I hear you on this. I believe if you don’t want to bring your phone to the game, or are concerned it will die before you get through the gates, you will have the option of printing a hard copy ticket at your home (or a public library, etc.), and bringing that. I don’t know the percentage of people who buy tickets to games, are not willing or able to bring a smart phone to the games and do not have the ability or knowledge to print a hard copy ticket. I believe they will have the ability to send their tickets to a friend or family member as well, who can print it for them or use their phone to get them in.
This is inevitable. Hard bcopy tickets are going to go away. Just like receipts, hard copy pay checks, paper bags, paper money, newspapers and magazines. COVID accelerated the time line significantly.
I have some love for the old ways and as already mentioned, have some pangs of regret as this paper we used to use in some many ways goes away. I am comforted knowing getting rid of paper makes things more efficient, wastes less resources and saves money.
