GateKeeper is a Multipurpose Bluetooth Smart proximity tag that can Auto Lock and Unlock your computer, and keep track of valuables.

Many features, 1 device, and useful to everyone. A versatile Bluetooth 4.0 proximity tracker that performs item loss prevention, item locating, auto locks and unlocks your Mac or PC. Syncs with our Android app for even more functionality (and iOS iPhone if we reach our stretch goal). The GateKeeper (GK-Chain) is just the start of an amazing proximity technology product.

Instead of typing in your password every time, the GK-Chain unlocks your computer when you approach, and locks when you leave. Or, if you want additional security, you can set the GK-Chain to require both the key and type in the password for two-factor authentication.

The GK-Chains also serve as Bluetooth 4.0 trackers. Using our free companion app, you can find your GK-Chain with a Bluetooth 4.0 enabled smartphone. This way, you'll have a little more help finding your lost keys, wallet, bag, even your luggage at the airport.

The GK-Chain tracks the location of the key using a proprietary signal strength algorithm and locks/unlocks your computer based on where you are.

Is it secure? Yes! GK-Chains use a modulating, encrypted connection to enable only a unique key to interface with the lock. The password is encrypted and still stored on your PC, not the GK-Chain – So no one can steal it.

We've been working on the GK-Chain for a while. After several rounds of PCB designs for the locks and the keys, the manufacturer is preparing for the first production line for delivery by the end of July 2014!
