Gaël Duval, the lead developer behind /e/OS, has been recommending an app called Zettle [on his blog](https://gaelduval.com/practical-payment-solutions-for-murena-and-e-os-users/). It at least work on degoogled /e/OS, probably GrapheneOS as well. I have no personal experience as I prefer sticking to cards.
