The invention provides a system for improving communication statuses among a sensor, a tag and a non-contact type IC card for RFID (Radio Frequency Identification). In the present system, a resonator is added to a sensor a tag, or non-contact type IC card. The resonator is constituted by a coil and a capacitor. Further a magnetic substance is attached to the coil of the resonator so as to intensify the magnetic field. |
