Even the humble padlock is getting a "smart" upgrade, said John Brandon at Wired. A Utah firm called FÜZ Designs has unveiled a Bluetooth-enabled padlock called Noke (pronounced "no key") that can be opened using mobile devices like iPhones and Android phones. To open the $60 lock, just press on the lock's shackle, which triggers the device to search for a paired phone nearby and unlock. If your phone isn't available, don't worry: Noke, which comes in silver or black, also allows users to program the lock with a backup combination. And if the internal battery dies, a terminal on the lock's underside lets you plug in with a new battery for temporary power. "Much nicer than a bolt cutter, right?"
