Biometric Access Control Implementation Using 32 bit Arm Cortex Processor

This paper describes a fingerprint system for a secure perimeter, allowing access to only those people who are identified by the officials using bio-metric identification of finger print. The system would work in both online and offline mode. System also employs Power over Ethernet. The goal of this project is to develop a complete system for fingerprint identification. The fingerprint scanning device utilizes serial communication. This device will be connected to the microprocessor using RS-232 ports. The system will consist of an LM3S6965 microprocessor, LCD display, fingerprint sensor, electronic door strike, and MCU to USB PC interfacing. Software Code for the PC allows the owner to register and maintain the attendance record for finger-prints and monitor door entry. LCD's and LED's will be used to display whether or not access was granted or denied.
