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.

In contrast, passive RFID tags rely solely on the...
