Radio frequency identification use electromagnetic fields to automatically identify and track tags attached to books. There are several ways of identifying tags but the most common is to store a serial number. The chip and antenna attached together are called an RFID tag. The RFID reader or scanner converts the RFID tag information into digital information which will further seen in computer and stored for future use.

In Library Management system, RFID act as a systematic way of data collection. This system plays an important role in redefining the library process by scanning books on the shelves itself without tipping them out.
