Are you willing to let Amazon read your palm and keep a record of that image? If so, you’ll soon be zipping through the checkout line at Whole Foods. The retail behemoth is now offering hand scanners that link to your profile, store your credit card and let you bypass the cash registers with little more than a high five. The technology is already in place at most Whole Foods stores, as well as Amazonbooks on Bethesda Row and the Amazon 4-Star store at Westfield Montgomery mall. It’s also on the way to at Amazon’s new grocery stores, including the one that’s under construction on Shady Grove Road.
