Apparatus for identifying each of a plurality of moving objects including an electromagnetic field generator for radiating over a given area an electromagnetic field having a predetermined frequency, a plurality of moving object identification signal generators, each adapted for mounting on one of the movable objects and an identification receiver for receiving signals generated by transmitter units in the moving object identification signal generators. The identification receiver generates an output signal having a code corresponding to the frequency of the transmitter unit whose signal is being received.
