NEW YORK ( TheStreet Ratings) -- With billions of dollars of purchases coursing through the retail sector every day, technology companies like Google ( GOOG) are teaming up with Citigroup ( C) and MasterCard ( MA) to introduce mobile wallet payments made with smart phones. Fighting to retain its leading position in online payments, eBay ( EBAY) is suing Google alleging intellectual theft. There are even Apple ( AAPL) applications, such as Square, that help turn iPhones into credit card readers while avoiding the need to open a traditional merchant account. With Square, your garage sale can now accept Visa ( V), MasterCard, American Express ( AXP) and Discover ( DFS).
One of the benefits to technological innovations is the ability to charge relatively high fees on each transaction. Plus, small amounts of millions of transactions can really add up to big money. Don't count out the players who have been in the payment processing game the longest. Dow Jones U.S. Financial Services Index Fund ( IYG) holds proven payment leaders Citigroup, Visa, and American Express among its top 10 holdings. When selecting an exchange-traded funds to cover the tech companies positioned to take advantage of mobile payments, take a look at Internet HOLDRS ( HHH) which is weighted to 19.7% eBay and 46.7% Amazon.com ( AMZN). Or, for a more diverse tech ETF, consider the First Trust Dow Jones Internet Index Fund ( FDN) with Google as its top holding at 8.5% of assets. -- Reported by Kevin Baker in Jupiter, Fla.
