ABSTRACT:
An information processing terminal is disclosed that is allowed to carry out contactless data transmission or reception with a reading or writing device by use of a magnetic field. The information processing terminal includes a data transmitter or receiver, a signal processor, and a load modulator. The data transmitter or receiver is configured to generate an induced voltage from a magnetic field generated from the reading or writing device at the time of data reception, and send a transmission signal to the read/write reading or writing device at the time of data transmission. The signal processor is configured to generate a response signal based on the induced voltage. The load modulator controls a variable resistance based on the induced voltage and carries out load modulation relating to the transmission signal based on the response signal and the variable resistance.
