  RFID tags have a lot of problems among them that unless you get every manufacturer on board for labeling all the products in your store you're going to have to spend a lot of time labeling products before shelving. It's also a continuous cost per item either from the manufacturer or from the in house labeling process where a static system like Amazon Go can track without adding a per item cost. It's also not good enough to be the only system in a store because it's easy to block the signal using a foil lined bag so the store will already need another system at least as good as RFID at tracking things coming off the shelves. As for what they look for that's the secret sauce but there's a few things that are pretty clear from descriptions. They seem to be using mainly (only?) cameras for the identification. Luckily branding is pretty prominent so they have a pretty convenient thing for their item labeling to look for in the feeds. For cart shopping there's some simple things like tracking people with their faces from when they enter then adding items to their cart when they move an item outside a defined shelf region.
