An enhanced identification tag (20) produces an identification (ID) signal(38) carrying identification information, capable of being interpreted by an electronic reader device (30). An identification tag (20) in accordance with the invention is characterized by a flexible substrate (22), programmable encoder circuitry (28) formed on said substrate (22) defining identification information, an antenna (24) and signal generator circuitry (26) carried by said substrate (22) responsive to said encoder circuitry (28) for applying a radio frequency signal bearing said identification information (36) to said antenna (24). A preferred tag is fabricated using a printing process to mark a conductive pattern, e.g., comprised of a conductive ink based on silver, carbon, etc., on a flexible substrate (22), plastic type material. In a typical application, the flexible substrate (22) is then preferably used to form a wrist band that can be used to identify an individual to permit, deny or otherwise determine the level of access to an area, e.g., a concert, a work area or other restricted environment. |
