I've been trying to beef up security on our site, as we've had a few chargebacks.

I'm using PayPal Website Payments Pro

When testing checkout using my own credit card, I noticed that the transaction went through fine when:
Name on card did NOT match
NO CVV was entered.

I can't find any setting, that forced the check of name, or one that ensure the CVV is checked and matched.

Anyone know how to do this?

Thanks a lot!
