WASHINGTON—Three senators, including Sen. Amy Klobuchar (D-Minn.) who chairs the Senate Judiciary Committee’s antitrust panel, wrote a letter to Amazon.com Inc to express concern about its palm print recognition system, Klobuchar’s office said Friday.
Amazon began rolling out biometric technology at its Whole Foods stores around Seattle in April, letting shoppers pay for items with a scan of their palm. The system, called Amazon One, lets customers link a credit card to their palm print.
