I would never trust campus police with that access data. Police officers are under-educated, often predjudiced, and operate under a shield of un-prosecutability that makes them rouge agents. Further, on college campuses, students frequently are employed within campus police/public safety in ways that would make it very easy for them to grab the data.

Were that system implemented (which it should never be, because I thought of it in 10 seconds for a hacker news comment and anything real would need to be much more thought out), the list of card IDs should exist only on paper, in a locked file cabinet, controlled by someone whose job it is specifically to safeguard the privacy of students. Maybe the existing roles that manage grade privacy.

IT is even worse. I'd hate for a creepy sysadmin intern I declined to go on a date with to know where I lived or if I was alone in an academic building at night.
