The fourth communication unit 42 can also communicate with the information processing device 50 via the LAN 60 and the WAN 70; however, the use of the LAN 60 and the WAN 70 will be omitted below.

[0021] 2. Control method of payment system and receipt system when printing electronic receipts With reference to FIG. 2, a control method for the payment system and receipt system in which the information processing device 50 determines whether or not to print an electronic receipt based on a customer's selection at the store terminal device 20 and outputs the electronic receipt will be described. The first control unit 11 of the POS terminal 10 generates payment information including the product price and total amount based on the barcode read by the reader of the first input / output unit 14. The first control unit 11 generates print data based on the payment information (S101) and sends it to the receipt printer 40 (S102). The print data includes text data such as ASCII code.

[0022] When the fourth control unit 41 of the receipt printer 40 receives the print data from the POS terminal 10, it stores it in the fourth memory unit 43 (S103). Although the receipt printer 40 is capable of printing the print data, it will not print at this time and will suspend printing. As will be described later, the receipt printer 40 will not print until a print request is received from the information processing device 50. The fourth control unit 41 sends the print data to the information processing device 50 (S104).

[0023] The fifth control unit 51 of the information processing device 50 generates image data based on the print data received from the receipt printer 40 and sends it to the store terminal 20 (S105). The image data is image data that can be displayed on an LCD display or the like of the second input / output unit 24 of the store terminal 20, to show what the print data will look like when printed on paper by the receipt printer 40. Font data, which is image data corresponding to text data, is stored in the fifth storage unit 53. The fifth control unit 51 can read out the font data corresponding to the text data of the print data from the fifth storage unit 53 and generate image data. The print data is stored in the fifth storage unit 53. As described later, the print data is used when the fifth control unit 51 generates electronic receipt information.

[0024] The second control unit 21 of the store terminal device 20 displays the image data received from the information processing device 50 via the second input / output unit 24. The second control unit 21 also displays, via the second input / output unit 24, buttons that allow the customer to select either a paper receipt or an electronic receipt, along with the image data. The customer selects and operates either the paper receipt button or the electronic receipt button. The second control unit 21 detects which button was selected via the second input / output unit 24. Here, it is assumed that the second control unit 21 detects that the electronic receipt was selected (S106). The second control unit 21 transmits first selection information, which is information indicating that the electronic receipt has been selected, to the information processing device 50 (S107).

[0025] The fifth control unit 51 of the information processing device 50 determines, based on the first selection information received from the store terminal device 20, that the form in which the payment information is to be output to the customer is an electronic receipt (S108). The fifth control unit 51 reads out the print data stored in the fifth storage unit 53, and generates electronic receipt information (S109). The electronic receipt information is stored in the fifth storage unit 53. The electronic receipt information is image data that can be displayed on the LCD display of the third input / output unit 33 of the customer terminal device 30, showing an image when the print data is printed on paper by the receipt printer 40. The fifth control unit 51 can generate electronic receipt information based on the print data, similar to the image data described above. The electronic receipt information may also be the same as the image data described above.

[0026] When a customer wishes to check payment information using an electronic receipt, the customer performs a predetermined operation on the third input / output unit 33 of the customer terminal device 30. The third control unit 31 of the customer terminal device 30 generates an electronic receipt request based on a predetermined operation on the third input / output unit 33 by the customer, and transmits the electronic receipt request to the information processing device 50 (S110). When the fifth control unit 51 of the information processing device 50 receives the electronic receipt request from the customer terminal device 30, it reads out electronic receipt information from the fifth storage unit 53 and transmits it to the customer terminal device 30 (S111). Note that the transmission of the electronic receipt information by the information processing device 50 is also referred to as outputting an electronic receipt. The third control unit 31 of the customer terminal device 30 can display the electronic receipt information received from the information processing device 50 via the third input / output unit 33.

[0027] That is, the information processing device 50 can output the payment information in the form of an electronic receipt through the customer terminal device 30 based on the customer's selection of an electronic receipt on the store terminal device 20. The customer can check the payment information from the electronic receipt output on the customer terminal device 30. Note that print data stored in the fourth memory unit 43 of the receipt printer 40 is erased starting with the oldest print data if there is not enough free space in the fourth memory unit 43 when the next print data is received. Print data stored in the fourth memory unit 43 may also be erased when the next print data is received. Print data stored in the fifth memory unit 53 of the information processing device 50 is also erased at the same time.

[0028] 3. Control method of payment system and receipt system when printing paper receipts Referring to FIG. 3, a control method for the payment system and receipt system in which the information processing device 50 determines whether a paper receipt is required based on the customer's selection at the store terminal device 20 and the receipt printer 40 outputs a paper receipt will be described. The process from when the POS terminal 10 generates print data (S201) to when the store terminal 20 receives and displays image data (S205) is the same as in the case of Fig. 2, so a description thereof will be omitted. Note that the process from (S201) to (S205) shown in Fig. 3 corresponds to the process from (S101) to (S105) shown in Fig. 2.

[0029] Here, it is assumed that the customer selects and operates the paper receipt button on the store terminal 20. The second control unit 21 of the store terminal 20 detects via the second input / output unit 24 that a paper receipt has been selected instead of an electronic receipt (S206). The second control unit 21 sends second selection information, which is information indicating that a paper receipt has been selected and which differs from the first selection information, to the information processing device 50 (S207).

[0030] The fifth control unit 51 of the information processing device 50 determines that the payment information should be output to the customer in the form of a paper receipt based on the second selection information received from the store terminal device 20 (S208). The fifth control unit 51 sends a print request to the receipt printer 40 (S209). When the fourth control unit 41 of the receipt printer 40 receives a print request from the information processing device 50, it reads the print data from the fourth memory unit 43 and prints a paper receipt using the printing unit 44 (S210). Note that the information processing device 50 causing the receipt printer 40 to print a paper receipt is also referred to as outputting a paper receipt.

[0031] That is, the information processing device 50 can output the payment information in the form of a paper receipt using the receipt printer 40 based on the customer's selection of a paper receipt at the store terminal device 20. The customer can check the payment information using the paper receipt output by the receipt printer 40. Note that print data that is temporarily stored in the fourth memory unit 43 of the receipt printer 40 is erased after a paper receipt is output. Furthermore, if there is not enough free space in the fourth memory unit 43 when the next print data is received, the oldest print data may be erased first. Furthermore, print data stored in the fourth memory unit 43 may be erased when the next print data is received. Print data stored in the fifth memory unit 53 of the information processing device 50 is also erased at the same time.

[0032] 4. Method for controlling a payment system and a receipt system when printing an electronic receipt using customer identification information With reference to FIG. 4, the output of an electronic receipt based on customer identification information will be described. The customer identification information is, for example, a membership number of the customer at the store. In the following, the customer identification information will be referred to as ID. Also, a description of the same content as in "2. Control method of the payment system and receipt system when outputting an electronic receipt" described above with reference to FIG. 2 will be omitted, and the differences will be mainly described.

[0033] The first control unit 11 of the POS terminal device 10 reads information such as an IC or two-dimensional code carried on the customer terminal device 30 or the customer's card using the reader of the first input / output unit 14, and obtains the customer's ID (S301). The first control unit 11 of the POS terminal 10 sends the acquired ID to the receipt printer 40 (S302). The fourth control unit 41 of the receipt printer 40 sends the ID received from the POS terminal 10 to the information processing device 50 (S303).

[0034] The POS terminal device 10 can register the ID of a customer who requests an electronic receipt in the fifth storage unit 53 of the information processing device 50. The fifth control unit 51 of the information processing device 50 can refer to the fifth storage unit 53 to check whether the ID received from the receipt printer 40 is registered as an ID for which an electronic receipt should be output. The fifth control unit 51 of the information processing device 50 refers to the fifth memory unit 53, and if the ID received from the receipt printer 40 is registered as an ID for outputting an electronic receipt, it determines that the form in which the payment information is to be output to the customer is an electronic receipt (S304).

[0035] Next, the process from when the POS terminal device 10 generates print data (S305) to when the information processing device 50 receives the print data (S308) is the same as in the case of Fig. 2, so the description will be omitted. Note that the process from (S305) to (S308) shown in Fig. 4 corresponds to the process from (S101) to (S104) shown in Fig. 2.

[0036] As described above, the fifth control unit 51 of the information processing device 50 has already determined that the form in which the payment information is to be output to the customer is an electronic receipt (S304). The fifth control unit 51 then generates electronic receipt information based on the print data received from the receipt printer 40 (S309). The electronic receipt information is stored in the fifth storage unit 53.

[0037] The third control unit 31 of the customer terminal device 30 generates an electronic receipt request based on a predetermined operation on the third input / output unit 33 by the customer, and transmits the electronic receipt request to the information processing device 50 (S310). When the fifth control unit 51 of the information processing device 50 receives the electronic receipt request from the customer terminal device 30, the fifth control unit 51 reads out electronic receipt information from the fifth storage unit 53 and transmits it to the customer terminal device 30 (S311).

[0038] The third control unit 31 of the customer terminal device 30 can display the electronic receipt information received from the information processing device 50 via the third input / output unit 33. That is, the information processing device 50 can output the payment information in the form of an electronic receipt using the customer terminal device 30 based on the customer ID received from the POS terminal device 10 via the receipt printer 40.

[0039] It should be noted that when the fifth control unit 51 of the information processing device 50 receives print data without receiving an ID from the receipt printer 40, it can make judgments and perform processing similar to "2. Control method of the payment system and receipt system when outputting an electronic receipt" and "3. Control method of the payment system and receipt system when outputting a paper receipt" described above with reference to Figures 2 and 3.

[0040] That is, as described above, the fifth control unit 51 determines, based on the customer's selection at the store terminal device 20, whether the output format of the payment information is to be a paper receipt or an electronic receipt. If the fifth control unit 51 determines that an electronic receipt is required, it can send electronic receipt information to the customer terminal device 30 to display it. On the other hand, if the fifth control unit 51 determines that a paper receipt is required, it can cause the receipt printer 40 to print a paper receipt.

[0041] Furthermore, even if the ID received from the receipt printer 40 is not registered as an ID for outputting an electronic receipt, the fifth control unit 51 can similarly make the determinations and perform the processing described above with reference to Figures 2 and 3, "2. Control method of the payment system and receipt system when outputting an electronic receipt," and "3. Control method of the payment system and receipt system when outputting a paper receipt."

[0042] In addition, in FIG. 4, the POS terminal device 10 transmits the print data after transmitting the ID, but the print data may be transmitted together with the ID. In this case, the POS terminal device 10 sends the print data together with the ID to the information processing device 50 via the receipt printer 40. When the fifth control unit 51 of the information processing device 50 receives the print data together with the ID, it first determines that the output format is an electronic receipt based on the ID, and then generates electronic receipt information from the print data and sends it to the customer terminal device 30.

[0043] As described above, the POS system 1 of this embodiment includes a receipt printer 40 having a fourth control unit 41, an information processing device 50 having a fifth control unit 51, a POS terminal device 10 having a first control unit 11, a store terminal device 20 having a second control unit 21, and a customer terminal device 30 having a third control unit 31.

[0044] In the POS system 1, the first control unit 11 of the POS terminal device 10 generates print data and sends it to the receipt printer 40, the fourth control unit 41 of the receipt printer 40 sends the received print data to the information processing device 50, and the fifth control unit 51 of the information processing device 50 generates image data based on the received print data and sends it to the store terminal device 20. The second control unit 21 of the store terminal device 20 displays the received image data, and transmits first selection information to the information processing device 50 when the electronic receipt is selected. The fifth control unit 51 of the information processing device 50 determines that the electronic receipt is an electronic receipt based on the received first selection information, generates electronic receipt information, and transmits the electronic receipt information upon receiving an electronic receipt request from the customer terminal device 30.

[0045] According to the above-described POS system 1, when an electronic receipt is selected by the store terminal device 20, the information processing device 50 can determine that it is an electronic receipt and transmit electronic receipt information to the customer terminal device 30.

[0046] The receipt printer 40 has a printing unit 44, and when a paper receipt is selected instead of an electronic receipt, the second control unit 21 of the store terminal 20 sends second selection information to the information processing device 50. The fifth control unit 51 of the information processing device 50 determines that a paper receipt is required based on the received second selection information and sends a print request to the receipt printer 40, and the fourth control unit 41 of the receipt printer 40 causes the printing unit 44 to print the print data based on the received print request. According to the POS system 1 described above, when a paper receipt is selected on the store terminal device 20, the information processing device 50 determines that it is a paper receipt and sends a print request to the receipt printer 40 to print the paper receipt.

[0047] Furthermore, in the POS system 1 of this embodiment, the first control unit 11 of the POS terminal 10 obtains the customer ID and sends it to the receipt printer 40, and the fourth control unit 41 of the receipt printer 40 sends the received ID to the information processing device 50. The fifth control unit 51 of the information processing device 50 determines that it is an electronic receipt based on the received ID. Next, the first control unit 11 of the POS terminal 10 generates print data and sends it to the receipt printer 40, and the fourth control unit 41 of the receipt printer 40 sends the received print data to the information processing device 50. The fifth control unit 51 of the information processing device 50 generates electronic receipt information based on the received print data by determining that it is an electronic receipt, and when it receives an electronic receipt request from the customer terminal device 30, it transmits the electronic receipt information.

[0048] According to the above-described POS system 1, when an ID is transmitted from the POS terminal device 10, the information processing device 50 can determine that it is an electronic receipt and transmit electronic receipt information to the customer terminal device 30.

[0049] The receipt system 2 of this embodiment also includes a receipt printer 40 having a fourth control unit 41, and an information processing device 50 having a fifth control unit 51. The receipt printer 40 is capable of communicating with the information processing device 50 and the POS terminal 10, and the information processing device 50 is capable of communicating with the receipt printer 40, the store terminal 20, and the customer terminal 30.

[0050] In the receipt system 2, the fourth control unit 41 of the receipt printer 40 receives print data from the POS terminal device 10 and transmits it to the information processing device 50, and the fifth control unit 51 of the information processing device 50 generates image data based on the received print data and transmits it to the store terminal device 20.
