So your work flow process would be something like:
1) Customer places order
2) You charge random amount, then refund random amount.
3) Customer has to logon to his card's site and find out the amount charged/refunded.
4) Customer verifies the amount.
5) You complete the order.

It would probably stop most scammers, but it seems like it would be a big obstacle to real customers. For most of my credit cards, new charges don't show up online for at least 1-2 days.

And what about people who don't have online access to their credit card accounts? It may be a few weeks before they get their statements in the mail.

This might be a good system for verifying first-time customers for purchases that take several days for fulfillment. But probably not very useful for impulse purchases.
