RFID Journal Glossary

Passive
When used to refer to an RFID transponder, the term "passive" means a transponder has no power source and cannot actively broadcast a signal. A passive tag harvests energy emitted by a reader antenna, uses it to run the circuitry on an RFID chip and then reflects back a signal to the reader. Because the signal to the reader is reflected by the passive tag, the signal is weak and the read range of passive tags is thus relatively short.
