Radio Frequency Identification System BE make use of RF energy to deliver data,belong to a wireless communication technique,is 1 kind not the system of contact type,it constitutes the component contain the application system of the reader,electron label,Antenna,host computer, its induction method depends on passive type Tag with active type Tag distinguish analyse, can be divided into induction coupling and back scattering coupling and induced the coupling is the induction method (as 135 KHzs、13.56 MHzs) which belongs to low frequency、high frequency,the back scattering coupling is the induction method(as 915 MHzs、2.45 GHzs) which belongs to superhigh frequency,microwave, and what we construct apply system is use the high frequency 13.56 MHzs of induction coupling method.

中文摘要无线射频辨识系统(Radio Frequency Identification；RFID)是利用RF能量来传递资料，属於无线通讯技术，是一种非接触式的系统，其组成元件有读卡机、电子标签、天线、主电脑应用系统，其感应方式依被动式Tag和主动式Tag来区分，可分为感应耦合和反向散射耦合而感应耦合是属於低频、高频的感应方式(如135KHz、13.56MHz)，反向散射耦合是属於超高频、微波的感应方式(如915MHz、2.45GHz)，而我们所建构的应用系统是使用高频13.56MHz的感应耦合方式。
