I have so many questions. How does it differentiate customers? Like say I'm standing in line just off to the side behind someone buying a few big ticket items, when the face scan happens how will it know which face to charge? Same question for a couple people checking out together. Will I have to take my hat and sunglasses off to check out or does it use other technologies to build face maps like lidar? What if I got a broken nose or fractured orbital, can I just not buy things? What about beards, if a guy scans his face initially with a beard and shaves it, how will the system respond? Is there an upper limit on purchases made this way like there is with tap to pay? What will it do about age verified products like tobacco or alcohol?
I would bet money they didn't test for any of that and if they did it would be within very narrow parameters.
