Once upon a time(tm), Google had a great solution for that: You could get a credit card in nano SIM format, and insert into in your dual-SIM phone.

That then allows you to do secure NFC credit card payments even on a rooted phone with custom ROM.

That doesn't work when someone has multiple or virtual cards. That also means if someone steals my phone they get my credit card too.

Not a great solution.

You can load multiple card identities onto the same SIM and select the one you want to use.

Which hasn't been an issue since Chip & PIN became required, 22 years ago (at least over here).

I think some banks still do this with NFC instead?
Do you have more details on the sim credit card?
