The Washington Post has highlighted an interesting facet of the recent million dollar card mega-scam that can also get retailers thinking. Apparently, the numbers obtained by this group for European credit cards were worth $50 apiece on the digital black market, whereas American cards only brought $10 (Canadian cards, if you were curious, are supposedly worth $15 each). 

With such a huge gap in value between these different options, it seems as if point of sale credit card processing systems that take in more highly prized cards might want to pay special attention to vulnerabilities.

The Post article investigates as to why this stratification occurs, and part of the answer stems from security flaws in these cards that are easier to exploit. In addition to European accounts being more exotic to U.S.-based card criminals, differences between card processing systems overseas can mean that it takes more time for international payments to go through. In that time, the perpetrator can have a field day with the numbers they've obtained long before any existing security checks kick in.

There may be little a retailer can do in-store to change this for now, other than keep customers aware and make sure their credit card processing software is clean and trustworthy. But since this is an evolving struggle, even that little bit can be enough to help reduce the chances of being defrauded.

Customers and companies can be put at risk without even knowing it, and if your business sees a lot of foreign traffic, it can be especially worth it to look for measures that can benefit those consumers particularly.
