AI, yes.

Once got flagged for theft because the camera saw me put a box down on the far side of the scanner and then used the handheld scanner because it was large. Evidently the box getting past the fixed scanner without scanning triggers theft even if you scan it.

In a convenience store, I put products on a platform and I don't have to scan barcode and it just "scans" my whole order all at once with machine vision. It worked well for me, but seems to have the clerk on high alert to watch it like a hawk from any mistakes, which sounds exhausting. I got the sense that it screws up a lot and the clerk is on the hook for it.
