Online event ticketing service StubHub, which recently announced support for iOS 6's Passbook feature for iPhones, is expanding its offerings into e-tickets for college football games hosted at four US colleges, the first batch of what the company says will be more than 60 partner teams in the near future, including professional sports teams. The integration lets fans add e-tickets purchased through the StubHub Tickets app to Passbook for automatic display when they arrive at the venue. The e-tickets will be available for the next home games for each school.
