Active tags have a battery on the tag. The battery may be used to boost read/write range, allow for larger memories, or add sensory and data logging capabilities, such as temperature sensing. Passive tags receive all of their energy from the read/write device that "powers" the tag to allow it to transmit data.
RFID stands for Radio Frequency IDentification. A powered RFID has its own power or is powered by whatever its in (something like a car remote). a non-powered RFID gets its power from an outside RF, usually the device thats scanning the RFID (that microchip between your dogs shoulders that gives the vet a number to look up in the master data base for dog catchers so they can contact the original owners).
Comments on What is the difference between powered and non-powered RFID chips?
