>They're trying to prevent people who purchase the season pass to almost exclusively resell tickets to individual games.
Why do you need a smartphone to do this when a white list checked against ID at the door would suffice? As the other respondent says, you either generate a badge for the passholder, or have an approved list of guests that can use the season pass if the passholder chooses to offer it to others.
And that will slow it down for everyone. Not to mention that HN users will then whine about the surveillance state
Generating badges has loopholes. (Trust me I’ve used them). And IDing every person can be a mission on itself. Pretty sure they will just start using biometrics in the next decade with or without your consent.
