Not an answer to your question, I'm afraid, but helpful for others
searching on this topic:

Some credit card auth providers charge a small amount for each auth
attempt, and visitors to your site can enter a nonsensical credit card
number (accidentally or intentionally), resulting in a small charge for
you to pay your provider to check this.

A good idea is to check the card #s for basic checksum sanity *before*
your submit for authentication. There's a credit card checking algorithm
in the CVS repository for Plone Collective (not Plone specific, tho')
that can help with this.

I've used the online card auth systems offered by my client's banks
before, and that's worked out well, but it's usually more expensive of a
discount fee than the big places charge, so I can't really recommend
those. ;)

Good luck!
