One of the main tell-tale signs of fraud is when the country the card was issued in does not match the country the card is being used in.

What you need to remember is, not a huge percentage of your customers are getting this message, just a few who for some reason are using their credit cards outside the card's home country. And, if the message was not there, the result would be a simple decline.

I lived abroad for years while continuing to bank in the USA and basically gave up paying for anything with a credit card online, outside of Amazon.com who were always cool with me.
