Definition Edit

An active tag is an RFID tag that relies on a battery for power.[1]

Overview Edit

The battery is used to communicate to the RFID reader, to power on-board circuitry, and to perform other functions. Active tags can communicate over greater distance than other types of RFID tags, but they have a finite battery life and are generally larger and more expensive. Since these RFID tags have an internal power supply, they can respond to lower power signals than passive tags.
