An interrogator for use with a plurality of identification systems using different frequencies and different methods of demodulation and decoding is provided. Each of the identification systems includes at least one transponder adapted to attached to an article to be identified and each transponder includes an antenna for receiving an interrogation signal from the interrogator and for responding to the received interrogation signal with a responsive signal. The responsive signal includes at least an identification portion. The interrogator includes an antenna assembly for transmitting the interrogation signal from the interrogator to the transponder and receiving the responsive signal from the transponders. A processor is provided for processing the responsive signal received by the antenna assembly and creating an output signal substantially corresponding to the identification portion of the responsive signal. A display is provided for displaying the output signal. A programmable version of the interrogator is also provided as well as a method of using the interrogator to read a plurality of identification systems.
