PURPOSE: A transponder is provided to configure many RFID(Radio Frequency Identification) chips in the one transponder, thereby enabling the one transponder to exchange information with many readers. CONSTITUTION: Capacitors(60a,60b,60n) are connected to capacitors(62a) in parallel to have bigger resonant frequency values than a specific resonant frequency. A capacitor(60c) is connected to one of the capacitors(62a) in serial so as to have a smaller resonant frequency value than the specific resonant frequency. RFID chips(602a,602b,602c,.....602n) installed on a transponder react to all readers having the specific resonant frequency, and exchange information with all the reacted readers.
