Amazon Go can make it much easier to get in and out of a store. While currently only a pilot in a small store near Amazon HQ in Seattle, Amazon Go has huge potential to make shopping easier. Each shopper’s activity is tracked by in-store cameras and sensors. Each item that you pick up and put back will be recorded. So in the shopping of Amazon’s Christmas wish all you have to do is enter a store, put the items in your (reusable) bags and walk out. You will be charged to you Amazon account. If you are in the Bay Area you can see Google experimenting with LIDAR in their merchandise beta.
