RFID invented
Long-range RFID launched
RFID has its roots in the radar technology that emerged during World War Two, which was used by the British, American and German military to identify whether aircraft were friends or foe.
Sweden-born scientist and inventor Harry Stockman is credited with the invention of RFID. In 1940, Stockman moved to the United States and, in 1947, began experimenting with communication via passive reflected carrier waves – one application being a ‘Number Identification System’ that was a rudimentary form of RFID.
Long-range RFID tags – which are ‘active’ instead of ‘passive’ – have a range of up to 100 metres and are designed with low-power consumption to give longer battery life. Long-range RFID tags enable the user to track assets across large areas and spaces.
