Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an electronic cash register with an authentication function, and in particular to an electronic cash register with an authentication function. Concerning a Nanako-style cash register with authentication and identification functions.

Summary of the Invention This invention is a transaction place using credit card 1! I!
It is a thunder type cash register that authenticates the possibility of a credit transaction based on the data read from the credit card in response to a command that the transaction is a credit card transaction. If credit transactions are possible, by processing credit transactions and registering input product data, it is no longer necessary to register product data and perform credit authentication separately, improving operator operability. Improve yourself.

Conventional technology The conventional electronic cash register (hereinafter referred to as ECR) is
The operator sequentially inputs the department code and amount data of each product purchased by the customer from the keyboard, and when the operator has finished inputting the department code and amount data of all products, operates the close key. Thereby, the total amount of the products purchased by that customer is calculated and displayed. The operator looks at the display and requests cash payment from the customer. The customer pays cash or high-denomination bills according to the displayed amount. When a large amount of banknotes are paid, the operator processes the change and hands the predetermined change to the customer.

As shown above, in the conventional ECR, transactions were processed in cash. However, recently, with the spread of credit cards, customers increasingly desire to process transactions using credit cards. When processing transactions using a credit card, a terminal device called a credit card authorization (CAT) is installed separately from the ECR, and when a customer wishes to process a transaction using a credit card, the operator A credit card is entrusted to the customer, the card reader included in the CAT reads the data recorded on the credit card, and the customer is requested to enter a PIN number from the bin pad. If the password included in the data read from the credit card matches the password input from the bin pad, the operator inputs the customer's total purchase amount data from the CAT keyboard. As a result, the CAT communicates with the host computer of the credit card company, authenticates whether or not a credit card transaction can be processed, and if possible, processes the credit card transaction.

Problems to be Solved by the Invention As mentioned above, in the past, ECR and CAT were provided separately, so when a customer wishes to process a transaction using a credit card, an operator operates ECR and then processes CAT@ This has the disadvantage that the operation is complicated.

Therefore, the main object of the present invention is to provide an electronic cash register with a credit authentication function that provides an ECR with a credit authentication function and simplifies the operator's complicated operations. .

Means for Solving the Problems The electronic cash register with credit authentication function according to the present invention includes an input means for inputting data regarding products and data for processing credit transactions recorded on a credit card. a reading means for reading, a credit instruction key for instructing that the transaction is a credit card transaction, a credit authentication means for authenticating whether the credit transaction is possible, and a credit transaction for processing the credit transaction if the credit transaction is possible. It consists of a processing means and a registration processing means for registering data regarding products for which credit transactions have been processed.

Operation: The electronic cash register with credit authentication function according to the present invention authenticates whether or not a credit transaction is possible based on the data read from the credit card when data related to a product is input and there is a transaction instruction using a credit card. If possible, credit transaction processing is performed, and data regarding the products for which credit transaction processing has been processed is registered. therefore,
When a customer wishes to process a credit transaction, the operator simply inputs data about the product, reads the data recorded on the credit card, and gives instructions for processing the credit transaction. The transaction processing data can be registered, and there is no need to operate both ECR and CAH as in the past, which improves operability.

FIG. 5 is a diagram showing a key operation sequence for registration processing and payment processing, and FIG. 1 is a flowchart for explaining the specific operation of one embodiment of the present invention. Figure <a> shows the operation as an ECR, and FIG. 1(b) shows the operation as a CAT.

Next, with reference to FIGS. 1 to 5, a specific operation of an embodiment of the present invention will be described.

First, the operator selects mode 3 by switching the mode changeover switch 11. Then, the customer inputs the department code of the purchased product using the department key 12, and inputs the price data of the product using the numeric keypad 13. This operation is repeated until the department code and price data of all products purchased by the customer are entered. Each time the department code and amount data for each product are input, the CPIJ 5 causes the display 3 to display the department code and amount data, and causes the printer 4 to print them on the receipt. After entering the department codes and price data for all the products purchased by the customer, the subtotal key 143 is operated. When the subtotal key 143 is operated, the CPU 5 calculates the sum of the amount data of the products input so far, displays it on the display 3, and causes the printer 4 to print it on the receipt.

If the customer wishes to process a transaction using a credit card, the operator will collect the credit card from the customer and
A card reader 2 reads data recorded on the credit card for credit transaction processing, and the customer is prompted to input a personal identification number from a bin pad (not shown). The CPU 5 determines whether or not the password entered from the bin pad matches the /ζ password read from the credit card. If they match, the display 3 will display that fact. The operator then inputs the total amount displayed on the display 3 using the numeric keypad 13 and operates the credit key 141. In response to the operation of the CPU 5t credit key 141, the credit card data and credit amount data read from the card reader 2 are transmitted to the CPU 8.

The CPU 8 constantly determines whether or not data has been transmitted from the CPU 5, and when it determines that data has been transmitted from the CPU 5, it sends the credit card data and credit card to the host combination coater of the credit card company via the modem 20. Transmit amount data. The host combination 1-1 of the credit company performs authentication processing based on the transmitted credit card data and credit amount. That is, it is determined whether an amount greater than the credit amount is deposited in the customer's bank account. If an amount equal to or greater than the credit amount has been deposited in the corresponding bank account, the CPLI 8 transmits a command to enable the credit transaction to the CPIJ 8. The CPLI 8 indicates that the credit transaction is possible from the host combi coater via the modem 20. It is determined whether a command indicating the credit transaction has been sent or not, and if the credit transaction cannot be performed, that fact is transmitted to the cptg. If the credit transaction is possible, the CPIJ 8 stores the credit amount data transmitted from the CPLI 5 in the credit totalizer 101 of the RAM 10 and increments the credit counter 102 by 1.

On the other hand, after the CPU 5 transmits the credit amount and credit card data to the CPIJ 8, the CPU 5 continuously
It continues to determine whether data has been transmitted from s.

When data is transmitted from the CPU 8, it is determined whether a credit transaction is possible. If credit transactions are possible, credit totalizer 71 in RAM 7
The total amount is memorized in the credit counter A2.
is incremented by 1 and the total amount is printed on the receipt by the printer 4. Then, the registration of the credit transaction data is completed.

If a credit transaction is not possible, the customer is requested to pay in cash. When the customer pays in cash, the data of the total amount paid by the customer is entered manually from the numeric keypad 13. Then, the CPIJ 5 stores the input customer payment amount data in the cash totalizer 73 of the RAM 7 and increments the cash multiplier 74 by one. Then, the end print is performed by the printer 4, and the series of operations ends.

Effects of the Invention As described above, according to the present invention, when a customer wishes to process a transaction using a credit card, the data recorded on the credit card is read and bypassed, and a transaction instruction using the credit card is given. This allows the operator to authenticate using a credit card, and also to register 9 IU of credit transaction processing data.
There is no need to operate both T. This eliminates the complexity of operator operations.
