To easily judge the identification of card users or the validity of use by giving a fingerprint to a card or storing the fingerprint in an electronic circuit as the collation factor for use of the card, and judging the identification of the user or the validity of the use by the fingerprint.

Necessary items 2 such as an owner's name, identification number are filled in by means such as printing or embossing on the surface of a card 1, and an owner's fingerprint 3 is given. The fingerprint 3 is given by a method for laminating a card base made, for example, of synthetic resin with fingerprint collected by using vermillion inkpad to the base material of sheet, or a method having the steps of using a resin film as a base, printing the fingerprint collected to a print sheet coated with photosensitive material (photosensitive emulsion) on the surface, developing and fixing it. A magnetic recording layer 4 formed by coating the rear surface of the card 1, for example, with iron oxide powder, other necessary items are filled in, and the shade of the fingerprint 3 is, for example, magnetized, and read it.
