The impenetrable moat around Visa (V 0.90%) and MasterCard (MA 1.15%) in the payments business may not be so impenetrable for long. In this segment from Where the Money Is, Motley Fool financial analysts Matt Koppenheffer and Patrick Morris broadcast from the Transact 2014 conference in Las Vegas, to discuss the broader payments industry, and how the lines of competition are getting blurred. While the massive payments networks of Visa and MasterCard have traditionally allowed them to maintain high margins and ward off competitors, new payments business models coming from the giants of tech like Google (GOOGL 2.70%), Amazon.com (AMZN 2.66%) and eBay (EBAY 0.11%) with its PayPal business could soon spell a changing dynamic for the big dogs in this industry.
