Don’t worry just buy this wallet removable card holder that attaches to your phone but comes off so that you can keep it separate when charging or putting it down, or trying to hold it in your hand without a big bulky thing that keeps popping off.

And don’t worry, the magnets no longer affect your credit cards just, hotel keys, cheap gift cards, bus passes, etc…

Yeah sometimes classic ways are still best or you find you really don’t need something you give up for efficiency, just do you and it’s fine.
