I stopped using credit cards in the 1970s because it reminded me of my [first
] ex-wife. Now I'm reluctant to handle cash with my bare hands because reasons.
I've determined I'll need to get a smart phone, and fortunately the $150 Pinephone is shipping. It runs any flavor of Linux rather than iPhone or Android OS. I know it's easy in some countries to do contactless payment
via QR code. Is that possible in the USofA?
