In 1945, Leon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a covert listening device, rather than an identification tag, it is considered to be a predecessor of RFID because it was passive, being energised and activ. Who Invented RFID? While many innovators contributed to the development of RFID, historians typically grant the most credit to Charles Walton. He earns this distinction, in part, because he was the first person to hold a patent for the technology. In fact, he managed to obtain patents for nearly one dozen devices related to RFID.In 1945, Leon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information.

This chapter give an account of the development of radio-frequency identification (RFID) technology from its birth to the present day. The US patent 17744036, first filled in France in 1924, was certainly one of the very first, if not the first, documents that described the concept of RFID technology. G. Who Invented RFID?
