Description

Technical Field

[0001] Embodiments of the present invention relate to an electronic money processing device and a program.

Background Art

[0002] In a self-checkout operated by a customer, when an error occurs, a store clerk is called. The store clerk checks the content of the error and responds in a manner corresponding to the error content.

[0003] In the case of settlement using a barcode recording a one-time authentication code that can be displayed on a customer's terminal, an authentication error based on the authentication code may occur. For example, a higher-level server communicating with the self-checkout checks the authentication code input to the self-checkout based on the barcode reading. After successful authentication based on the authentication code, the customer may perform operations such as changing the screen of the terminal or the settlement may not be completed within a certain period of time. In such cases, an authentication error may occur. The customer needs to display the reissued barcode on the terminal and input the authentication code to the self-checkout again, but since they cannot grasp the necessity of the input, it finally results in an error when the settlement is performed. After解除 the error, the store clerk needs to return to the screen operated by the customer and prompt the customer to read the barcode again.

[0010] The information for transactions in the store includes information on electronic money used in transactions in the store. Electronic money is a mechanism for electronically exchanging money. Electronic money can withdraw the amount of payment by payment. Electronic money can deposit a specified amount by charging.

[0011] The information processing system S includes a self-checkout 1, a charging machine 2, an electronic money server 3, an application server 4, and a user terminal 5. The self-checkout 1 and the charging machine 2 are devices in the store. Each device included in the information processing system S is communicably connected to each other via a network NW. The network NW includes one or more networks such as the Internet, a mobile communication network, and a LAN (Local Area Network). The LAN may be a wireless LAN or a wired LAN. The information processing system S is an example of an information processing system including at least two devices.

[0012] The self-checkout 1 is a device that processes transactions in the store. The self-checkout 1 has a product registration function and an accounting function, and is a device capable of operating product registration and accounting by a customer. Processing a transaction can include processing product registration. Processing a transaction can include processing accounting. The self-checkout 1 is an example of a transaction processing device that processes transactions.

[0013] Product registration is the registration of products before accounting for transactions. The registered products are also called registered goods. Accounting is the payment for transactions after product registration. Accounting includes the meaning of settlement. Payment methods for accounting in transactions include offline settlement and online settlement.

[0014] Offline settlement is an accounting method that does not require the self-checkout 1 to cooperate with other devices via the network NW. For example, offline settlement is accounting using cash, gift certificates, etc. A gift certificate is a certificate that circulates in a form similar to cash currency. For example, gift certificates include various types such as product vouchers, gift vouchers, rice vouchers, beer vouchers, shareholder privilege vouchers, regional revitalization vouchers, and coupons, but are not limited to these. Note that gift certificates include physical gift certificates and digitized gift certificates.

[0015] Online settlement is an accounting method that the self-checkout 1 executes in cooperation with other devices via the network NW.

[0018] Electronic money server 3 is a device that manages electronic money. Electronic money server 3 authenticates electronic money based on an authentication code related to the electronic money. Hereafter, "authentication" refers to the authentication of electronic money based on the authentication code. The authentication code is a code issued by application server 4 for authentication. The authentication code is a one-time authentication code. A one-time authentication code is an authentication code that is valid only temporarily. The start of the validity period of the authentication code is the time of issuance of the authentication code. The end of the validity period of the authentication code is the earlier of either a certain period of time elapsed since the issuance of the authentication code, or the time when a new authentication code is issued after the issuance of the authentication code. Electronic money server 3 maintains the latest authentication code in cooperation with application server 4 each time an authentication code is issued by application server 4.

[0019] The electronic money server 3 receives a one-time code from the self-checkout register 1 or the charging machine 2, as described below, and checks the authentication code contained in the received one-time code. Hereinafter, the authentication code contained in the received one-time code will also be referred to as the received authentication code. The received authentication code is the authentication code entered into the self-checkout register 1 or the charging machine 2. The electronic money server 3 authenticates based on the received authentication code and the stored authentication code, and determines the authentication result based on the received authentication code. If the received authentication code matches the stored authentication code, the electronic money server 3 determines the authentication result to be successful. If the received authentication code does not match the stored authentication code, the electronic money server 3 determines the authentication result to be an authentication error. An authentication error is an authentication code error because the received authentication code is not the latest authentication code.

[0020] App Server 4 is a device that manages the electronic money application. The electronic money application is an application for electronic money that can be used on the user terminal 5.

A one-time barcode is a barcode that records a one-time code including the issued authentication code and the customer's identification code. The customer's identification code is a code that uniquely identifies the customer as an electronic money member. A one-time code is a temporarily valid code. Since a one-time code includes an authentication code, the validity period of the one-time code is the same as the validity period of the authentication code. A one-time code is an example of a code that includes an authentication code. A one-time barcode is an example of a code symbol on which a one-time code is recorded. Based on the issuance of the authentication code, App Server 4 outputs information to the user terminal 5 for displaying the one-time barcode.

[0021] User terminal 5 is a terminal used by the customer. For example, user terminal 5 is a portable terminal such as a smartphone or tablet. User terminal 5 displays a one-time barcode using the electronic money application based on information for displaying a one-time barcode received from the application server 4.

[0066] The processing circuit 10 receives the input one-time code (ACT 101). ACT 101 may also be processed by the reception means 101. In ACT 101, for example, the processing circuit 10 receives the input one-time code using the reading device 14. Here, the customer has the reading device 14 read the one-time code recorded in the one-time barcode displayed on the user terminal 5. The one-time code recorded in the one-time barcode is entered into the self-checkout register 1 based on the reading by the reading device 14. Since the one-time code includes an authentication code, receiving the one-time code is one example of receiving the authentication code.

[0067] The processing circuit 10 stores the input one-time code in the main memory 11. Here, the processing circuit 10 is described as storing the one-time code in the main memory 11, but it may also store the one-time code in the storage 12. Each time the processing circuit 10 receives an input one-time code, it updates the one-time code stored in the main memory 11 with the input one-time code. In this way, the main memory 11 stores the most recently input one-time code.

[0068] Processing circuit 10 processes product registration (ACT102). In ACT102, for example, processing circuit 10 processes product registration for each product that is the subject of the transaction. Based on the completion of product registration, the processing circuit 10 displays the payment method selection screen IAA on the display device 16 (ACT103). ACT103 may also be processed by the display processing means 102. The processing circuit 10 receives the customer's operation of the "electronic money" button BAA (ACT 104). ACT 104 may also be processed by the reception means 101.

[0069] The processing circuit 10 outputs a request for checking the electronic money balance to the electronic money server 3 based on the customer's operation of the "electronic money" button BAA (ACT 105). ACT 105 may also be processed by the output means 103. The request for checking the electronic money balance includes the most recently entered one-time code stored in the main memory 11. The processing circuit 10 displays the authentication screen IAB on the display device 16 based on the output of the request for checking the electronic money balance (ACT106). ACT106 may also be processed by the display processing means 102.

[0070] The processing circuit 10 obtains the authentication result (ACT 107). ACT 107 may also be processed by the acquisition means 104. In ACT 107, for example, the processing circuit 10 obtains the authentication result from the electronic money server 3 as a response to a request for checking the balance of the electronic money. Here, the electronic money server 3 authenticates based on the authentication code contained in the received one-time code and the stored authentication code, and determines the authentication result. If the electronic money server 3 determines the authentication result to be an authentication error, it outputs an authentication result indicating the authentication error to the self-checkout register 1. If the electronic money server 3 determines the authentication result to be successful, it performs an electronic money balance inquiry. Once the electronic money server 3 has completed the electronic money balance inquiry, it outputs an authentication result indicating successful authentication and information indicating the electronic money balance to the self-checkout register 1.

[0071] The processing circuit 10 determines whether the authentication result is successful (ACT108). If the authentication result is successful (ACT108, YES), the process transitions from ACT108 to ACT114. If the authentication result is an authentication error (ACT108, NO), the process transitions from ACT108 to ACT109.

[0072] The processing circuit 10 causes the authentication error screen IAC to be displayed on the display device 16 (ACT109). ACT109 may also be processed by the display processing means 102. The processing circuit 10 determines which button was pressed by the customer on the authentication error screen IAC (ACT110). If the customer pressed the "Read Again" button BAB (ACT110, YES), the process transitions from ACT110 to ACT111. If the customer pressed the "Back" button BAC (ACT110, NO), the process transitions from ACT110 to ACT103. In ACT103, the processing circuit 10 displays the payment method selection screen IAA on the display device 16 based on the customer's operation of the "Back" button BAC.

The processing circuit 10 causes the authentication screen IAF to be displayed on the display device 16 based on the output of the request for electronic money payment (ACT117). ACT117 may also be processed by the display processing means 102.

[0078] The processing circuit 10 obtains the authentication result (ACT118). ACT118 may also be processed by the acquisition means 104. In ACT118, for example, the processing circuit 10 obtains the authentication result from the electronic money server 3 as a response to a request for electronic money payment. Here, if the electronic money server 3 determines the authentication result to be an authentication error, it outputs an authentication result indicating the authentication error to the self-checkout register 1. If the electronic money server 3 determines the authentication result to be successful, it executes the electronic money payment. When the electronic money server 3 has completed the electronic money payment, it outputs an authentication result indicating successful authentication and information indicating payment completion to the self-checkout register 1.

[0079] The processing circuit 10 determines whether the authentication result is successful (ACT119). If the authentication result is successful (ACT119, YES), the process ends. If the authentication result is an authentication error (ACT119, NO), the process transitions from ACT119 to ACT120.

[0080] The processing circuit 10 causes the authentication error screen IAG to be displayed on the display device 16 (ACT120). ACT120 may also be processed by the display processing means 102. The processing circuit 10 determines which button was pressed by the customer on the authentication error screen IAG (ACT121). If the customer pressed the "Read Again" button BAF (ACT121, YES), the process transitions from ACT121 to ACT122. If the customer pressed the "Back" button BAG (ACT121, NO), the process transitions from ACT121 to ACT103. In ACT103, the processing circuit 10 displays the payment method selection screen IAA on the display device 16 based on the customer's operation of the "Back" button BAG.

[0081] The processing circuit 10 displays the reading screen IAH on the display device 16 (ACT122) based on the customer's operation of the "Read Again" button BAF. ACT122 may also be processed by the display processing means 102. The processing circuit 10 sets the reading mode of the reading device 14 to the first reading mode (ACT123) based on the customer's operation of the "Scan Again" button BAF. ACT123 may also be performed by the setting means 105. This allows the self-checkout 1 to set the reading mode of the reading device 14 to the first reading mode at the moment the one-time barcode is held over the reading device 14. The self-checkout 1 can easily read the one-time code from the one-time barcode displayed on the user terminal 5 held over the reading device 14.

[0082] The processing circuit 10 receives the input one-time code (ACT124). ACT124 may also be processed by the reception means 101. The processing of ACT124 is the same as the processing of ACT101. The processing circuit 10 processes ACT 116 based on the input one-time code. In this case, the request for electronic money payment includes the most recently input one-time code stored in the main memory 11.

ACT305 may also be processed by the display processing means 202. The processing circuit 20 receives the customer's input to the "one-time barcode" button BCD (ACT306). ACT306 may also be processed by the reception means 201.

[0134] The processing circuit 20 displays the reading screen ICD on the display device 26 based on the customer's operation of the "one-time barcode" button BCD (ACT307). ACT307 may also be processed by the display processing means 202. Furthermore, the processing circuit 20 may set the reading mode of the reading device 24 to the first reading mode based on the customer's operation of the "One-Time Barcode" button BCD. This allows the charging machine 2 to set the reading mode of the reading device 24 to the first reading mode at the moment the one-time barcode is held over the reading device 24. The charging machine 2 can then easily read the one-time code from the one-time barcode displayed on the user terminal 5 held over the reading device 24.

[0135] The processing circuit 20 receives the input one-time code (ACT308). ACT308 may also be processed by the reception means 201. In ACT308, for example, the processing circuit 20 receives the input one-time code using the reading device 24. Here, the customer has the reading device 24 read the one-time code recorded in the one-time barcode displayed on the user terminal 5. The one-time code recorded in the one-time barcode is input to the charging machine 2 based on the reading by the reading device 24.

[0136] The processing circuit 20 stores the input one-time code in the main memory 21. Here, the processing circuit 20 is described as storing the one-time code in the main memory 21, but it may also store the one-time code in the storage 22. Each time the processing circuit 20 receives an input one-time code, it updates the one-time code stored in the main memory 21 with the input one-time code. In this way, the main memory 21 stores the most recently input one-time code.

[0137] The processing circuit 20 outputs a request for checking the electronic money balance to the electronic money server 3 based on the input one-time code (ACT309). ACT309 may also be processed by the output means 203. The request for checking the electronic money balance includes the most recently input one-time code stored in the main memory 21. The processing circuit 20 causes the authentication screen ICE to be displayed on the display device 26 (ACT310) based on the output of the request for checking the electronic money balance. ACT310 may also be processed by the display processing means 202.

[0138] The processing circuit 20 obtains the authentication result (ACT311). ACT311 may also be processed by the acquisition means 204. In ACT311, for example, the processing circuit 20 obtains the authentication result from the electronic money server 3 as a response to a request for checking the balance of the electronic money. Here, if the electronic money server 3 determines that the authentication result is an authentication error, it outputs an authentication result indicating the authentication error to the charging machine 2. If the electronic money server 3 determines that the authentication result is successful, it performs an electronic money balance inquiry. When the electronic money server 3 has completed the electronic money balance inquiry, it outputs an authentication result indicating successful authentication and information indicating the electronic money balance to the charging machine 2.

[0139] The processing circuit 20 determines whether the authentication result is successful (ACT312). If the authentication result is successful (ACT312, YES), the process transitions from ACT312 to ACT313. The processing circuit 20 accepts the customer's selection of the charge amount (ACT313). The processing circuit 20 accepts the insertion of cash into the change machine 28 to settle the charge amount. The process transitions from ACT313 to ACT318.

[0140] If the authentication result is not successful (ACT312, NO), the process transitions from ACT312 to ACT314. The processing circuit 20 determines whether the authentication result is an authentication error (ACT314). If the authentication result is not an authentication error (ACT314, NO), the process transitions from ACT314 to ACT315. In this case, instead of the authentication result, the processing circuit 20 obtains error information from the electronic money server 3, such as inquiry NG or card judgment NG, which is different from the authentication result. The processing circuit 20 performs other processing in response to errors such as query failure or card judgment failure (ACT315).

[0141] If the authentication result is an authentication error (ACT314, YES), the process transitions from ACT314 to ACT316. The processing circuit 20 causes the authentication error screen ICF to be displayed on the display device 26 (ACT316). ACT316 may also be processed by the display processing means 202. The processing circuit 20 determines which button was operated by the customer on the authentication error screen ICF (ACT317). If the customer operates the "Scan Again" button BCE (ACT317, YES), the process transitions from ACT317 to ACT307. In ACT307, the processing circuit 20 displays the reading screen ICD on the display device 26 based on the customer's operation of the "Scan Again" button BCE. The processing circuit 20 may also set the reading mode of the reading device 24 to the first reading mode based on the customer's operation of the "Scan Again" button BCE. This allows the charging machine 2 to set the reading mode of the reading device 24 to the first reading mode at the moment the one-time barcode is held over the reading device 24. The charging machine 2 can easily read the one-time code from the one-time barcode displayed on the user terminal 5 held over the reading device 24.

[0142] If the customer operates the "Back" button BCF (ACT317, NO), the process transitions from ACT317 to ACT301. In ACT301, the processing circuit 20 displays the start screen ICA on the display device 26 based on the customer's operation of the "Back" button BCF.

[0143] Figure 17 is a flowchart illustrating the electronic money charging process performed by the charging machine 2.

[0144] The processing circuit 20 outputs a request for charging electronic money to the electronic money server 3 (ACT318) based on an operation that authorizes the charging of electronic money. ACT318 may also be processed by the output means 203. The request for charging electronic money includes the most recently entered one-time code stored in the main memory 21. The processing circuit 20 displays the authentication screen ICG on the display device 26 based on the output of the request for charging electronic money (ACT319). ACT319 may also be processed by the display processing means 202.

[0145] The processing circuit 20 obtains the authentication result (ACT320). ACT320 may also be processed by the acquisition means 204. In ACT320, for example, the processing circuit 20 obtains the authentication result from the electronic money server 3 as a response to a request for charging electronic money. Here, if the electronic money server 3 determines that the authentication result is an authentication error, it outputs an authentication result indicating the authentication error to the charging machine 2. If the electronic money server 3 determines that the authentication result is successful, it performs the electronic money charging. When the electronic money server 3 has completed the electronic money charging, it outputs an authentication result indicating successful authentication and information indicating the completion of charging to the charging machine 2.

[0146] The processing circuit 20 determines whether the authentication result is successful (ACT321). If the authentication result is successful (ACT321, YES), the process ends. If the authentication result is an authentication error (ACT321, NO), the process transitions from ACT321 to ACT322.

[0147] The processing circuit 20 causes the authentication error screen ICH to be displayed on the display device 26 (ACT322). ACT322 may also be processed by the display processing means 202. The processing circuit 20 determines which button was pressed by the customer on the authentication error screen ICH (ACT323). If the customer pressed the "Read Again" button BCG (ACT323, YES), the process transitions from ACT323 to ACT324. If the customer pressed the "Back" button BCH (ACT323, NO), the process transitions from ACT323 to ACT301. In ACT301, the processing circuit 20 displays the start screen ICA on the display device 26 based on the customer's operation of the "Back" button BCH.

[0148] The processing circuit 20 displays the reading screen ICI on the display device 26 (ACT324) based on the customer's operation of the "Scan Again" button BCG. ACT324 may also be processed by the display processing means 202. The processing circuit 20 may also set the reading mode of the reading device 24 to the first reading mode based on the customer's operation of the "Scan Again" button BCG. This allows the charging machine 2 to set the reading mode of the reading device 24 to the first reading mode at the moment the one-time barcode is held over the reading device 24. The charging machine 2 can easily read the one-time code from the one-time barcode displayed on the user terminal 5 held over the reading device 24. The processing circuit 20 receives the input one-time code (ACT325). ACT325 may also be processed by the reception means 201. The processing of ACT325 is the same as the processing of ACT308.

[0149] The processing circuit 20 processes ACT318 based on the input one-time code. In this case, the request for charging electronic money includes the most recently input one-time code stored in the main memory 21.

[0150] As described above, if the electronic money processing device is found to be an authentication error, it can display an authentication error screen on the display device that prompts the user to enter a one-time code. Here, while operating the electronic money processing device, the customer may unintentionally display a one-time barcode on the user terminal 5 after successful authentication. When the one-time barcode is updated, the authentication code most recently entered into the electronic money processing device will no longer match the authentication code held in the electronic money server 3. Therefore, an authentication error may occur. Also, the authentication code becomes invalid after a certain period of time has elapsed since its issuance. Therefore, an authentication error may occur. The electronic money processing device can guide the customer to resolve the authentication error themselves by displaying an authentication error screen that prompts them to enter a one-time code. Therefore, the electronic money processing device does not degrade the customer's usability when an authentication error occurs. Since the customer can resolve the authentication error themselves, the burden on the customer, such as calling a store employee or waiting for an employee to come, is reduced. The customer can operate the electronic money processing device smoothly. On the store side, even if an authentication error occurs in the electronic money processing device, an employee is not called. Since the employee does not need to intervene in the authentication error, the burden on the employee is reduced.
