What Is a Transponder?

A transponder is short for: transmitter + responder

The word came into use around 1944. In basic terms a transponder is a miniaturized electronic chip that has what is called nonvolatile memory. Nonvolatile memory is the type of memory that does not need constant energy for retention. Along with that electronic chip is a set of windings, very fine wire coiled around a tube. These windings look similar to the windings you would find in an electric motor.

There are two basic types of transponders. The first are the Electric Coupled Transponder systems. Electric coupled transponder systems are not limited to small areas for transmission but can transmit messages or signals for different ranges of distance including several inches to miles, as used in Satellites and Airplanes. These systems require large amounts of constant electricity to operate.
