Advantages and disadvantages of active RFID tags | Oprfid.com

An active RFID tag is one in which battery power is used to supply power to the electronics. This enables greater distances to be achieved as the tag is not dependent upon the received power to provide a reflected signal, and the control and processing circuits can be more sophisticated as in the case of the...

RFID Tags: Active, Semi-passive, and Passive - Barcoding, Inc.

There are three basic types of RFID tags; active, semi-passive, and passive. Active and semi-passive tags use internal batteries in order to power their internal circuits. Active tags also use their battery to send radio waves to a RFID reader, whereas semi-passive tags rely on the reader to supply power for its broadcasting. Both active and semi-passive tags are most commonly used for large-scale applications that need to be read over greater distances. Because of this, they typically broadcast high frequencies from 850 to 950 MHz and can be read from over 100 feet away.
