  • Patent number: 9237508
    Abstract: A mobile terminal capable of determining whether a near field communication source is a mobile terminal or not, and capable of appropriately restricting information reading in near field communication. The mobile terminal includes an antenna for near field communication and an RF part. The RF part includes an electromotive force measuring part which measures the electromotive force of a carrier wave received by the antenna, a communication permission/prohibition determining part which, when the measured electromotive force is less than or equal to a predetermined threshold value, determines that the sender of the carrier wave is a mobile terminal and outputs a communication prohibition signal, and an RF controller which acquires the communication prohibition signal and locks the RF part.
