The SF 49ers will soon have a new stadium in Santa Clara, CA. This May 30th article from the SF Examiner describes the new stadium as "entirely cashless and ticketless." The assumption is that "… the fans will be carrying around smartphones." "Software engineers are already building apps to order food, watch instant replays, listen to play-by-play and check bathroom lines from the seats."
As a mobile analyst, I love the concept. Has anyone every been to a conference though with thousands or tens of thousands or 68,500 people? How's your Internet connection?
I trust they'll test this.
