## 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.

The NFC module provides connected tag reading and writing.
