US 10,873,368 B1 · Near field communication device and information processing method

Abstract

Implementations of this specification provide a near field communication device and an information processing method performed by the near field communication device. An example device includes: an antenna; a radio frequency module connected to the antenna; a CPU circuit connected to the radio frequency module; and a power control module connected to the radio frequency module and the CPU circuit. The radio frequency module outputs, based on a radio frequency signal from the antenna, information conforming to a near field communication protocol of the radio frequency signal. The power control module controls the CPU circuit based on an indication included in the information, such that the CPU circuit is suppressed when a communication distance of the near field communication protocol of the radio frequency signal is greater than a predetermined threshold.
