Alfred R Koelle, Jeremy A Landt: System for identifying particular objects. Amtech Corporation, Ellsworth R Roston, Charles H Schwartz, April 19, 1988: US04739328 (230 worldwide citation)

A reader interrogates an object. The object has a tag with a data source such as a read-only memory (ROM) which produces an identifying sequence of binary 1's and 0's in an individual pattern and transmits these signals to the reader. Each "1" or "0" is converted to a plurality of signal cycles at f ...
