Apple introduced a new wireless payment system called Apple Pay on Tuesday that comes with every iPhone 6 and 6 plus. You take a picture of your card, and it's added to your Passbook, then you can make a purchase by putting it up to a special point-of-service system and "sign" with the fingerprint sensor in the home button. It uses near-field communication, or NFC, which has been a part of other wireless payment systems in the past — but none of those services have quite gone mainstream. But Apple is rolling out with major partners: Macy's, Bloomingdales, Walgreens, Subway, McDonalds (even drive through), Whole Foods, and of course Apple's own retail stores. Online merchants will also be able to use the system, enabling one-touch buying at places like Target. Whether smaller merchants will find it convenient to add a new machine to their checkout process is another question, and the details of fees and limitations are similarly unknown.
