The NFC device is connected with external host equipment and comprises a microprocessor, an NFC controller, an antenna and a matching circuit, wherein the microprocessor comprises an interface, an NFC protocol stack module and an NFC management module; the host equipment is connected with the NFC device through the interface; the host equipment and the NFC device transmit interface instructions through the interface; the NFC protocol stack module is used for implementing NFC services; the NFC management module is used for resolving the interface instructions and controlling the NFC protocol stack module to execute the NFC services according to the interface instructions; the NFC controller is respectively connected with the microprocessor, the antenna and the matching circuit; the antenna and the matching circuit are used for performing near field communication with the external NFC equipment.

Description

technical field [0001] The present invention relates to the technical field of NFC (Near Field Communication, short distance wireless communication), in particular to an NFC device equipped with an NFC protocol stack. Background technique [0002] NFC technology is jointly developed by Philips and Sony. NFC is a non-contact identification and interconnection technology that enables short-range wireless communication between mobile devices, consumer electronics, computers and smart control tools. In order to promote the development and popularization of NFC, the industry has created a non-profit standard organization - NFC Forum, which is used to promote the implementation and standardization of NFC technology and ensure the collaboration between devices and services. [0003] With the development of short-range wireless communication technology, more and more mobile phones have supported the NFC function, and can operate in the three modes of reader-writer mode, point-to-po...
