This is possible in retail, or will soon be.
Canada's major grocery chain has migrated entirely to LCD price tagging that can receive OTA updates. There are now no paper price labels in the store.
The same chains have extensive camera coverage on the entrance / exits of the store.
So pricing can be an optimization function as fine grained as persons currently in the store.
Cameras on the aisles as well can enforce that individual tags update while nobody is within 15 feet, etc.
It's hard to even talk or think about without without sounding (and becoming!) conspiratorial. Add a little data from our trusted partners and they can jack specific prices according to urgency - eg, floral bouquets when you're en route to a dance recital.
The electronic shel labels use e-ink. Their refresh time is around 30 seconds. What happens if two shoppers are looking at the same product?
Since you get a location and time stamped receipt these shenanigans would be completely trivial to detect.
It’s hard to talk about without sounding conspiratorial because it literally is an unfounded conspiracy. The impracticalities of this scheme are immediately obvious and no evidence of it ever actually being implemented in physical retail exists.
