The system utilizes an ESP32-WROOM-32 microcontroller and communicates with the Firebase Realtime Database to store and transmit data. It provides real-time user feedback through Telegram notifications, web interface messages, and LCD display prompts. Access is granted when both the fingerprint and password are verified within the allowed number of attempts; otherwise, access is denied. The system was simulated using Proteus and programmed in C++ via the Arduino IDE. Future improvements may include the integration of multimodal biometric authentication to enhance security and system reliability.Access Control SystemBiometrics, Embedded SystemsESP32-WROOM-32Thesis
