The Barcode scanner is interfaced with the micro controller and when the barcode card is brought to the sight of the scanner, it reads the data on the barcode card and displays on the LCD. If the data of the card is matched with the data 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 gets opened and the person gets in. after sometime the door gets closed (A relay will be energized). If it is an unauthorized person it alerts the persons through a buzzer..
