Nashville International Airport’s Hudson Nonstop concession shop is the latest location to add Amazon.com Inc. “Just Walk Out” technology, which allows customers to bypass checkout when purchasing items. Shoppers swipe a credit card or wave their palm above an Amazon One device when they enter, and leave with their items when they’re done shopping. Amazon One links a shopper’s palm to a payment method. Just Walk Out is also available in Houston’s Minute Maid Park, at New York’s LaGuardia Airport and other locations. Amazon stock has slumped 37.8% for the year to date.
