clarification: NFC payments in Google Pay. For example my bank app has mobile payments implemented and they work on GrapheneOS.

AFAIK the only reason why Google Pay NFC payments don't work is because Google Pay keeps a list of hardware and OS that's allowed to use that feature, and GrapheneOS is not in that list. It's not an OS limitation.

There was an open issue to spoof this data so that Google Pay NFC payments, among other Google features behind this check, would work. But it looks like it got discarded 2 days ago: https://github.com/GrapheneOS/os-issue-tracker/issues/1986

I think Graphene spoofs the most basic level of Google's security thing but they never wanted to spoof anything higher because it would just turn into a cat and mouse game that they would eventually lose.

They recommend that app developers adopt the much stronger and vendor-neutral Android hardware attestation API instead.
