随着通信技术的飞速发展，RF射频模块在生活中的应用越来越广泛，RF模块以特小体积更低成本实现高速数据传输的功能，可以一对一,也可以一对多传输，可以灵活的运用起来。

　　RF射频模块，对错触摸的自动辨认技能，其基本原理是使用射频信号和电磁的空间耦合、传播的传输特性，完成对被识物体的自动辨认，是一种归纳多学科、多技能的运用技能。无线IC卡，又称方便卡、雷达卡、感应卡、非触摸卡、RF卡、戏法卡、射频卡、聪明卡，它将无线射频辨认技能与IC卡技能有机结合起来，处理了无源(卡内无电源)和免触摸这一难题，是电子器件范畴的一大打破。

　　RF模块传输广泛地运用在车辆监控、遥控、遥测、小型无线网络、无线抄表、门禁系统、小区传呼、工业数据采集系统、无线标签、身份识别、非接触RF智能卡、小型无线数据终端、安全防火系统、无线遥控系统、生物信号采集、水文气象监控、机器人控制、无线232数据通信、无线485/422数据通信、数字音频、数字图像传输等领域中。
