January 23 - Amazon Go

Amazon Go is making your grocery shopping quick and easy. You have to download the store's smartphone app to enter the 1,800 square foot minimarket, and then you can go shopping for your food.

The thing is, there are no cashiers. Once you put an item in your bag, your Amazon account automatically charges you for the product. If you put it back, your account will remove it from your virtual shopping cart. So as soon as your finished picking up the foods you want, you just walk out the door.
