Firebox has today announced that it has started selling the Noke bluetooth padlock - which is thought to be the first of its kind.
The way it works is pretty simple: Rather than carry a key to unlock whatever it is you want to keep safe, you simply need to have the Noke app on your phone - and when you're in range, it will automatically unlock. What's clever is that because it all works digitally, if you need to allow someone else access to your locked up bike, you can have them download the app and then temporarily grant their phone the ability to unlock the Noke lock too. And because phones have GPS, you can easily see when and where your locks were last used.
The good news too is that if your phone dies, you can still unlock the padlock by entering a morse-code style tapping code on the back of the device. The app can handle multiple Nokes too - so if you want to keep lots locked up, you can easily handle it.
The only downside? If you want to pick one up, it'll cost a rather pricey £59.99.
