From the Waste Management Phoenix Open site:

The Waste Management Phoenix Open is now the most technology-friendly golf tournament on the PGA TOUR, evidenced by several “firsts” that help spectators responsibly use mobile devices without disrupting play and by offering unparalleled access to services, information and fan/tournament interaction.

“We’re dedicated to enhancing the fan experience at the WM Phoenix Open,” said 2013 tournament chairman Tom Altieri. “The new technology at this year’s tournament is outstanding and makes it easier for fans, vendors and sponsors to connect with each other and interact with the tournament.”
