security box system - has key with light emitting diode and photo electric receiver that provide information transfer link with read/write unit

摘要

A security box system is accessed using a key that includes electronic circuitry. The key has a light emitting diode (11) and a photo electric receiver (12) that provide an information transfer link with a read/write unit (20) that the key is inserted into. The metallic stem of the key provides a means of transfer for electrical power (13, 23). The key has a memory (14) that contains identification code data that is transferred to the reader and is relayed by the controller (25) to an external unit. USE/ADVANTAGE - Has multifunction built in to provide access control.
