Google is nearing a trial of an NFC (near field communication) wireless payment system of its own, tipsters claimed Tuesday. A test in New York and San Francisco would see VeriFone supply cash registers with NFC built-in so that owners of NFC-equipped phones like Google's own Nexus S could pay just by bringing the device close to the register. Bloomberg was told it might go beyond just payment to include gift cards, loyalty programs and coupons.
