Not 100% true: I know some places in Norway that have unreliable internet connectivity, where they have terminals in the store that will save your purchase and wire it to the bank when connection is restored. Of course, this means you can over-draw your card, but I’ve never heard of that being a big issue in those small places.

Also, I can tell you from personal experience, cards were working Monday during the blackout. Not on wireless machines obviously since we had no cellphone reception, but for example Supermarkets were letting you pay with a card.

Solar panels are enough for power during the day.
