This one’s a pretty cool invention that allows you to lock or unlock the door in your house with the use of a phone (runs as an app on iOS and Android). Check out the video below how it works.

As you can see from the video, the device is attached on top of the lock on your door and is controlled remotely but an app in your iPhone or Android phone (option for SMS activation is also available). It’s still not yet out but reservation is ongoing for $149 a pop.


An invention? Nah I don’t think so. This kind of device was already common. We weren’t even allowed to make something like this as part of our project study. That was way back 2007.
