Abstract

The embodiment of the present invention provides an NFC communication device and method. The NFC communication device of the embodiment of the present invention first uses the first NFC antenna built in the mobile terminal to receive the NFC signal. The control unit determines whether the SIM card has the NFC function, and if so, sends The first control signal is sent to the first switch unit, and the first switch unit sends the NFC signal to the SIM card according to the first control signal, and the SIM card processes the NFC signal accordingly; this device can be implemented by using the NFC antenna built into the mobile terminal. The NFC communication function in the NFC‑SIM card solves the technical problem that mobile terminals with metal back shells will block the NFC antenna in the SIM card, allowing the mobile terminal to use the NFC function of the SIM card normally.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an NFC communication device and method. Background technique [0002] With the rapid development of mobile terminal devices, mobile payment has become one of the most popular applications in the radio frequency identification industry, such as NFC (Near Field Communication, near field communication) payment. NFC is a short-distance high-frequency wireless communication technology that works in the 13.56MHz frequency range. With the popularization of mobile consumer electronics products such as smart phones, NFC systems with low energy consumption and fast data transmission speed are used in mobile payment and electronic identity authentication. , Electronic tickets and other fields have been widely used. [0003] At present, the development trend of mobile phones is towards thinner and multi-functional development. As the thickness of the mobile phone is getting thinner, ...
