I'm confused as to what a "cashless card-based transaction" would be. I'm wondering if they meant 'contactless'. That would fit with the other concept. As long as the infrastructure is up, they may prefer contactless or mobile pay, but what do they use when the infrastructure to accept ANY card is down? I understand the European chip model is slightly more resilient in this regard-- the idea of not being able to get a live authorization is a little more baked in, and you can fall back to "we expect to settle the transactions a few hours or a day or two later" concerns. I suspect the standard practices go out the window for a long term siege.
