TITLE IDENTIFICATION SYSTEM ABSTRACT OF THE DISCLOSURE A passive integrated transponder (PIT) is attached to or embedded in an item to be identified. It is excited via an inductive coupling from an interrogator. The PIT responds to the interrogator via the inductive coupling with a signal constituted by a stream of data unique to the identified item. The signal is in the form of two different frequencies, a shift from one to the second representing a data "one", and a shift from the second frequency to the first frequency representing a data "zero". The responsive signal is then detected and processed for utilization in a data storage or display device.
