Abstract
An inductive identification card on which a card holder's identifying information is recorded in order to recognize the holder's identity via a visual inspection. The identification card is provided with a sensor film on the surface having sensor points which are distributed on its exterior, blocking points corresponding to the identifying information on the identification card, and locally changing electrical responses of sensor points in advance so that different response signals corresponding to detective signals which are applied to the sensor film are generated by the blocking points and peripheral regions, respectively. Authenticity of the identification card and the card holder's identity are recognized by determining locations of response signals.
