Abstract
A security access system performing identification, verification and authorization is provided. In one embodiment, a security access system is disclosed. The security access system comprises, a radio frequency identification (RFID) activator loop integrated in an access road, a loop reactance sensing circuit, an RFID personal identification tag, an imaging device and a verification system. The loop reactance sensing circuit is adapted to measure the reactance of the RFID activator loop to determine the presence of a vehicle. The RFID personal identification tag is adapted to transmit identification data regarding the person it is associated with in response to the RFID activator loop. The imaging device is adapted to record an image of the person. The verification system is adapted to process the identification data of the RFID identification tag and produce an image of the person from a database associated with the identification data.
