Abstract: This paper presents a secure voting system based on multilayered biometric authentication using embedded systems, IoT, and Python integration. The system employs three layers of identity verification—RFID card authentication, fingerprint recognition, and face detection through a USB camera—ensuring a high level of security and eliminating the chances of fraudulent voting. An Arduino Mega2560 serves as the central controller, with an LCD displaying status messages and a buzzer providing alerts when authentication fails. Push-button switches enable user inputs, while a NodeMCU module facilitates IoT-based monitoring for transparency and data storage. Only after successful authentication across all three layers can a voter cast their vote, thereby enhancing the integrity and reliability of the voting process.

Keywords: Biometric Authentication, RFID, Face Recognition, IoT Monitoring, Secure Voting.
