## Introduction<a name="section13587125816351"></a>

Near-field communication \(NFC\) is a non-contact identification and interconnection technology for short-distance wireless communication between mobile devices, consumer electronic products, PCs, and smart devices.

NFC service provides NFC switch control, NFC tag discovery and dispatch, NFC tag reading and writing, NFC card emulation functions.
