Locks always struck me as the perfect application for Bluetooth LE: walk up to the lock, it detects the phone in your pocket or bag, checks the code and unlocks. If you need to let someone else in, you authorize their app on a one-off or permanent basis. Simple, secure, convenient.
There are a bunch of Bluetooth door locks on the way, and you can even lock and unlock your Mac via Bluetooth, so why not a Bluetooth padlock too? Noke is a Kickstarter campaign for a $59 lock where you simply click the hasp to unlock. Provided your phone is with you, and the app code matches the lock, it opens without key or combination.
Cleverly, you can also program the padlock with a Morse code-style pattern that you can click to open the lock if your phone battery is dead.
The campaign has an ambitious $100,000 target, so it’s by no means certain it’ll get funded, but as with all Kickstarter campaigns you lose nothing if it doesn’t make it. $59 is the Kickstarter price, with a planned retail price of $99.
The campaign doesn’t say anything about the security credentials of the lock, so it’s probably best considered something for relatively low-security applications like gym lockers and ‘cafe locks’ for bikes (ones you use just to stop someone hopping on and riding off while your bike is within sight).
