Alipay and wechat pay are not settlement mechanisms. They act more like wallets that you can transfer money in and out of, and there is very little interoperability because of this.

India's UPI and Brazil's Pix are better examples.

Canada's RTR has no chargebacks so it's not comparable to visa/mastercard where you can yank the money back up to 6 months later if the seller doesn't send you what they promised. Pretty much every modern phone can do tap to pay, you don't need an iPhone

nope you can just tap your phone on the seller's phone: https://squareup.com/help/us/en/article/7786-get-started-wit...

Same way you can tap your credit card on their phone to pay them. It's the same protocol, just with biometrics on the buyer's phone so the limit is $50k instead of $10k

Dude it's called "tap to pay": https://en.wikipedia.org/wiki/Contactless_payment

A credit card, an iPhone behaving like a credit card (AKA apple pay), and an android phone are all using the same protocol. Why don't you just try it? Pretty much every grocery store, gas station, etc accepts tap to pay. Any phone or card will work with any terminal. Like I said, the only difference between a card and a phone is that the latter has a $50k limit instead of just $10k.
