USB Combination Lock
You know those tiny little locks you can place on your luggage to prevent theft? Ok, ya, they don’t actually stop anyone getting in, but at least it serves as a deterrent to would be thieves, and in the event someone does break into your crap you’ll know sooner than later. The USB Combination Lock is pretty much in the same vein. Just insert your USB device, lock and presto, your mouse, USB flash drive – just about anything USB – is rendered useless until your friendly IT team takes a hammer to it.
You can grab one here for about $6
