Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention records fee information in advance and reduces the fee information each time it is used.
The present invention relates to a card and an issuing device for the card, in which the amount of the remaining amount can be visually checked through a hole.

[0002]

2. Description of the Related Art A prepaid card system is available in which a card in which fee information is magnetically recorded is purchased in advance, the fee information is reduced and rewritten each time the card is used, and the remaining amount of money can be used. Widely used in various industries. When the same system is used in various industries, when the card is issued, the fee data is recorded together with the information such as the code of the industry that can identify the card. By reading and identifying this data, it was possible to differentiate between industries. Also, with respect to fee data, different fee information is not recorded on the card by a bar code printed on the card.

[0003]

However, in this type of issuing method, only important information for discriminating between industries is magnetically recorded. Therefore, various operations can be performed by operating the issuing device illegally. There was a risk that it would be possible to issue cards of the industry. In addition, the bar printed on the card
Since the code is visible, the relationship between the bar code and the charge information was naturally known, increasing the possibility of bar code forgery. That is, it was possible to forge by purchasing a large amount of low-priced cards used in a certain industry and replacing them with expensive cards of another industry.

In view of these drawbacks, the present invention makes it impossible to falsify card data, and limits the issuance of cards of other industries to prevent the issuance of cards by unauthorized operation. The present invention aims to provide a card and a card issuing device.

Further, the verification information generating section, the code demodulating section, the charge comparing section and the code comparing section are constituted by a one-chip microcomputer in a mask ROM.

[0007]

In the present invention, the card is connected to the car beforehand.
Group code that determines whether or not the device is issued
The issue amount code that determines the range of issue amount is scrambled under a predetermined first algorithm and printed as an identification code that can be identified by invisible light, and the balance of the card is displayed. A perforation detection section that can be identified by invisible light is printed at a position corresponding to the perforation section to be displayed as a guide. To the card issuing device, charge data to be stored in the card, card specific data, etc. are input from the data input section and the setting is completed.

The group code and the issue amount code are separated from the card section by the first algorithm, and the internal identification code and the group code stored in the card issuing device are coded. The card comparison unit compares them and if they do not match, the card is discharged as an unissueable card. If they match, the charge comparison section
The issuer is compared with the issue amount code, and if the charge data to be recorded in the card is within the issue amount permitted by the card, the issue is permitted, otherwise the issue is not possible. Discharge as a card.

When the issuance is permitted, the fixed data including the card specific data is recorded in the first magnetic layer by the first recording control section, and the charge information and the card are recorded by the verification information generation section. -Variable data including verification information and charge data generated from the specific data of the card under a predetermined algorithm is recorded on the second magnetic layer by the second recording controller, and the card is recorded. The issuing process ends.

Therefore, even if the issuing device is illicitly operated and a card of a business type that is not permitted by the issuing device is issued, the issuing can be disabled, and the charge data can be changed. If it is out of the range permitted by the card, it can be considered as unissueable.

Further, generation of verification information, code demodulation,
Since the comparison of charges and the comparison of codes are carried out in the one-chip microcomputer in the mask ROM, it is possible to enhance the confidentiality without security information on the signal line.

The recorded information of the card is card-specific data, charge data, and their data which are different for each card.
Since it is composed of the verification information generated by the predetermined second algorithm from the data, even if the fee data is falsified, the verification information does not match and it cannot be used.
