Abstract: The objective of this project is to develop an RFID-based passport authentication system using ESP32 technology to improve security and automate identity verification. The system uses RFID tags/cards as digital passports and verifies them through an RFID reader module (RC522). The ESP32 microcontroller acts as the main controller and processes the RFID data. If the scanned RFID card matches the stored authorized UID, access is granted; otherwise, access is denied. The system displays authentication status on an LCD display and indicates the result using LEDs and a buzzer. This system reduces manual verification, increases security, and provides a fast and reliable authentication mechanism.
