ABSTRACT:
An electronic circuit for a contactless tag includes a rectification circuit that rectifies an induced electromotive force caused by bringing an antenna coil into close proximity to a reader/writer to generate a rectified voltage and a secondary battery. A charging/discharging circuit is provided that charges according to the rectified voltage and discharges the secondary battery.
