almost all retail credit card transactions go over the internet and commerce seems to continue fine.

but if you want to be safe, have a cellular backup network.

seems way simpler than pushing out a k8s infrastructure to every store.

Payment processing doesn't go through the k8s infrastructure, they said. And lots of it still uses Tel/dedicated network lines already, especially in places like malls (where lots of restaurants probably are).

Aha! But - We’re only considering payment processsing. What about the actual operations of the store? I’m guessing the fry machine is controlled by the same infrastructure.

And surveillance cameras, and smart locks on any safes, etc.
