Very cool---------I now can buy coffee at Starbucks using their mobile iPhone App. All I do is purchase a Starbucks card, load it up with $$, and register it at their website. I then download the Starbucks App on my iPhone, open it up, press "card" and my new balance comes up. I hit "touch to pay" and a bar-code comes up, which is then scanned at the register.
I love this App.
