You can now pay for your Starbucks latte with a cell phone instead of a credit card. Nearly 6,800 company operated Starbucks stores in the U.S. will begin accepting mobile payments. Owners of Blackberries, iPhones or iPod Touches can use the system by downloading the free Starbucks card app. You just wave the phone in front of a scanner and money is taken from your Starbucks account.
