Amazon testing tech that uses the shape and size of customers' hands to check out at Whole Foods

By simply waving one's hand in front of a scanner, customers may soon be able to cash out at the health-centric grocery chain, Whole Foods, as soon as next year. Amazon, which purchased Whole Foods in 2017 for more than $13 billion, is reportedly developing computer vision technology that can judge the shape and size of customers' hands to create a unique handprint, according to sources cited by the New York Post. That data would then be linked to patrons' bank information, meaning customers would be able to waive their hands in front of scanner and complete the transaction in under a second. Whole Food will reportedly begin testing a technology that reads customers hand size and shape to make payments. Patrons will be able to wave their hands in front of a sensors and complete the transaction in under a second.
