More Information
Summary:Disclosed is a system for electromagnetic interrogation of RFID transponders including at least one RFID terminal configured to emit an interrogation signal at a frequency F1, at least one RFID device referred to as repeater configured to receive the interrogation signal with frequency F1 and to repeat same towards at least one RFID transponder at the frequency F2, characterized in that the at least one RFID terminal includes at least one RFID reader configured to emit an interrogation signal with frequency F0 and at least one add-on RFID device configured to perform a frequency transposition from the frequency F0 to the frequency F1, the frequencies F0 and F1 being different.
