Each number is then mapped to a character
using the Table 3-2. So if the numbers were (5,23,13,11,16,8,20,12,5,31),
the resulting ID would be 5RD-BG8M-C5D.

An intentional property of the characters chosen is to avoid confusion by omitting
characters that look similar. For instance notice that no numbers map to
zero (0) or the letter O.

Managed Information Cards
CardSpace supports the handling of digital identities by remote
IPs in the form of Managed Information Cards. They are referred
to as Managed Cards because the information is managed for
the user by a third-party. Unlike Personal Cards, where security
tokens are created using claim values stored on the user??™s machine,
security tokens created when using Managed Cards are
generated on a remote machine, where the claim values are
stored. The token does not originate with the client??™s computer,
but from a service hosted by the IP, which runs an STS, as discussed
in the section ???WS-Trust??? in Chapter 2 .
