Follow-up, going to add money now but learning why for the modest bunch, this is genius. I spent a bout $5.50 USD to get a drink for my girlfriend and I. When I go to the Starbucks reload a card site, I have to put at least $10.00 USD on the card. What's more is this made me really think about the idea of Google Wallet and any other phone-based credit card apps. In theory, I could take a screenshot of anyone's card and just mail it to myself. Does anyone know if there's plans to randomize barcodes/symbols to prevent things like this? This really just brightened up my Sunday evening.
