Re: Opting Out?
I think they're trying to prevent fraudsters from misusing credit cards.
One of the checks done to spot fraudulent use involves comparing the country of the card issued with the country identified from the current ip address of the person using it. If they don't match the transaction is flagged as potentially fraudulent. Depending o the processor's rules, it can be denied. Using a VPN would make this less effective, not to mention you don't get an ip address for the possible fraudster.
