The present invention relates to a cash register having a credit card verification function.

Recently, as credit cards, which have a function of cash substitution, are becoming more common, the problem of using them increases. In particular, the deficiencies caused by the use of a canceled card or the use of a third party card are not significant. Therefore, a means of checking the validity of the credit card was needed. Currently, credit card companies can be inquired directly by telephone, or by installing a magnetic record () check device separately to check the contents of the card. We have been determining the validity of the card.

However, when verifying by phone, there is a problem point in the accuracy and time required for checking, and in the case of installing a separate checking device, there is a disadvantage in that the installation cost is high.

The present invention improves the shortcomings of the above-mentioned verification method, and it is possible to accurately determine whether there is a possibility of cash substitution of a credit card even if a separate verification device is added by adding a credit card verification circuit to an existing cash register. It is. Hereinafter will be described in detail the configuration and effect of the present invention.

The present invention provides a data converter 3 connected to the magnetic reading device 2 inside the cash register 1, and the central controller 4 and the existing keyboard 5 in the data converter 3. After connecting the line converter (8) to the central control unit (4) and install the telephone 10 on the outside of the converter (8), the existing display device (6) and RAM (7) and The printer 9 is structured to be connected to the central controller 4.

Reference numeral 11 denotes a key for value and value, 12 key for item registration, 13 subtotal key for indicating the sum of the amount of goods, 14 credit card inlet, 15 credit key, 16 cash, 2, 17 The operation key 18 is a credit card company, and cc is a credit card.

1 is a schematic diagram of the present invention having the above-described structure, and FIG. 2 is an appearance of a keyboard unit. When a customer purchases a product, the clerk once has the amount and the numerical key 11 of FIG. The item registration key 12 is operated to input the amount of the item and the item to the cash register 1, and the numerical values are displayed in the W and K columns of the display device 6, respectively. Thereafter, when the customer submits a credit card (cc) having a cash substitution function in place of cash, the submitted credit card (cc) is inserted into the credit card inlet 14, and immediately the MAGNETC MEMORY READER (2). The account number, password, and personal information contained in) are read. Each read symbol is converted into a required signal by the data converter 3, and the data converter 3 performs the following functions. That is, after checking the sensor 26 for determining the correct insertion of the credit card cc as the signal d, and if there is no abnormality, the position control mechanism 21 of the head 20 through the signal line a. Emits a signal for moving the signal, which is amplified by the amplifier 25 and then transmitted to the control mechanism 21. The electrical signal from the head 20 is converted into a digital signal compared with the reference voltage in the voltage comparator 23 via the multi-stage filter 22, and combined with the signal b from the central controller 4, As the signal c is reached, the central controller 4 is reached again, which is stored in the corresponding memory by an internal program and used when necessary. The above briefly describes the operation path of a moment, but in reality it repeats while moving the head 20 until all necessary data is read.

The information extracted through the above process is input to the line converting apparatus 8 together with the amount and item number data from the keyboard 5, and if there is nothing wrong with the above process, the normal display unit 19 turns on. At this time, the clerk manipulates the amount and the numeric keys 11 of the keyboard unit 5 to input the call number of the credit card company 18 into the line converting device 8 through the central controller 4. . This line converter 8 is a modem or N. Seed. It consists of circuits such as MODEM and NCU, and pulses the calling number to the telephone 10 so that the telephone line can be dialed according to the calling number, and thus the telephone 10 is a credit card company. (18) is called to transmit the converted signal of the information.

The credit card company 18 reads and records the information in a normal data processing method such as ON-LINE, and if there is no error, a cash substitution command is sent to the telephone line. It is delivered to the cash register 1. The transferred cash substitute command signal is processed by the central controller 4, and turns on the credit key 15. FIG.

After the verification process of the credit card cc is completed in this way, the transaction is finished after being printed by the printer 9 such as the subtotal amount and the item according to the processing of the general cash register 1.

As described above, the present invention adds the software of the credit card verification function (SOFTWARE) to the existing cash register 1 provided with the central control unit (CPU), and does not need to install a separate verification device by adding some components. It is easy to check whether the credit card is replaced with cash, improve the reliability of the cash register, reduce the burden of installing additional equipment, and promptly verify the service. There are advantages such as being able to increase the efficiency significantly.
