Abstract— This article proposes a safe and efficient way to track student attendance through QR codes. Both students and teachers have their own user interfaces within the system. Real-time participation tracking, monitoring the number of attendees, and observing student attendance history are all available through the teacher interface. The student user interface allows them to view their attendance for specific classes or subjects. Each student has a unique QR code that is refreshed every 30 seconds to prevent duplication or misuse. The attendance has to be marked within the five to eight minutes provided by scanning the QR code. For greater security, the QR code screenshots are disabled for preventing unauthorized sharing. Once scanned, the attendance gets automatically recorded, and teachers are able to see the list of present students in real-time and also download the CSV file which includes the details of students.

Keywords— Secure attendance system, student tracking, QR Code Attendance, Real-time attendance
