Title:
NEAR FIELD COMMUNICATION FRONT-END HARDWARE CIRCUIT, TERMINAL, READER/WRITER, SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/171723
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of communications. Provided are a near field communication front-end hardware circuit, terminal, reader/writer, system and method. The near field communication front-end hardware circuit comprises: a near field communication antenna, a wave detection unit and a communication interface pin unit; the near field communication antenna comprises a near field coil and a matching circuit, the frequency of the near field coil matches a selected carrier frequency; the wave detection unit is used for filtering out a carrier in a received modulation signal to obtain the original modulation signal, and the wave detection unit is connected to the near field coil; the communication interface pin unit is used for outputting the original modulation signal to a micro-control unit, and the communication interface pin unit is connected between the wave detection unit and the micro-control unit. The above-mentioned circuit enables power consumption to be significantly reduced.
