Exam Hall Authentication Using Arduino Board

In the current era of digital transformation, ensuring secure and efficient authentication in academic environments is critical to maintaining integrity and preventing unauthorized access. This paper presents a low-cost, Arduino-based authentication system designed specifically for exam halls. The system utilizes RFID technology to verify the identity of students, granting access only to authorized individuals. Upon scanning their RFID cards, student data is authenticated against a preloaded database, and successful verification triggers access mechanisms such as unlocking doors or marking attendance. This solution enhances security, reduces manual intervention, and ensures smooth entry management during examination sessions. The system is scalable, reliable, and suitable for integration into educational institutions seeking to adopt smart, automated authentication processes.
