I have long-suspected that Walmart has facial recognition
Had heard the rumor as well
It’s definitely not a rumor. If you try and search the name of the facial recognition system used you get an error.
It shows up on ours at the self-serve checkout registers—you can see your own face. Also, there is a large screen suspended from the very high ceiling at the entrances, angled downward so you can see yourself entering the store. Presumably to deter shoplifting, but like any other collected data, vulnerable to misuse by government or other marketers.
