Restraining system including near field RFID detection

摘要

A restraining system comprises a restraining device including first and second interlockable parts that, when interlocked, restrain the system. The restraining system further comprises a passive RFID tag attached to the first part, and a passive RFID reader coupled to the second part for near field detection of the tag within a prescribed range of the second part.
