Keycard lock: Overview, Privacy & Types of card readers

A keycard lock is a lock operated by a keycard, a flat, rectangular plastic card. The card typically, but not always, has identical dimensions to that of a credit card, that is ID-1 format. The card stores a physical or digital pattern that the door mechanism accepts before disengaging the lock. Tor Sørnes was credited with the invention in the 1970s.
