There was a recent story about some guy who had been buying season tickets for decades by paper ticket. The stadium shutdown the paper ticketing and left him without an option, except to purchase a smartphone.
Must be a Europe thing, as RealID pissed enough boomers off here in the States that I doubt anyone would push harder than that, and outside of very stupid ticket apps that occasionally won't let me print, I can't recall the last time a paper ticket and my drivers license didn't work. I also can just walk into a bank branch and raise a stink whenever I need something banking related, I guess all of this feels really contrived.
