I've never been in a walmart, but do they have the "shoppers" cards like many supermarkets do, which could track buying habits of an individual shopper.

Otherwise, if it's just tracking store data, rather what the store is selling, rather than what I am buying, then I'm not sure it matters, it's the easiest way for the store to know what to stock and what to not stock, as well as helpful info as to what to run sales on.
