Of course, coming up with a brand new system for processing payments is not
simple. CardSpace doesn??™t support sending data from the RP to the IP, which is
necessary to communicate information, such as transaction amounts. However,
nothing prevents devising a payment solution that works with these limitations.
There are already examples of such initiatives in the market.

Department of motor vehicles. What does this IP know?
The DMV collects data of several types. First is information
that is asserted by the cardholders: their physical
data (height, weight, hair color, eye color, and gender)
and their current address. Second, they collect copiesof
some pieces of data, namely the cardholder??™s date of
birth and a photograph. Finally, there is data that the
DMV is the authority for: what classes of vehicle the
cardholder is permitted to drive, the record of driving
infractions, and an optional ?¬‚ag to be an organ donor.
How do they know that?The ?¬?rst category of information,
that asserted by the cardholder, is not strictly veri?¬?ed
(although it is mandated by law to be accurate and current).
The second category of data often relies on another
piece of identi?¬?cation (birth record or passport), and as
long as the DMV trusts the issuer of the original document
(or that the person whose picture is being taken is
legitimate), this information can be considered fairly
validated.
