I think the parent poster was asking how consistent that is across geographic divides. I notice the same effect: I live part of the year in a city where public transport requires either a smartphone or tap-to-pay, and the rest of the year in a rural area where nobody assumes you're carrying a smartphone. It seems to me at least that urban areas are standardizing on requiring people to carry a smartphone for tickets, passes, even menus in some places; while this hasn't caught on in rural areas. I would bet that people in rural areas will regard Apple's event ticket maker as alien to their lives and a sign of some sort of urban folly. I wonder if there's a similar urban/rural division on users of Apple's Invites app.
