Abstract: Ensuring a fair and secure voting process is vital in today’s digital democracy. Conventional systems unauthorized voting, duplicate entries, and identity fraud. The proposed system, titled Trust Vote, addresses these challenges by implementing a three-stage identity verification process using RFID tags, face recognition, and fingerprint scans. Each voter is authenticated using all three methods before access is granted to.

The system architecture is NodeMCU ESP8266 microcontroller, which facilitates real-time communication with a central SQL database where voter records and biometric details are securely stored. In cases of failed verification or repeated attempts, a buzzer provides immediate alerts, ensuring compliance with the principle of "One Voter, One Vote." At the end of the process, the system automatically counts and displays valid votes. By combining hardware-level security with software automation, this project delivers a scalable and tamper-resistant voting platform designed to strengthen the credibility of electoral systems.
