The
elements that describe the card and the IP found in the card are
the following:
Card ID. The card ID is used to index the card. Only one
card with a particular card ID can be stored in the card
store. An attempt to load in an additional card with the
same card ID will notify the user that the card will replace
the previously stored card.
Version. The card version is used by CardSpace to determine
whether a card is newer or older than an existing
card in the store. In any case, users are noti?¬?ed when

they attempt to import a card with the same card ID, and
they can decide from there what to do.
Card name. The card name is the label on the card when
it is imported into the card store. The name of the card is
the only thing that the user can modify.
Card image. The card is imprinted with a single image of
the issuer??™s choosing. The image can be of any size; a
scaled version is copied into the card store at card import
time. CardSpace scales the card image to ?¬?t 120?—80
pixels in the Identity Selector and will also scale the image
dynamically to 90?—60 pixels on other pages.
