Can you not use a browser to access banking services? If not, you should vehemently complain and/or move to another bank. And while cash is better for privacy, you can always use a credit card instead of your phone.

You may be able to at the moment, but web banking is being increasingly phased out in a lot of countries.

If nothing else works, my suggestion would then be to buy a cheap Android phone just for that indispensable banking app. Just leave it home in a drawer powered off when not in use, and use your a degoogled phone for your daily business.

My bank recently asked me to "re-identify" due to regulations about fraud and me being a customer for more than five years.

Rather than asking me to come into a building in real life, the asked me to:

- download yet another app

- make a picture of my id card (front and back)

- hold my id card to bank of phone

- show my face in the front camera

This process got stuck in step 3, because my phone has no RFC support.

The morale? So much for using a cheap Android phone just for that indispensable banking app.
