新技术的出现充分发挥了物联网 (IoT) 的潜力。NFC（近场通信）技术以便捷且经济高效的方式实现连接，有助于最大限度地提升智能设备的整体体验。
什么是NFC技术？
NFC技术使用工作频率为13.56 MHz的射频链路，在读卡器和标签之间建立射频连接。为确保安全，通信范围通常限制在几厘米之内。
大多数情况下，NFC标签是一种无需电池的小型芯片，可以放置在实物内部或实物上。NFC标签可存储信息。当读卡器靠近标签时，它就能读取芯片中存储的信息，并执行各种任务。
读卡器位于主机内，通过磁场 (13.56 MHz) 为标签供电。与智能手机中的NFC控制器一样，NFC读卡器也可以作为标签使用，为多种用例提供支持：
- 现在，每个人都可以使用这项技术：
- 目前超过70%的智能手机支持NFC
- 移动无线技术使用的年复合增长率最快，达到8%
该生态系统已嵌入到数百万台设备中，可简化任何NFC项目。此外，作为一个促进新应用和合规性的行业联盟，NFC Forum已将NFC技术标准化。
NFC技术采用“一触即付”方法，只需在支持NFC的设备上轻轻一碰，用户就可以访问参数设置、防伪、安全支付、访问控制、消费者互动、配件识别等多种用例。
