The Radio Frequency Identification (RFID) tag is an electronic device that holds data. Typically these tags are attached to an item and contain a serial number or other data associated with that item. Due to development of Radio Frequency Identification (RFID) systems is rapidly growing and has the potential to affect many different field and applications. The researcher summarize major RFID applications, and present a primer on RFID fundamental principles. Finally, we discuss several challenges and obstacles to RFID adoption, as well as emerging technologies relevant to RFID. This paper describes the potential of Radio Frequency Identification technology in facilitating efficient library operations and demonstrates that RFID can be used in libraries to ensure security and facilitate innovative services and highlights key issues that need to be addressed in order to achieve successful implementation of RFID in Libraries and also examines key challenges in the deployment of the technology.
