Menu: Manage Attendance, then QR Student Attendance.

The heading is QR Attendance. Generate student ID card here opens the ID card page if a student has no code yet.

Allow the camera. The scanner shows Scanning, then Matched when a code is read. View sample here shows what a valid code looks like.

The student window offers Present, Absent, Late, and Half day. Click Confirm. A successful mark says the student attendance was marked.

Today's list shows status, name, class, date, whether the mark came from a QR code or was manual, and Delete. Delete asks you to confirm, then removes that mark for the day.

On this list, a status of 3 is shown as Holiday and any other value is shown as Half Day. The buttons you click still say Late and Half day. Check the status after you confirm if the badge does not match the button you chose.
