5. RFID History Radio-frequency identification (RFID) uses radio waves to exchange data between a reader and an attachment to an object. The first version of the technology was created in 1945 by Leon Theremin. Originally, it was designed as an espionage tool for the soviet union. Used as a covert listening device, the sound waves were directed through a diaphragm. This altered the shape of the diaphragm, which modifies the reflected radio frequency. This early predecessor did not have an identification tag.
6. RFID History (Con’t) 1945 - Leon Theremin develops 1st version of RFID technology, an espionage tool for the soviet union. It was a covert listening device that used sound waves to manipulate a diaphragm to modify a reflected radio frequency. This early device did not use identification tags. 1945-1948 - IFF Transponder developed by the UK during WWII for use among the Allies. It was used by aircrafts to Identify targets as Friend or Foe, thus the acronym IFF. This device is still used today. 1948 - Harry Stockman publishes “Communication by Means of Reflected Power”, which set the pace for RFID research and development. 1973 - RFID as it exists today was developed by Mario Cardullo, and demonstrated by Steven Depp, Alfred Koelle, and Robert Freyman. The original patent used radio frequency, sound and light waves as transmission media. This device was used by the NY Port Authority as a toll device. The original device developed by Mario Cardullo was designed for use in the transportation, banking, security, and medical industries 1983 - First patent with the abbreviation RFID granted to Charles Walton. Currently, RFID is a major part of daily life, and used by the likes of the US Department of Defense, and Wal-Mart corporation
7. End History /Uses Finally, in 1973, RFID as it exists today was created. Mario Cardullo created a passive radio transponder with memory that was originally used by the New York Port authority as a toll device. The original patent used radio frequency, sound and light as transmission media. Automotive vehicle identification
10. Large use of RFID Today, the largest use of active RFID is the US Department of Defense. Over 1 million shipping containers that travel outside the continental states are tracked with active tags produced by Savi Technologies. The largest use of passive RFID is by Wal-Mart. With over 2,800 retail stores, the corporation employs over 25,000 reader systems.
