First Data's GO-Tags May Replace Cash and Credit Cards
Steve Hamm writes for Business Week about First Data's GO-Tags for contactless payments - "demoed this week at the Democratic National Convention in Denver, where First Data is based. The company demonstrated its newest technology, called GO-Tag, by distributing small buttons to 5,000 journalists and delegates. When they tapped the buttons on electronic sensors at concession stands in Denver's Pepsi (PEP) Center, they got free snacks and drinks."
