Home Depot's newer all-in-one computers at the self-checkout include an embedded camera.
Makes me glad I never - ever - use self-checkout.
I'm not interested in helping replace human jobs with robots just so a bean counter in a boardroom somewhere can buy a second boat.
Occasionally, the self-checkout "team member" will come over to me while I'm standing in line and offer to help me use the self-checkout. I tell her, "I'd rather not help {$company} replace your job with a robot."
I expect a lot of times they think I'm a kook. But every once in a while they pause and I can see the realization washing over their faces. Then I feel like I've accomplished a small thing that day.
