Measuring 20 x 36 x 5 mm (0.78 x 1.41 x 0.19 in) and weighing 4 g (0.14 oz), Gatekeeper is compatible with PCs running Windows 7 or later
Users plug a USB lock into their computer, which then communicates with the fob using Bluetooth 4.0 within a range of 100 ft (30.5 m)
The distance at which the fob will work is adjustable, meaning it can be set to unlock the computer as soon as you enter the room, or only when you sit down at your desk
For some office workers the task of locking and unlocking their computer is a regular part of the job, while for others it's frequency is dictated by the extent of their caffeine addiction. Looking to automate this process is the team behind the GateKeeper Chain, a key fob with a built-in proximity sensor which automatically locks your PC when you walk away and then unlocks it when you return to your desk.
