[Figure 6] This is the first example of the display on the customer-side display unit 103. [Figure 7] This is a second example of the display on the customer-side display unit 103. [Figure 8] This is a third example of the display on the customer-side display unit 103. [Modes for carrying out the invention]

[0008] Figure 1 shows an example configuration of a sales system 1 according to an embodiment of the present invention. The sales system (also referred to as a product sales data processing system or product data processing system) 1 can be introduced, for example, in supermarkets, convenience stores, drugstores, home centers, consumer electronics retailers, etc. As shown in Figure 1, the sales system 1 includes a registration and settlement device 10, a registration device 20, a settlement device 21, a transaction status management device 70, a store controller 80, and a headquarters server 90. The registration and settlement device 10, registration device 20, settlement device 21, transaction status management device 70, and store controller 80 are installed inside the store. These are connected so that they can communicate via a LAN (which may be wired or wireless). The headquarters server 90 is installed outside the store (for example, at the head office or a data center). The devices installed inside the store (registration and settlement device 10, registration device 20, settlement device 21, transaction status management device 70, store controller 80) and the devices installed outside the store (headquarters server 90) can communicate with each other (either directly or via the store controller 80).

[0009] The registration and payment device 10 is a device (a so-called face-to-face semi-self-service device) that performs registration processing based on the actions of the store clerk and performs payment processing based on the actions of the customer. Details of the registration and payment device 10 will be described later. Although Figure 1 shows one registration and payment device 10, there may be two or more registration and payment devices 10.

[0010] The registration device 20 is a device that performs registration processing based on the actions of a store employee. The payment device 21 is a device that performs payment processing based on the actions of a customer, using the registration information from the registration device 20. The registration device 20 and the payment device 21 together constitute a so-called semi-self-service system.

[0011] The registration device 20 includes, for example, a CPU, a storage unit, a store employee display unit (touch display), a customer display unit (touch display), a scanner unit, a communication unit, and a printing unit. The communication unit of the registration device 20 transmits the registration information generated in the registration process to the settlement device 21 (for example, transmitted to the settlement device 21 via the store controller 80, or transmitted to the settlement device 21 without going through the store controller 80). The registration device 20 may also include a key operation unit, an audio output unit, and a cash settlement unit (or drawer).

[0012] The payment device 21 comprises a CPU, a memory unit, a customer-side display unit (touch display), a scanner unit, a non-cash payment unit, a cash payment unit, a communication unit, a printing unit, an audio output unit, an imaging unit (camera), and a light-emitting unit. The communication unit of the payment device 21 receives registration information transmitted by the registration device 20 (for example, received via the store controller 80, or received without going through the store controller 80). The communication unit of the payment device 21 also transmits transaction information (described later) generated during the payment process to the headquarters server 90 (for example, transmitted to the headquarters server 90 via the store controller 80, or transmitted to the headquarters server 90 without going through the store controller 80). The payment device 21 may also include a store employee-side operation unit (touch display) and a human presence sensor unit (infrared sensor, etc.).

[0013] Although Figure 1 shows one registration device 20, there may be two or more registration devices 20. Although Figure 1 shows two settlement devices 21, there may be one or three or more settlement devices 21. The number of settlement devices 21 may be the same as the number of registration devices 20, but it is preferable that there be more settlement devices 21 than registration devices 20.

[0014] The transaction status management device 70 is a device used by store employees. The transaction status management device 70 manages other devices (such as the transaction status of other devices). For example, the transaction status management device 70 monitors and controls the registration and settlement device 10 (such as the operation status, processing status, and functioning status of the registration and settlement device 10) and the settlement device 21 (such as the operation status, processing status, and functioning status of the settlement device 21). In addition, the transaction status management device 70 monitors customers operating the registration and settlement device 10 and the settlement device 21 (such as customer operations and actions).

[0015] The transaction status management device 70 comprises at least a CPU, a storage unit, a display unit, an operation unit, and a communication unit. The operation unit may be a keyboard, mouse, etc. The display unit may be a touch display (i.e., it may also serve as the operation unit). If the transaction status management device 70 is equipped with a display unit (touch display) that also serves as the operation unit, it does not need to be equipped with a keyboard, mouse, etc.

[0016] The store controller 80 is a server responsible for communicating information between devices installed inside the store and devices installed outside the store. For example, the store controller 80 may transmit the product master (described later) received from the headquarters server 90 to each device inside the store (e.g., the registration and settlement device 10, registration device 20, settlement device 21, transaction status management device 70, etc.). The store controller 80 may also transmit transaction information received from the registration and settlement device 10 or settlement device 21 to the headquarters server 90. The store controller 80 comprises at least a CPU, a storage unit, and a communication unit.

[0017] Head office server 90 is installed outside the store (for example, at the head office, a data center, or the like). The head office server 90 stores, for example, a product master and a transaction file (described later). For example, the head office server 90 transmits the product master to each device in the store (for example, the registration and settlement device 10, the registration device 20, the settlement device 21, the transaction status management device 70, etc.) (for example, transmits via the store controller 80, or transmits without going through the store controller 80). The head office server 90 also receives transaction information generated by the registration and settlement device 10 and the settlement device 21 (for example, receives via the store controller 80, or receives without going through the store controller 80). The head office server 90 stores the received transaction information in the transaction file. The head office server 90 includes at least a CPU, a storage unit, and a communication unit. The head office server 90 may be a cloud server. The head office server 90 may be configured from a plurality of servers.

[0018] Devices other than the above-described devices may be installed in the store. For example, a registration and settlement device 30 that executes registration processing and settlement processing based on operations by a store clerk may be installed. A registration and settlement device 40 (so-called full-self device) that executes registration processing and settlement processing based on operations by a customer may be installed. Similar to the registration and settlement device 10, an operation mode (face-to-face semi-self mode) that executes registration processing based on operations by a store clerk and executes settlement processing based on operations by a customer, and similar to the registration and settlement device 40, a registration and settlement device 50 that can switch between an operation mode (full-self mode) that executes registration processing and settlement processing based on operations by a customer may be installed. In addition, a portable registration terminal (portable terminal) 60 (a terminal that can be attached to a shopping cart, a terminal configured integrally with a shopping cart, etc., not shown) that executes registration processing based on operations by a customer in the product sales floor may be operated, and a settlement device 61 that acquires registration information from the portable registration terminal 60 and executes settlement processing based on operations by a customer may be installed.

[0019] Figure 2 is an example of the external appearance of the registration and settlement device 10. Hereinafter, the configuration shown in Figure 2 will be described with reference to the external appearance shown in Figure 2. In Figure 2, the front side is the customer side, and the far side is the store clerk side.

[0020] The registration and settlement apparatus 10 includes a CPU 101 (not shown), a storage unit 102 (not shown), a store clerk side display unit 110 (see FIG. 2), a customer side display unit 103 (see FIG. 2), a store clerk side scanner unit (store clerk side product registration unit) 112 (see FIG. 2), a customer side scanner unit (customer side product registration unit) 104 (see FIG. 2), a payment terminal (cashless payment unit) 105 (see FIG. 2), a change banknote and coin machine (cash payment unit) 106 (see FIG. 2), a printing unit 107 (see FIG. 2), a key operation unit 111 (not shown), a voice output unit 113 (not shown), a communication unit 114 (not shown), an imaging unit (camera) 115 (see FIG. 2), and a light emitting unit (notification unit) 116 (see FIG. 2). Although not illustrated, the registration and settlement apparatus 10 may be provided with a human sensor unit.

[0021] The CPU 101 controls the operation of the registration and settlement apparatus 10 by reading and executing a program stored in the storage unit 102. For example, the CPU 101 controls the entire transaction from product registration to settlement. That is, the CPU 101 executes (advances) the registration processing and the settlement processing.

[0022] The storage unit 102 is a general term for one or more various storage members (for example, those serving as memory or storage, such as RAM, ROM, hard disk, SSD (Solid State Drive), etc.). The storage unit 102 stores various types of information. For example, the storage unit 102 stores programs executed by the CPU 101, information referred to by the CPU 101 (for example, a product master), information generated by the CPU 101 (for example, transaction information), and the like.

[0023] The store clerk side scanner unit 112 optically reads various types of information. For example, the store clerk side scanner unit 112 scans a code attached to a product and reads a product code. In addition, the store clerk side scanner unit 112 reads a barcode printed on a receipt (a barcode obtained by encoding transaction identification information (described later)).

[0024] The customer-side scanner unit 104 optically reads various types of information. For example, the customer-side scanner unit 104 reads barcodes attached to membership cards, etc.

[0025] The employee-side display unit 110 is a touch display that shows various information to the operator (employee) and accepts operations from the operator. The customer-side display unit 103 is a touch display that shows various information to the operator (customer) and accepts operations from the operator.

[0026] The payment terminal 105 is a payment mechanism for non-cash payments (e.g., credit card payments, electronic money payments, etc.). The payment terminal 105 may be a separate payment terminal from the registration and settlement device 10. The payment terminal 105 includes, for example, a reading unit, a communication unit (a communication unit that communicates with the registration and settlement device 10, a communication unit that communicates with an external server such as a credit server that performs credit card payments), an operation unit, and a display unit.

[0027] The change dispenser 106 is a cash payment mechanism. The change dispenser 106 has an input slot for banknotes and coins, and an output slot for banknotes and coins. The change dispenser 106 detects the currency inserted into the input slot, identifies the number of bills of each denomination inserted, calculates the amount inserted, calculates the change amount which is the difference between the inserted amount and the purchase amount, and dispenses the change from the output slot. The insertion of banknotes and coins and the removal of change may be detected by sensors.

[0028] The printing unit 107 prints and issues various media (e.g., receipts, coupons). The removal of media may be detected by a sensor. The key operation unit 111 consists of one or more buttons (hard buttons) for operation by store staff. The voice output unit 113 outputs voice (e.g., confirmation sound, warning sound, voice guidance, etc.).

[0029] The communication unit 114 transmits and receives information with other devices. For example, the communication unit 114 receives product master data from the store controller 80 (or headquarters server 90). The communication unit 114 also transmits transaction information to the store controller 80 (or headquarters server 90).

[0030] The imaging unit 115 captures images of the customer's actions, such as scanning products and inserting cash into the change dispenser 106 (or withdrawing cash from the change dispenser 106). The light-emitting unit 116 provides various information through light emission.

[0031] Figure 3 is an explanatory diagram illustrating the product master. The product master (also called the basic product file) stored in sales system 1 stores basic product information. The product master (i.e., basic product information) has data items such as product code, product name, base price, tax amount, and tax-inclusive price, as shown in Figure 3.

[0032] The product code is identification information that identifies each product. The product name is the name of the product. The base price is the price of the product excluding consumption tax. The tax amount is the consumption tax amount for the product. The price including tax is the price of the product including consumption tax.

[0033] In other words, the product master stores basic product information as a record for each product, and within the basic product information for each product, the product name, base price, tax amount, and tax-inclusive price are stored, associated with the product code of that product. For example, in the basic product information for symbol a in Figure 3, the product name "AAA", base price "441 (yen)", tax amount "44 (yen)", and tax-inclusive price "485 (yen)" are stored, associated with the product code "49...".

[0034] According to the basic product information for code a, product code "49..." is AAA, and the base price of the product is 441 yen, the tax is 44 yen, and the price including tax is 485 yen.

[0035] Figure 4 is an explanatory diagram illustrating a transaction file. The transaction file stored in the sales system 1 stores transaction information generated in the sales system 1 (for example, the registration and settlement device 10). The transaction file (i.e., transaction information) has data items such as transaction identification information, date and time, product 1, ..., product n, total (including tax), tax amount, and settlement type, as shown in Figure 4(A), for example.

[0036] Transaction identification information is identification information that identifies each transaction. For example, the registration and settlement device 10 may generate the transaction identification information (numbering or issuing a number if it is a number), or the headquarters server 90 may generate the transaction identification information based on a request from the registration and settlement device 10 and notify the registration and settlement device 10. The transaction identification information may be a combination of the transaction date, the device identification information of the device that processed the transaction, one or more store identification information if there are multiple stores, and a serial number.

[0037] The date and time is the transaction date and time (e.g., settlement date and time). Product X (where X is 1 to n) is the product information (product registration information) of the Xth product included in the transaction (the Xth product sold in the transaction), including the product code, product name, quantity, base price, and tax-inclusive price. The total is the total amount including consumption tax for the transaction (the total amount including consumption tax for all products). The tax amount is the consumption tax amount for the transaction (the total amount of consumption tax for all products). The payment type is information indicating the method of settlement (settlement) for the transaction. For example, payment type "K01" indicates cash payment, payment type "K02" indicates credit card payment, etc.

[0038] In other words, the transaction file stores transaction information as a record showing the details of each transaction. Each transaction's information is associated with the transaction identification information of that transaction and stores the following: Product 1, ..., Product n, Total (including tax), Tax amount, and Payment type. For example, Figure 4(B) shows the transaction information for one transaction. The transaction information in Figure 4(B) is associated with the transaction identification information "TXXXX" and stores the date and time "YYYYMMDDHHMM", Product 1 (Product code "49...", Product name "AAA", Quantity "1", Base price "441 (yen)", Tax amount "44 (yen)", Price including tax "485 (yen)"), Product 2 (Product code "49...", Product name) The following information is stored: "BBB", quantity "1", base price "318 (yen)", tax amount "32 (yen)", tax-inclusive price "350 (yen)", item 3 (item code "49...", item name "CCC", quantity "1", base price "489 (yen)", tax amount "49 (yen)", tax-inclusive price "538 (yen)"), total "1373 (yen)", tax amount "125 (yen)", payment type "K01 (cash)".

[0039] According to the transaction information in Figure 4(B), the transaction with transaction identification information "TXXXX" includes AAA (base price "441 yen", 1 unit, tax amount "44 yen", tax-inclusive price "485 yen"), BBB (base price "318 yen", 1 unit, tax amount "32 yen", tax-inclusive price "350 yen"), and CCC (base price "489 yen", 1 unit, tax amount "49 yen", tax-inclusive price "538 yen"), the total amount including consumption tax for this transaction is "1373 yen", the consumption tax amount for this transaction is "125 yen", and the settlement method for this transaction is cash payment.

[0040] (Return processing, product exchange processing) The registration and settlement device 10 is capable of performing a return process to return goods included in a settled transaction (goods that have been sold). Furthermore, the registration and settlement device 10 is capable of performing a product exchange process to exchange sold goods for other goods (registering other goods). The product exchange process encompasses both the return of sold goods and the registration of other goods as a single transaction. In other words, the registration and settlement device 10 can perform not only a simple return of sold goods, but also an exchange of sold goods for other goods as a single transaction (it can simply return sold goods or exchange sold goods for other goods). So, while the registration and settlement device 10 is described as performing registration and settlement processes, it is also capable of performing return and product exchange processes.

[0041] As described above, the product exchange process is a process that encompasses the return of a product already sold and the registration of another product as a single transaction. Therefore, the product exchange process can be considered to encompass the return process, or it can be considered a form of the return process (a form in which "registration of another product" is added to "return"). Alternatively, the return process can be considered a part of the product exchange process (the part related to "return").

[0042] (Original transaction, correction process, etc.) In the following explanation, a settled transaction in which a sold item is simply returned, or a settled transaction in which a sold item is exchanged for another item, may be referred to as the "original transaction." In other words, the "original transaction" is the term used for a settled transaction in which the items included in the transaction are simply returned or exchanged for another item.

[0043] Whether a sold item is simply returned or exchanged for another item, the details of the original transaction (including the items included in the original transaction) are corrected (changed) to reflect the return or exchange. In other words, the details of the original transaction are corrected (changed) by the return or exchange process. Therefore, in the following explanation, the return of a sold item or the exchange of a sold item for another item may be referred to as "transaction correction (transaction change)" or "item correction (item change)," while the return or exchange process may be referred to as "transaction correction process (transaction change process)," "item correction process (item change process)," or simply "correction process (change process)." In other words, the terms "transaction correction process (transaction change process)," "item correction process (item change process)," and "correction process (change process)" may also be general terms for return or exchange processes.

[0044] As mentioned above, the product exchange process is a process that encompasses the return of a product already sold as a single transaction and the registration of a different product. The registration of the different product constitutes a sale of that different product. If the sale from the registration of the product in the original transaction is considered the "initial sale," then the sale from the registration of the different product in the product exchange process corresponds to a "second sale." Therefore, the sale from the registration of the different product in the product exchange process (or the registration of a different product, or the exchange for a different product) may be called a "resale."

[0045] (Process for product exchange) Next, we will explain the process (flow) of the product exchange procedure, including the actions (operations, etc.) of people (customers, store clerks) and the operation of the registration and settlement device 10.

[0046] (Step 1) A customer who wishes to exchange an item (hereinafter simply referred to as "customer") requests an exchange from a store employee (hereinafter simply referred to as "store employee") operating the registration and settlement device 10. The store employee accepts the request for an exchange.

[0047] When making a request, the customer hands the store clerk the item to be returned, the item to be exchanged, and the receipt for the original transaction (the transaction including the returned item). The store clerk receives the returned item, the item to be exchanged, and the receipt for the original transaction, and accepts the request for the exchange.

[0048] The original transaction may be a transaction registered / settled in the said registration / settling device 10, a transaction registered / settled in another registration / settling device 10, or a transaction registered / settled in a device different from the registration / settling device 10 (for example, a transaction registered in registration device 20 and settled in settlement device 21).

[0049] The receipt for the original transaction has a barcode printed on it that encodes the transaction identification information of that original transaction. Alternatively, the receipt for the original transaction may also have the transaction identification information of that original transaction printed on it, either in place of or in addition to the barcode.

[0050] (Step 2) The store clerk displays the initial transaction correction screen (not shown) on the store clerk's side display unit 110 of the registration and settlement device 10. For example, the store clerk displays the initial transaction correction screen by operating a predetermined button (for example, a transaction correction button) that is operable on a predetermined screen (for example, a menu screen (not shown), an initial registration screen before registering one product item (not shown)) displayed on the store clerk's side display unit 110.

[0051] In other words, the registration and settlement device 10 displays the initial transaction correction screen on the employee-side display unit 110 based on a predetermined operation by the employee (operation of the transaction correction button).

[0052] The initial transaction correction screen is the initial screen for correction processing (return processing, product exchange processing). On the initial transaction correction screen, the store clerk selects a method for identifying the original transaction. The initial transaction correction screen displays two operable buttons: a scan button to identify the original transaction by scanning the barcode (a barcode encoding transaction identification information) printed on the receipt of the original transaction, and a manual input button to identify the original transaction by manually entering the transaction identification information printed on the receipt of the original transaction. A message is displayed instructing the user to operate either the scan button or the manual input button.

[0053] (Step 3) The store clerk operates the scan identification button on the initial transaction correction screen, and then the store clerk's scanner unit 112 scans the barcode printed on the receipt of the original transaction, causing the store clerk's display unit 110 to display the original transaction confirmation screen (not shown).

[0054] In other words, the registration and settlement device 10 displays the original transaction confirmation screen on the employee-side display unit 110 based on the employee's predetermined operation (operation of the scan identification button → scanning of the barcode).

[0055] Alternatively, the store clerk may operate the manual input button on the initial transaction correction screen to display the transaction identification information input screen (not shown) on the clerk's display unit 110, manually enter the transaction identification information on the transaction identification information input screen, and then display the original transaction confirmation screen on the clerk's display unit 110.

[0056] In other words, the registration and settlement device 10 may display a transaction identification information input screen on the employee-side display unit 110 based on a predetermined operation by the employee (operation of a manual input identification button), and may also display a original transaction confirmation screen on the employee-side display unit 110 based on a predetermined operation by the employee (manual input of transaction identification information).

[0057] The original transaction confirmation screen is a screen for confirming the original transaction. The original transaction confirmation screen displays the total amount of the original transaction for confirmation. For example, the registration settlement device 10 sends a transaction details acquisition request to the headquarters server 90, which includes transaction identification information obtained by reading a barcode (or transaction identification information obtained by manual input). Upon receiving the transaction details acquisition request, the headquarters server 90 refers to the transaction file and sends the transaction information of the transaction identified by the transaction identification information included in the transaction details acquisition request to the registration settlement device 10. Upon receiving the transaction information, the registration settlement device 10 displays the "total (tax included)" and other information included in the transaction information on the original transaction confirmation screen.

[0058] (Step 4) The store clerk checks the total amount of the original transaction displayed on the original transaction confirmation screen. If there are no problems (for example, if it matches the total amount printed on the receipt for the original transaction), the clerk operates the execute button displayed on the original transaction confirmation screen to display the simple return / exchange selection screen (not shown) on the clerk's display unit 110.

[0059] In other words, the registration and settlement device 10 displays a simple return / exchange selection screen on the employee-side display unit 110 based on a predetermined operation by the employee (operation of the execution button).

[0060] The simple return / exchange selection screen is a screen for selecting whether to simply return a sold item or exchange it for a different item. In other words, it is a screen that accepts a declaration of whether it is a simple return (a return without an exchange of goods) or a return with an exchange of goods. The simple return / exchange selection screen displays an operable simple return button for simply returning a sold item and an exchange button for exchanging a sold item for a different item, and a message is displayed prompting the user to operate either the simple return button or the exchange button.

[0061] (Step 5) The store clerk operates the exchange button on the simple return / exchange selection screen to display the return item specification screen (not shown) on the store clerk's display unit 110. In other words, the store clerk declares that the return involves an exchange of the product and displays the return item specification screen on the store clerk's display unit 110.

[0062] In other words, the registration and settlement device 10 displays a screen for specifying the returned items on the employee-side display unit 110 based on a predetermined operation by the employee (operation of the exchange button).

[0063] The Return Item Selection screen is a screen for selecting items to be returned. On the Return Item Selection screen, each item included in the original transaction is displayed in an operable (selectable) format, and a message for specifying the items to be returned is displayed. The registration settlement device 10, for example, displays information (product name, price, etc.) for each item (each sold item) included in the transaction information of the original transaction (transaction information received from the headquarters server 90 after sending a transaction details acquisition request to the headquarters server 90) in an operable format on the Return Item Selection screen.

[0064] (Step 6) The store clerk specifies the items to be returned on the return item selection screen (specifying all items if there are two or more items to be returned). Once the selection is complete, the clerk operates the "Complete" button displayed on the return item selection screen to display the exchange item registration screen (not shown).

[0065] In other words, the registration and settlement device 10 identifies the returned items (accepts the designation) based on a predetermined operation by the store clerk (operation of specifying the returned items), and displays the exchange item registration screen on the store clerk's display unit 110 based on a predetermined operation by the store clerk (operation of the completion button).

[0066] The exchange item registration screen is a screen that instructs you to register the item to be exchanged. The exchange item registration screen displays a message instructing you to register the item to be exchanged (by scanning the barcode attached to the item to be exchanged).

[0067] (Step 7) The store clerk scans the barcode attached to the exchange item using the store clerk's scanner unit 112 (scanning all items if there are two or more exchange items). After scanning, the clerk operates the completion button displayed on the exchange item registration screen to display the store clerk's payment screen (described later) on the store clerk's display unit 110. The completion button in Step 7 corresponds to the subtotal operation in the registration process.

[0068] In other words, the registration and settlement device 10 identifies (registers) the exchange items based on a predetermined operation by the store clerk (scanning the exchange items), and displays the store clerk's settlement screen on the store clerk's display unit 110 based on a predetermined operation by the store clerk (operating the completion button). The registration and settlement device 10 also displays the customer's settlement screen (described later) on the customer's display unit 103.

[0069] (Step 8) The customer confirms the amount on the payment screen (and makes a payment if necessary). If there are no problems (for example, if there are no issues with the amount or other details), they operate the "Finish button" displayed on the customer payment screen, receive any change, print and issue a receipt, and complete the product exchange process.

[0070] In other words, the registration and settlement device 10, based on the customer's predetermined operation (ultimately the operation of the "end" button), dispenses change if there is any, prints and issues a receipt, and completes the product exchange process. The receipt will include, for example, the transaction identification number, the amount of the returned product, the amount of the exchanged product, and the amount of payment if a payment has been made. The receipt for the original transaction received from the customer will be collected.

[0071] The registration and settlement device 10 may also print and issue the following three receipts: (a) to (c). (a) A receipt that can identify the returned item (b) Receipt for the original transaction after the update (original transaction after the return) (c) Receipt for resale (receipt that can identify the exchange item) (b) The receipt shall have the transaction identification number of the original transaction printed on it. (c) The receipt may have a new transaction identification number printed on it, either in place of or in addition to the transaction identification number of the original transaction.

[0072] The registration and settlement device 10 may also print and issue two receipts: one that serves as both receipt (a) and receipt (b), and another receipt (c).

[0073] Note that the steps from step 6 onwards described above are the procedure when the store clerk operates the exchange button in step 5 (declaring that it is a return involving an exchange of goods). However, if the store clerk operates the simple return button in step 5 (declaring that it is a return without an exchange of goods), the refund payment process proceeds. For example, the registration and settlement device 10 displays the refund amount on the customer-side display unit 103, and based on the customer's operation (for example, operating the "end button" displayed on the screen showing the refund amount), it pays out the refund amount, prints and issues a receipt, and completes the refund process. As with the case where the exchange button is operated, the receipt for the original transaction received from the customer is collected.

[0074] Next, we will explain the display on the customer-side display unit 103 of the registration and settlement device 10 during the product exchange process. Specifically, using Figures 5 to 8, we will explain three types of display examples (first display example, second display example, and third display example) as examples of the display on the customer-side display unit 103 during the product exchange process.

[0075] [Example 1] Figure 5 shows an example of the display on the employee-side display unit 110 and a first example of the display on the customer-side display unit 103. Figures 5(A) to 5(D) show a scenario in which a customer (customer K) has purchased one each of products "AAA", "BBB", and "CCC" in a completed transaction (the transaction information for this transaction is as shown in Figure 4(B)), and has requested to exchange product "CCC" for another product "DDD". The price of product "CCC" ("538 yen") < the price of product "DDD" ("680 yen") (see Figure 3).

[0076] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "DDD" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a settlement screen for store clerks as shown in Figure 5(A) on the store clerk-side display unit 110, and a settlement screen for customers as shown in Figure 5(B) on the customer-side display unit 103.

[0077] (Clerk's payment screen in Figure 5(A)) As shown in Figure 5(A), the cashier's payment screen includes a product area 101 and a payment area 102.

[0078] Product area 101 is an area that displays information about products. In Figure 5(A), information about product "AAA" included in the original transaction, information about product "BBB" included in the original transaction, information about product "CCC" included in the original transaction, and information about product "DDD" which is the replacement product are displayed. The information for product "CCC", which is the returned product, is crossed out with a double strikethrough. The word "Exchange" is displayed as the information for product "DDD", which is the replacement product.

[0079] Furthermore, regarding the display order of products in product area 101, returned products may be displayed in the same order as the details in the original transaction (maintaining the order of the details), and the replacement products may be displayed below the products of the original transaction (including returned products) (Display Mode 1), or returned products may be displayed at the very bottom among the products of the original transaction, and the replacement products may be displayed below the products of the original transaction (including returned products) (Display Mode 2).

[0080] If the returned item is product "BBB" and not product "CCC", the registration settlement device 10 will, in display mode 1, display product "AAA" at the top, product "BBB" with a double strikethrough as the second item, product "CCC" as the third item, and product "DDD" as the fourth item (also displaying the word "exchange"). In display mode 2, it will display product "AAA" at the top, product "CCC" as the second item, product "BBB" with a double strikethrough as the third item, and product "DDD" as the fourth item (also displaying the word "exchange").

[0081] The settlement area 102 is an area that displays information related to settlement. The settlement area 102 has display fields for "Number of items purchased (after correction)", "Subtotal (original transaction)", "Subtotal (after correction)", "Surplus / Deficit", "Amount received (deposit)", and "Change".

[0082] "Purchased Items (After Correction)" is the number of items purchased after correction (i.e., after the product exchange process). In Figure 5(A), the "Purchased Items (After Correction)" column shows "3 (items)" for products "AAA", "BBB", and "DDD". The "Subtotal (Original Transaction)" column shows the subtotal amount of the original transaction (i.e., before correction and before the product exchange process). In Figure 5(A), the "Subtotal (Original Transaction)" column displays the subtotal amount of "1373 (yen)" for products "AAA", "BBB", and "CCC". The "Subtotal (Corrected)" column shows the corrected subtotal amount. In Figure 5(A), the "Subtotal (Corrected)" column displays the subtotal amount of "1515 yen" for products "AAA", "BBB", and "DDD". "Surplus / Deficit" is the amount obtained by subtracting "Subtotal (Corrected)" from "Subtotal (Original Transaction)". In Figure 5(A), the "Surplus / Deficit" column shows "-142 (yen)", which is the result of subtracting "1515 (yen)" from "1373 (yen)". "Amount Received (Deposit)" refers to the amount received from customer K in the correction (the product exchange process) (the amount paid by customer K in the correction). The scene in Figure 5(A) is before receiving the deposit from customer K, and the amount received is "0 (yen)", but the "Amount Received (Deposit)" column is left blank. "Change" refers to the amount of change (payment amount) given to customer K in the correction (product exchange process). In the scene shown in Figure 5(A), the "Change" column is left blank. Further details will be provided later.

[0083] (Customer payment screen in Figure 5(B)) As shown in Figure 5(B), the customer settlement screen (which may also be called the customer settlement confirmation screen) includes an original transaction area 201 and a resale area 202.

[0084] In the original transaction area 201, in addition to the display field for the original transaction's products (indicated as b in the diagram), there are display fields for "Total," "Refund Amount," "Total After Refund," and "Refund Amount for Original Transaction."

[0085] The section displaying the original transaction's products is an area that displays information about the products in the original transaction. In Figure 5(B), information about product "AAA", product "BBB", and product "CCC" included in the original transaction are displayed. The information for product "CCC", which is a returned product, is crossed out with a double line.

[0086] Furthermore, regarding the display order of products in the product display section of the original transaction, returned products may be displayed in the same order as the details in the original transaction (displaying them while maintaining the order of the details) (display method 1), or returned products may be displayed at the bottom of the products in the original transaction (display method 2).

[0087] If product "BBB" is the returned product instead of product "CCC", the registration settlement device 10 will, in display mode 1, display product "AAA" at the top, product "BBB" with a double strikethrough as the second product, and product "CCC" as the third product. In display mode 2, it will display product "AAA" at the top, product "CCC" as the second product, and product "BBB" with a double strikethrough as the third product.

[0088] The "Total" column shows the subtotal amount of the original transaction. In Figure 5(B), the "Total" column displays the subtotal amount of "1373 (yen)" for products "AAA", "BBB", and "CCC". The "Refund Amount" is the total value of the returned items. In Figure 5(B), the "Refund Amount" column shows the value of the returned item "CCC," which is "538 yen." The "Total after refund" is the amount obtained by subtracting the "Refund Amount" from the "Total". In Figure 5(B), the "Total after refund" column shows "835 yen," which is the result of subtracting "538 yen" from "1373 yen." The "Refund Amount from Original Transaction" is the refund amount from the original transaction. In Figure 5(B), the "Refund Amount from Original Transaction" column shows the amount of "538 yen" for the returned item "CCC".

[0089] In the resale area 202, in addition to the display field for the exchanged items (symbol c in the diagram), there are display fields for "Total," "Temporary Deposit," "Shortfall," "Deposit (Received)," "Change," and "Total Refund."

[0090] The exchange item display area is the area that displays information about the exchange item. In Figure 5(B), information about the exchange item "DDD" is displayed.

[0091] "Total" is the total amount of the exchanged items (also called the total resale amount). In Figure 5(B), the "Total" column shows the amount of the exchanged item "DDD" as "680 (yen)". "Temporary holding" is the "refund amount (refund amount in the original transaction)" in the original transaction area 201. In other words, it is the total amount of the returned goods (refund amount in the original transaction). In Figure 5(B), "538 (yen)" is displayed in the "Temporary holding" column. The "shortfall" is the amount obtained by subtracting the "temporary deposit" from the "total". In Figure 5(B), the "shortfall" column shows "142 yen," which is the result of subtracting "538 yen" from "680 yen." "Deposit (Payment)" is the amount of money received from customer K in the correction (the product exchange process) (the amount paid by customer K in the correction). The scene in Figure 5(B) is before the deposit is received from customer K, so in Figure 5(B), "0 (yen)" is displayed in the "Deposit (Payment)" column. "Change" refers to the amount of change (payment amount) given to customer K in the correction (product exchange process). In Figure 5(B), the "Change" column is left blank. Further details will be provided later. The "Total Refund" is the sum of the "Refund Amount for Original Transaction" and the "Change." In the scenario shown in Figure 5(B), the "Total Refund" column is left blank, similar to the "Change" column. Further details will be provided later.

[0092] The customer settlement screen also includes a display field for "Original Transaction Refund Amount + Deposit" at the bottom of the original transaction area 201 and the resale area 202. The "Original Transaction Refund Amount + Deposit" field displays the sum of the "Original Transaction Refund Amount" from the original transaction area 201 and the "Deposit (Deposit)" from the resale area 202. In other words, it displays the total amount of the temporary deposit, which is the original transaction refund amount, and the deposit amount received as a deposit. In Figure 5(B), "538 yen" is displayed, which is "538 yen" plus "0 yen".

[0093] In the customer settlement screen in Figure 5(B) (and similarly in the customer settlement screens in Figures 5(D) and 6(A) to 6(C)), the field is labeled "Refund Amount for Original Transaction + Deposit," but other names may be used. For example, it may be labeled "Amount Received," as in Figures 7(A) to 7(E) and 8(A) to 8(E).

[0094] In the scenarios shown in Figures 5(A) and 5(B), when customer K deposits 200 yen (when 200 yen worth of cash is inserted into the change dispenser 106), the registration and settlement device 10 displays a settlement screen for the store clerk on the store clerk's display unit 110, as shown in Figure 5(C), and a settlement screen for the customer on the customer's display unit 103, as shown in Figure 5(D).

[0095] (Cash register screen for store staff in Figure 5(C)) In Figure 5(A), the "Deposits" column was blank, but in Figure 5(C), "200 (yen)" is displayed in the "Deposits" column. In Figure 5(A), the "Change" column was blank, but in Figure 5(C), "58 (yen)" is displayed in the "Change" column. Further details will be provided later.

[0096] (Customer payment screen in Figure 5(D)) In Figure 5(B), "0 (yen)" was displayed in the "Deposits (Deposits)" column, but in Figure 5(D), "200 (yen)" is displayed in the "Deposits (Deposits)" column. In Figure 5(B), the "Change" column was blank, but in Figure 5(D), "58 (yen)" is displayed in the "Change" column. Further details will be provided later. In Figure 5(B), the "Total Refund" column was blank, but in Figure 5(D), "596 (yen)" is displayed in the "Total Refund" column. Further details will be provided later. In Figure 5(B), the "Original Transaction Refund Amount + Deposit" column displayed "538 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "0 yen," which is the "Deposit (Deposit)" from resale area 202. However, in Figure 5(D), the "Original Transaction Refund Amount + Deposit" column displays "738 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "200 yen," which is the "Deposit (Deposit)" from resale area 202.

[0097] The sum of "Temporary Deposit (Refund Amount from Original Transaction)" and "Deposit (Received)" (the amount displayed in the "Refund Amount from Original Transaction + Received" column) is greater than or equal to the "Total (Total Resale Amount)," so the "End" button is displayed as operable. When customer K operates the "End" button, the registration settlement device 10 dispenses change ("58 yen"), prints and issues a receipt, and terminates the product exchange process.

[0098] Figure 6 shows a first example of the display on the customer-side display unit 103. Note that in Figure 6 (and similarly in Figures 7 and 8), the explanation of the cashier's payment screen on the cashier-side display unit 110 is omitted.

[0099] Figures 6(A) and 6(B) show a scenario in which a customer (Customer K) has purchased one unit each of products "AAA", "BBB", and "CCC" in a completed transaction, and has requested to exchange product "CCC" for another product "EEE". The price of product "CCC" ("538 yen") is greater than the price of product "EEE" ("400 yen") (see Figure 3).

[0100] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "EEE" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 6(A).

[0101] (Customer payment screen in Figure 6(A)) The display content in the original trading area 201 is the same as when the exchange item is the item "DDD" (Figures 5(B) and 5(D)).

[0102] In the resale area 202, in addition to the display field for the exchanged items (symbol c in the diagram), there are display fields for "Total," "Temporary Deposit," "Shortfall (Remaining Balance)," "Deposit (Received)," "Change," and "Total Refund."

[0103] The replacement item display section shows information about the replacement item, "EEE". The "Total" column displays the price of the exchange item, "EEE," which is "440 yen." The "Temporary Deposit" column displays "538 yen," which is the "Refund Amount (Refund Amount from Original Transaction)" for the original transaction area 201. In the "Shortfall (Remaining Balance)" column, "-98 yen" is displayed, which is the result of subtracting the "Temporary Deposit" of "538 yen" from the "Total" of "440 yen". It can also be said that this is the remaining balance after subtracting the "Total" from the "Temporary Deposit," hence the "98 yen" is displayed in parentheses. The "Deposits" column displays "0 (yen)". The "Change" column displays "98 (yen)". More details will follow. The "Total Refund" column displays "636 yen". Further details will be provided later. The "Original Transaction Refund Amount + Deposit" column displays "538 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "0 yen," which is the "Deposit (Deposit)" from resale area 202.

[0104] The sum of "Temporary Deposit (Refund Amount from Original Transaction)" and "Deposit (Received)" (the amount displayed in the "Refund Amount from Original Transaction + Received" column) is greater than or equal to "Total (Total Resale Amount)", so the "End" button is displayed as operable. When customer K operates the "End" button, the registration settlement device 10 dispenses change ("98 yen"), prints and issues a receipt, and terminates the product exchange process.

[0105] In the scenario shown in Figure 6(A), if customer K deposits 2 yen (inserts 2 yen worth of cash into the change dispenser 106), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103, as shown in Figure 6(B).

[0106] (Customer payment screen in Figure 6(B)) In Figure 6(A), "0 (yen)" was displayed in the "Deposits (Deposits)" column, but in Figure 6(B), "2 (yen)" is displayed in the "Deposits (Deposits)" column. In Figure 6(A), "98 yen" is displayed in the "Change" column, but in Figure 6(B), "100 yen" is displayed in the "Change" column. Further details will be provided later. In Figure 6(A), "Total Refund" was displayed as "636 yen," but in Figure 6(B), "Total Refund" is displayed as "638 yen." Further details will be provided later. In Figure 6(A), the "Original Transaction Refund Amount + Deposit" column displayed "538 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "0 yen," which is the "Deposit (Deposit)" from resale area 202. However, in Figure 6(B), the "Original Transaction Refund Amount + Deposit" column displays "540 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "2 yen," which is the "Deposit (Deposit)" from resale area 202.

[0107] The sum of "Temporary Deposit (Refund Amount from Original Transaction)" and "Deposit (Received)" (the amount displayed in the "Refund Amount from Original Transaction + Received" column) is greater than or equal to "Total (Total Resale Amount)", so the "End" button is displayed as operable. When customer K operates the "End" button, the registration settlement device 10 dispenses change ("100 (yen)"), prints and issues a receipt, and terminates the product exchange process.

[0108] Figure 6(C) shows a scenario in which a customer (Customer K) has purchased one unit each of products "AAA", "BBB", and "CCC" in a completed transaction, and has requested to exchange product "CCC" for another product "FFF". The price of product "CCC" ("538 yen") equals the price of product "FFF" ("538 yen") (see Figure 3).

[0109] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "FFF" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 6(C).

[0110] (Customer payment screen in Figure 6(C)) The display content in the original trading area 201 is the same as when the exchange item is the item "DDD" (Figures 5(B) and 5(D)).

[0111] In the resale area 202, in addition to the display field for the exchanged items (symbol c in the diagram), there are display fields for "Total," "Temporary Deposit," "Shortfall," "Deposit (Received)," "Change," and "Total Refund."

[0112] The information for the replacement item, "FFF," is displayed in the item display section. The "Total" column displays the price of the exchange item, "FFF," which is "538 yen." The "Temporary Deposit" column displays "538 yen," which is the "Refund Amount (Refund Amount from Original Transaction)" for the original transaction area 201. In the "Shortfall" column, "0 yen" is displayed, which is the result of subtracting the "Temporary Deposit" of "538 yen" from the "Total" of "538 yen". The "Deposits" column displays "0 (yen)". The "Change" field displays "0 (yen)". More details will follow. The "Total Refund" column displays "538 yen". Further details will be provided later. The "Original Transaction Refund Amount + Deposit" column displays "538 yen," which is the "Original Transaction Refund Amount" from original transaction area 201, plus "0 yen," which is the "Deposit (Deposit)" from resale area 202.

[0113] The sum of "Temporary Deposit (Refund Amount from Original Transaction)" and "Deposit (Received)" (the amount displayed in the "Refund Amount from Original Transaction + Received" column) is greater than or equal to the "Total (Total Resale Amount)," so the "End" button is displayed as operable. When customer K operates the "End" button, the registration settlement device 10 prints and issues a receipt and terminates the product exchange process.

[0114] (Display in the "Change" field on the cashier's payment screen) As mentioned above, "change" refers to the amount of change (payment amount) given to customer K in the correction (product exchange process). The "change" on the cashier's settlement screen is calculated using the amount on the cashier's settlement screen, for example, by adding up "overpayment / underpayment" and "cash received (deposit)".

[0115] For example, in the scenario shown in Figure 5(C), the "surplus / shortage" is "-142 yen" and the "deposit" is "200 yen". Therefore, in the scenario shown in Figure 5(C), the "change" is the sum of the "surplus / shortage" of "-142 yen" and the "deposit" of "200 yen", which is "58 yen". Thus, in Figure 5(C), "58 yen" is displayed in the "change" column.

[0116] In the scenario shown in Figure 5(A), the "surplus / deficit" is "-142 (yen)," and the "amount received (deposit)" is left blank, but in reality it is "0 (yen)." Therefore, in the scenario shown in Figure 5(A), the "change" will not be a positive amount (it will be "-142 (yen)"). For this reason (to avoid confusion, etc.), the "change" column is left blank in the scenario shown in Figure 5(A).

[0117] (Display of the "Change" and "Total Refund" fields on the customer payment screen) As mentioned above, "change" is the amount of change (payment amount) given to customer K in the correction (product exchange process). The "change" on the customer settlement screen is calculated using the amount on the customer settlement screen, for example, by subtracting the "shortfall" from the "deposit (deposit)". Also, as mentioned above, the "total refund" is the sum of the "original transaction refund amount (refund amount)" and the "change".

[0118] For example, in the scenario shown in Figure 5(D), the "deposit (received)" is "200 (yen)" and the "shortfall" is "142 (yen)". Therefore, in the scenario shown in Figure 5(D), the "change" is "58 (yen)", which is the "deposit (received)" of "200 (yen)" minus the "shortfall" of "142 (yen)". Thus, in Figure 5(D), "58 (yen)" is displayed in the "change" column. Also, in the scenario shown in Figure 5(D), the "refund amount for the original transaction" is "538 (yen)". Therefore, in the scenario shown in Figure 5(D), the "total refund" is "596 (yen)", which is the sum of the "refund amount for the original transaction" of "538 (yen)" and the "change" of "58 (yen)". Therefore, in Figure 5(D), "596 (yen)" is displayed in the "Total Refund" column.

[0119] In the scenario shown in Figure 5(B), the "deposit (received)" is "0 (yen)" and the "shortfall" is "142 (yen)". Therefore, in the scenario shown in Figure 5(B), the "change" will not be a positive amount (it will be "-142 (yen)"). For this reason (to avoid confusion, etc.), the "change" column is left blank in the scenario shown in Figure 5(B). Similarly, for the same reason, the "total refund" column is left blank in the scenario shown in Figure 5(B). In other words, in the scenario shown in Figure 5(B), the "total refund" is calculated as the sum of the "original transaction refund amount (refund amount)" of "538 (yen)" and the "change" of "-142 (yen)", which is "396 (yen)". However, since the "change" column is left blank instead of displaying "-142 (yen)", the "total refund" column is also left blank instead of displaying "396 (yen)".

[0120] In the scenario shown in Figure 6(A), the "deposit (received)" is "0 (yen)" and the "shortfall" is "-98 (yen)". Therefore, in the scenario shown in Figure 6(A), the "change" is "98 (yen)", which is the "deposit (received)" of "0 (yen)" minus the "shortfall" of "-98 (yen)". Thus, in Figure 6(A), "98 (yen)" is displayed in the "change" column. Also, in the scenario shown in Figure 6(A), the "original transaction refund amount (refund amount)" is "538 (yen)". Therefore, in the scenario shown in Figure 6(A), the "total refund" is "636 (yen)", which is the sum of the "original transaction refund amount (refund amount)" of "538 (yen)" and the "change" of "98 (yen)". Thus, in Figure 6(A), "636 (yen)" is displayed in the "total refund" column.

[0121] In the scenario shown in Figure 6(B), the "deposit (received)" is "2 (yen)" and the "shortfall" is "-98 (yen)". Therefore, in the scenario shown in Figure 6(B), the "change" is "100 (yen)", which is the "deposit (received)" of "2 (yen)" minus the "shortfall" of "-98 (yen)". Thus, in Figure 6(B), "100 (yen)" is displayed in the "change" column. Also, in the scenario shown in Figure 6(B), the "original transaction refund amount (refund amount)" is "538 (yen)". Therefore, in the scenario shown in Figure 6(B), the "total refund" is "638 (yen)", which is the sum of the "original transaction refund amount (refund amount)" of "538 (yen)" and the "change" of "100 (yen)". Thus, in Figure 6(B), "638 (yen)" is displayed in the "total refund" column.

[0122] In the scenario shown in Figure 6(C), the "deposit (received)" is "0 (yen)" and the "shortfall" is "0 (yen)". Therefore, in the scenario shown in Figure 6(C), the "change" is "0 (yen)", which is obtained by subtracting the "shortfall" (0 (yen)) from the "deposit (received)" (0 (yen)). Thus, in Figure 6(C), "0 (yen)" is displayed in the "change" column. Also, in the scenario shown in Figure 6(C), the "original transaction refund amount (refund amount)" is "538 (yen)". Therefore, in the scenario shown in Figure 6(C), the "total refund" is "538 (yen)", which is the sum of the "original transaction refund amount (refund amount)" (538 (yen)) and the "change" (0 (yen)). Thus, in Figure 6(C), "538 (yen)" is displayed in the "total refund" column.

[0123] [Second display example] Figure 7 shows a second example of the display on the customer-side display unit 103. When a store clerk selects item "CCC" as the item to be returned and presses the complete button (step 6), and scans item "DDD" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 7(A). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 7(A) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 5(B).

[0124] (Customer payment screen in Figure 7(A)) The customer settlement screen in Figure 7(A) includes fields for displaying "Payment Amount," "Amount Received," "Shortfall," "Refund Amount for Original Transaction," and "Total Refund."

[0125] The "Payment Amount" is the total amount of the exchanged items (total resale value). In Figure 7(A), the "Payment Amount" column shows the amount of the exchanged item "DDD" as "680 (yen)". The "Amount Received" is the sum of the total amount of returned goods (the refund amount in the original transaction) and the amount received from customer K (the amount paid by customer K in this correction). The scene in Figure 7(A) is before the deposit is received from customer K, so in Figure 7(A), the amount of the returned item "CCC," "538 yen," is displayed in the "Amount Received" field. The "Amount Received" field on the customer settlement screen in Figure 7(A) (and similarly on the customer settlement screens in Figures 7(B) to 7(E)) corresponds to the "Refund Amount from Original Transaction + Deposit" field on the customer settlement screens in Figures 5(B), 5(D), and 6(A) to 6(C). "Shortfall" is the amount obtained by subtracting "Amount Received" from "Amount to be Paid". In Figure 7(A), the "Shortfall" column shows "142 yen", which is the result of subtracting "538 yen" from "680 yen". The "Refund Amount from Original Transaction" is the refund amount from the original transaction. In Figure 7(A), the "Refund Amount from Original Transaction" column shows the amount of "538 yen" for the returned item "CCC". The "Total Refund" is the sum of the "Refund Amount from the Original Transaction" and the "Change." If there is no shortfall, the "Total Refund" column will display the sum of the "Refund Amount from the Original Transaction" and the "Change." If there is a shortfall, the "Total Refund" column will be left blank. In Figure 7(A), there is a shortfall of "142 yen," so the "Total Refund" column is left blank.

[0126] In the scenario shown in Figure 7(A), when customer K deposits 200 yen, the registration and settlement device 10 displays the customer settlement screen shown in Figure 7(B) on the customer-side display unit 103. In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 7(B) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 5(D).

[0127] (Customer payment screen in Figure 7(B)) The customer settlement screen in Figure 7(B) includes fields for displaying "Payment Amount," "Amount Received," "Change," "Refund Amount for Original Transaction," and "Total Refund."

[0128] In Figure 7(A), the "Amount Received" column displayed the sum of the amount for the returned item "CCC" ("538 yen") and the deposit (received amount) ("0 yen"), totaling "538 yen." However, in Figure 7(B), the "Amount Received" column displays the sum of the amount for the returned item "CCC" ("538 yen") and the deposit (received amount) ("200 yen"), totaling "738 yen." "Change" is the amount obtained by subtracting the "payment amount" from the "deposit amount". In Figure 7(B), the "change" column displays "58 yen", which is obtained by subtracting "680 yen" from "738 yen". In other words, in Figure 7(A), since "deposit amount" < "payment amount" (there is a shortage), a "shortfall" column is provided and "142 yen" is displayed, which is obtained by subtracting the "deposit amount" of "538 yen" from the "payment amount" of "680 yen". However, in Figure 7(B), since "deposit amount" ≥ "payment amount" (there is no shortage), a "change" column is provided and "58 yen" is displayed, which is obtained by subtracting the "payment amount" of "680 yen" from the "deposit amount" of "738 yen". In Figure 7(A), the "Total Refund" column was left blank because there was a shortage. However, in Figure 7(B), since there is no shortage, the "Total Refund" column displays "596 yen," which is the sum of the "Refund Amount for the Original Transaction" of "538 yen" and the "Change" of "58 yen."

[0129] Since the "Amount Received (the sum of the total amount of returned goods and the amount received from customer K)" is equal to or greater than the "Amount to Pay (total amount of resales)," meaning there is no shortfall, the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("58 yen"), prints and issues a receipt, and ends the product exchange process.

[0130] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "EEE" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 7(C). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 7(C) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(A).

[0131] (Customer payment screen in Figure 7(C)) The "Payment Amount" column displays the price of the replacement item, "EEE," which is "440 yen." The "Amount Received" is the sum of the total amount of returned goods (the refund amount in the original transaction) and the deposit received from customer K. However, the scene in Figure 7(C) is before the deposit is received from customer K, so in Figure 7(C), the amount of the returned item "CCC," which is "538 yen," is displayed in the "Amount Received" column. "Change" is the amount obtained by subtracting the "payment amount" from the "deposit amount," but in Figure 7(C), "98 yen" is displayed in the "change" column, which is obtained by subtracting "440 yen" from "538 yen." The "Refund Amount for Original Transaction" column displays the price of the returned item, "CCC," which is "538 yen." Since there are no shortfalls, the "Total Refund" column displays "636 yen," which is the sum of the "Refund Amount from Original Transaction" (538 yen) and the "Change" (98 yen).

[0132] Since the "Amount Received (the sum of the total amount of returned goods and the amount received from customer K)" is equal to or greater than the "Amount to be Paid (total amount of resale)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("98 yen"), prints and issues a receipt, and ends the product exchange process.

[0133] In the scenario shown in Figure 7(C), when customer K deposits 2 yen, the registration and settlement device 10 displays the customer settlement screen shown in Figure 7(D) on the customer-side display unit 103. In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 7(D) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(B).

[0134] (Customer payment screen in Figure 7(D)) In Figure 7(C), the "Amount Received" column displayed the sum of the amount for the returned item "CCC" ("538 yen") and the deposit (payment) ("0 yen"), totaling "538 yen." However, in Figure 7(D), the "Amount Received" column displays the sum of the amount for the returned item "CCC" ("538 yen") and the deposit (payment) ("2 yen"), totaling "540 yen." Since there are no shortfalls, the "Total Refund" column displays "638 yen," which is the sum of the "Refund Amount from Original Transaction" (538 yen) and the "Change" (100 yen).

[0135] Since the "Amount Received (the sum of the total amount of returned goods and the amount received from customer K)" is equal to or greater than the "Amount to be Paid (total amount of resale)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("100 yen"), prints and issues a receipt, and ends the product exchange process.

[0136] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "FFF" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 7(E). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 7(E) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(C).

[0137] (Customer payment screen in Figure 7(E)) The "Payment Amount" column displays the price of the replacement item, "FFF," which is "538 yen." The "Amount Received" is the sum of the total amount of returned goods (the refund amount in the original transaction) and the deposit received from customer K. However, the scene in Figure 7(E) is before the deposit is received from customer K, so in Figure 7(E), the amount of the returned item "CCC," which is "538 yen," is displayed in the "Amount Received" column. "Change" is the amount obtained by subtracting the "payment amount" from the "deposit amount," but in Figure 7(E), "0 yen" is displayed in the "change" column, which is "538 yen" minus "538 yen." The "Refund Amount for Original Transaction" column displays the price of the returned item, "CCC," which is "538 yen." Since there are no shortfalls, the "Total Refund" column displays "538 yen," which is the sum of the "Refund Amount from Original Transaction" (538 yen) and the "Change" (0 yen). It is displayed.

[0138] Since the "Amount Received (the sum of the total amount of returned goods and the amount received from customer K)" is equal to or greater than the "Amount to be Paid (total amount of resale)", the "End" button is displayed as operable. When customer K operates the "End" button, the registration settlement device 10 prints and issues a receipt and terminates the product exchange process.

[0139] [Third example of display] Figure 8 shows a third example of the display on the customer-side display unit 103. When a store clerk selects item "CCC" as the item to be returned and presses the complete button (step 6), and scans item "DDD" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 8(A). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 8(A) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 5(B) or the customer payment screen shown in Figure 7(A).

[0140] (Customer payment screen in Figure 8(A)) The customer settlement screen in Figure 8(A) includes fields for displaying "Refunded Item Amount (Returned Item Deposit Amount)", "Additional Deposit Amount", "Payment Amount", "Deposit Amount", "Shortfall", and "Total Refund".

[0141] The "Refunded Item Amount (Return Deposit Amount)" is the refund amount from the original transaction. In Figure 8(A), the "Refund Amount from Original Transaction" column shows the amount of the returned item, "CCC," which is "538 yen." The "Additional Deposit Amount" is the amount deposited by customer K in the correction (the product exchange process) (the amount paid by customer K in the correction). The scene in Figure 8(A) is before the deposit is received from customer K, so in Figure 8(A), "0 (yen)" is displayed in the "Additional Deposit Amount" column. The "Payment Amount" is the total amount of the exchanged items (total resale value). In Figure 8(A), the "Payment Amount" column shows the amount of the exchanged item "DDD" as "680 (yen)". The "Amount Held" is the sum of the "Refunded Item Amount (Returned Item Amount)" and the "Additional Amount Held." In Figure 8(A), the "Amount Held" column displays "538 yen," which is the sum of the "Refunded Item Amount (Returned Item Amount)" of "538 yen" and the "Additional Amount Held" of "0 yen." The "Amount Held" column on the customer settlement screen in Figure 8(A) (and similarly on the customer settlement screens in Figures 8(B) to 8(E)) corresponds to the "Refunded Amount from Original Transaction + Deposit" column on the customer settlement screens in Figures 5(B), 5(D), and 6(A) to 6(C). The arrow (symbol d) indicates that the "Amount Held" is the sum of the "Refunded Item Amount (Returned Item Amount)" and the "Additional Amount Held." "Shortfall" is the amount obtained by subtracting "Amount Received" from "Amount to be Paid". In Figure 8(A), the "Shortfall" column shows "142 yen", which is the result of subtracting "538 yen" from "680 yen". The "Total Refund" is the sum of the "Refunded Item Amount (Returned Item Amount)" and the "Change". If there is no shortfall, the "Total Refund" column will display the sum of the "Refunded Item Amount (Returned Item Amount)" and the "Change". If there is a shortfall, the "Total Refund" column will be left blank. In Figure 8(A), there is a shortfall of "142 yen", so the "Total Refund" column is left blank.

[0142] In the scenario shown in Figure 8(A), when customer K deposits 200 yen, the registration and settlement device 10 displays the customer settlement screen shown in Figure 8(B) on the customer-side display unit 103. In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 8(B) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 5(D) or the customer payment screen shown in Figure 7(B).

[0143] (Customer payment screen in Figure 8(B)) The customer settlement screen in Figure 8(B) includes display fields for "Refunded Item Amount (Returned Item Deposit Amount)", "Additional Deposit Amount", "Payment Amount", "Deposit Amount", "Change", and "Total Refund".

[0144] In Figure 8(A), the "Additional Deposit Amount" column displayed "0 (yen)," but in Figure 8(B), the "Additional Deposit Amount" column displays "200 (yen)." In Figure 8(A), the "Amount Received" column displayed "538 yen," which is the sum of "Refunded Item Amount (Returned Item Received)" of "538 yen" and "Additional Item Received" of "0 yen." However, in Figure 8(B), the "Amount Received" column displays "738 yen," which is the sum of "Refunded Item Amount (Returned Item Received)" of "538 yen" and "Additional Item Received" of "200 yen." In Figure 8(A), since "Amount Received" < "Amount Paid" (there is a shortfall), a "Shortfall" column is provided, and "142 yen" is displayed, which is the "Amount Received" of "538 yen" subtracted from the "Amount Paid" of "680 yen". However, in Figure 8(B), since "Amount Received" ≥ "Amount Paid" (there is no shortfall), a "Change" column is provided, and "58 yen" is displayed, which is the "Amount Paid" of "738 yen" subtracted from the "Amount Paid" of "680 yen". In Figure 8(A), the "Total Refund" column was left blank because there was a shortage. However, in Figure 8(B), since there is no shortage, "596 yen" is displayed, which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Change" of "58 yen".

[0145] Since the "Amount Received (the sum of the "Refunded Item Amount (Returned Item Received Amount)" and the "Additional Item Received Amount)" is equal to or greater than the "Payment Amount (Total Resale Amount)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("58 yen"), prints and issues a receipt, and terminates the product exchange process.

[0146] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "EEE" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 7(C). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 8(C) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(A) or the customer payment screen shown in Figure 7(C).

[0147] (Customer payment screen in Figure 8(C)) The "Refunded Item Amount (Return Deposit Amount)" column displays the amount of the returned item, "CCC," which is "538 yen." The "Additional Deposit Amount" is the amount deposited by customer K in the correction (the product exchange process) (the amount deposited by customer K in the correction). However, since the scene in Figure 8(C) is before the deposit is received from customer K, "0 (yen)" is displayed in the "Additional Deposit Amount" column in Figure 8(C). The "Payment Amount" column displays the price of the replacement item, "EEE," which is "440 yen." The "Amount Received" column displays "538 yen," which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Additional Deposit Amount" of "0 yen." "Change" is the amount obtained by subtracting the "payment amount" from the "deposit amount," but in Figure 8(C), "98 yen" is displayed in the "change" column, which is obtained by subtracting "440 yen" from "538 yen." Since there are no shortages, the "Total Refund" column displays "636 yen," which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Change" of "98 yen."

[0148] Since the "Amount Received (the sum of the "Refunded Item Amount (Returned Item Received Amount)" and the "Additional Item Received Amount)" is equal to or greater than the "Payment Amount (Total Resale Amount)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("98 yen"), prints and issues a receipt, and terminates the product exchange process.

[0149] In the scenario shown in Figure 8(C), when customer K deposits 2 yen, the registration and settlement device 10 displays the customer settlement screen shown in Figure 8(D) on the customer-side display unit 103. In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 8(D) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(B) or the customer payment screen shown in Figure 7(D).

[0150] (Customer payment screen in Figure 8(D)) In Figure 8(C), "0 (yen)" was displayed in the "Additional Deposit Amount" column, but in Figure 8(D), "2 (yen)" is displayed in the "Additional Deposit Amount" column. In Figure 8(C), the "Amount Received" column displayed "538 yen," but in Figure 8(D), the "Amount Received" column displays "540 yen." In Figure 8(C), "98 yen" is displayed in the "change" column, but in Figure 8(D), "100 yen" is displayed in the "change" column. Since there are no shortages, the "Total Refund" column displays "638 yen," which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Change" of "100 yen."

[0151] Since the "Amount Received (the sum of the "Refunded Item Amount (Returned Item Received Amount)" and the "Additional Item Received Amount)" is equal to or greater than the "Payment Amount (Total Resale Amount)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 dispenses the change ("100 yen"), prints and issues a receipt, and terminates the product exchange process.

[0152] When a store clerk selects product "CCC" as the item to be returned and presses the complete button (step 6), and scans product "FFF" as the item to be exchanged and presses the complete button (step 7), the registration and settlement device 10 displays a customer settlement screen on the customer-side display unit 103 as shown in Figure 8(E). In other words, the registration and payment device 10 may display the customer payment screen shown in Figure 8(E) on the customer-side display unit 103 instead of the customer payment screen shown in Figure 6(C) or the customer payment screen shown in Figure 7(E).

[0153] (Customer payment screen in Figure 8(E)) The "Refunded Item Amount (Return Deposit Amount)" column displays the amount of the returned item, "CCC," which is "538 yen." The "Additional Deposit Amount" is the amount deposited by customer K in the correction (the product exchange process) (the amount paid by customer K in the correction). However, since the scene in Figure 8(E) is before the deposit is received from customer K, "0 (yen)" is displayed in the "Additional Deposit Amount" column in Figure 8(E). The "Payment Amount" column displays the price of the replacement item, "FFF," which is "538 yen." The "Amount Received" column displays "538 yen," which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Additional Deposit Amount" of "0 yen." "Change" is the amount obtained by subtracting the "payment amount" from the "deposit amount," but in Figure 8(E), "0 yen" is displayed in the "change" column, which is "538 yen" minus "538 yen." Since there are no shortages, the "Total Refund" column displays "538 yen," which is the sum of "Refunded Item Amount (Return Deposit Amount)" of "538 yen" and "Change" of "0 yen."

[0154] Since the "Amount Received (the sum of the "Refunded Item Amount (Returned Item Received Amount)" and the "Additional Item Received Amount)" is equal to or greater than the "Payment Amount (Total Resale Amount)" (i.e., there is no shortage), the "Finish" button is displayed as operable. When customer K operates the "Finish" button, the registration settlement device 10 prints and issues a receipt and terminates the product exchange process.

[0155] (Other devices) The above describes an example in which the registration and settlement device 10 performs correction processing (return processing, product exchange processing), but other devices may perform the correction processing instead of or in addition to the registration and settlement device 10.

[0156] For example, the registration and settlement device 30 may perform a correction process. In the correction process, the registration and settlement device 30 displays a customer settlement screen on the customer-side display unit, such as the first to third display examples. Since the registration and settlement device 30 is a device that performs registration and settlement processes based on the store clerk's operation, when making a deposit, the store clerk puts the money received from the customer into the cash settlement unit.

[0157] The registration and payment device 50 may perform a correction process. For example, the registration and payment device 50 may perform a correction process when the customer is in face-to-face semi-self-service mode. In the correction process, the registration and payment device 50 displays a customer payment screen on the customer-side display unit, such as the first to third display examples.

[0158] The devices constituting the semi-self-service system (registration device 20, settlement device 21) may perform correction processing. In other words, in the semi-self-service system, for example, a store employee may, at the registration device, identify the original transaction, specify the returned item, register the replacement item, and then specify a settlement device 21 to perform the settlement processing. The customer may then make the necessary payment at the designated settlement device 21. In other words, the registration device 20 transmits registration information (information on the original transaction, information on the returned item, information on the replacement item) based on the store employee's operation to the settlement device 21 designated by the store employee (for example, transmitted to the settlement device 21 via the store controller 80, or transmitted to the settlement device 21 without going through the store controller 80). The settlement device 21 receives the registration information transmitted from the registration device 20 and displays a customer settlement screen, such as the first to third display examples, on the display unit (customer-side display unit).

[0159] Furthermore, if there is a shortage of funds (for example, when exchanging product "CCC" for product "DDD"), the registration device 20 will send registration information (information on the original transaction, information on the returned product, and information on the exchanged product) to the settlement device 21. However, if there is no shortage of funds (for example, when exchanging product "CCC" for product "EEE" or product "CCC" for product "FFF"), the registration device 20 does not need to send registration information to the settlement device 21 (i.e., the registration device 20 may complete the correction process on its own).

[0160] (Prevention of fraud) In registering exchange items (registration related to resale), it is permissible to restrict (regulate) processes that result in a total resale amount of 0 yen. The following examples, Case 1 and Case 2, will be used for explanation. (Case 1) This is a case where product "GGG" is designated as the returned item and product "HHH" is registered as the replacement item. The price of product "HHH" may be greater than the price of product "GGG", the price of product "HHH" may be less than the price of product "GGG", or the price of product "HHH" may be equal to the price of product "GGG". The same applies to Case 2. (Case 2) This is a case where product "GGG" is designated as the returned item, and product "HHH" and product "III" are registered as replacement items. The price of product "III" may be greater than the price of product "GGG", the price of product "III" may be less than the price of product "GGG", or the price of product "III" may be equal to the price of product "GGG".

[0161] As a restriction, the operation to cancel an exchange item may be prohibited. In other words, the registration settlement device 10 may be equipped with a restricting means (restricting means) to restrict the cancellation of an item registered as an exchange item. For example, in Case 1, the operation to cancel item "HHH" may be prohibited.

[0162] This prevents fraudulent activities by store employees, such as canceling an exchange and fraudulently obtaining the amount equivalent to the exchange (resale price). In other words, if an exchange is canceled, a receipt printed for the exchange is not issued, which could potentially lead to the aforementioned fraudulent activity. However, prohibiting the cancellation of exchanges can prevent this.

[0163] Furthermore, the operator (store clerk) may be informed that canceling an exchange is prohibited. For example, a pop-up message such as "Cancellation of an exchange is prohibited" may be displayed, or instead of a pop-up message, or in addition to it, an audio message such as "Cancellation of an exchange is prohibited" may be output.

[0164] Furthermore, if an operation to cancel an exchange item is performed, the refund amount for the original transaction may be paid. For example, in Case 1, if an operation to cancel item "HHH" is performed, it may be treated as a simple return of item "GGG". This prevents the aforementioned fraudulent activity, as the exchange item (resale) itself ceases to exist.

[0165] If even one exchange item remains uncancelled, a receipt will be issued listing the exchange item. This significantly reduces the likelihood of the aforementioned fraudulent activity. Therefore, to ensure convenience (freedom of operation), if multiple items are registered as exchange items, it may be possible to prohibit the operation of canceling all registered exchange items, while allowing (permitting) the operation of canceling some of the registered exchange items. For example, in Case 2, it may be possible to prohibit the operation of canceling item "III" after canceling item "HHH", or canceling item "HHH" after canceling item "III", while allowing the operation of canceling item "III" while item "HHH" has not been canceled, or canceling item "HHH" while item "III" has not been canceled.

[0166] If multiple items are registered as exchange items, instead of the above, you may prohibit the operation of canceling some of the items registered as exchange items. In other words, in Case 2, you may prohibit the operation of canceling item "III" without knowing whether item "HHH" has been canceled or not, and you may prohibit the operation of canceling item "HHH" regardless of whether item "III" has been canceled or not.

[0167] Instead of prohibiting the operation of canceling the exchange item itself, you may also prohibit the operation of the "Complete" button after canceling the exchange item (the "Complete" button in step 7, which corresponds to the subtotal operation in the registration process).

[0168] For example, in Case 1, the operation to cancel product "HHH" may not be prohibited (the operation to cancel product "HHH" may be permitted), but the operation of the complete button after canceling product "HHH" may be prohibited. In Case 2, the operation to cancel both product "HHH" and product "III" may not be prohibited (the operation to cancel both product "HHH" and product "III" may be permitted), but the operation of the complete button after canceling both product "HHH" and product "III" may be prohibited. Also, in Case 2, the operation to cancel either product "HHH" or product "III" may not be prohibited (the operation to cancel either product "HHH" or product "III" may be permitted), but the operation of the complete button after canceling either product "HHH" or product "III" may be prohibited.

[0169] As a restriction, the operation to correct (change) the amount of an item registered as an exchange item to 0 yen may be prohibited. For example, in Case 1 (following the scene in Case 1), the operation to correct the amount of item "HHH" to 0 yen may be prohibited. In other words, the registration settlement device 10 may be equipped with a restricting means (restricting means) to restrict (regulate) the change of the amount of an item registered as an exchange item to 0 yen.

[0170] This prevents fraudulent activities by store employees, such as correcting the price of an exchange item to 0 yen and fraudulently obtaining the amount for the exchange item (the amount to be resold). For example, there is a risk that an employee might pretend to the customer that the transaction is complete, and then, after the customer leaves, correct the price of the exchange item to 0 yen and fraudulently obtain the amount for the exchange item. However, this can be prevented by prohibiting the operation of correcting the price of an exchange item to 0 yen.

[0171] Furthermore, the operator (store clerk) may be informed that correcting the price of the exchange item to 0 yen is prohibited. For example, a pop-up message such as "Correcting the price of the exchange item to 0 yen is prohibited" may be displayed, or instead of or in addition to a pop-up message, an audio message such as "Correcting the price of the exchange item to 0 yen is prohibited" may be output.

[0172] Furthermore, if the amount of the exchanged item is corrected to 0 yen, the refund amount of the original transaction may be paid. For example, in Case 1, if the amount of item "HHH" is corrected to 0 yen, it may be treated as a simple return of item "GGG". This prevents the aforementioned fraudulent activity, as the exchanged item (resale) itself ceases to exist.

[0173] If multiple items are registered as exchange items, the operation of correcting the price of all items registered as exchange items to 0 yen may be prohibited, while the operation of correcting the price of some of the items registered as exchange items to 0 yen may be permitted. For example, in Case 2 (following the scene in Case 2), the operation of correcting the price of item "III" to 0 yen after correcting the price of item "HHH" to 0 yen (while the price of item "HHH" is 0 yen) or the operation of correcting the price of item "HHH" to 0 yen after correcting the price of item "III" to 0 yen (while the price of item "III" is 0 yen) may be prohibited, while the operation of correcting the price of item "III" to 0 yen while the price of item "HHH" is not 0 yen or the operation of correcting the price of item "HHH" to 0 yen while the price of item "III" is not 0 yen may be permitted.

[0174] If multiple items are registered as exchange items, instead of the above, the operation to correct the amount of some of the items registered as exchange items to 0 yen may be prohibited. For example, in Case 2, the operation to correct the amount of item "III" to 0 yen may be prohibited regardless of whether the amount of item "HHH" is 0 yen or not, and the operation to correct the amount of item "HHH" to 0 yen may be prohibited regardless of whether the amount of item "III" is 0 yen or not.

[0175] It is not the operation of correcting the price of an item registered as an exchange item to 0 yen that is prohibited, but rather the operation of the "Complete" button after correcting the price of the item registered as an exchange item to 0 yen (while the price of the item is 0 yen) may be prohibited.

[0176] For example, in Case 1, the operation to correct the amount of product "HHH" to 0 yen may not be prohibited (the operation to correct the amount of product "HHH" to 0 yen may be permitted), but the operation of the "Complete" button after correcting the amount of product "HHH" to 0 yen may be prohibited. In Case 2, the operation to correct the amounts of both product "HHH" and product "III" to 0 yen may not be prohibited (the operation to correct the amounts of both product "HHH" and product "III" to 0 yen may be permitted), but the operation of the "Complete" button after correcting the amounts of both product "HHH" and product "III" to 0 yen may be prohibited. Also, in Case 2, the operation to correct the amount of either product "HHH" or product "III" to 0 yen may not be prohibited (the operation to correct the amount of either product "HHH" or product "III" to 0 yen may be permitted), but the operation of the "Complete" button after correcting the amount of either product "HHH" or product "III" to 0 yen may be prohibited.

[0177] Corrections to amounts other than 0 yen may also be restricted. In other words, corrections to the amount of the exchange item may be restricted regardless of the amount to be corrected. For example, in Case 1, regardless of the amount to be corrected, the operation to correct the amount of item "HHH" may be prohibited, and the operation of the complete button after correcting the amount of item "HHH" may be prohibited. In Case 2, regardless of the amount to be corrected, the operation to correct the amounts of both item "HHH" and item "III" may be prohibited, and the operation of the complete button after correcting the amounts of both item "HHH" and item "III" may be prohibited. Also in Case 2, regardless of the amount to be corrected, the operation to correct the amount of either item "HHH" or item "III" may be prohibited, and the operation of the complete button after correcting the amount of either item "HHH" or item "III" may be prohibited.

[0178] In other words, you may restrict (regulate) changing the price of a registered exchange item to an amount different from the registered amount (0 yen or an amount other than 0 yen). Alternatively, you may restrict changes to an amount lower than the registered amount, while allowing changes to an amount higher than the registered amount.

[0179] (Removal of restrictions on payout amounts) Normally, withdrawals of 10,000 yen or more are restricted, but considering cases where the refund amount of the original transaction exceeds 10,000 yen, the above restriction will be lifted. Furthermore, it is possible to allow the withdrawal of 10,000 yen bills, or to allow withdrawals of 10,000 yen or more while prohibiting the withdrawal of 10,000 yen bills.

[0180] As described above, according to the embodiment, customers can easily grasp the movement of money.

[0181] (Variations, etc.) Although embodiments have been described above, the configuration of the equipment, the data configuration, the processing flow, the display and output modes, etc., can be modified as appropriate, for example, as shown in Modifications 1 to 7 below. Furthermore, Modifications 1 to 7 can be combined as appropriate.

[0182] (Modification 1) In the above embodiment, settlement (dispensing change if there is any, printing and issuing a receipt) is initiated based on the operation of the end button. However, if settlement is possible (if there is no shortage of money), settlement may be initiated without the operation of the end button. For example, when exchanging product "CCC (538 yen)" for product "FFF (538 yen)", the receipt may be printed and issued without the operation of the end button (for example, without displaying the end button). In other words, if the amounts match, the process may be terminated without the operation of the end button in order to suppress unnecessary cash movement.

[0183] Furthermore, when exchanging product "CCC (538 yen)" for product "EEE (440 yen)", the change (98 yen) may be dispensed and a receipt printed and issued even without the operation of the "end" button (for example, without displaying the "end" button). When exchanging product "CCC (538 yen)" for product "DDD (680 yen)" and a deposit of 200 yen is made, the change (58 yen) may be dispensed and a receipt printed and issued even without the operation of the "end" button (for example, after a predetermined time has elapsed since the 200 yen deposit).

[0184] (Modification 2) In the above embodiment, an example was described in which the amount of "change" is displayed before the End (Receipt) button is operated. However, the amount of "change" may be displayed after the End (Receipt) button is operated. In other words, in the first display example, the amount in the "Original Transaction Refund Amount + Deposit" field may be finalized by the operation of the End (Receipt) button, and the amount may be displayed in the "Change" field after the amount in the "Original Transaction Refund Amount + Deposit" field has been finalized (upon finalization). In the second and third display examples, the amount in the "Amount Received" field may be finalized by the operation of the End (Receipt) button, and the amount may be displayed in the "Change" field after the amount in the "Amount Received" field has been finalized (upon finalization).

[0185] (Modification 3) In the above embodiment, the product exchange process was described as a process that encompasses the return of a sold product and the registration of another product as a single transaction. However, the transaction related to the return of a sold product and the transaction related to the registration of another product may be processed together. In other words, it may be configured to be processed as a single transaction encompassing the return of a sold product and the registration of another product, or internally, even if it is two transactions (a transaction related to the return of a sold product and a transaction related to the registration of another product), it may be configured so that these two transactions are processed together (integrally). Both configurations may be called product exchange processing.

[0186] (Modification 4) In the above embodiment, an example of displaying various amounts (amount information) using numbers (numerical values) has been described, but the method of display is not limited to this. For example, the amount information may be displayed as a graph, either in place of numbers or in addition to numbers. For example, the graph may be displayed in the following manner. Before deposit: Display graphs of the original transaction refund amount and the exchange item amount. In the graph of the exchange item amount, the difference (surplus or deficit) between the original transaction refund amount and the exchange item amount may be displayed in red or blue for comparison. For example, if the original transaction refund amount > the exchange item amount, the excess (available amount) will be displayed in blue, and if the original transaction refund amount < the exchange item amount, the deficit will be displayed in red. After deposit: Once a deposit is received, a graph of the amount received (original transaction refund amount + deposit) will be displayed next to the graph of the exchange item's value. In the graph of the amount received, the difference (surplus or deficit) between the amount received and the original transaction refund amount may be displayed in red or blue for comparison. For example, if the amount received > the value of the exchange item, the excess will be displayed in blue, and if the amount received < the value of the exchange item, the deficit will be displayed in red. Customers can easily and visually (intuitively) grasp the amounts (individual amounts and differences) and the movement of amounts through the display of graphs and their changes.

[0187] (Modification 5) In the above embodiment, the explanation was omitted, but the processing may be made different depending on the settlement type of the original transaction. For example, restrictions may be placed on return processing and product exchange processing. (1) If the original transaction was settled in cash, the return or exchange process will be carried out using the same settlement method (cash) as the original transaction (return or exchange processes using a different settlement method than the original transaction are prohibited). (2) If the original transaction was paid for by credit card or electronic money, the return process will be carried out using the same payment method (credit card, electronic money) as the original transaction (return processing using a different payment method than the original transaction is prohibited). For product exchange processing, the refund for the returned product will be carried out using the same payment method as the original transaction (first transaction), and then (without the refund amount for the original transaction) the product will be registered and settled, which is equivalent to a resale (second transaction). The payment method for product registration (resale) is optional (it may be the same payment method as the original transaction or a different payment method). (3) If the payment method of the original transaction was the use (consumption) of points issued by the company, the return processing and product exchange processing shall be carried out using the same payment method as the original transaction (points issued by the company) (return processing and product exchange processing using a different payment method than the original transaction is prohibited). In the case of product exchange processing, the refund of the returned product shall be carried out using the same payment method as the original transaction (first transaction), and then, although it is equivalent to a resale, the product may be registered and settled (second transaction). The payment method for product registration (resale) is optional. (4) If the original transaction was settled using points not issued by the company (such as common points), the return process will be carried out using the same payment method as the original transaction (points not issued by the company) (return processing or product exchange processing using a different payment method than the original transaction is prohibited). For product exchange processing, the refund for the returned product will be carried out using the same payment method as the original transaction (first transaction), followed by registering the product and settling the payment, which is equivalent to a resale (second transaction). The payment method for product registration (resale) is optional.

[0188] (Modification 6) Although not explained in the above embodiment, if a product that was purchased using a coupon is returned (i.e., if the returned product was purchased using a coupon), it may be processed as follows, for example, in (a) to (c) below. (a) The amount after the coupon discount (the actual purchase price) will be refunded, and a coupon equivalent to the amount discounted by the coupon (i.e., a coupon equivalent to the coupon used when purchasing the returned item) will be issued. For example, a receipt coupon for the above amount will be issued. If coupons are managed electronically on a server, etc., the status of the coupon used when purchasing the returned item may be changed (used → usable). (b) The amount to which the coupon was applied will be refunded, and points equivalent to the amount discounted by using the coupon will be awarded. (c) The amount for which the coupon was not applied (the amount if the coupon was not used; the regular price) will be refunded.

[0189] (Modification 7) Some or all of the functions (input / output, storage, processing (including judgment)) in each device (registration and settlement device 10, registration device 20, settlement device 21, registration and settlement device 30, registration and settlement device 40, registration and settlement device 50, settlement device 61, etc.) may be implemented in other devices different from the device described as the main entity of the function.

[0190] For example, a part of the configuration described for a single device (e.g., the registration and settlement device 10) may be configured as a separate unit connected to that single device. In other words, for example, the registration and settlement device 10 (and other devices) may be configured as a system.

[0191] Furthermore, each device may function as a so-called thin client, specializing in input / output interfaces, etc. For example, a cloud server may execute a program to control the operation of each device, and each device may display a screen using a browsing function.

[0192] <Summary of Embodiments> [Technical field] This invention relates to a product data processing device, a program, and a product data processing system. [Background technology] A device is known that allows for the return of goods included in a settled transaction (goods that have already been sold) (see, for example, Patent Document 1). Furthermore, a method of processing the return of sold goods and the registration of other goods together is also conceivable, and this is considered to be superior in terms of efficiency and management compared to processing the return of sold goods and the registration of other goods separately. [Prior art document] [Patent] [Patent Document 1] Japanese Unexamined Patent Publication No. 2014-38424 [Overview of the prefecture] [Problems the invention aims to solve] However, when processing the return of a sold product and the registration of another product together, customers may not be able to easily grasp the details of the transaction, including the movement of money (increase, decrease, change). This invention has been made in view of these circumstances, and aims to provide a technology that allows customers to easily grasp the details of a transaction when processing the return of a sold product and the registration of another product together. [Means for solving the problem]

[0193] (1) One embodiment for solving the above-mentioned problems comprises a correction means (CPU function) for correcting settled transactions, a settlement means (cash settlement unit, non-cash settlement unit) for settling based on the corrections made by the correction means, and a customer-side display means (customer-side display unit) for displaying information to the customer, wherein the correction means is capable of returning goods and registering goods different from the goods to be returned, the settlement means is capable of deposits in addition to withdrawals, and the customer-side display means displays at least the amount of the returned goods (for example, "Refund Amount for Original Transaction" or "Refund Amount" in Figures 5(B), 5(D), and 6, "Refund Amount for Original Transaction" in Figure 7, and "Returned Goods" in Figure 8). This product data processing device (for example, the customer settlement screen in Figures 5(B), 5(D), 6, 7, and 8) is characterized by displaying the amount (return deposit amount), the sum of the amount of the returned goods and the amount received (for example, "Return Amount of Original Transaction + Received" in Figures 5(B), 5(D), and 6, and "Deposit Amount" in Figures 7 and 8), and the amount of the registered goods (for example, "Total" in the resale area 202 of Figures 5(B), 5(D), and 6, the amount in the display field (symbol c) for exchanged goods, and "Payment Amount" in Figures 7 and 8) on the same screen (for example, the customer settlement screen in Figures 5(B), 5(D), 6, 7, and 8). According to the configuration in (1), customers can easily grasp the movement of money.

[0194] (2) The product data processing device according to (1) is characterized in that the customer-side display means displays the difference between the amount of the returned product and the amount of the registered product (for example, "shortfall" in Figures 5(B) and 5(D), "shortfall (remaining balance)" in Figures 6(A) and 6(B), "shortfall" in Figure 6(C), "shortfall" in Figure 7(A), "change" in Figures 7(C) and 7(E), "shortfall" in Figure 8(A), "change" in Figures 8(C) and 8(E)) on the same screen (for example, customer settlement screen in Figures 5(B), 5(D), 6, 7(A), 7(C), 7(E), 8(A), 8(C), and 8(E)). According to the configuration in (2), customers can easily grasp the difference in price.

[0195] (3) The product data processing device according to (1) or (2), characterized in that the customer-side display means displays the amount of the returned goods as a deposit (for example, "Deposit Amount" in Figures 7(A), 7(C), 7(E), 8(A), 8(C), and 8(E)) before payment is made, and displays the total amount as a deposit (for example, "Deposit Amount" in Figures 7(B), 7(D), 8(B), and 8(D)) after payment is made. According to the configuration of (3), customers can easily understand the changes in their deposit balance in response to their deposits.

[0196] (4) The customer-side display means is a product data processing device according to (1) or (2) characterized in that it displays the product name of the returned product (for example, "CCC" in the original transaction area 201 in Figures 5(B), 5(D), and 6), the amount of the returned product (for example, "Refund Amount from Original Transaction" or "Refund Amount" in Figures 5(B), 5(D), and 6), the amount of the registered product (for example, "Total" in the resale area 202 in Figures 5(B), 5(D), and 6, and the amount in the display field (symbol c) for the exchanged product), the amount of money received (for example, "Deposit (Receipt)" in Figures 5(B), 5(D), and 6), and the amount of change (for example, "Change" in Figures 5(B), 5(D), and 6) on the same screen (for example, the customer settlement screen in Figures 5(B), 5(D), and 6). According to the configuration in (4), customers can easily check each of the above pieces of information on the same screen.

[0197] (5) The product data processing device according to (1) or (2), characterized in that it restricts changing the amount of a product registered by the correction means to an amount different from the registered amount. According to the configuration in (5), fraud by store employees can be prevented.

[0198] (6) One embodiment for solving the above-mentioned problems is a program for causing a product data processing device to function as a computer, wherein the computer functions as a correction means for correcting settled transactions, a settlement means for settling based on the corrections made by the correction means, and a customer-side display means for displaying information to the customer, wherein the correction means can return products and register products different from the products to be returned, the settlement means can make deposits in addition to withdrawals, and the customer-side display means displays at least the amount of the returned products, the sum of the amount of the returned products and the amount of the deposited products, and the amount of the registered products on the same screen. According to the configuration of (6), customers can easily grasp the movement of money.

[0199] (7) One embodiment for solving the above-mentioned problems is a product data processing system comprising: a correction unit for correcting settled transactions; a settlement unit for settling transactions based on the corrections made by the correction unit; and a customer-side display unit for displaying information to the customer, wherein the correction unit is capable of returning goods and registering goods different from the goods to be returned; the settlement unit is capable of both withdrawals and deposits; and the customer-side display unit displays at least the amount of the returned goods, the sum of the amount of the returned goods and the amount of the deposited goods, and the amount of the registered goods on the same screen. According to the configuration of (7), customers can easily grasp the movement of money.

[0200] Furthermore, the processing of each of the above-described devices (registration and settlement device 10, registration device 20, settlement device 21, registration and settlement device 30, registration and settlement device 40, registration and settlement device 50, portable registration terminal 60, settlement device 61, transaction status management device 70, headquarters server 90, etc.) may be performed by recording a program for realizing the functions of each of the above-described devices onto a computer-readable recording medium, loading the program recorded on this recording medium into a computer system, and executing it. Here, "loading the program recorded on the recording medium into a computer system and executing it" includes installing the program into the computer system. Here, "computer system" includes hardware such as the OS and peripheral devices. Also, "computer system" may include multiple computer devices connected via a network including communication lines such as the Internet, WAN, LAN, and dedicated lines. Also, "computer-readable recording medium" refers to portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and storage devices such as hard disks built into the computer system. Thus, the recording medium on which the program is stored may be a non-transient recording medium such as a CD-ROM. Furthermore, the recording medium includes internal or external recording media accessible from the distribution server for distributing the program. The program code stored on the distribution server's recording medium may be different from the program code in an executable format for the terminal device. In other words, the format in which it is stored on the distribution server is irrelevant as long as it can be downloaded from the distribution server and installed in an executable format for the terminal device. It is also acceptable for the program to be divided into multiple parts, downloaded at different times, and then combined on the terminal device, and for each of the divided programs to be distributed by a different distribution server. Moreover, "computer-readable recording medium" includes volatile memory (RAM) within computer systems that act as servers or clients when a program is transmitted over a network, which retains the program for a certain period of time. Furthermore, the program may be intended to implement only a part of the functions described above.Furthermore, the above-mentioned functions may be realized in combination with programs already recorded in the computer system, such as so-called differential files (differential programs).
