RFID based multipurpose system

Abstract

Radio Frequency Identification (RFID) is a technology in which communication takes place between a transponder and RFID scanner by means of radio waves. A transponder has a unique code saved in it which is used to identify the item that is tagged. The transponder is powered up when it comes into the vicinity of the scanner and sends a unique identification code to the reader by backscattering the received signal. This code is recognized by the RFID reader and is sent to the host system for retrieving the required information. RFID has a wide range of applications. The project is the implementation of two major applications of RFID namely Library Management and Parking Management. Automatic issue and return of books as well as protection against theft are the main objectives of Library Management System while authorization and secure entry of personnel and vehicles is a part of Parking Management System. This technology is widely deployed around the world but in Pakistan, it is not that common mainly because of the fact that it is very expensive and less awareness among the masses. The biggest aim of this project was to design a low cost commercial system.
