Unfortunately the fact that NFC can’t be used on anything that’s rooted anymore is kind of a deal breaker.
NFC can be used on GOS, and they frown on rooting.
If I could use google pay and my normal banking apps with GrapheneOS I would switch to it today.
It’s due to PlayIntegrity API wanting a “Google certified OS,” which is ironically less secure than hardware attestation that GOS supports. I doubt Google would change their model, but your bank might. Some banks do support GOS, and they have changed at the request of their customers before. Send them the GOS documentation and you might get lucky.
