@joepie91 @jonny I agree with you, just to add to your point: card networks aren't free either. While it costs to handle (and even make) cash, the card network operators also levy fees on transactions. Taking payments costs money. No idea what Google and Apple do but I bet it costs on top.
I'm very much against the push to move payments but also banking authenticators to phones.

I had an ebike that unlocked via an app, except when it didn't want to connect with Bluetooth. There was a hardware override, but it was a pain in the ass in so many ways.
Keys work fine, no, custom apps because.
Anything that requires an app is just going to fail you when you need it most.
