I should have given more information on how I'm processing cards.  I
use the standard IC facilities to encrypt the CC info via GPG and have
it emailed to me, then I process it via a virtual terminal.  I was
wondering if the CVV info had been incorporated into that encrypted
block along with the account number and expiration date.  The reason
for all of this is PayPal's virtual terminal requires the CVV info so
I need to start collecting it right away.
