Design and Construction of Secure Gate Access Control and Monitoring System Using RFID and Fingerprint Technologies

Abstract

The demand for security systems has greatly increased in recent years due to improved technology and the sophistication of criminally minded people. Security systems used for granting access have also evolved through the years in terms of technology and complexity. Biometric technology has been used to authenticate and grant access to people just like the case when using wireless technology like Radio Frequency Identification (RFID) technology. This project work was able to combine both RFID and fingerprint scanning to authenticate users and grant access to them through the gates. The system has a pedestrian gate and a vehicular entrance/exit gate. A known pedestrian activates the system via a button and then scans his/her finger. The system will check for a match and if found, the system allows the user to select the gate that will automatically open and close once the pedestrian enters.  For vehicles, the RFID tags were installed in the vehicles. Once a tag is within range, the system checks the ID of the tag and if a match is found, the main gate will open to allow access else access will not be granted. Finally, any unknown user will activate the system but someone in the building will be able to see the unknown user via the video feed which allows the capture of images in VGA format (640x480) and after which he/she will press an appropriate button to open either gate if need be. The system uses cheap but reliable modules and components to ensure quality at a low cost and minimize production time.
