Why does Windows CardSpace remember the sites that I visit?
Each of your cards stores its own card site history and a record of the card data that you send to each of the sites. This enables Windows Card Space to alert you anytime that: A new site requests a card. The identity information or privacy statement of a site to which you sent a card has changed. A site to which you sent a card requests new data. Card site history is encrypted when it is stored on your computer. You can review it by viewing the site history in Windows CardSpace. Your card history information stays on your computer. It is not sent to a site requesting a card or to Microsoft.
