My question is why are the systems designed to be dependent to upstream services 24/7? Wouldn't a better approach be to have systems that can run disconnected, then simply upload/replicate data when a connection returns?
These are franchises, right?
I deployed such POS (Point of Sale) systems in the late 90's, because connectivity wasn't ubiquitous then. They were designed so franchises could upload/replicate however you needed: continuously, when a connection was available, on a schedule, etc. Some places had pooled telephone lines to achieve the needed throughput.
I get the mobile ordering being impacted, but why would you tie the local kiosk to a web service?
