The three types of transponders are passive, semi-passive (or semi-active), and active transponders. Passive transponders do not have their own power source and rely on energy from the reader, while semi-passive transponders have a battery to power their circuitry but use the reader's signal to communicate. Active transponders have their own power source and can transmit signals over longer distances.
