Wero makes it worse not better.
With wero you must have play integrity and you can't even have developer mode turned on which is frankly ridiculous. I don't know of a single app that requires that. Source: https://support.wero-wallet.eu/hc/en-us/articles/25599098295...
They had a great opportunity to make an ecosystem not dependent on google and apple and they utterly failed. You can't even log into it on the web, you must use the app.
My bank app scans Wero QR codes and works fine on a rooted custom ROM, maybe after dismissing a popup about weird software, as long as it's already custom and rooted at the time of setup.
It would be a pain if your bank wouldn't provide direct Wero integration, though.
That's for the Wero wallet app specifically, no? I use iDEAL through my bank app and it works great, I'd assume it won't change with Wero since it's basically the same thing
