 You take your ID, you put it in the machine. It's a 2,000-pound, big, white, sleek-looking vending machine that's right in the front of the grocery store. And the machine scans your ID, checks that you're 21, and then actually does facial recognition. So you have to stand in front, like if you were at TSA or getting clear, scan your face, and they double-check that your face matches your ID. So that's the extent of the check.
