When I was in college SSNs were still used as our ID numbers. Every dept had folders in the hall outside the office for each student. They'd put grades out in those folders. Guess what was printed on those grades.
If you had a mag stripe writer you could grab a random person's grades, encode their SSN on a student ID, and then use the card to buy stuff on campus.
