An increasing number of musicians are holding summer tours where ticket holders must present an ID at the venue on the day of the show in order to get inside. These tickets are usually reserved for the most desirable seats, and about 400 summer dates will feature such tickets, representing a more than 100 percent increase from last summer. Although some artists and fans see this as a way to counter the growth of high-priced resellers, others are worried about buyers' rights. "It's not that they are paperless that's the issue, it's that they are non-transferable," says Fan Freedom's Christopher Grimm. "Our fear is that eventually every ticket will be restricted, which means if you want to get rid of it, you have to play by the rules of the company that sold it to you." StubHub CEO Chris Tsakalakis says the real goal of the paperless ticketing effort is less about cracking down on scalpers and more about giving ticket companies resale rights. "None of this would be an issue if, as with many other industries, consumers who couldn't make use of the product could just get a refund," he contends. "But the ticketing industry has never been customer-friendly."
