A read / write device for an information storage card having a forgery and tamper proof function.

Recently, information storage cards for various purposes have been developed and used. Especially, the highway toll card, which has been started for the purpose of shortening the fare payment time for the toll amount, is a kind of prepaid card, eliminating the hassle of preparing the change of cash customers. It is a card that combines the benefits of the user side and the publisher's advantage of enabling the increase of sales by the expected effect of advertising revenue due to the sales effect of the card and the advertising media, and the utilization rate is increasing rapidly. The toll booths are expanding this expressway toll card.

On the other hand, the expansion of information storage cards such as expressway pass cards, etc., may lead to problems such as card forgery and tampering due to the increase of users. By providing various security functions, countermeasures against counterfeiting and tampering with the card have been taken.

Background Art Conventionally, a lamination structure is used in a magnetic layer, a method of punching a magnetic card, and the like have been commonly performed for the purpose of preventing forgery and alteration of an information storage card using magnetic. However, these structures are relatively easily copied or deceived by thieves and are not sufficient to deter attempts to illegally copy or alter the card.

Looking more closely at the techniques of anti-counterfeiting and tampering, it is divided into the following two cases. The first is a technique of visual identification, that is, the identification of the eye. For example, fingerprints, holograms, and the like are used to discriminate the authenticity of the human eye by performing special processing that is difficult to forge on a card. While it can be easily distinguished without the need for a dedicated machine, it has a feature that can be produced only with a predetermined ink.

The second is a discrimination technique based on a mechanism, and since a card reader can be used to determine the information of a card through a specific reader, the code system cannot be determined by the eye. However, a high technology is required for a method of recording / reproducing information on a card. Have The discrimination technique by this mechanism is a technique of matching a card with a device for identifying the same, that is, information that can be recognized by a specific sensor without being visible to a human part on a part of the card and recorded on the device side. The authenticity is determined according to the information present or the correspondence between the information and the magnetic information of the card. For example, a stealth mark, a bar code, etc., and a technology specially designed to read certain information, Otherwise, it is impossible to record and reproduce information at the source. In addition, the software may encrypt information using specific software so that even if it can be reproduced in an illegal manner, it does not know what it means.

However, according to this universal conventional technology, the internal structure of the information storage card may be further complicated by known means, and the complexity and the price of the reader / writer for reading and writing into or from the card are increased. It contains various problems such as causing.

Accordingly, an object of the present invention devised to solve such a problem is to facilitate the forgery and tampering of an information storage card by any unauthorized person, while easily increasing its complexity as a read / write device without increasing the complexity of the device. A read / write device for an information storage card having a forgery and tamper proof function that can determine / confirm authenticity.

Another object of the present invention is to easily determine the authenticity of the card as a read / write device and to identify the authenticity of the card with human eyes, thereby preventing counterfeiting and tampering of the information storage card more effectively. A read / write device for an information storage card having a forgery and tamper proof function.
