Abstract

Identification of persons is essential at places like government and corporate organizations, airports, railway stations and banks. Auto-identification means automatic identification of entities. We have various methods for auto-identification. Some of them are barcode systems, optical character recognition, biometrics, smart cards and RFIDs. Out of these RFID technology is widely used. Radio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 2 inches away. The RFID Card Readers can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics navigation, inventory tracking, payment systems, and car immobilization. The RFID card reader read the RFID tag in range and outputs unique identification code of the tag at baud rate of 9600. The data from RFID reader can be interfaced to be read by microcontroller or PC. In this project, the RFID module reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna).This module isinterfaced with the micro controller and when the card is brought near to the RFID module, it reads the data in the card and displays on the LCD. If the data in the card is matched with the data stored in the program memory, then it compares and displays authorized message. If the data is not matched it displays unauthorized. For authorized message, the door will be opened and closes automatically after a small delay. If it is an unauthorized person it alerts the persons through a buzzer. The RFID module alerts the buzzer whenever it reads the data from the RFID card. The door will drive by DC gear motor by l293d driver. The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. This project can provide security for the industries, companies, etc. In this project 7805 is a regulator and it avoids noise spikes in power supply. RFID modem is connected microcontroller through serial port. These RFID modem works under 9600 or 4800 baud rates. 16X2 LCD connected to microcontroller through digital I/O lines.
