低頻段射(she)頻標(biao)簽(qian)(qian)，簡稱為(wei)低頻標(biao)簽(qian)(qian)，其(qi)工(gong)作(zuo)頻率(lv)范圍為(wei)30kHz～300kHz。典型(xing)工(gong)作(zuo)頻率(lv)有(you)125KHz和(he)133KHz。低頻標(biao)簽(qian)(qian)一(yi)般(ban)為(wei)無源標(biao)簽(qian)(qian)，其(qi)工(gong)作(zuo)能量通過電(dian)感耦合方式(shi)從閱(yue)讀(du)器(qi)(qi)耦合線(xian)圈的(de)輻(fu)射(she)近場(chang)中獲得。低頻標(biao)簽(qian)(qian)與閱(yue)讀(du)器(qi)(qi)之間傳送數(shu)據時，低頻標(biao)簽(qian)(qian)需位于閱(yue)讀(du)器(qi)(qi)天線(xian)輻(fu)射(she)的(de)近場(chang)區內。低頻標(biao)簽(qian)(qian)的(de)閱(yue)讀(du)距離一(yi)般(ban)情(qing)況下小于1米。低頻標(biao)簽(qian)(qian)的(de)典型(xing)應用有(you)：動(dong)物識(shi)別(bie)、容器(qi)(qi)識(shi)別(bie)、工(gong)具識(shi)別(bie)、電(dian)子閉鎖防盜（帶有(you)內置應答器(qi)(qi)的(de)汽車鑰匙）等。
中(zhong)(zhong)高(gao)頻(pin)(pin)(pin)段(duan)(duan)射頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)的(de)(de)工(gong)(gong)作頻(pin)(pin)(pin)率一(yi)般(ban)(ban)為(wei)(wei)(wei)3MHz～30MHz。典型工(gong)(gong)作頻(pin)(pin)(pin)率為(wei)(wei)(wei)13.56MHz。該頻(pin)(pin)(pin)段(duan)(duan)的(de)(de)射頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)，因其工(gong)(gong)作原理(li)與(yu)低(di)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)完全相同，即采(cai)用電(dian)感(gan)耦(ou)合方(fang)式(shi)工(gong)(gong)作，所以宜將其歸為(wei)(wei)(wei)低(di)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)類(lei)中(zhong)(zhong)。另一(yi)方(fang)面，根據無(wu)線(xian)電(dian)頻(pin)(pin)(pin)率的(de)(de)一(yi)般(ban)(ban)劃分，其工(gong)(gong)作頻(pin)(pin)(pin)段(duan)(duan)又(you)稱為(wei)(wei)(wei)高(gao)頻(pin)(pin)(pin)，所以也常將其稱為(wei)(wei)(wei)高(gao)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)。鑒于(yu)該頻(pin)(pin)(pin)段(duan)(duan)的(de)(de)射頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)可能是(shi)實際應(ying)用中(zhong)(zhong)最(zui)大量的(de)(de)一(yi)種射頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)，因而(er)我(wo)們(men)只要將高(gao)、低(di)理(li)解成(cheng)為(wei)(wei)(wei)一(yi)個相對的(de)(de)概念(nian)，即不會造成(cheng)理(li)解上的(de)(de)混亂(luan)。為(wei)(wei)(wei)了便于(yu)敘述，我(wo)們(men)將其稱為(wei)(wei)(wei)中(zhong)(zhong)頻(pin)(pin)(pin)射頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)。中(zhong)(zhong)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)一(yi)般(ban)(ban)也采(cai)用無(wu)源設主，其工(gong)(gong)作能量同低(di)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)一(yi)樣，也是(shi)通過電(dian)感(gan)（磁）耦(ou)合方(fang)式(shi)從閱(yue)讀(du)器耦(ou)合線(xian)圈的(de)(de)輻(fu)射近場(chang)中(zhong)(zhong)獲得。標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)與(yu)閱(yue)讀(du)器進行(xing)數據交換(huan)時，標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)必須位于(yu)閱(yue)讀(du)器天線(xian)輻(fu)射的(de)(de)近場(chang)區(qu)內。中(zhong)(zhong)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)的(de)(de)閱(yue)讀(du)距離一(yi)般(ban)(ban)情況下也小于(yu)1米(mi)。中(zhong)(zhong)頻(pin)(pin)(pin)標(biao)(biao)(biao)簽(qian)(qian)(qian)(qian)(qian)由(you)于(yu)可方(fang)便地做成(cheng)卡狀(zhuang)，廣泛應(ying)用于(yu)電(dian)子(zi)車票、電(dian)子(zi)身份證、電(dian)子(zi)閉鎖防盜（電(dian)子(zi)遙控門(men)鎖控制器）、小區(qu)物業(ye)管理(li)、大廈門(men)禁系統等。
超高頻(pin)與(yu)微波(bo)頻(pin)段的(de)(de)(de)(de)射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)簡稱為微波(bo)射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)，其(qi)典(dian)型工作頻(pin)率有433.92MHz、862(902)MHz～928MHz、2.45GHz、5.8GHz。微波(bo)射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)可分為有源(yuan)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)與(yu)無源(yuan)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)兩(liang)類。工作時(shi)，射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)位(wei)于(yu)閱(yue)讀(du)(du)器天線(xian)(xian)輻射(she)(she)場(chang)的(de)(de)(de)(de)遠(yuan)區場(chang)內，標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)與(yu)閱(yue)讀(du)(du)器之間的(de)(de)(de)(de)耦合方式為電磁耦合方式。閱(yue)讀(du)(du)器天線(xian)(xian)輻射(she)(she)場(chang)為無源(yuan)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)提供射(she)(she)頻(pin)能(neng)(neng)量，將(jiang)有源(yuan)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)喚(huan)醒(xing)。相應的(de)(de)(de)(de)射(she)(she)頻(pin)識別系(xi)(xi)統(tong)閱(yue)讀(du)(du)距離(li)一般(ban)大于(yu)1m，典(dian)型情況為4m～6m，最大可達10m以上(shang)。閱(yue)讀(du)(du)器天線(xian)(xian)一般(ban)均為定向天線(xian)(xian)，只有在(zai)閱(yue)讀(du)(du)器天線(xian)(xian)定向波(bo)束范圍內的(de)(de)(de)(de)射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)可被讀(du)(du)/寫(xie)。由于(yu)閱(yue)讀(du)(du)距離(li)的(de)(de)(de)(de)增加，應用中有可能(neng)(neng)在(zai)閱(yue)讀(du)(du)區域中同(tong)時(shi)出(chu)現多個(ge)射(she)(she)頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)的(de)(de)(de)(de)情況，從而提出(chu)了多標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)同(tong)時(shi)讀(du)(du)取的(de)(de)(de)(de)需(xu)求。目前(qian)，先進的(de)(de)(de)(de)射(she)(she)頻(pin)識別系(xi)(xi)統(tong)均將(jiang)多標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)識讀(du)(du)問題作為系(xi)(xi)統(tong)的(de)(de)(de)(de)一個(ge)重要特征。超高頻(pin)標(biao)(biao)(biao)(biao)簽(qian)(qian)(qian)主要用于(yu)鐵(tie)路車輛自動識別、集裝箱識別，還(huan)可用于(yu)公路車輛識別與(yu)自動收費系(xi)(xi)統(tong)中。
