Near field communication module, system and method thereof

Abstract

The present invention relates to a near field communication module, system and method. The near field communication method is as follows: both communication terminals use sound as an information carrier to establish a near field communication connection within a preset near field range, and then use sound channels or near field communication to establish a near field communication connection. Field wireless communication channel for data exchange. The near field communication system includes a master device and a slave device connected wirelessly, and both the master device and the slave device contain near field communication modules. The NFC system may also include a backend connected to the host device via wired or wireless means. The near field communication module includes a control unit and an audio communication sending unit and an audio communication receiving unit respectively connected to the control unit. The near field communication module, system and method provided by the present invention can enable the intelligent terminal to have a near field communication function without changing the existing intelligent terminal, and promote the promotion and application of near field communication.

Description

technical field [0001] The present invention relates to the communication field, in particular to a near-field communication method. Background technique [0002] With the popularization of smart terminals, there are more and more demands for using smart terminals to perform near-field communication. Currently, well-known near field communication solutions applied to smart terminals mainly include a radio frequency SIM (Subscriber Identification Module, Subscriber Identification Module) card solution and an NFC (Near Field Communication, near field communication) solution. The radio frequency SIM card solution adds the radio frequency communication function to the ordinary SIM card, so that the intelligent terminal inserted with the radio frequency SIM card can perform near-field communication with the terminal with the radio frequency SIM card reading and writing function. The NFC solution implements near-field communication between smart terminals by adding a near-field c...

AI Technical Summary

Problems solved by technology

At present, there are a huge amount of smart terminals and SIM cards on the market. Whether it is to replace the SIM card or transform the smart terminal, it will undoubtedly increase the cost of marketing and bring inconvenience to users, which will hinder the promotion of near-field communication applications.
