Amazon is getting into the home delivery and grocery business. Walmart is providing door-to-fridge deliveries via smart doors & web cams. I'm sure Amazon is looking to provide the same play. With their video AI, they can sell a fridge that scans the contents and figures out a pick list for you automatically, order it, and have it delivered to your home. Delivery person enters a one-time PIN to get in. Webcam records their visit. Delivery person puts all the groceries in the refrigerator and leaves. You could also have other packages, appliances delivered and installed, while you are away.
This is the future of home delivery & shopping.
