IDENTIFICATION CARD

摘要

Identification card, comprising a card body ( 1 ) with graphic identification information, wherein light emission means emit the identification information in visible or invisible light. The light emission means can consist of a flat light emitting diode ( 2 ) (FLED), for instance a Polymer FLED. The FLED can be connected with an internal or external electrical source. One or more layers ( 8 . . . 13 ) of the FLED that are needed for light emission can contain the graphic identification information or a part thereof, that is, the graphic identification information can be contained in the shape of that layer or layers and/or in the composition thereof. The graphic identification information can also be contained in the shape and/or intensity of the electrical field in, and the electrical current through, those layers ( 12 ), respectively, as effected by the electrical source.
