There has been emerging demand for secure system that must be reliable and fast responding for the industries and company. RFID (Radio Frequency Identification) is one of the reliable and fast means of identifying any material object. Their significant advantages are that they can read wirelessly, contain more information than barcode and more robust in nature and based on non-line-of-sight technology. RFID tags can read in any environmental challenging conditions where other read technology likes barcode or optical card reader useless. RFID system provides an efficient and simple method for identification. There are other methods for identification like barcode, optical character recognition, biometric and smart card but possible area of use is much larger for RFID system. Like transportation and logistics, security and animal tagging, postal tracking, time and attendance and road toll management. RFID tags act as small transponders that respond to quires from a reader wirelessly and transmitting a serial number or similar identifier .
In this project we proposed a secure system that provides information about authorized and unauthorized persons. In this system when card brought near to the RFID module reads the card information and it compare with the data in the program memory and displays authorized or unauthorized entry. The door opens for authorized entry and does not give access for unauthorized. We are here using electromagnetic lock to show the access.
