Startup Idea: Student Attendance Tracking Software

Startup idea to develop a software that accurately monitors student attendance and recording arrival times. The software should also keep track of absences and late arrivals.

I work in education. The big pain that is not yet solved by software is keeping track of student attendance.

We are doing it by hand because students are showing up at 11am sometimes 12pm. I would pay for software to solve this, I think a software that could track arrival times along with absences would be great.
