New Technologies have always been of interest for libraries, both for the potential of increasing the quality of service and for improving efficiency of operations. At present libraries of all kinds whether public, research or special libraries are overwhelmingly looking forward to adopt new technologies due to its potential for cost savings in the operations and the management of books and patrons. One such technology which is gaining tremendous popularity among the various libraries is RFID technology since it revolutionizes the way a library operates.
RFID (Radio Frequency Identification) allows an item, for example a library book, to be tracked and communicated with by radio waves. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.
