What does RFID mean? RFID stands for “radio frequency identification” and refers to a contactless identification method in which data is exchanged wirelessly between a transponder and a reader. The method was already used in the military sector in 1940 and was later further developed for contactless identification.
An identification medium, also known as a transponder, contains a microchip on which information such as a serial number is stored. The microchip is connected to an antenna that enables wireless communication with an RFID reader. Identification media are available in various form factors, for example as an RFID card or key fob.
