Control Data has a computer system in Cleveland which does nationwide credit 
card verification for several cards.  Remote concentrators and high speed 
telephone communications.  There are several other companies which provide a 
similar service.

Pleasantly enough, development is done in California, where I did some 
consulting for Service Bureau Corp.  What amazes me, is that if CDC (or the
others) approve a card which the issuing bank has invalidated, the approving
company stands to be charged for the loss.  And there is a huge amount of 
credit validation each day.  And some very enterprising individuals with 
quite interesting credit card scams.  I sure wouldn't like to have that
much risk.
