US sports are already headed there. Proprietary apps help them control (eliminate) the secondary market in two ways: they broker transactions between people (app-to-app) and prevent scalpers from transacting paper tickets.

MLB, NFL, NBA, and NHL all do this with league-branded apps and/or partnerships with Ticketmaster, etc

With my current MLB tickets I can take a screen shot of the ticket and text it to somebody else. Much easier than a ticketmaster transfer. The world cup is using a time base code to prevent any transfer of tickets.
