This research presents a Quick Response (QR) code-based student attendance system that generates unique QR codes for each class session in Computer Science Department, Nnamdi Azikiwe University. Traditional attendance tracking methods can be time-consuming and prone to errors, disrupting the learning environment. The system addressed these challenges by allowing students to scan QR codes upon entering the classroom using their smartphones, facilitating quick and accurate attendance recording. Agile methodology was used throughout the development process, enabling iterative progress and adaptability to changing requirements.
