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...
