Transponders were originally electronic circuits that were attached to some item whose position or presence was to be determined. The transponder operated by responding to a request received from an interrogator, either by returning some data from the transponder, such as an identity code, or returning the original properties of the signal received from the interrogator with a minimum time delay. Because the interrogator signal is much stronger than the returned signal, the former would swamp the latter unless some characteristic of the response were different. This difference can usually be achieved by separating the interrogation and response temporally or by changing the frequency. It is also possible to encode the response with some form of spread-spectrum modulation that can be decoded by the receiver.
