I've seen places where people have their act together, the phone works, the money is there, procedure is a habit that has been streamlined - AND the store is actually set up to properly accept phone-based payment, the payment machine is in good working order.Its like the grocery store. I go in for fast trip and some moron is trying to pay with their phone.
They need a moron line for people who want to pay with silly ways.

I've been held up in grocery stores where a karen in front of me tries to write a check, and it bounces. That customer had no idea that she has no money in the account? WTF??? And I've seen people who had exact change in coins (yep, even pennies) get through the line in a reasonable amount of time.
Payment method doesn't matter, it matters that both store and customer have their act together.
That's your point, not mine and I don't want to frighten anyone. I am just saying how I do it to avoid problems with mail.Don't tell people they need to become propeller heads when they don't need to.
Please don't scare people into building their own infrastructure when more user-friendly options exist.
