近场通信（Near Field Communication，简称NFC），是一种新兴的技术，使用了NFC技术的设备（例如移动电话）可以在彼此靠近的情况下进行数据交换，是由非接触式射频识别（RFID）及互连互通技术整合演变而来的，通过在单一芯片上集成感应式读卡器、感应式卡片和点对点通信的功能，利用移动终端实现移动支付、电子票务、门禁、移动身份识别、防伪等应用。近场通信技术是由诺基亚（Nokia）、飞利浦（Philips）和索尼（Sony）共同制定的标准 ，在ISO 18092、ECMA 340和ETSI TS 102 190框架下推动标准化，同时也兼容应用广泛的ISO 14443 、Type-A、ISO 15693、B以及Felica标准非接触式智能卡 的基础架构。
NDEF 全称 NFC data exchange format 即 nfc 数据交换格式，是一种标准化的数据格式，可用于在任何兼容的NFC设备与另一个NFC设备或标签之间交换信息。数据格式由NDEF消息和NDEF记录组成 。
