Abstract
A transponder/interrogator system for remotely identifying objects. The interrogator emits optical pulses to activate the transponder. Upon such activation, the transponder emits a unique code in the form of optical pulses in accordance with a program stored in its memory. The interrogator receives the optical pulses from the transponder and decodes them. The decoded information is then supplied to peripheral equipment which run various status checks on the object identified and takes appropriate action.
