        abstract = {This paper presents the design and implementation of Bio-Ballot, a fingerprint-secured electronic voting system with real-time transparency. The system leverages biometric authentication using the R307 optical fingerprint sensor interfaced with an Arduino UNO microcontroller to ensure that each registered voter casts exactly one vote, strictly upholding the principle of one person, one vote. Votes are securely stored in the Arduino's internal EEPROM, ensuring data persistence even during sudden power failures. A 16×2 LCD provides live statistics including total votes, gender-based participation counts, and candidate-wise results. The system features a hybrid architecture, combining complete offline functionality for areas with limited connectivity and optional online monitoring through an ESP Wi-Fi module and Flask-based backend server. Testing confirmed a 0% False Accept Rate (FAR), 100% enrollment success rate, and seamless data synchronization between offline EEPROM storage and the online database. Bio-Ballot demonstrates a practical, cost-effective, and tamper-resistant solution for secure and transparent elections applicable to both local and large-scale deployments.},
