How cashierless stores and carts in Amazon, Whole Foods, and Kroger work, helping shoppers skip the checkout line

Retail giants have increasingly leveraged in-store technology that allows customers to buy products without waiting in line for the cashier. By marrying advancements in artificial intelligence and computer vision, cameras and sensors, and deep learning algorithms, these locations permit visitors to shop by simply picking up goods or placing products in their carts, nixing the need for a cash register altogether.

Amazon Go stores began opening to the public in 2018.
