The university that I'm at is trying to get new students to use a digital student id that uses google wallet for scanning I think. They aren't giving any new students physical student id's unless they need it for something that doesn't work with the digital ones.
as someone who runs GrapheneOS and looked into the possibility of doing contactless payments: no. it simply does not work. all the contactless payment apps can somehow detect you're not running the stock OS for the phone and choose to lock themselves down.
cashapp and venmo will also freeze your accounts almost immediately upon installation and login and, in my case with cashapp, insinuate you may be reported to law enforcement for fraud when you appeal with info about your phone lmao
