Those RFIDs make it possible to not just scan them when the article gets bought, but also to very easily scan the inventory of the whole store by just walking through the store with a scanner.

Just as useful, although currently still more likely to be done with barcode scanners is to identify the products in the logistics chain. Right now you need scanning ports with at least 4 cameras/scanners or humans manually scanning each barcode, with RFIDs the port would be simplified further.
