Keypad and Fingerprint Sensor based 2-Step Security Project

Advanced 2-Step Security System with Keypad and Fingerprint Sensor

The Advanced 2-Step Security System combines a traditional keypad entry system with a modern biometric fingerprint sensor for an added layer of protection. This project allows you to control access to a room or device with both a password and a fingerprint scan. By requiring two types of verification, it significantly enhances security compared to standard systems. Ideal for personal use, science fairs, academic projects, and schools, this security system offers a perfect mix of innovation and practicality.
