There are two types of RFID transponders: passive and active.  An active transponder has an internal battery, similar to the battery contained in a wristwatch.  When the battery is exhausted, the transponder is no longer usable.  A passive transponder has no internal battery.  Instead, the sensor broadcasts radio waves to the transponder, and the transponder converts the radio energy into electricity.  The electricity is collected in a [[capacitor]] until sufficient voltage is stored to power the microprocessor on the transponder.  Passive transponders have an indefinite lifespan.
