That’s because that camera is likely not only taking a high-resolution snapshot of your face but also storing it in a database for as long as that large drugstore chain chooses, with no other information associated to you. But every time you walk into that drugstore, or any of their other stores for that matter, the same system will capture another image of your face, and the algorithms built into the software will match the image to the ones it took the other times you came into that drugstore chain. And even though it won’t have your name and address, it will know an awful lot about when and where you’ve entered its stores just by having access to that data.
