We propose an ID card and ID card system that makes inquiries.

[0016]

However, the above-mentioned I
The D card has the advantage that if the face photograph printed with magnetic toner is modified or replaced, the coded information will not match, making it impossible to use illegally. There is a problem that a terminal device becomes expensive because a reading device for reading two types of information, that is, the coded information of the face photograph itself and the ID information recorded on the magnetic stripe is required.

Further, it is desirable to increase the sharpness of the face photograph in order to enhance the security effect, but on the other hand, as the sharpness increases, the coding time becomes longer, and further, there are two types. For the reason that it is necessary to send information to the center device and collate it,
There is a problem that it takes a long time to obtain the matching result.

An object of the present invention is to provide an ID card with a high security effect that can read ID information with a single reading device and obtain a verification result in a short time, and an ID card using this ID card. Providing a card system.

[0019]

In order to achieve the above object, the ID card of the present invention prints a facial photograph of a cardholder using magnetic toner, and magnetically carries identification information in the facial photograph. Recorded and configured.

Further, the ID card system of the present invention has a face photograph of the card holder printed using magnetic toner, and the identification information is magnetically recorded in this face photograph.
