passive 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. Passive RF tags obtain operating power generated from the RF reader. They are smaller and lighter than active tags but have a shorter communication range and require a high powered reader. Passive tags are generally read-only and as such, once it is programmed with data, that data cannot be modified.

The opposite of a passive tag is an active tag.
