The entering of the codes isn't just to verify the child has the unit, but also to assist them in planning to get to school. (8PM code entry? Reminder to get stuff ready for the next school day.)
I don't think children skip school because they forget they have school the next day...
I can't see how the school can enforce this without parental cooperation.
Well, it's not. The system is opt-in by the parents of the truant students.
If my child were going truant a lot, I'd approve.
Personally, I still wouldn't. These problems are better solved by the parent than by the school administration.
