RFID 基础知识 

1．什么是 RFID 

  
RFID 是 Radio Frequency Identification 的缩写，即射频识别。常称为感应式电子晶片或近接卡、感应卡、
非接触卡、电子标签、电子条码，等等。  

一套完整 RFID 系统由 Reader 与 Transponder 两部份组成 ,其动作原理为由 Reader 发射一特定频率之无
限电波能量给 Transponder,用以驱动 Transponder 电路将內部之 ID Code 送出，

此时 Reader 便接收此 ID Code。

 

Transponder 的特殊在于免用电池、免接触、免刷卡故不怕脏污，且晶片密码为世界唯一无法复制，安全性高、

长寿命。  
RFID 的应用非常广泛，目前典型应用有动物晶片、汽车晶片防盜器、门禁管制、停车场管制、生产线自动化、
物料管理。RFID 标签有两种：有源标签和无源标签。

 2．什么是电子标签  
  
电子标签即为 RFID 有的称射频标签、射频识别。它是一种非接触式的自动识别技术，通过射频信号识别目标
