A multi frequency RFID (Radio Frequency IDentification) reader/writer system is capable of identify different tags which are operating at multi frequencies simultaneously. The unavailability of a dedicated read/writer for all RFID tags has created a bottleneck in expansion of the RFID market. The present system can be able to support most regularly used frequencies in the RFID world. The reader includes a radio frequency modulation and demodulation for each operating frequency of the tags and these modules are integrated and interfaced to microcontroller.
