Protecting age-restricted markets
In many parts of the world, purchasing alcohol is
restricted to customers of a certain age. Selling alcohol
on the Internet is not a common practice, partially due to
the lack of capability to validate the age of the
customer??”which is a bit odd, given how common alcohol
sales are outside the Internet. Again, an Information
Card that contains a validated age claim could easily
satisfy these conditions.

As mentioned in the sidebar ???Payment Cards??”Ready for Prime
Time???? in Chapter 6, using CardSpace to manage payments isn??™t
fully supported in the current generation. (Although an implementation
isn??™t impossible, it would be nontrivial and require
signi?¬?cant testing.) That doesn??™t rule out the ability of ?¬?nancial
institutions to use Information Cards to transmit credit card details
right now. The rest of the system for processing payments
wouldn??™t have to change at all??”just how the merchant receives
the credit card information. This would provide the ?¬?nancial
institution the opportunity to authenticate the user before releasing
the account details, cutting down on fraud. In addition, the
?¬?nancial institution could give out one-time-use account numbers,
eliminating the possibility of the account information leaking
out after the current transaction.
