Enhanced Biometric Security System for Banking Using Arduino-Based Fingerprint Authentication

This work undertakes biometric authentication as its main objective to strengthen user security measures. The application of sophisticated technological solutions enables the construction of very secure spaces needed for banking because security requirements are exceptionally high. An R307s fingerprint module connects with Arduino Uno to operate a relay which controls system operations. The fingerprint module operates on Arduino Uno through predefined code to execute both fingerprint registration and verification operations. The Arduino Uno functions as the main component of the system. System activation happens only after a registered fingerprint detection or else it stays locked. The system brings a secure locking technology that banks specifically need.
