Let's orange pill supermarkets. When you can buy food and everyday things with btc, it's a lot easier to offer as payment between people and eventually unbank yourself. No KYC required at PoS, yet.
Supermarkets need low friction payments, high throughput. Need bitcoin integration at PoS or payment terminal level. Preferably NFC.
Most payment terminals in Finnish supermarkets are Verifone. They announced BitPay integration in 2021, but haven't heard anything since. Is it actually available and deployed somewhere?
