Dash Cart: Amazon's smart shopping cart knows what you're getting, displays your subtotal

Amazon has created a smart shopping cart that knows what you're selecting and can charge you for it without a cashier. It's called the "Amazon Dash Cart" and the idea is to make "a quick grocery trip even quicker by allowing you to skip the checkout line," the e-commerce giant said in a post on Tuesday. The Dash Cart largely looks like a typical shopping cart, only bulkier at the bottom. Patrons will use their Amazon account's unique QR code to sign-in to the cart, according to a video the company posted on its website. Then you add your shopping bags to the cart and proceed to shop around the store.
