Amazon has unveiled a new kind of retail store, with no cashiers. Customers at the concept store in Amazon's hometown of Seattle, Washington, can fill their shopping carts and walk out -- with the costs automatically tallied up and billed to their accounts with the US online giant. Amazon Go, which is being tested with Amazon employees and will open to the public next year, is a "checkout-free shopping experience made possible by the same types of technologies used in self-driving cars: computer vision, sensor fusion and deep learning," its webpage said.
