The IC card C may be placed on the card placement unit 10 before the customer is prompted by the operator.
[0037]
The electronic money settlement process is executed on condition that the registration mode is set by operating the control key 5. As shown in FIG. 7, first, the electronic money settlement process waits for reading by the barcode scanner 9 or input of a product code by a numeric key or the like (N in step S1). At this time, a standby screen as shown in FIG. 8A is displayed on the display 8 on the customer side. Normally, a commercial screen for promoting sales of commodities or the like is displayed as the standby screen.
[0038]
When the product code is input (Y in S1), the product master file of the HDD 44 is searched based on the input product code, and the sales processing data of the product determined by inputting the quantity is stored in the sales buffer of the RAM 34 or the HDD 44. A sales process for writing in a sales file or the like is executed (S2). Then, in the electronic money settlement process, steps S1 and S2 are repeated until the subtotal key in the keyboard 4 is pressed (N in S3).
[0039]
Next, when it is determined that the subtotal key has been pressed (Y in S3), the total sales amount is calculated and displayed on the displays 7, 8, and written into the RAM 34 of the POS terminal 1 (S4). Thereafter, the payment method is selected by the operator pressing a payment key such as an electronic money key, a cash key, or a credit key. First, the electronic money settlement process determines whether the electronic money key is pressed (S5).
[0040]
If it is determined that the electronic money key has not been pressed (N in S5), it is determined whether another payment key such as a cash key or a credit key has been pressed (S6). If it is determined that another payment key has not been pressed (N in S6), the electronic money payment process returns to step S5, and repeats steps S5 and S6 until a payment method is selected. If it is determined that another payment key has been pressed (Y in S6), other payment processing such as cash payment processing or credit payment processing is executed in accordance with the pressed cash key or credit key (S7).
[0041]
If it is determined that the electronic money key has been pressed (Y in S5), it is determined whether an ID code can be read from the IC card C (S8: determination means). At this time, if the IC card C has been previously placed on the card placement unit 10 or if the IC card C has been held over the card placement unit 10 by the customer, the non-contact card of the POS terminal 1 The ID code is read from the EEPROM 25 of the IC card C into the RAM 34 of the POS terminal 1 by the reader / writer 12 (Y in S8).

[0047]
Next, it is determined whether or not the remaining amount is equal to or greater than the total sales amount (S14). If it is determined that the remaining amount is equal to or greater than the total sales amount (Y in S14), the total sales amount is subtracted from the remaining amount read into the RAM 34 of the POS terminal 1 to calculate an updated remaining amount, and the contactless card reader / writer is written. 12 writes the updated balance as the balance data in the EEPROM 25 of the IC card C (S15).
[0048]
Finally, closing processing such as writing of sales processing data in the sales file or the like of the HDD 44 or issuing a receipt for issuing a receipt from the receipt issuing port 6 is executed (S16), and the electronic money settlement processing ends. Note that the electronic money settlement process may wait between the step S15 and the step S16 until the closing key is pressed, and if it is determined that the closing key is pressed, the closing process of the step S16 may be executed.
[0049]
If it is determined in step S14 that the remaining amount is not equal to or larger than the total sales amount (N in S14), the remaining amount read into the RAM 34 of the POS terminal 1 is subtracted from the total sales amount to calculate a shortage amount. The insufficient amount is written into the RAM 34 of the POS terminal 1, and the non-contact card reader / writer 12 writes the remaining amount of 0 yen as the remaining amount data into the EEPROM 25 of the IC card C (S17). Finally, the shortage is displayed on the displays 7 and 8 (S18), and thereafter, another settlement process, for example, a cash settlement process is executed (S7).
