In such a configuration, a function of causing the microcomputer 30 to execute a program stored in the HDD 43 built in the POS terminal 1 will be described. In the present embodiment, a description of the same processing as that performed by the conventional POS terminal is omitted.
[0035]
First, electronic money settlement processing by the IC card C to which electronic money has been deposited will be described with reference to FIGS. Here, FIG. 8 is a flowchart schematically showing the flow of the electronic money settlement process.
[0036]
In the electronic money settlement processing, normally, when the customer is prompted by the operator, the IC card C is held over the card placement unit 10 by the contactless card reader / writer 12 so that the IC card C is Data reading / writing is performed, but the present invention is not limited to this. 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. 8, 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. 7A is displayed on the display 8 of the customer. 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 43 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 43. A sales process for writing in a sales file or the like is executed (S2). Then, in the electronic money settlement processing, 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, it is determined whether the electronic money key is pressed (S5).
[0040]
Note that, during the electronic money settlement process from the input of the product code in step S1 to the selection of the settlement method in step S5, the customer presses the card payment key 8b on the standby screen (FIG. 7A). The electronic money settlement screen is displayed on the display 8 (see FIG. 7B), and a flag is set. When this flag is set, the electronic money settlement process determines that the electronic money key has been pressed. Therefore, the customer can select payment by electronic money as a payment method by pressing the card payment key 8b, and there is no need to verbally inform the operator of payment by electronic money.
[0041]
When it is determined that the electronic money key has not been pressed (for example, when the flag is not set or when the electronic money key has not been pressed by the operator) (N in S5), another key such as a cash key or a credit key is used. It is determined whether the settlement key is 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).
[0042]
When it is determined that the electronic money key has been pressed (for example, when the flag is set or when the electronic money key is pressed by the operator) (Y in S5), the ID code is read from the IC card C. It waits (N in S8). At this time, if the IC card C has been previously placed on the card placement unit 10, the ID code from the EEPROM 25 of the IC card C is stored in the RAM 34 of the POS terminal 1 by the non-contact card reader / writer 12 of the POS terminal 1. Read (Y in S8).
[0043]
On the other hand, if the IC card C has not been previously placed on the card placement unit 10, the operator is prompted to hold the IC card C over the card placement unit 10, and the customer responds accordingly. When the IC card C is held over the card mounting portion 10, 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 non-contact card reader / writer 12 of the POS terminal 1 (Y in S8). If the card payment key 8b is pressed and the flag is set, the flag is cleared by reading the ID code into the RAM 34 of the POS terminal 1.
[0044]
Thereafter, authentication is performed to determine whether or not the IC card C is a legitimate card (S9). More specifically, it is determined whether or not the ID code read into the RAM 34 of the POS terminal 1 matches the authentication code stored in the ROM 33 of the POS terminal 1.
[0045]
If it is determined that the IC card C is not a legitimate card (N in S9), an error is notified to the operator and the customer, that is, the fact that the card is not a legitimate card to the displays 7, 8 and the red LED 15b for several seconds. (S10) Then, the electronic money settlement process returns to step S5, and waits until a settlement method is selected again (N in S5, N in S6).
[0046]
When it is determined that the IC card C is a legitimate card (Y in S9), the non-contact card reader / writer 12 reads the balance data from the EEPROM 25 of the IC card C into the RAM 34 of the POS terminal 1 (S11).
[0047]
Next, it is determined whether or not the remaining amount is equal to or greater than the total sales amount (S12). If it is determined that the remaining amount is equal to or greater than the total sales amount (Y in S12), the total sales amount is subtracted from the remaining amount read into the RAM 34 of the POS terminal 1 to calculate an updated balance, 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 (S13).
[0048]
Finally, a closing process such as writing of sales processing data into the sales file or the like of the HDD 43 or issuing a receipt for issuing a receipt from the receipt issuing port 6 is executed (S14), and the electronic money settlement processing ends. The electronic money settlement process may wait between the step S13 and the step S14 until the closing key is pressed, and if it is determined that the closing key is pressed, the closing process of the step S14 may be executed.
[0049]
If it is determined in step S12 that the remaining amount is not equal to or greater than the total sales amount (N in S12), 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 shortage is written into the RAM 34 of the POS terminal 1 and the non-contact card reader / writer 12 writes the remaining balance of 0 yen as the balance data into the EEPROM 25 of the IC card C (S15). Finally, the shortage is displayed on the displays 7 and 8 (S16), and thereafter, another settlement process, for example, a cash settlement process is executed (S7).
[0050]
Next, an electronic money balance inquiry process for inquiring the balance of the electronic money deposited in the IC card C will be described with reference to FIGS. Here, FIG. 9 is a flowchart schematically showing the flow of the electronic money balance inquiry process.
[0051]
As shown in FIG. 9, the electronic money balance inquiry process waits until the balance inquiry key 8c is pressed (N in step S20). At this time, a standby screen as shown in FIG. 7A is displayed on the display 8 of the customer. Normally, a commercial screen for promoting sales of commodities or the like is displayed as the standby screen. When the customer presses the balance inquiry key 8c on the standby screen, the electronic money balance inquiry process waits until the ID code is read from the IC card C (N in S21).
[0052]
At this time, if the IC card C has been previously placed on the card placement unit 10, the ID code from the EEPROM 25 of the IC card C is stored in the RAM 34 of the POS terminal 1 by the non-contact card reader / writer 12 of the POS terminal 1. Read (Y in S21).
[0053]
On the other hand, if the IC card C has not been previously placed on the card placement unit 10, the operator is prompted to hold the IC card C over the card placement unit 10, and the customer responds accordingly. When the IC card C is held over the card mounting portion 10, 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 contactless card reader / writer 12 of the POS terminal 1 (Y in S21).
[0054]
Thereafter, authentication is performed to determine whether or not the IC card C is a legitimate card (S22). More specifically, it is determined whether or not the ID code read into the RAM 34 of the POS terminal 1 matches the authentication code stored in the ROM 33 of the POS terminal 1.
[0055]
If it is determined that the IC card C is a legitimate card (Y in S23), the non-contact card reader / writer 12 reads the balance data from the EEPROM 25 of the IC card C into the RAM 34 of the POS terminal 1, and stores the balance for several seconds. Is displayed on the touch panel 8 (S23), and the electronic money balance inquiry process ends. At this time, an electronic money balance inquiry screen as shown in FIG. 7C is displayed on the display 8. Therefore, the customer can perform the balance inquiry of the IC card C by himself / herself by pressing the balance inquiry key 8c, and there is no need to ask the operator for the balance inquiry of the IC card C.
[0056]
If it is determined in step S22 that the IC card C is not a legitimate card (N in S22), an error is displayed to the operator and the customer, that is, the display 7, 8 and the red The light-emitting LED 15b is notified (S24), and the electronic money balance inquiry process ends.
[0057]
It should be noted that the electronic money balance inquiry processing can be performed even during the sales processing in the electronic money settlement processing. Thus, while the operator is performing the sales process using the POS terminal 1, the customer can check the balance of the IC card C in which the electronic money has been deposited and confirm the balance of the IC card C before payment. it can.
[0058]
As described above, in the present embodiment, the touch panel 8a is provided on the screen of the display 8 on the customer side, and the non-contact card reader / writer 12 reads / reads data from / to the IC card C by operating the touch panel 8a.
