PROBLEM TO BE SOLVED: To provide an RFID mobile terminal which offers a plurality of RFID functions and stable communication with a small-scale circuit.SOLUTION: An RFID mobile terminal includes first and second antennae, a first capacitor constituting a first resonance circuit together with the first antenna, and a second capacitor constituting a second resonance circuit together with the second antenna. The RFID mobile terminal also includes first and second switches provided in the first and second resonance circuits, respectively, first and second diodes whose anodes are connected to the first and second resonance circuits, respectively, and a receiver circuit connected with cathodes of the first and second diodes. A controller controls the first and second switches such that the first switch is on and the second switch is off when receiving with the first antenna, and the first switch is off and the second switch is on when receiving with the second antenna. |
