active tag
Last modified: Wednesday, March 09, 2005 

In an RFID system the transponder which contains the data to be transmitted is called an RF tag. Active tags have an internal battery to power them and are usually RW (tag data can be rewritten and/or modified). Active tags generally can transmit their data over a longer distance, the tag itself is larger than a passive tag, and has a limited operational lifespan.

The opposite of an active tag is a passive tag.
