In 1945 Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with 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, not an identification tag, it is considered a predecessor of RFID technology.

What does RFID stands for?

RFID (radio-frequency identification) is a technology that uses radio waves to communicate between devices. RFID tags or chips are attached to objects, and RFID readers can send and receive signals from these tags. This allows for identification, tracking, and data transfer between the tagged objects and the reader. RFID is commonly used in applications such as supply chain management, asset tracking, and electronic payment systems.


What is the RFID?

Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
