Embodiments of the present invention will be described below with reference to the drawings.
[First embodiment]
First, a first embodiment of the present invention will be described. FIG. 1 is a block diagram showing a configuration example of an embodiment of a POS system according to the present invention. As shown in FIG. 1, in this embodiment, the POS system 1 includes a store controller 10, two product registration devices 20, and four payment devices 30. The store controller 10, the two product registration devices 20, and the four payment devices 30 are interconnected via a wired or wireless LAN (Local Area Network) 11.

Note that the configuration of the POS system 1 shown in FIG. 1 is an example, and for example, the number of product registration devices 20 and payment devices 30 can be further increased or decreased. Furthermore, the store controller 10 and the product registration device 20 and payment device 30 do not necessarily need to be connected via the LAN 11. In that case, data can be exchanged using power line communication, which utilizes electrical wiring to achieve high-speed communication. It is also possible to omit the store controller 10 by having the product registration device 20 have the functions of the store controller 10.

The store controller 10 is a computer that controls the POS system 1 and manages various information such as product master data. In addition, the store controller 10 appropriately transmits the latest product master to the product registration device 20 and each payment device 30. Here, the product master is a file that stores product information such as product identification information, product name, and selling price for each product, and is updated as appropriate. The store controller 10 also manages the settlement status of each transaction. For example, the store controller 10 stores a settlement status data table indicating the settlement status of each transaction, and notifies each product registration device 20 of the settlement status of each transaction.

The product registration device 20 performs processing for registering data on products that a customer intends to purchase. Data registration is performed, for example, by reading a barcode attached to a product. Therefore, the product registration device 20 is provided with, for example, a scanner that reads a barcode attached to a product purchased by a customer by a store clerk's operation.

Furthermore, the product registration device 20 selects the settlement device 30 that settles the transaction for which the product data is registered. The product registration device 20 then transmits data regarding the transaction to the selected payment device 30. The transaction-related data includes a transaction number that identifies the transaction, the amount of all products registered in the transaction, that is, the total amount, and the product code of the registered product. The product code is identification information that identifies the product. The customer of the transaction can operate the payment device 30 to which the data related to the transaction has been transmitted, and perform the payment process himself/herself. The settlement process is a process of paying for a product to be purchased by selectively using cash, electronic money, a credit card, etc.

Further, when the product registration device 20 transmits transaction-related data, it displays to which settlement device 30 the transaction-related data is transmitted so that the clerk or the customer can understand. For example, if the message is displayed to a store clerk, the clerk can verbally convey the information to the customer. The display method in this case is arbitrary. For example, this can be done by highlighting the sent settlement device 30 on a touch panel or the like installed toward the store clerk in the product registration device 20. Further, a guide indicating the destination payment device 30 may be displayed on a display section of the product registration device 20 facing the customer. Further, a receipt indicating the corresponding payment device 30 (for example, a numbered receipt on which the number of the payment device 30 is printed) may be issued and handed to the customer.

Further, the product registration device 20 may print out all purchase details of products purchased by the customer. In this case, before the customer operates the payment device 30 to perform payment processing, the customer can confirm the registration details using the product registration device 20 by viewing the print result.

Furthermore, the product registration device 20 can change the settlement device 30 that settles transactions. The selection of the payment device 30 is made manually by the clerk. For example, a clerk judges the status of the payment device 30 and changes the payment device 30 that settles transactions on the touch panel. With this, for example, if there is a queue of customers at the selected payment device 30, or if an automatic change machine or the like of the payment device 30 malfunctions, the payment can be made using another payment device 30. .

On the other hand, the payment device 30 is a device that is operated by the customer to perform payment processing, and includes an automatic change machine, a card reader (for example, for credit cards and point cards), and an RF (Radio Frequency) reader (for example, for electronic money). Equipped with payment devices such as

Further, when the payment device 30 receives data related to the transaction from the product registration device 20, it notifies the customer (that is, provides guidance to the customer) so that the customer knows that all they need to do is come to the payment device 30. An example of the notification is, for example, displaying character information such as a predetermined number on the entire screen of the display section of the payment device 30. This character information such as the number is information that has been separately notified to the customer by the product registration device 20 (or by the store clerk operating the product registration device 20). For example, the customer can go to the payment device 30 displaying his/her own number. Further, as another example of notification, guidance may be provided by lighting a predetermined lamp included in the payment device 30. For example, the light is lit in a specific color so that the customer goes to the checkout device 30 of the specified color. Alternatively, it may be blinking or the like. Further, as another example of notification, the membership card number may be displayed on the screen of the payment device 30. This membership card number is read by the product registration device 20, for example. The customer will go to the payment device 30 which informs him of his membership card number.

Further, the payment device 30 enters a standby state after the notification. That is, after making the notification, the settlement device 30 enters a state in which it waits for an instruction to start the settlement process corresponding to the received transaction data. As an example of canceling the standby state, for example, when a customer touches the display screen of the payment device 30 (or presses a certain button), payment processing may be automatically started. Until you touch it, nothing is displayed on the screen, or only a number is displayed as in the notification example above. Alternatively, the payment device 30 may detect whether a customer approaches using a human sensor and start the payment process. In this case as well, the screen can be left blank or displayed with a number until it is detected. The payment device 30 starts payment processing when the human sensor detects the approach of a person. Alternatively, a camera can be used instead of a human sensor. For example, cameras may be installed in the payment device 30 and the product registration device 20, and the payment process may be started only when the same person approaches by facial recognition.

Further, the flow of payment processing for the payment device 30 in a standby state can be performed as follows, for example. (1) First, select a payment method. The customer selects whether to use cash, credit card, electronic money, etc. or to use both of them according to the customer's operation. (2) Next, execute payment. Settlement is executed by inserting cash into the bill or coin input/output port of the settlement device 30, paying change, reading a card with a card reader, etc. (3) Next, a receipt is issued using the printing unit included in the payment device 30. For example, a list of purchased products, the total purchase price, the received price, the change amount, etc. are printed on the receipt. (4) Then, the payment device 30 ends the payment processing and becomes vacant.

Note that the payment method in the payment device 30 may be declared in the product registration device 20. In this case, the product registration device 20 sends the payment method information to the settlement device 30, and the settlement device 30 starts processing from the operation (2) above.

Next, with reference to FIGS. 2 and 3, a configuration example of the product registration device 20 and payment device 30 in FIG. 1 will be described. FIG. 2 is a block diagram showing the configuration of the product registration device 20. As shown in FIG.

The settlement status information is a flag indicating the settlement status of the transaction.

Next, with reference to FIG. 9, the payment status data table stored in the store controller 10 will be described. FIG. 9 is a schematic diagram showing the data structure and data example of the payment status data table stored in the store controller 10. The settlement status data table shows the settlement status of each transaction. As shown in the figure, the settlement status data table has data for each item of settlement status information and settlement device number for each transaction number. Further, the payment status table is stored separately for each product registration device 20. For example, the settlement status table shown in FIG. 9(a) shows the settlement status of a transaction registered in the product registration device 20 with the product registration device number "10", and the settlement status table shown in FIG. The settlement status of the transaction registered in the product registration device 20 with number "11" is shown. Here, the first two digits of the transaction number indicate the registered device number. The store controller 10 determines with which product registration device 20 the transaction was registered based on the first two digits of the transaction number.

Next, the operation of the POS system in this embodiment will be described with reference to FIGS. 10 to 13. FIG. 10 is a sequence diagram showing processing operations in the POS system. The process shown in this figure is performed when the registration of a product in the product registration device 20 is completed. First, the product registration device 20 transmits the transaction number of the transaction for which product registration has been completed to the settlement device 30 that settles the transaction (step S101). At this time, the product registration device 20 transmits the transaction number as well as the amount of the transaction. The settlement device 30 adds and stores a set of the received transaction number, the received amount, and settlement status information "0" in the transaction data table.

Subsequently, the product registration device 20 transmits the settlement status data of the transaction for which the product registration has been completed to the store controller 10 (step S102). The settlement status data includes the transaction number of the transaction in which the product was registered, the settlement status information "0" of the transaction, and the settlement device number of the settlement device 30 that settles the transaction. Upon receiving the payment status data, the store controller 10 adds and stores the received payment status data in the payment status data table (step S111). Next, the store controller 10 determines the product registration device 20 of the received payment status data based on the first two digits of the transaction number included in the received payment status data. Then, the store controller 10 transmits the received payment status data to product registration devices 20 other than the determined product registration device 20 (step S112). When the product registration device 20 receives payment status data from other product registration devices 20, it stores the received payment status data.

Upon receiving the transaction number from the product registration device 20, the payment device 30 transmits a product data request signal requesting product data to the product registration device 20 if the payment is not in progress (step S103). This product data request signal includes the transaction number received in step S101. Note that, if the payment is in progress, the payment device 30 transmits a product data request signal to the product registration device 20 when the payment is completed. Upon receiving the product data request signal, the product registration device 20 transmits the product data to the payment device 30 (step S104). The product data includes a product code corresponding to the transaction number received in step S103. Upon receiving the product data, the settlement device 30 transmits a settlement in progress signal to the store controller 10 to notify that the transaction is being settled (step S105). The settlement in progress signal includes the transaction number of the transaction to be settled and settlement status information "1". When the store controller 10 receives the settlement signal, it rewrites the settlement status information corresponding to the transaction number included in the received settlement signal to "1" and updates the settlement status data table (step S113). Subsequently, the settlement device 30 executes settlement processing for the transaction (step S106).

When the settlement process is completed, the settlement device 30 transmits settlement completion information to the product registration device 20 to notify that the transaction settlement has been completed (step S107). The settlement completion signal includes the transaction number of the transaction for which settlement has been completed and settlement status information "2". Upon receiving the payment completion signal, the product registration device 20 rewrites the payment status information corresponding to the transaction number included in the received payment completion signal to "2" and updates the registration data table. Subsequently, the payment device 30 transmits a payment completion signal to the store controller 10 (step S108).

Upon receiving the payment completion signal, the store controller 10 updates the payment status data table by rewriting the payment status information corresponding to the transaction number included in the received payment completion signal to "2" (step S114). Next, the store controller 10 determines the product registration device 20 of the received payment completion signal based on the first two digits of the transaction number included in the payment completion signal. Then, the store controller 10 transmits the received payment completion signal to product registration devices 20 other than the determined product registration device 20 (step S115). When the product registration device 20 receives a settlement completion signal for a transaction registered by another product registration device 20, it rewrites the settlement status information corresponding to the transaction number included in the received settlement completion signal to “2” and sends it to the other product registration device 20. The payment status data of the product registration device 20 is updated.

FIG. 11 is a flowchart showing the flow of registration processing in the product registration device 20. First, the CPU 201 registers a product (step S201). Specifically, the CPU 201 displays the registration screen shown in FIG. 5 on the display unit (for store staff) 205, and starts the scanner unit 204 to read the barcode. The store clerk uses the scanner unit 204 to read the barcode of the product. The scanner unit 204 reads the product code indicated by the barcode. The CPU 201 writes the read product code into the RAM 203 and registers the product. Further, when displaying the registration screen, the CPU 201 displays the transaction number on the payment device key 501 based on the registration data file stored in the RAM 203 and payment status data of other product registration devices 20. For example, in the case of the payment device key 501a, the CPU 201 selects the transaction number "100001" for the transaction with the latest date and time among transactions where the payment device number is "1" and the payment status information is "0" or "1". ” is displayed on the payment device key 501a.

Subsequently, the CPU 201 determines whether the settlement device key 501 on the registration screen has been pressed and the settlement device 30 that settles the transaction has been designated (step S202). If the payment device key 501 is not pressed (step S202: No), the process returns to step S201. On the other hand, if the payment device key 501 is pressed (step S202: Yes), the CPU 201 sends the transaction number of the transaction in which the product was registered in step S201 to the store controller 10 that was pressed (specified) in step S202. ) is transmitted to the payment device 30 corresponding to the payment device key 501 (step S203 (corresponding to S101 and S102 described above)). Subsequently, the CPU 201 determines whether a product data request signal has been received from the payment device 30 (step S204). If the product data request signal has not been received (step S204: No), the process returns to step S204.

On the other hand, when the CPU 201 receives the product data request signal (step S204: Yes), the CPU 201 reads the product data corresponding to the transaction number included in the received product data request signal from the registered data table, and transfers the read product data to the sender. (Step S205 (corresponding to Step 104 described above)). Then, the CPU 201 displays the transaction number of the transaction in which the product was registered in step S201 on the payment device key 501 pressed in step S202 on the registration screen displayed on the display unit (for clerks) 205 (step S206 ), the process returns to step S201.

FIG. 12 is a flowchart showing the flow of accounting processing in the settlement device 30. First, the CPU 301 receives a transaction number and the amount of the transaction number from the product registration device 20 (step S301). Subsequently, the CPU 301 determines whether or not the own device is in the process of paying the bill (step S302). If the transaction is being settled (step S302: Yes), the CPU 301 writes and stores the received transaction number and amount in the transaction data table (step S303), and returns to step S302.

On the other hand, if the CPU 301 is not in the process of payment (step S302: No), the CPU 301 transmits a product data request signal including the transaction number received in step S301 to the product registration device 20 that is the source of the transaction number (step S304 (described above). (corresponding to step S103)). Subsequently, the CPU 301 receives product data from the product registration device 20 to which the product data request signal is transmitted (step S305 (corresponding to step S104 described above)). Then, the CPU 301 executes a payment process (step S306 (corresponding to step S106 described above)). At this time, the CPU 301 transmits a settlement in progress signal to the store controller 10 (step S307 (corresponding to step S105 described above)). The settlement signal includes the transaction number of the transaction being settled and settlement status information "1". When the payment processing is completed, the CPU 301 transmits a payment completion signal to the product registration device 20 and the store controller 10 (step S308 (corresponding to steps S107 and S108 described above)), and returns to step S301.

FIG. 13 is a flowchart showing the flow of change processing in the product registration device 20. The change process shown in this figure is a process executed when the unsettled transaction display button 506 is pressed on the registration screen shown in FIG. 5 (step S401). First, the CPU 201 displays the unsettled transaction screen shown in FIG. 6 on the display unit 205 (step S402). Specifically, the CPU 201 reads the transaction number, date and time, and amount of the transaction whose settlement status information is "0" from the registered data table stored in the RAM 203, and reads the read transaction number, date and time, A list of pairs with the amount is displayed on the display section (for clerk) 205. Subsequently, the CPU 201 accepts a selection input of a transaction number in the displayed list (step S403). The clerk selects the transaction number of the transaction for which the payment device 30 is to be changed from the list displayed on the display section (for clerks) 205.

When a transaction number is selected from the list on the unsettled transaction screen, the CPU 201 displays a change screen shown in FIG. 7 on the display unit (for clerk) 205 (step S404). Specifically, the CPU 201 reads the payment device number corresponding to the selected transaction number from the registered data table stored in the RAM 203, and selects the change button 701 corresponding to the payment device number other than the read payment device number and the selected transaction. The number, a cancel button 704, an add button 705, and a cancel button 706 are displayed on the display section (for clerk) 205. Subsequently, the CPU 201 determines whether a payment device number has been selected (step S405). Specifically, the CPU 201 determines whether any change button 701 has been pressed on the change screen.

If the payment device number is selected (step S405: Yes), the CPU 201 transmits a confirmation request signal to the store controller 10 inquiring whether the payment status information of the selected transaction number is "0" (step S405: Yes). S406). The confirmation request signal includes the selected transaction number. Upon receiving the confirmation request signal, the store controller 10 reads payment status information corresponding to the transaction number included in the received confirmation request signal from the payment status data table, and returns the read payment status information.

Subsequently, upon receiving the payment status information from the store controller 10, the CPU 201 determines whether the received payment status information is "0" (step S407). If the received payment status information is "0" (step S407: Yes), the CPU 201 transmits the selected transaction number and the amount corresponding to the transaction number to the payment device 30 of the selected payment device number. (Step S408), this process ends. On the other hand, if the received payment status information is not "0" (step S407: No), the CPU 201 determines that the selected transaction number is in the process of payment and therefore cannot be used for payment with another payment device 30 (the payment device 30 cannot be changed). ) is displayed on the display section (for store clerk) 205 (step S409), and the process ends.

On the other hand, if the payment device number is not selected in step S405 (step S405: No), the CPU 201 determines whether the cancel button 704 has been pressed (step S410). When the cancel button 704 is pressed (step S410: Yes), the CPU 201 executes a cancellation process to cancel the transaction of the selected transaction number (step S411), and ends this process. Specifically, the CPU 201 transmits a cancellation signal for canceling the transaction number to the payment device 30 of the payment device number corresponding to the transaction number and the store controller 10. Further, the CPU 201 deletes the record of the transaction number from the registration data table stored in the RAM 203.

On the other hand, if the cancel button 704 has not been pressed (step S410: No), the CPU 201 determines whether the add button 705 has been pressed (step S412). When the add button 705 is pressed (step S412: Yes), the CPU 201 executes an additional process to additionally register a product to the transaction number (step S413), and ends this process. Specifically, the CPU 201 displays a registration screen on the display unit (for store staff) 205 and accepts additional registration of products.

On the other hand, if the add button 705 has not been pressed (step S412: No), the CPU 201 determines whether the cancel button 706 has been pressed (step S414). If the cancel button 706 is pressed (step S414: Yes), the CPU 201 ends this process. On the other hand, if the cancel button 706 is not pressed (step S414: No), the CPU 201 returns to step S405.

As described above, according to the present embodiment, the product registration device 20 specifies the payment device 30 and transmits transaction-related data, and the payment device performs payment based on the transmitted transaction-related data. There is no need to transfer data regarding transactions between the registration device 20 and the settlement device 30. Further, depending on the payment situation, such as whether the payment of the previous customer of the specified payment device 30 is taking a long time, the designated payment device 30 may be transferred to another payment device 30 among the plurality of payment devices 30. Since it can be changed, quick settlement is possible. In addition, in this embodiment, since the payment device 30 for payment can be changed in the product registration device 20 operated by the store clerk, the store clerk can quickly select the payment device 30 to be used for payment according to the status of each payment device 30.
