This was suggested in 2017...Parents often select the wrong button when signing a child in or out. Instead of having two buttons it would be nice if there was just one button which would say "Drop Off" when the child is not present and "Pick Up" if the child has already been dropped off.

In my state parents must sign their child into the classroom. Since parent sign in is the only record we can use for attendance we consistently have to check attendance for parent errors.
