It's called near field communications, and Google thinks it's the next step in moving the world into a cashless society. Preparing for a trial run in New York and San Francisco, Google will be providing businesses with prototype Veriphone NFC wireless terminals which will enable customers to make purchases using their smartphones. In addition, NFC supported smartphones will be able to redeem digital coupons, update gift card balances, use loyalty cards and other retail features designed for retail checkout. And it's not some minor experiment either. Google is reported to be paying for the installation of thousands of NFC-enabled terminals at retail locations all across both cities.
