doc.: IEEE f Submission May 2009 IEEE f Working Document Active RFID Tag Definition An Active RFID tag is a device, typically attached to an asset or person, with a unique identification and the ability to produce its own radio signal not derived from an external radio signal. Active RFID tag applications include wireless sensor telemetry, control, and location determination. To generate a radio signal, Active RFID tags must employ some source of energy. Traditionally this has been accomplished by integrated batteries, although designs exist for such devices that harvest ambient energy from the surrounding environment.
