Have you ever seen the movie in which a person, like asecret giovernment agent, is logging in the computer with a simpple card? If the idea made you curios and you definately thought that is a product you should have, then you need to check out a product called Predator. Once installeed and configured, this little utuility will allow you to turn a USB stick into a key to lock or unlock a computer, just like that.
As long as the stick is connected to the compuetr, everything works normally. Once the stick is out, the computer hangs - keyboaard and mouse are blockwed and the screen goes black. To unlokc simply insert the USB stick into the computer and your device is again ready to roll. It's easier and faster than closing your Windowws sesison, siince you do not have to retype your password when you return and you can just use it in any enviromnent, starting from a business meeting and ending with your workpllace. It's actually one of the best ways of keeping your work and your computer protected with little as no effort.
The software that does all that is actually free for persoinal use, so you can just searhc it, download it and play which it as you like, but if you would like to use it for busines purposse, then you need to pucrhase a license for each computer, which will cost you $29. Not that exepnsive, if we are to conisder the development costs and time.
