What is Windows CardSpace?

These days our online lives look a lot like our offline lives. We hang out with our friends. We shop. We’re entertained. So, just as you wouldn’t leave your house without your driver’s license or other identification card, it makes sense that you need a similar information card to use online.

Windows CardSpace helps you control your digital identity, which helps make online activities (like shopping and social networking) safer and more efficient.
