This is a very useful application of RFID (Radio-Frequency IDentification) and is very commonly used in institutes, offices, homes and so on. An RFID system consists of a reader device and a transponder. A transponder or tag has a unique serial number which is identified by the reader. Here RFID has been interfaced with ARM processor to provide secured access. The relevant messages are also displayed on a 16x2 LCD. RFID automated access for door controls to buildings, departments, rooms, secured closets (wiring, PBX, etc.) and cabinets is very cost effective and secure to use.
