A transponder which contains a battery or other electrical energy source that provides the energy needed to transmit information and receive data.

• Antenna

A conductive element that enables the transponder to send and receive data. Passive, low- (135 kHz) and high-frequency (13.56 MHz) transponders usually have a coiled antenna that couples with the coiled antenna of the reader to form a magnetic field. UHF transponder antennas can have many different shapes. Readers also have antennas which are used to emit radio waves. The electromagnetic energy from the reader antenna is “harvested” by the transponder and used to power the microchip, which then transmits back its own signals.
