Have Aeries have a window where each school site can check in students upon late arrival or early check out.
Student would scan their id into the system using a barcode scanner that would capture their STU ID.
Then a window would pop up asking for reason for Tardy.
That would update their attendance record with code and reason and the attendance clerk could just verify.
Tardies can be scanned into the system now on the Attendance Management page. Here is more information: https://support.aeries.com/support/solutions/articles/14000093306-attendance-management
