    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.
