Electronic Biometric Voting Machine Using Arduino And IOT

Abstract

India represents a vast democratic system where elections play a critical role in governance. Voters participate in this process using Electronic Voting Machines (EVMs) installed at polling center. Despite their widespread use, occasional technical issues and the possibility of electoral manipulation can make the process challenging for authorities. To address these concerns, modern electronic voting technologies are being developed to ensure greater accuracy and minimize fraudulent practices. This work proposes a biometric-based voting mechanism utilizing an R307 Fingerprint Module interfaced with an Arduino Uno. The system records and stores each voter’s fingerprint in a secure database. A dedicated algorithm verifies the uniqueness of each entry, preventing duplication. During the voting phase, users must authenticate themselves by scanning their fingerprint. Access is granted only when the scanned data matches the stored template; otherwise, an alert is triggered using a buzzer. The integration of biometric verification strengthens system security and improves transparency. It streamlines the authentication process and effectively prevents impersonation, resulting in a more dependable and efficient voting system.
