近场通信（NFC）诞生于2002年，是使用13.56MHz RFID技术的一个专用子集。它最初用于访问控制/门禁和公共交通付费卡，由于与信用卡/借记卡和智能手机的集成，它发展迅速，不仅用于付费，还用于一直在线的无线连接如简化无线配对、诊断信息读取、设备参数的无线配置等等。
意法半导体作为RFID和NFC技术的先行者之一，提供了广泛的HF RFID/NFC产品，覆盖了所有NFC应用的需求，有丰富的生态系统支持。这些设备包括NFC / RFID标签、动态NFC标签、NFC / RFID读写器 & NFC控制器，包括用于安全NFC应用的安全组件和整套解决方案。
意法半导体非常荣幸成为NFC论坛的赞助成员。
