Amazon may offer hand recognition payments to other stores
Amazon's rumored hand recognition payment tech might be useful beyond paying for produce at Whole Foods. Wall Street Journal sources say the company is developing hand-based checkout terminals that it would sell to "coffee shops, fast-food restaurants" and other stores that tend to have repeat customers, not just Whole Foods. It's also clearer as to how the technology might work. The system would reportedly start by linking your payment card to your hand, asking you to insert your old-school plastic and scan your hand before you could pay using your hand alone.
