Remote door lock
August Smart Lock: San Francisco designer Yves Behar of Fuseproject has designed a lock that replaces physical keys with a smartphone app. August Smart Lock is a cylindrical metal device that fits over the existing deadbolt and syncs with the user's smartphone. It uses Bluetooth to sense when the phone is approaching in your pocket then unlocks the door automatically, while remote allows you to open the door for guests from anywhere.
