And you won't have to wait on line to pay for the items in your cart.

Dread your weekly shopping trip? Could the checkout line have something to do with that? If so, you’ll love the concept behind a new retail store announced by Amazon in an online video today.

The new grocery store, called Amazon Go, differs from your regular supermarket in a big way—rather than wait on a checkout line, customers will use an app called Amazon Go to add items to a digital shopping cart. When shoppers first arrive they scan a QR code, gather items, and simply walk out of the store with their purchases. Once a customer has left the store, Amazon will charge the credit card associated with the customer's account based on what they bought.

But how does that work exactly? Amazon says it has developed a machine-learning technology that uses computer vision and sensors to automatically detect what items have been added to your cart. The technology also knows if you put something back—or even if you simply looked at something, but never put it in your cart.

The first Amazon Go location, set to open in Seattle early next year, will sell grocery staples (like bread and milk), ready-made food, snacks, and other products you'd find at your local supermarket.

This isn’t the first brick-and-mortar store from Amazon, which has opened a number of bookstores throughout the United States.
