At least in Finland's Nordea bank you can order a physical code calculator, they used to be small enough to keep on your wallet but the new one is the size of an old small phone. It even has a QR scanner. So I just keep it at home.

I actually had no idea, I thought they retired these, but it seems that one of the models is still available. Thanks for the heads up!
