Amazon is testing scanners that can identify a human hand to use as a payment method for in-store purchases. The company plans to introduce "Orville" to some Whole Foods stores by the beginning of 2020, and later expand it to all locations in the United States. Employees at Amazon's New York offices are said to be using the technology to buy items such as sodas, chips, granola bars and phone chargers from specially equipped vending machines. The high-tech sensors used in the pilot use computer vision and depth geometry.
