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 industry code to identify the card, and the card records this information. Differentiating between industries was possible by reading and identifying the data. Also, regarding charge data, different charge information is not recorded on the card by a bar code printed on the card.

[0003]

However, this type of issuing method only magnetically records important information for differentiating between different industries, so it is possible to illegally operate the issuing device. There was a fear that cards of various industries could be issued. Also, since the bar code printed on the card is visible, the relationship between the bar code and the charge information is naturally known, increasing the possibility of bar code forgery. It was In other words, it was possible to counterfeit by purchasing a large amount of low-priced cards used in one industry and recreating them into high-priced cards of another industry.

In view of such drawbacks, the present invention makes it impossible to falsify card data, and
It is an object of the present invention to provide a card processing device in which the use of other par value cards is restricted.

Although the fixed data section 12 and the variable data section 13 are provided on one track in the above embodiment, the two heads may have different track configurations. Although the magnetic layer has been described as an example of a two-layer card, it goes without saying that a card provided with a shield layer on the magnetic layer may be used.

In this embodiment, the code information area is formed by partially printing the reflection layer, but the reflection layer is printed over the entire area of the code information area. The code information section may be formed by printing a partially hollowed absorption layer on the layer.
