Tim Dickey, a retail specialist at POS vendor NCR, recently found himself being owed $100 by a friend who lived a long distance from him. (He had done some technology cleanup for her and had purchased a $100 application in the process.) The friend was going to use PayPal, but that would have incurred a charge, and they explored bank wires, which can also cost money through bank fees. Then Dickey, who is a frequent Starbucker, realized that she could simply populate his Starbucks card with $100. No charge, no delay, no risk. It was likely never considered a primary feature of the mobile program, but I doubt Starbucks would object if it became popular.
