Identification card with covered coding - has two layers bonded together with coding on inner surface that may be read by infra red radiation

摘要

An identification card is designed from multiple layers with an internal coding that is read using infra-red devices. The top layer of the card (1) is produced from a transparent material with the underside coated to allow only infra-red transmissions through. An information sector (3) remains transparent. The bottom layer (5) has a metal deposition (6) with a coded area (7) that may be read using infra-red sensors. Numerical information is printed in one region and may be directly viewed. The two layers are bonded together and the card holders name printed on the top surface. 3.
