This embedded system project implements a multi-factor authentication safe using an RFID/NFC tag reader (MFRC522), a fingerprint scanner (R307), and an optional IR remote sensor for PIN input, all controlled by an Arduino Uno and housed within a hand-built wooden enclosure. Upon powering up, the system waits for an RFID card scan; if the presented UID matches the authorized one stored in the firmware, it proceeds to fingerprint verification. The R307 module scans the finger and checks against registered templates, granting access only if a valid match is found with a confidence score above 100. Once both authentications are successful, a green LED connected to pin 7 blinks twice to indicate access granted. Additionally, the system includes pre-wired logic for triggering a 12V solenoid lock via an N-channel MOSFET, designed to unlock the safe door (functionality pending solenoid installation). Serial messages provide real-time status updates for verification and debugging. The system also contains functional code and wiring for a basic IR sensor input, which can be used as a third authentication layer in future iterations. This project showcases layered authentication, sensor interfacing, and hardware integration within a robust, scalable embedded system.
