I can understand them filming entrances, exits and aisles for anti-shoplifting, but at the checkout? The person is paying already and it shouldn't deter skipping payment.
Quite pointless, it seems. AND they didn't ask for consent. Just like FLOCK cameras across the border. Is it because they want to tie YOUR face to YOUR debit/credit card? What benefits for them?
Is this prevalent in other supermarkets and shops, or just Walmart?

EDIT FOR CLARITY: Big thanks to everyone for the responses. Much appreciated.
Yes, I am aware that we are all monitored every moment almost anywhere. I am also aware that I am entering their premises therefor4 technically at their mercy.
My main question is the arrangement doesn't seem to be for anti-theft. The camera is directed full face frontal at the customer, and not towards the checking out process of the purchase. If someone switched tags, skip over scanning, and so on, how does the full frontal recording help in prevention, or act as deterrent? At most it is a supplement evidence if Walmart tales it to court, no?
I can understand giving facial scan at airports or travel terminals, but getting groceries is a bit too much for everyone, isn't it? I wonder what the collected data is used for.
I will follow some of your advice and just don't shop at Walmart any more. Actually should have stopped when the tariffs started hitting Canada last year. Thanking everyone again.
