The idea is that the user knows how
to use real cards, so he or she can easily adapt to virtual ones.
Other Identity Selectors
Although CardSpace is the Microsoft implementation of an Identity Selector, it is
not the only one. The protocols and standards used by CardSpace are intentionally
available for others to use and build interoperable systems. Work is being
done on several different implementations of Identity Selectors that can run
cross-platform, including Mac and Linux. Notable is the Bandit Project??™s
DigitalMe Identity Selector. To learn more about non-Microsoft offerings that
work with the Identity Metasystem, check out the Open-Source Identity System
(OSIS) site at http://osis.netmesh.org.
Information Cards
are not physical
cards
179
For Information Cards to provide a truly effective user experience,
they need to mirror our real-world experiences with physical
cards. That is why the card metaphor was selected; it is very
?¬‚exible and naturally satis?¬?es the scenarios that require digital
identity. In fact, cards work so well as a representation of digital
identity, looking at the cards in your wallet is a very illustrative
way to think about Information Card use cases.
