Is written in the predetermined recording area.

[Action]

In the magnetic recording card terminal device which reads and rewrites the data of the magnetic recording cards by recording the addition / subtraction information 1 on the magnetic recording medium of the magnetic recording card, based on the addition / subtraction information 1 of each magnetic recording card. And subtraction or addition can be performed, and it becomes unnecessary to switch the subtraction or addition mode by some operation on the terminal device side.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a diagram schematically showing a structure of data recorded on a magnetic recording medium of a magnetic recording card according to the present invention.

This magnetic recording card has a recording area in which an identification code of the card, that is, information indicating which prepaid card terminal device can use this card, is recorded, and then this magnetic recording card is recorded on a magnetic recording medium. There is a recording area for recording addition / subtraction information 1 indicating whether the card is a type of performing subtraction on the stored data (prepaid card) or an addition type (service card).

Next, there is a recording area for recording a unit value 2 (unit amount of money, unit frequency) for subtraction or addition, and a recording area for recording the code of the issuing terminal device of the magnetic recording card and the usable amount of the card (card balance). ), A frequency, or in the case of an addition type card, there is an area for recording the number of additions.

Next, FIG. 2 shows a circuit configuration of a magnetic recording card terminal device for reading and rewriting data of the magnetic recording card recording the above-mentioned addition / subtraction information.

The input / output unit 11 is an interface unit for reading / rewriting a magnetic recording card, and conveys the inserted magnetic recording card to an internal reading / writing unit to read / write data.

The CPU 12 is a central processing unit that performs overall control according to the control program of the built-in ROM. When it detects that a magnetic recording card is inserted in the input / output unit 11, it reads the card data and executes a subtraction type card (prepaid card). ) Or
Alternatively, it is determined whether the card is an addition type card (service card). Then, the issuing terminal code, the balance of the card, the number of times, etc. are read, necessary data is stored in the memory 17, and the display unit 1 composed of an 8-digit 7-segment LED
Display the card balance etc. in 3.

The ten-key pad 14 is a key for inputting the amount and the number of additions and subtractions when subtracting or adding the amount and the number of times different from the unit value recorded on the card from the card balance or the number of times displayed on the display unit 13. When a numerical value is input from the ten-key pad 14 and the execute key is operated, the type of the magnetic recording card used is discriminated and subtraction or addition is automatically performed.

The thermal printer 15 is capable of printing 24 digits, and when the prepaid card is used at the time of payment, it is possible to print the deduction amount and the like as needed.

The line interface 16 connects a plurality of magnetic recording card terminal devices via a dedicated line or a telephone line,
It is an interface circuit for transmitting and receiving data processed by each terminal device.

In the magnetic recording card terminal device having the above configuration,
When a magnetic recording card is inserted from the input / output unit 11, first, the addition / subtraction information 1 on the magnetic recording medium is read to determine whether the used card is a prepaid card or a service card. Then, subsequently, the unit value, the issuing terminal NO and the balance (frequency) of the card recorded are read.

When subtracting the balance or the number of times recorded on the magnetic recording card, the addition / subtraction information is "1".
However, if "0" is written in advance as addition / subtraction information when performing addition, if the read addition / subtraction information 1 is "1", it is determined that the card is a prepaid card and the unit amount is subtracted from the card balance. Then, the subtraction result is again written in the magnetic recording card, and if the addition / subtraction information 1 is "0", it is determined that the card is a service card and the unit number is added to the read number.

In this way, by recording the data indicating the balance of the magnetic recording card and the addition / subtraction information 1 indicating the contents of calculation performed on the data, the magnetic recording card terminal device side when processing the above-mentioned two types of cards. The card can be processed more quickly without the need for a special switching operation.

In addition, if the amount of money to be subtracted or added (unit amount of money) is predetermined, and if those amounts of money change under certain conditions, etc., according to the conditions given to the card for each magnetic recording card. By recording the unit amount of money recorded, the operator does not need to judge the condition when performing subtraction or addition, and the operation of inputting the corresponding subtraction value or addition value is unnecessary, and card processing can be performed more efficiently. .

[Effect of device]

According to the present invention, when there are two types of magnetic recording cards of a type that subtracts the written data and a type that performs the addition, a special switching operation is performed on the terminal device side. Since it is possible to read and rewrite these two types of cards, it is possible to quickly process many types of magnetic recording cards.
