RFID无线射频技术简介

射频识别（Radio Frequency Identification简称RFID）技术是20世纪90年代兴起的自动识别技术。它是一项利用射频信号通过空间耦合（交变磁场或电磁场）实现信息传递并通过所传递的信息达到自动识别的技术。与传统的接触式识别技术和光学识别技术相比，射频识别技术不但可以使电子标签和读卡器之间实现无接触．而且可以实现多个标签的防冲突操作，从而可以解决很多传统识别技术的缺陷。

RFID Wireless Radio Frequency Technology Synopsis

The radio frequency recognition （Radio Frequency Identification is called RFID） the technology is the automatic diagnosis technology which the 90s emerges. It is one item （alternating magnetic field or electromagnetic field） realizes the information transmission and through the information which transmits using the radio-frequency signal through the space coupling achieves the automatic diagnosis the technology. Compares with the traditional contact recognition technology and the optical recognition technology, not only the radio frequency recognition technology may cause the electronic tag and read between the card to realize without the contact, moreover may realize many label＇s against conflict operations, thus may solve many traditional recognition technology flaw.
