"Amazon Abandons 'Just Walk Out' Tech in Grocery Stores for Smart Carts"

Amazon is replacing its "Just Walk Out" technology at U.S. grocery stores with smart shopping carts, while leaving it in the U.K. This move signifies a shift in the company's cashier-free grocery ambitions, as it grapples with the challenges of automating the supermarket experience. The smart shopping cart, essentially a self-checkout on wheels, is now being rolled out to a handful of Whole Foods stores, offering real-time updates to the receipt and potential advertising opportunities. However, the success of this new technology depends on shoppers' learning curve and the complexity of introducing new tech in the grocery industry.
