Microsoft Windows CardSpace is a system for creating relationships with websites and online services. Windows CardSpace provides a consistent way for:
- Sites to request information from you.
- You to review the identity of a site.
- You to manage your information by using Information Cards.
- You to review card information before you send it.
Windows CardSpace can replace the user names and passwords that you use to register with and log on to websites and online services.
When you visit a website that accepts an Information Card, that site indicates what type of card it is willing to accept. The Windows CardSpace user experience shows you which cards in your collection meet the requirements of the site. Before you submit a card to a site, you can inspect it to see what personal information will be sent. You should also review the privacy statement of the site to understand how it uses your personal information.
