Near field communication module, system and method thereof

Abstract

The invention relates to a near field communication module, a system and a method thereof. The near field communication method comprises the following step that: both sides of a communication terminal take sound as an information carrier to establish near field communication connection in a preset near field scope, and then carry out data exchanges through a sound channel or a near field radio communication channel. The near field communication system comprises a master device and a slave device which are connected through a wireless mode. The master device and the slave device both comprise the near field communication module. The near field communication system also comprises a background which is connected with the master device through a wired mode or the wireless mode. The near field communication module comprises a control unit, a sound communication sending unit and a sound communication receiving unit, wherein the sound communication sending unit and the sound communication receiving unit are connected with the control unit respectively. By using the near field communication module, the system and the method provided in the invention, under the condition that the current intelligent terminal is not changed, the intelligent terminal possesses a near field communication function and application and dissemination of the near field communication are promoted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a near-field communication module, system and 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 ad...

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.
