ABSTRACT:
A device for identifying authorization and triggering/enabling an action. The device comprises a base unit that detects identity information of a key unit, compares it with predetermined identity information and, if there is a match, triggers or enables the action. The base unit and the key unit each include synchronous generators outputting digital information that changes at predetermined time intervals. The key unit combines information of the digital generator with stored identification code to form a coded information item. The base unit codes the predetermined identity information with information from its own generator and compares this coded information with the coded information from the key unit. If the base unit detects the coded information, the action is triggered. The base unit outputs a signal, the key unit switches an antenna between matched and mismatched states, the antenna reflects the received signal, and base unit evaluates the reflected signal.
