Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an ECR that enables credit transaction processing using a credit card.

[Summary of the invention] This invention is an ECR capable of processing credit transactions using a credit card, which reads the data recorded on the credit card before inputting product-related data, and reads the data recorded on the credit card while the product-related data is being input. By performing the authentication process with the credit card company, the time taken can be reduced compared to the case where the authentication process is performed after registering data regarding the product.

[Background Art] With the spread of credit cards, more and more supermarkets, department stores, and the like are processing transactions using credit cards.

Conventionally, when a customer purchases a product, the customer registers the details related to the product in HECR, and then uses a credit card authorization terminal (hereinafter referred to as CAT) to read the credit card data and record the total purchase amount. Enter the data and send it to the credit card company to determine the validity of the credit card,
Authentication is performed to determine whether the total amount of purchases made by the customer is less than or equal to a predetermined credit limit. However, if the ECR and CAT are provided in parallel, the total amount data registered in the ECR must be input into the CAT, which requires a lot of effort for the operator.

Therefore, recently, an ECR equipped with a CAT function has been put into practical use. ECR, which has such a CAT function, receives a credit card from the customer after the operator registers data regarding the product purchased by the customer, reads the data recorded on the credit card, and uses the read data as a credit card. The information is transmitted to the company for authentication processing. Then, when the credit card company informs you that the authentication process is normal,
I did the registration process for the first time and got 0.

[Problems to be solved by the invention] As mentioned above, in the ECR that has the CAT function, the credit card authentication process is performed after entering the data about the product, so the credit card company cannot authenticate the credit card. until the authentication process is completed.
The drawback was that customers had to wait longer.

Therefore, the primary objective of this invention is to provide an ECR that can reduce customer waiting time by performing credit card m1ffi processing while entering data regarding the customer's purchased items.

[Means for Solving the Problems] The ECR according to the present invention includes a card data reading means for reading data recorded on a credit card;
An input means for inputting data regarding the product, an authentication processing means for performing credit card authentication processing with a credit company while data regarding the product is being input, and a storage means for storing data regarding the product. and a control means that causes the storage means to store data regarding the input product in response to the authentication process being performed.

[Operation] The ECR according to the present invention performs credit card authentication processing in parallel while an operator is inputting data related to the product, thereby preventing the user from inputting data related to the product and performing the credit card authentication processing. The waiting time can be reduced compared to the case where

FIG. 1 is a flowchart for explaining the specific operation of one embodiment of the present invention. In particular, FIG. 1(a) shows the CPU 7
(7) Operation: FIG. 1(b) shows the operation of the CPU 10.

Next, with reference to FIGS. 1 to 4, a specific operation of an embodiment of the present invention will be described.

First, when a customer purchases a product and comes to the place where the ECR is located, the operator receives a credit card from the customer and inserts it into the card reader 5. The card reader 5 reads data recorded on the credit card and provides it to the CPU 10. The CPU 10 waits until card data is input from the card reader 5, and when the card data is input, it determines whether the card data is normal or not. That is, the CPU 10 performs card data formatting, parity checking, and the like. If the card data is normal, the card data is transmitted from the modem 11 to the credit company's host computer via a telephone line or a dedicated line.

The host computer of the credit card company performs authentication processing by checking whether the card is lost or not based on the transmitted card data. Then, if the card is valid, the amount of money that can be processed for credit transactions, that is, the credit limit given to the customer in advance, is transmitted to CPtJlo. C.P.
When U10 receives the credit limit from the credit company,
It waits until a data request command signal is sent from the CPU 7.

On the other hand, the operator causes the card reader 5 to read the data recorded on the credit card and immediately performs a registration process for the product purchased by the customer. That is, the operator inputs the department code of the product purchased by the customer using the department key 22. The CPU 7 waits until a key human signal is input from the keyboard 2, and presses the department key 2.
When it is determined that the operation No. 2 has been performed, registration processing is performed. That is, when a department code is input from the department key 22, the CPU 7 reads unit price data corresponding to this department code from the PLU file included in the RAM 9, updates the totalizer and the counter in the PLU file, and The amount data is registered in an itemizer (not shown). The operator sequentially inputs the department code of each product purchased by the customer. CPU 7 performs PL based on each department code input.
Search the U file, read out and register the unit price data of each product.

After the operator finishes inputting the department codes of all the products purchased by the customer, he operates the total key 241. C
P[J7 responds to the operation of the total key 241,
The sum of the amount data of the products registered up to that point is calculated. Further, the CPU 7 transmits a data request command signal to the CPU 10. When CPU 10 determines that a data request command signal has been given from CPU 7, it transmits to CPU 7 the authentication result and credit limit processed by the host computer of the credit company.

The CPtJ7 determines whether data has been sent from the CPU 10 or not, and if the data is sent, it receives the card data, the authentication result, and the credit limit. Then, it is determined whether the authentication result is normal or not. If the authentication result is normal, it is determined whether the total amount of products purchased by the customer is less than the credit limit. If the total amount is less than the credit limit, a message indicating that the transaction can be processed by credit card is displayed on the display 3, and the operator is informed to that effect.

The operator looks at the display on the display 3 and presses the card sales key 24.
Operate 2. When the CPU 7 determines that the card sales key 242 has been operated, it captures the card data and the sales amount into memory, and updates the sales amount in the card sales storage area of the RAM 9. Then, the printer 4 or slip printer 6 prints out the total amount, and the series of operations ends.

If the credit card transaction cannot be processed based on the authentication result by the credit company's host computer, or if the total amount exceeds the credit limit, a message to that effect is displayed on the display 3. The operator looks at the display, informs the customer that credit transaction processing is not possible, and requests cash payment. When the customer pays cash, the operator operates the cash sales key 243.

When the CPU 7 determines that the cash sales key 243 has been operated, the CPU 7 updates the total amount in the cash sales storage area of the RAM 9, prints the total amount using the printer 6 or the slip printer 6, and completes the series of operations.

[Effects of the Invention] As described above, according to the present invention, data recorded on a credit card is read before inputting data related to a product, and data recorded on the credit card is read while inputting data related to the product. Since the authentication process is performed in parallel, the input process and the authentication process can be performed in parallel, and the processing time can be shortened compared to the conventional case where the authentication process is performed after the input process is completed. As a result, the customer's time can be shortened and service can be improved.
