Using cameraphones to combat ticket fraud in Barcelona

A soccer team in Spain is using barcode scanners connected to cellphones to verify the identities of season ticket holders and make sure they don't sell their tickets or give them to someone else. It's crazy enough that Futbol Club Barcelona went out and took photos of some 112,000 ticket holders, but we're finding it hard to believe that thousands of people showing up for a game would all be able to wait the 90 seconds it takes for turnstile workers at the club's stadium to scan each ticket holder's card and then wait for their photo to appear for verification. Either they're only checking a relatively small number of people, or fans must be lining up hours earlier to get in. And now that we think of it, why exactly is this a problem that needs solving in the first place? If you paid for a ticket and you can't go, why shouldn't you be able to give the ticket to a friend?
