I think I know what you are getting at with supermarkets, but with Walmart in particular, they have been going quite heavy into serious tech, and all in-house lately [1], [2]. Not to disagree with you, was more an interesting thing of note for me. I didn't really picture Walmart doing this sort of stuff outside a huge IBM or Oracle contract. Retailers of that scale have all sorts of potential improvements to make from the growth of technology from online to mobile to IoT (maybe) to big data analytics on purchase/loyalty schemes.
