"...no one knew how easy it was to read and duplicate information..."
Back in the late 80's, a certain technical university about 15 miles to the northwest of Charing Cross used perforated plastic cards for its halls-of-residence door security. One had to pay a silly amount in deposit for them, and they inevitably fractured at least once per term. It was, however, entirely possible to back-up* the the necessary information using a suitably sized drillbit and one of the billion or so phonecards that paved the streets in that Thatcherite wonderland...
(*for personal archive use only, and definitely not for mass duplication to allow assorted non-students to enjoy the facilities. That would have been bad)
