I have to hand it to Amazon. They keep changing the game. The latest news is that they plan to launch a chain of bricks and mortar supermarkets, Amazon Go, that are devoid of checkout lines and clerks. Smaller than a 7-Eleven convenience store (they are about 1800 square feet), the stores will allow you to walk in, make a purchase, walk out and have the items you picked billed to you via your credit card.
That is, indeed, pretty convenient. Here is how it works. You will, of course, need an app. Once you have it, you scan your QR code when you walk in the door. Each time you put an item in your basket it is added to your bill. Never fear, the system also knows when you put a product back. When you are finished you simply walk out the door.
What are the implications?
