Proposed are a near field communication implementation method and system. The method includes: a sending device modulating a digital signal and playing a sound signal generated by modulation; and a receiving device sampling the sound signal and demodulating a sampling signal to obtain a digital signal. The present invention can realize near field communication among mobile communication devices without an embedded near field communication (NFC) chip, which solves the problem that the hardware requirements of the existing near field communication solution are high and the application range is narrow. |
