Abstract

The invention provides an external near field communication (NFC) device which comprises an interface module, an antenna module, a NFC module and a control module, wherein the interface module is connected with an external terminal, the antenna module is connected with an external non-contact NFC device, the NFC module is used for receiving external data transmitted from the non-contact NFC device or sending data to the non-contact NFC device through the antenna module, the control module is used for receiving terminal data transmitted from the terminal through the interface module and sending the terminal data to the NFC module, or receiving external data transmitted from the NFC and sending the external data to the terminal, and thus the NFC between the terminal and the non-contact NFC device is accomplished. By means of the external NFC device, the terminal supports a NFC feature under the premise that the hardware of the terminal is not improved.

Description

technical field [0001] The invention relates to the technical field of short-distance wireless communication, in particular to an external near-field communication device. Background technique [0002] A near field communication (Near Field Communication, NFC) technology is developed from a radio frequency identification (Radio Frequency Identification, RFID) technology, and is used to realize information exchange between two short-distance devices. NFC-enabled terminals can be simulated as contactless cards, card readers or peer-to-peer communication nodes. [0003] If a terminal such as a mobile phone or a computer is to support NFC, it is usually necessary to build an NFC chip in the terminal, which requires hardware modification of the terminal, which is costly to implement. Contents of the invention [0004] In view of this, the present invention provides an external near-field communication device, which enables the terminal to support the NFC function without perfo...
