COLUMBUS (AP) — Ohio State University is ending the use of print-at-home tickets to athletic and other events as fakes have become an increasing problem in recent years.

The associate athletic director for ticketing, Brett Scarborough, tells The Columbus Dispatch the change was made when tickets went on sale for winter sports this year. Scarborough says printed tickets won’t be allowed at football games next year.

Scarborough says fraudsters sometimes create fake print-at-home tickets or alter real tickets to look like more expensive seats to increase their price.

The school is urging fans to rely on mobile tickets on their smartphones, or more traditional hard-copy tickets.

Ohio State recommends fans avoid resellers and instead use authorized ticket platforms, including its own ticket office, Ticketmaster, and the Ohio State Ticket Exchange.
