[0029] [Sales registration and payment processing] Next, a description will be given of the operation of the sales data processing device 100 according to this embodiment.

[0030] First, the POS side control unit 11 displays the sales registration screen 141 shown in Fig. 5 on the POS side display unit 14, and executes a sales registration process to accept input of the product name, quantity, and price, which are sales information, via the input unit 31 (step S1). Here, nothing is displayed on the settlement side display unit 24, and the user sees the sales registration screen 141 displayed on the POS side display unit 14 through the screen of the settlement side display unit 24. The POS side control unit 11 displays the input information in a field 142 of the sales registration screen 141 shown in Fig. 5, calculates the total price of the input products, and displays it in a field 143. Next, the POS control unit 11 transmits the calculated total amount information (payment amount information) to the settlement unit 2 via the POS communication unit 15 (step S2). After transmission, the POS control unit 11 erases the display on the POS display unit 14.

[0031] The settlement side control unit 21 receives the transmitted total amount information via the settlement side communication unit 25, and displays the settlement screen 241 shown in Fig. 6 on the settlement side display unit 24. Since the display on the POS side display unit 14 is erased at this time, the user only sees the settlement screen 241 displayed on the settlement side display unit 24. The settlement side control unit 21 displays the received total amount (payment amount) in the field 242 of the settlement screen 241 shown in Fig. 6 (step S3). Here, payment methods such as card company and lump-sum payment are preset in the Fn keys 243 of the payment screen 241 shown in Fig. 6. The payment side control unit 21 accepts the selection of the payment method from the Fn keys 243 of the payment screen 241 (step S4). Next, the settlement side control unit 21 receives the card information read from the external card reader via the settlement side external communication unit 26 (step S5).

[0032] Next, the settlement side control unit 21 randomly displays the input keys 244 for inputting the card's personal identification number (PIN code) on the settlement screen 241 as shown in Fig. 7 (step S6). The input unit 31 that accepts input is shared by the POS unit 1 and the settlement unit 2, and the POS side control unit 11 is usually set not to accept the input signal of the input unit 31 on the settlement screen 241. However, if this setting is not made, the position of the key that was entered on the POS unit 1 side can be determined. Therefore, security can be improved by randomly displaying the positions of the input keys 244 so that the entered personal identification number cannot be determined on the POS unit 1 side. The position of the input keys 244 is changed every time a settlement process is performed. Next, the settlement side control unit 21 accepts input of a PIN via the input unit 31 (step S7). When the settlement side control unit 21 accepts input of a PIN, it displays "*" in the field 245 of the settlement screen 241 shown in FIG. Next, the payment side control unit 21 generates payment information based on the total amount information, the card information received in step S5, and the PIN number accepted in step S7, and encrypts the payment information (step S8). Next, the payment side control unit 21 transmits the encrypted payment information to the POS unit 1 via the payment side communication unit 25. The POS side control unit 11 receives the payment information via the POS side communication unit 15, and transmits the payment information via the POS side external communication unit 16 to an external server or the like that performs a payment information registration process (step S9), thereby completing the sales registration and settlement process.

[0033] As described above, the sales data processing device 100 according to the above embodiment comprises a first control unit (POS side control unit 11) that executes a sales registration process, and a second control unit (payment side control unit 21) that executes a payment process related to the transaction of goods or services registered as sales by the sales registration process. When executing the sales registration process, the first control unit accepts an input operation of sales information via the touch panel (input unit 31) while a sales registration screen is displayed on either one of the first display unit (POS side display unit 14) or the second display unit (payment side display unit 24). When executing the payment process, the second control unit accepts an input operation of authentication information via the touch panel (input unit 31) while a payment screen is displayed on the other of the first display unit or the second display unit. Therefore, the sales data processing device 100 can achieve space saving while ensuring security.

[0034] (Modification) The following description will focus on the differences between this modified example and the sales data processing device 100 of the above embodiment.

[0035] In this modification, in the sales registration settlement process of the above embodiment, the POS side control unit 11 does not erase the display on the POS side display unit 14 after transmitting the total amount information (payment amount information) to the settlement unit 2. Therefore, in step S3 of the sequence diagram of the sales registration settlement process shown in FIG. 4, when the settlement side control unit 21 displays the settlement screen 241 on the settlement side display unit 24, the user can simultaneously view the sales registration screen 141 and the settlement screen 241. FIG. 8 shows an example in which the sales registration screen 141 and the settlement screen 241 are simultaneously displayed. The total amount (payment amount) is displayed in the field 143 of the sales registration screen 141 shown in FIG. 8, and the total amount is displayed in the field 242 of the settlement screen 241, so that the user can confirm whether the total amount displayed on the settlement screen 241 is correct.

[0036] As described above, in the sales data processing device 100 relating to the above-mentioned embodiment and modified example, the first display unit (POS side display unit 14), the second display unit (payment side display unit 24), and the touch panel (input unit 31) are arranged so as to overlap each other, thereby realizing space saving. Furthermore, the first display unit (POS side display unit 14) is arranged so that the display content can be seen through the second display unit (payment side display unit 24), so that space saving can be achieved by stacking the first display unit and the second display unit. In addition, the second control unit (payment side control unit 21) displays a plurality of input keys for inputting authentication information on the payment screen in a different order for each payment process. Therefore, the POS unit 1 cannot determine the input PIN. This further improves the security ensured by the above-mentioned configuration. In addition, when the payment process is executed by the second control unit (payment side control unit 21), the first control unit (POS side control unit 11) displays at least a part of the display content included in the sales registration screen on one of the display units, so that the user can check whether the total amount displayed on the payment screen 241 is correct. In addition, the first control unit (POS side control unit 11) transmits the payment amount information derived in the sales registration process via the first communication unit (POS side communication unit 15), and the second control unit (payment side control unit 21) causes the second communication unit (payment side communication unit 25) to receive the payment amount information and executes the payment process based on the payment amount information.Therefore, the parts that perform communication between the first communication unit and the second communication unit can be separated from the parts that perform communication with the outside, thereby improving security.

[0037] As described above, the present invention is not limited to the above-described embodiment, and it goes without saying that appropriate modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment and modified example, the physical button 32 of the sales data processing device 100 is shared by the POS unit 1 and the payment unit 2, but this is not limited to the above. Separate physical buttons may be provided for the POS unit 1 and the payment unit 2.

[0038] In the above embodiment and modified example, the switching from the control of the POS side control unit 11 to the control of the settlement side control unit 21 is performed by transmitting the total amount information (payment amount information) from the POS unit 1 to the settlement unit 2, but this is not limited to this. A physical button for switching from the control of the POS side control unit 11 to the control of the settlement side control unit 21 may be provided, and the switching may be performed by the physical button.

[0039] In step S2 of the sales registration settlement process in the above embodiment and modified example, the POS side control unit 11 may not transmit the total amount information (payment amount information) to the settlement unit 2 and may not erase the display on the POS side display unit 14. In this case, switching from the control of the POS side control unit 11 to the control of the settlement side control unit 21 is performed by a physical button or the like, the total amount (payment amount) displayed in the field 143 of the sales registration screen 141 is confirmed, and the total amount is manually input in the field 242 of the settlement screen 241 via the input unit 31.

[0040] In addition, in the above embodiment and modified example, the settlement side display unit 24 is provided by being stacked on the upper part of the POS side display unit 14, but the POS side display unit 14 may be provided by being stacked on the upper part of the settlement side display unit 24. In this case, the POS side display unit 14 has transparency, and when a display is performed on the display screen of the settlement side display unit 24 provided on the lower part of the POS side display unit 14, the display screen of the settlement side display unit 24 can be seen through the display screen of the POS side display unit 14.

[0041] In the above embodiment and modified example, the card information is read from an external card reader via the settlement side external communication unit 26, but this is not limited to the above. A card reader may be provided inside the sales data processing device 100 to read the card information.

[0042] In addition, in step S6 of the sales registration settlement process in the above embodiment and modified example, the input keys 244 are displayed randomly, but they do not have to be displayed randomly. In this case, in order to ensure security, it is preferable that the POS side control unit 11 does not accept the input signal of the input unit 31.

[0043] In step S9 of the sales registration settlement process in the above embodiment and modified example, the POS unit 1 transmits the settlement information to an external server or the like that performs the settlement information registration process, but this is not limited to this. The settlement side external communication unit 26 may be capable of transmitting and receiving various signals and various data by wire or wirelessly between the external device connected via a communication network (LAN, WAN, Internet, etc.), and the settlement side control unit 21 may transmit the settlement information via the settlement side external communication unit 26.
