yeah in the virtual terminal there is only a place to block specific card numbers or IP addresses. the link you sent says:
What fraud protection measures are included?
Fraud protection measures included with all Global Gateway(previously LinkPoint) payment services are: Address Verification System (AVS) Card verification schemes (CVV2 and CVC2)
Merchant-configurable fraud protection. Merchants can block customer names, IP or class C addresses, domain names, and specific credit card numbers. Merchants can also set automatic lockout times. These are set in the Admin section of Global Gateway(previously LinkPoint) Central.
But it doesn't seem that the AVS or Card verification actually works. I put in wrong addresses and fake CVC codes and my card still goes through. It makes no sense to me.
I can't be the only one here that is having this issue??
