There’s a good chance that if you have a laptop, there’s an empty PC Card slot just waiting to be used. Sure, you could always add some extra USB ports or a 3G card, but if you don’t need anything that fancy, why not do something simple with it like turn it into a secret stash?
This tiny Stash Card will let you keep a few very small items stored away in your laptop. Perhaps a spare key, or a few bucks. I wouldn’t stick anything of value in it, as it can be swiped just as easily as your laptop. For $8 you can’t really go wrong.
