Abstract
A transponder/interrogator system for remotely identifying objects. The interrogator emits infrared pulses to activate and remotely clock the transponder. Upon such activation, the transponder emits in synchronism with the interrogator pulse a unique code in the form of infrared pulses in accordance with a program stored in a recirculating shift register. The interrogator receives the infrared pulses from the transponder and may be associated with various code utilization devices as described herein.
