Is there a good reason to require people to id theircredit card?

A credit card number is a unique identifier. No need for additional
qualifier. And more and more the trend is against having ppl make that
choice. Saw a site recently that had it AFTER the card number field and
it auto populated based on the first number in the card. Nice way to
confirm/reassure without requiring me to do redundant work.
Given that it's fairly easy to identify what kind of credit card someone
is using (Visa/MC/Discover/etc), is there a good reason to require
people to select the flavor they're using? I can imagine that people
might get confused if they're not asked, but I'm curious as to whether
there's any research for or against.
