This may be old news to some, but I hadn’t stumbled across it until recently. With the proliferation of smart phones, many printed vouchers (gift cards, airline boarding passes, etc) have been replaced with images of bar codes or QR codes you can display on your smart phone for a scanner. Jonathan Stark, of Rhode Island, decided to try an experiment with his Starbucks card. He put $30 on it, then published the QR image on his web site. Need a coffee? Have one on him. Feeling generous? Buy a stranger a coffee by putting money on the card. Even Starbucks corporate thought it was a neat idea and was following the story with interest. It worked, too. Thousands of dollars were run through the card before it was revealed that Sam Odio had found a way to “skim” small amounts off the card and transfer them over to his own account. While he claims he planned to auction this loaded card (value: $645) on eBay to raise money for charity, Starbucks has decided to close Jonathan’s public experiment down. So except for one moron ruining it, the experiment looks like it was a success. The goal? Restoring a few people’s faith in humanity.
