The QR-Based Entry System for Classrooms and Labs is designed to enhance security, automate attendance tracking, and streamline access management in educational institutions. By generating unique QR codes for students and faculty, the system ensures real-time authentication at entry points using mobile devices or dedicated scanners. Upon scanning, the system verifies credentials against a secure database, granting access only to authorized individuals while automatically recording attendance. This approach eliminates manual errors, proxy attendance, and unauthorized entry, improving efficiency and security. Integration with cloud storage, IoT-enabled smart locks, and encryption techniques ensures data privacy and scalability. The proposed system minimizes administrative workload, enhances institutional security, and fosters a technology-driven learning environment, making it a cost-effective and scalable solution for modern classrooms and laboratories.
