Locks are a fascinating piece of technology. They have existed for thousands of years, roughly as long as people have had something they thought someone would want to steal. Even the Great Pyramids at Gaza had simple locks on the entrances to the tombs. But locks have come quite a long way since then. Today locks can be small, large, wireless, or even digital. Go back a hundred years and the concept of being able to use a fingerprint as a key to a biometric lock would seem like an absurd fantasy by the insane. Yet there are locks that open according to voice patterns, palm scans, fingerprints, DNA, Bluetooth, RFID tags, and the list goes on. Locks are on everything, our homes, our rooms, our cars, our computers, and other items where valuables may be stored.
