Security document and process for producing a security document

摘要

The present invention relates to a security document 2 comprising a hologram 10 and an emitter device 20, 26 for emitting predetermined data in a noncontacting manner. The emitter device comprises an integrated circuit 20 and an antenna 26 connected to the integrated circuit. According to the invention, the emitter device is integrated into the hologram. In a preferred embodiment of the invention the integrated circuit is integrated into the substrate 14 of the hologram and the metal layer of the hologram forms the antenna which is connected to the integrated circuit. This combination means important improvement, from the point of view of product usage, and the occurrence of a hiding effect, a protection effect and the emission usage of the hologram for the radio frequency emitter device.
