Thank you for the replies!
I've done some research online and it seems like AVS/CVV fraud checks usually don't work with international credit cards; is this true?
My main concern is to use a payment processor who can handle international credit cards and have fraud detection methods in place to keep fraudulent orders low.
I'll look into WorldPay as well; have you ever had any issues with international credit cards using WorldPay?
I've also reached out to CyberSource to see what they have to offer. Does anyone have any experience with CyberSource?
