ABSTRACT
Introduction To RFID
RFID stands for radio frequency identification,a term that describes any system of identification wherein an electronic device that uses radio frequency or magnetic field variations to communicate is attached to an item.The components of RFID are the tag, which is the identification device is attached to an item to be tracked,and the reader , which is a device that can recognize the presence of RFId tags and read the information stored on them.The system with which the reader communicates usually runs a software that stands between readers and applications.This software is called RFID middleware.
RFID In Libraries
Among the many uses of RFID technology is its deployment in libraries. This technology has slowly begun to replace the traditional barcodes on library items .The RFID tag can contain identifying information, such as a book's title or material type, without having to be pointed to a separate database .The information is read by an RFID reader, which replaces the standard barcode reader commonly found at a library's circulation desk. It may replace or be added to the barcode, offering a different means of inventory management by the staff and self service by the borrowers. It can also act as a security device, taking the place of the more traditional electromagnetic security strip.
Advantage
RFID tags replace both the EM security strips and Barcode. They Simplify patron self check-out and check-in. They have the ability to handle material without exception for video and audio tapes. Radio Frequency anti-theft detection is innovative and safe. It has a High-speed inventory and it can identify items which are out of proper order. Last but not least it has Long-term development guarantee .
Disadvantage
The major disadvantage of RFID technology is its cost. It is possible to compromise an RFID system by wrapping the household foil to block the radio signal. It is also possible to compromise an RFID system by...
