Here's the lock of the future.
This Chinavision facial recognition door lock is packing a couple of night vision cameras, using accurate 3D tech to recognize your face in a fraction of a second. It's designed to store up to 500 faces, functioning as an electronic time clock for businesses.
If you are a business owner, this techno-tattletale could come in handy, recording exactly who's coming and going and at what hours. But we'd rather use it at home, gazing into its twin cameras for less than a second as it pops open the door.
Couple this with keyless entry for cars, and the humble key will be a thing of the past. Maybe computers could be routinely equipped with this tech, too, so we would no longer need passwords.
