Many small private schools have the issue of alerting students when their parents have arrived to pick them up. On small campuses, this is disastrous because it creates traffic jams on roads and slows down staff, students and parents. Dismissrr solves this using QR codes on parking stickers that each parent puts on his or her car. A staff member scans the barcode using a iPhone. This makes the names of all that family's students show on the projector screen in his or her current classroom.
