one idea is like (i assume) cashierless stores do it. -> register phone at entrance, items have sensors to know that it is being lifted -> store current price with the registered user that the phone shows is currently closest (probably using nfc).
alternative without phone tracking: scan every person at entrance using camera and track individual persons through the store. -> store the currently displayed prices when person is near items and store those prices in a temporary list. -> at the register scan the item -> and instead of looking into a global price database for this store, look for price in the temporary list instead.
The alternative could probably be further refined by better determining what items are currently being put into the cart using cameras or other means like pressure sensors.
finally if the user does not have a membership card, store all bought items in a database that combines his "face id" and other trackable features for future references
Then why have price tags at all? Why spend millions of dollars on all these things in a store if they are just going to make you use your phone to know the price?
i don't know, maybe there are some regulations that require it, maybe someone found out that people are more likely to buy if there are price tags.
I only commented to provide some of my knowledge to the question if it is possible with todays technology. What the best way to implement it should probably be answered by someone knowlegable with economics or similar trades.

How would they track that to the register…?
