ABSTRACT:
In an identification card to be read by a magnetic system, having two protective plates between which a plate-like data carrier is held and protected, this data carrier being made of a material acting upon a magnetic field and having zones providing the data and acting variously upon the magnetic field, it is proposed, in order to lengthen the life of the card as well as to provide greater security against counterfeiting, that the two protective plates be made from non-magnetizable metal, preferably sheet bronze, and that the data carrier be embedded between the two protective plates in a layer of adhesive, plastic or solder, the two protective plates being thereby firmly joined together.
