Multi-Accessible Combination & Key-fob Doorlock
Keys have been around a very long time now and so have numerical door locks, but this device takes security to a whole new level. This is essentially a normal door lock handle combined with a numerical door lock, allowing you to open it with either key, a code, an iButton or a combination of these. Multiple people can be given access by giving them different iButtons. You can also restrict access based on certain times of the day and it will even lock the door behind that forgetful person.
The iButton is basically a computer chip in a key-fob sized piece of plastic that allows you to swipe against a sensor in the lock. Finally, if you’re thinking this isn’t quite good enough for you, then consider this – the U.S. Mint actually uses iButtons.
