Most people see the eye scanner stuff in Minority Report and recoil in horror. I see it and I'm like "hell yeah. Let me buy shit without doing anything but grabbing the thing and leaving."
To be entirely fair, the glass doors are terrible for refrigeration efficiency because the glass is far less insulated than the door with the screen is. It might actually save electricity by powering a screen that shows a picture of the product over a insulated door than just having a glass door.
This implementation looks ugly as heck of course but if there's a big enough energy efficiency gain I suppose it might be worth the trade off
Still not as insulating as a thick door with the manufacturer's choice of insulation material. Double/triple pane glass is far better than a single pane window but a window is still a window
