Everyone hates it when they lose their keys. Worry no more. The GateKeeper GK-Chain, a Bluetooth 4.0 proximity tracker key fob will help you prevent item loss, locate items, and automatically log you off of your computer when taken out of proximity.  So, instead of typing in your password every time, the device unlocks your computer when you approach, and locks it when you leave (you can also set the GK-Chain to require a key and password).

How it works? All you have to do is to sync the device with your smartphone and attach the key fob to your valuables -bags, purses, dogs. What is even more interesting is that Gatekeeper GK-Chain also allows you to use it for different scenarios. For instance, parents can be warned if their children go out of a certain range. The project has been successfully funded on Kickstarter and is now available to pre-order.

What Sparks our Fire: A useful device can help us save time in our daily lives.
