Amazon plans to bring cashierless technology to Whole Foods starting next year. The system is called Just Walk Out and allows shoppers to shop in-store without going through traditional checkout counters. Instead, technology relies on cameras, artificial intelligence algorithms and mobile apps to track and record what consumers buy off the shelf. All items will then be charged to the buyer’s credit card as soon as they leave the store. 3,000 before $7,500 in federal incentives.
