  • DN381 RFID接收器的基帶電路

      Radio Frequency Identifi cation (RFID) technology usesradiated and refl ected RF power to identify and track avariety of objects. A typical RFID system consists of areader and a transponder (or tag). An RFID reader containsan RF transmitter, one or more antennas and an RFreceiver. An RFID tag is simply an uniquely identifi ed ICwith an antenna.

  • Digital+Signal+Processing+for+RFID

    Identification is pervasive nowadays in daily life due to many complicated activities such as bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data and procedures and target identification. This kind of task can be realized by passwords, bio- metric data such as fingerprints, barcode, optical character recognition, smart cards and radar. Radiofrequencyidentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems. It is a contactless, usually short distance, wireless data transmission and reception technique for identification of objects. An RFID system consists of two components: the tag (also called transponder) and the reader (also called interrogator).

  • RFID及倉儲管理系統

    一、RFID簡介1.1RFID概念RFID是Radio Frequency ldentification的縮寫,即射頻識別,常稱為感應式電子晶片或近接卡、感應卡、非接觸卡、電子標簽、電子條碼,等等。RFID技術是一種非接觸式的自動識別技術,它通過射頻信號自動識別目標對象并獲取相關數據,識別工作無須人工干預,可工作于各種惡劣環境。RFID技術可識別高速運動物體并可同時識別多個標簽,操作快捷方便。一套完整RFID系統由Reader與transponder兩部份組成,其動作原理為由Reader發射一特定頻率之無限電波能量給transponder,用以驅動transponder電路將內部之IDCode送出,此時Reader便接收此IDCode。transponder的特殊在于免用電池、免接觸、免刷卡故不怕臟污,且晶片密碼為世界唯一無法復制,安全性高、長壽命。RFID的應用非常廣泛,目前典型應用有動物晶片、汽車晶片防盜器、門禁管制、停車場管制、生產線自動化、物料管理。RFID標簽有兩種:有源標簽和無源標簽。
