I think I did hear brick-and-mortar stores complaining recently about having too many customers, and wondering whether there was something else they could do, something they hadn't thought of yet, to annoy and anger customers, maybe add a little friction to keep them from walking in the door. /irony No but, ever since "the Schneier piece" [0] I've been thinking differently about this whole issue. It's about identifying you, and well, the store already knows exactly who you are as soon as you use your credit card. So does Amazon.com of course, though ironically they might not have an image of your face. If you were going to that physical store and planning to use cash (or shoplift), THEN this affects you. Although even without "AI," you would still get captured on security cameras. So if your presence there became a matter of interest - let's say for example, to corroborate or debunk your alibi for a more serious crime elsewhere - someone would invest the time to identify your face the old-fashioned way. Like probably a subordinate of the senior detective on the case, watching hours of camera footage looking for you. You can see how it was a series of small, slow, incremental steps, each one not necessarily big enough to create an uproar, that got us here.

I work on identity resolution problems among other data challenges at a big retailer. We get very few details when a credit card is used in-store -- pretty much just the basic card info. We don't own the payment networks and a variety of legal and business reasons prevent us from doing what may seem to be possible to get an individual's data based on a card number (from the networks themselves or other data brokers). What's possible is mostly limited to what you can do with the name on the card and store location. We've invested significantly in the problem and the answers are a patchwork of guesses. There's an interesting related issue here for brick & mortar businesses with CCPA and GDPR in effect: you can do some useful analytics, personalization, and fraud prevention work with probabilistic identity info, but if someone verifies they actually are Person X and wants to download or delete whatever data you have on them, what can you confidently say is actually their data? Will companies be held to different standards based on how much money they've invested and success they've had in identity resolution, in which case this might be a factor dissuading them from doing more identification and personalization? Or if they haven't invested millions in trying to figure out who people are, but it's possible to do so, are they liable for some kind of misconduct if they don't produce all the data they have that could have been tied together for that person? Is the choice binary, i.e. either invest big in identity resolution and take it as far as possible (with parallel governance investment) or de-identify everything you can? A privacy advocate might think on first pass that it's as simple as choosing the latter, but that's mostly not possible due to requirements we face related to other regulation and business realities: fraud, anti-money laundering, age-related laws, shoplifting, intense competition in a razor thin margin industry, etc. Data privacy is complicated.

  Hobestly it doesn’t have to be. Ban majority of data collection aspects and be done with it. We are wringing our hands over the issue when in reality we can solve it like the Gordian Knot.
