on CardSpace. What it is, how to use it, and how to design systems
that take full advantage of it. Part II introduces the technology
and the basic use cases from the user and developer
viewpoints. Part III then goes into more depth about what it
means to be an RP or an IP.

Windows CardSpace
Now that the advantages of the Identity Metasystem have been
explained, let??™s take a look at what Windows CardSpace is and
how it works with the metasystem to provide a ?¬‚exible, usercentric
model for managing digital identities. This will provide a
strong foundation for understanding CardSpace, including what
the typical user and web developer experiences look like. In
addition, this chapter explains what data is on a card and what
a card actually represents. This discussion is followed by an
overview of some of the common tasks a user might want to
perform in CardSpace.
CardSpace Walkthroughs
A good way to begin understanding Windows CardSpace is to
see an average user??™s experience and then take a look at the
same scenario from a web developer??™s perspective.
