The Gatekeeper keychain is a keychain that knows how close you are to your computer and when you reach a certain distance it will lock your computer, and when you return it will unlock it for you. Great for IT workers that need an extra layer of security, when you're at the coffee shop working on that "novel", or for guys who have loads of weird German dungeon porn on their computer and internet history that they don't want anyone to know about. Don't worry that folder on your desktop labeled 'files' is so obscure that it certainly won't raise any attention to itself. The Gatekeeper keychain uses bluetooth 4.0 technology with an AES encryption method to keep your data secure, it has a range of up to 100 feet, measures 20mm x 36mm x 5mm, and weighs just 4 grams. The Gatekeeper keychain is coming soon to Kickstarter, so keep an eye out for them in the coming weeks, and be sure to check it out in action via the video below.
