously with S21 and S22, for example, or may be executed separately. In the latter case, the order of execution is not particularly limited and is arbitrary.

[0048] Furthermore, in the payment method of this embodiment, the identification information of the person to be authenticated is acquired after the user has scanned the product into payment device 20, but the present invention is not limited to this. For example, if an imaging device such as a camera is installed at the entrance of a sales outlet (store) where the payment device of the present invention is installed, a facial image of the person to be authenticated may be captured when the person to be authenticated enters the store, and the facial image may be used as the identification information of the person to be authenticated.

[0049] According to the payment device of this embodiment, when a purchase-restricted item is included in the items to be purchased, it is possible to easily determine whether the person to be authenticated is eligible to purchase the purchase-restricted item. Furthermore, the payment device of this embodiment authenticates the person to be authenticated by using an authentication unit to compare the identification information of the person to be authenticated with the personal identification information included in the authentication standard information. This makes it possible to prevent, for example, impersonation purchases by persons who are not eligible to purchase the purchase-restricted item (e.g., minors in the case of alcoholic beverages). Therefore, the payment device of this embodiment can be suitably used, for example, when selling purchase-restricted items such as alcoholic beverages at unmanned vending machines. [Embodiment 3] The third embodiment is an example of use of the settlement device 20 of the second embodiment.

[0050] In this embodiment, for example, a case will be described in which a user (store patron) at an unmanned vending machine where the payment device 20 of the present invention is installed possesses a card (hereinafter also referred to as a "license") on which a QR code (registered trademark) recording the authentication standard information is printed as the authentication medium, and purchases alcoholic beverages, which are age-restricted products, as the purchase-restricted product. As described above, in the payment method of the present invention, the authentication medium is not limited to a printed matter on which a QR code (registered trademark) is printed, and the purchase-restricted product is not limited to alcoholic beverages. Furthermore, in the following examples, the payment device 20 of the present invention is a POS terminal connected to a barcode reader, and the purchase eligibility determination unit 10 is a tablet terminal equipped with a camera connected to a QR code (registered trademark), but the present invention is not limited to the following examples.

[0051] First, before visiting the unmanned vending machine, the user goes to a license issuing venue operated by the management organization of the unmanned vending machine and presents identification such as a driver's license to the management organization to prove that the user is 20 years of age or older, i.e., is eligible to purchase alcoholic beverages. The management organization confirms the user's identity by checking the user's face and the photo on the driver's license, and verifies that the user is 20 years of age or older. Once the user's identity and age have been confirmed, the management organization captures a facial image of the user, analyzes the facial image to acquire the user's facial features (identification information), generates a QR code (registered trademark) recording the facial features and the user's age, and issues a card (license) on which the QR code (registered trademark) is printed. Note that a QR code (registered trademark) recording user identification information (e.g., a user ID) linked to the user's age information or date of birth information may be generated instead of the user's age.

[0052] Next, at an unmanned vending machine equipped with the payment device 20 of the present invention, the user scans the barcode of a product containing alcoholic beverages using a barcode reader connected to the payment device 20. The payment device 20 acquires the user's intended purchase product information based on the barcode scanned by the user using the intended purchase product information acquisition unit 21, and detects alcoholic beverages from the intended purchase product information using the purchase restriction product detection unit 22. The payment device 20 then displays a message on its output device 207 as the guidance information, urging the user to perform authentication, and causes the light-emitting unit of the QR Code (registered trademark) reader connected to the payment device 20 to emit light. An example of the message is, "There are products that require age verification. Please hold your permit over the QR code reader for face authentication."

[0053] The user who is prompted to be authenticated scans the QR code (registered trademark) on the permit with the QR code (registered trademark) reader, and takes a picture of his or her face with the camera of the tablet terminal (purchase permission determination unit 10).

[0054] The QR code (registered trademark) reader generates read information by reading the QR code (registered trademark) on the permit and transmits the read information to the payment device 20. Then, the purchase eligibility determination unit 10 authenticates the user by comparing the authentication standard information extracted from the read information with the facial image and determines whether the user is eligible to purchase the purchase-restricted product. If the user is authenticated, the payment device 20 determines that the user is eligible to purchase the purchase-restricted product and performs payment processing. In this way, the payment device 20 of the present invention can determine whether the user is eligible to purchase the purchase-restricted product, i.e., whether the user is eligible to purchase the purchase-restricted product.

[0055] [Variation 1] In the present embodiment, a case has been described in which a user (a store patron) possesses a card (hereinafter also referred to as a "license") on which a QR code (registered trademark) recording the authentication reference information is printed as the authentication medium at an unmanned vending machine where the payment device 20 of the present invention is installed, and purchases an age-restricted alcoholic beverage as the purchase-restricted product. However, the present invention is not limited to this. For example, the present invention may also be configured such that an agent of the user possesses the license instead of the user himself / herself, whose identification information is recorded on the license, and the agent purchases the purchase-restricted product on behalf of the user. As a modified example, a specific example will be described below in which an agent possessing a card (license) on which a QR code (registered trademark) recording the user's identification number (telephone number) linked to the user's age, instead of the facial features, is printed, and purchases a purchase-restricted product on behalf of the user.

[0056] First, at the permit issuing venue, the user is issued a card (permit) on which a QR code (registered trademark) is printed, in which the user's identification number (telephone number) is linked to the user's age, instead of the facial features, as the user's identification information. The user then lends the permit to the user's proxy. The proxy scans barcodes of products, including alcoholic beverages, at an unmanned vending machine where the payment device 20 of the present invention is installed, using a barcode reader connected to the payment device 20. The payment device 20 acquires the proxy's intended purchase product information based on the barcode scanned by the proxy using the intended purchase product information acquisition unit 21, detects alcoholic beverages from the intended purchase product information using the purchase restriction product detection unit 22, and outputs the guidance information in the same manner as described above to prompt the proxy to authenticate.

[0057] The agent, who is prompted to be authenticated, scans the QR code (registered trademark) on the permit with the QR code (registered trademark) reader. The QR code (registered trademark) reader generates read information by reading the QR code (registered trademark) on the permit, and transmits the read information to the payment device 20.

[0058] The authentication standard information acquisition unit 11 of the purchase eligibility determination unit (purchase eligibility determination device) 10 of the payment device 20 extracts the identification number (telephone number) information from the read information as the authentication standard information. When the identification number (telephone number) is extracted, the identification information acquisition unit 12 of the purchase eligibility determination device 10 outputs identification information acquisition information to, for example, its output device 107. The identification information acquisition information is, for example, telephone number information to be used for incoming call authentication. At this time, the payment device 20 may also display, for example, information such as "Age verification is required. Please call the telephone number displayed on the tablet terminal to perform incoming call authentication" on the output device 207 as the guidance information.

[0059] The agent, for example, notifies the user who is the subject of authentication of the telephone number in the identification information acquisition information, and the user who is the subject of authentication calls the telephone number specified in the identification information acquisition information from a terminal having the telephone number recorded on the permit. Then, the identification information acquisition unit 12 acquires, for example, the telephone number received at the telephone number specified in the identification information acquisition information as the identification information of the person to be authenticated. Then, the authentication unit 13 authenticates the user by comparing the authentication standard information (telephone number) extracted from the read information with the telephone number and determines whether the user can purchase the purchase-restricted product. If the user is authenticated, the payment device 20 performs payment processing, assuming that the agent is an agent of a user who is eligible to purchase the purchase-restricted product.

[0060] In this way, the payment device 20 of the present invention can easily determine whether the person to be authenticated is allowed to purchase a purchase-restricted product, even if the purchase is made by a proxy. Therefore, even if the person to be authenticated does not visit the store in person, the payment device 20 of the present invention authenticates the person to be authenticated by comparing the identification information of the person to be authenticated with the personal identification information included in the authentication standard information, thereby preventing, for example, impersonation purchases by persons who are not eligible to purchase purchase-restricted products (for example, minors in the sale of alcoholic beverages, non-medical professionals in the sale of controlled medical devices, persons without prescriptions in the prescription and sale of medical drugs, etc.).

[0061] [Embodiment 4] The fourth embodiment is an example of a product storage device of the present invention.

[0062] The product storage device of this embodiment will be described with reference to FIG. 7. FIG. 7 is a block diagram showing an example of the configuration of the product storage device of this embodiment. As shown in FIG. 7, the product storage device 40 of this embodiment includes, for example, a purchase eligibility determination unit 10 and an unlocking control unit 41. The purchase eligibility determination unit 10 is similar to, for example, the purchase eligibility determination device 10 of embodiment 1, and the description thereof can be used. Therefore, in the following description, the term "purchase eligibility determination unit" can be read as, for example, a "purchase eligibility determination device." Furthermore, although not shown, the product storage device 40 may include, for example, a memory unit.

[0063] The product storage device 40 may be, for example, a single device including each of the above-mentioned units, or a device in which each of the above-mentioned units can be connected via a communication network. Furthermore, the product storage device 40 may be connectable to an external device, for example, via the communication network 30. An example of the external device is a product storage cabinet 42. The unlocking control unit 41 of the product storage device 40 may, for example, control the locking state of the product storage cabinet 42. The product storage device 40 may be incorporated into a server as a system. For example, the product storage device 40 may be connected to a bus of a control device of the product storage cabinet 42 and configured as a control device for the product storage cabinet 42. Furthermore, the product storage device 40 may be, for example, a personal computer (PC, for example, a desktop or laptop) on which the program of the present invention is installed, a smartphone, a tablet terminal, or the like. Furthermore, the product storage device 40 may be, for example, a cloud computing or edge computing system in which at least one of the above-mentioned units is located on a server and the other units are located on a terminal.

[0064] Product storage cabinet 42 is, for example, a storage cabinet for storing purchase-restricted products, and other configurations are not particularly limited as long as it is a product storage cabinet whose locking state can be controlled. As a specific example, product storage cabinet 42 includes, for example, an exterior unit, a lockable door unit, a product display unit, a temperature adjustment unit, a humidity adjustment unit, a control unit capable of controlling each of these units, etc.

[0065] FIG. 8 illustrates a block diagram of the hardware configuration of the product storage device 40. As shown in FIG. 8, the product storage device 40 includes, for example, a CPU 401, a memory 402, a bus 403, a storage device 404, an input device 406, an output device 407, and a communication device 408. The explanation of each component of the product storage device 40 can be cited from the explanation of each component of the purchase eligibility determination device 10. The components of the product storage device 40 are connected via the bus 403 through their respective interfaces (I / F). In the product storage device 40, the CPU 401 functions as the unlock control unit 41. In the product storage device 40 illustrated in FIG. 8, the purchase eligibility determination unit 10 (purchase eligibility determination device 10) is connected to, for example, the bus 403, but the present invention is not limited to this. In the product storage device 40, for example, the purchase eligibility determination unit 10 may be connected via the communication network 30 by, for example, a communication device 408, or a program for executing each process of the purchase eligibility determination method of embodiment 1 may be stored in the storage device 404 or memory 402, and the CPU 401 may function as the purchase eligibility determination unit 10 by reading and executing the program.

[0066] Next, an example of the product storage method of this embodiment will be described based on the flowchart in Fig. 9. The product storage method of this embodiment is implemented as follows, for example, using the product storage device 40 of Figs. 7 and 8. Note that the product storage method of this embodiment is not limited to use of the product storage device 40 of Figs. 7 and 8. In the following explanation, an example will be given in which alcohol, an age-restricted product, is stored in a product storage cabinet 42 incorporating the product storage device 40, and a user whose age has been authenticated by the product storage device 40 removes the alcohol, but the present invention is in no way limited to the following example.

[0067] First, prior to processing by the product storage device 40, the purchase-restricted product is stored (displayed) in a lockable product storage cabinet 42, and the door is locked. The door of the product storage cabinet 42 may be provided with, for example, a biometric information acquisition unit and a code reader. Examples of the biometric information acquisition unit include an imaging device such as a camera capable of capturing facial images, iris images, etc., and sensors such as a fingerprint sensor and palm print sensor. Examples of the code reader include a QR code (registered trademark) reader capable of reading the QR code (registered trademark) on the permit.

[0068] Next, steps S1 to S4 are carried out in the same manner as steps S1 to S4 in the first embodiment (purchase permission determination step). Specifically, for example, first, the user causes a QR code (registered trademark) reader installed near the door of the product storage cabinet 42 to read the QR code (registered trademark) on the permit. The QR code (registered trademark) reader generates read information by reading the QR code (registered trademark) on the permit and transmits the read information to the product storage device 40. Next, the user captures a facial image or the like using the biometric information acquisition unit installed on the door of the product storage cabinet 42 and transmits the image to the product storage device 40. The product storage device 40 authenticates the user by comparing the authentication standard information extracted from the read information with the biometric information and determines whether the user can purchase the restricted purchase product.

[0069] Then, for example, when the purchase eligibility determination unit 10 determines that the authenticated person is able to purchase the purchase-restricted product, the unlocking control unit 41 unlocks the product storage cabinet (S41, unlocking control step). According to the product storage device 40 of this embodiment, for example, the locked state of the product storage cabinet 42 in which the purchase-restricted product is stored can be unlocked depending on whether the user is eligible to purchase the product. Therefore, according to the product storage device 40 of this embodiment, only those who are eligible to purchase the purchase-restricted product (e.g., adults in the case of selling alcoholic beverages) can open the product storage cabinet 42, and those who are not eligible to purchase the purchase-restricted product (e.g., minors in the case of selling alcoholic beverages) cannot open the product storage cabinet 42. Therefore, the product storage device 40 of this embodiment can be suitably used, for example, when displaying purchase-restricted products such as alcoholic beverages at an unmanned sales counter or the like.

[0070] The unlocking control unit 41 may further unlock the product storage unit 42 if it is determined that the person to be authenticated is the manager of the product storage unit 42. The manager determination may be performed by, for example, the purchase eligibility determination unit 10 of the product storage device 40, or a separate manager authentication unit may be provided. The manager determination may be performed, for example, by previously linking the personal identification information of the manager with manager attribute information as the authentication standard information. Specifically, the purchase eligibility determination unit 10 or the manager authentication unit may, for example, acquire the personal identification information of the manager and the identification information of the person to be authenticated, and verify whether the person to be authenticated is the manager by comparing the personal identification information of the manager with the identification information of the person to be authenticated. The acquisition of the personal identification information of the manager, the acquisition of the identification information of the person to be authenticated, and authentication of the manager may be performed in the same manner as in steps S1 to S3 of the first embodiment, except that the personal identification information of the manager is acquired instead of the authentication standard information, and the personal identification information of the manager is compared with the identification information of the person to be authenticated.

[0071] In the product storage method of this embodiment, an example has been described in which S1 to S4 and S41 are executed sequentially, but the present invention is not limited to this. Specifically, in the present invention, S1 and S2 may be executed upstream of S3, and S1 and S2 may be executed simultaneously or separately. In the latter case, the order of execution is not particularly limited and is arbitrary.

[0072] [Embodiment 5] The fifth embodiment is an example of a sales outlet of the present invention.

[0073] The sales outlet of the present invention is characterized by including, for example, at least one selected from the group consisting of the purchase eligibility determination device, payment device, and product storage device of the present invention, and other configurations and conditions are not limited in any way. Since the sales outlet of the present invention includes at least one selected from the group consisting of the purchase eligibility determination device, payment device, and product storage device of the present invention, it is possible to determine, for example, whether a purchase-restricted product can be sold. The sales outlet may be in the form of, for example, a store or a vending machine. It is preferable that the sales outlet of the present invention is, for example, an unmanned sales outlet.

[0074] The store may be, for example, a store (so-called kiosk) located in a facility such as an apartment building, office building, station, factory, university, or hospital, and is preferably one that allows customers to pay for and pay for products without the need for a store clerk. The store may be, for example, an unmanned store with no clerk on-site, or a manned store.

[0075] The sales outlet of this embodiment may have an imaging device such as a surveillance camera installed at the entrance / exit, for example. In this case, for example, a purchase acceptance determination device, a payment device, or a product storage device in the sales outlet may acquire a facial image of the customer captured by the surveillance camera as identification information of the person to be authenticated.

[0076] The method for determining whether a purchase-restricted product can be purchased, the payment method, and the product storage method at the sales outlet of the present invention are, for example, similar to the descriptions of the purchase eligibility determination device, payment device, and product storage device of the present invention, and the descriptions therein can be used.
