Cook also noted that Apple has been working hard on the partnerships for Apple Pay, and has added support for 500 new banks in the 5 weeks since Apple Pay was first announced. Apple has also expanded the retail partnerships for Apple Pay, and Tim Cook was careful to remind everyone that Apple Pay is not just a tap-to-pay option, but will be used online through a number of partners, like Airbnb, OpenTable, StubHub, and more. It seems that Cook may have been reading many of the articles that note the Apple Pay "partners" have had NFC systems in stores for quite a while now.
Apple Pay will start going on Monday, but you will need to get the iOS 8.1 update before it will work on your new iPhone 6 or 6 Plus. So, don't get angry at Target if tap-to-pay doesn't work, if you haven't updated your phone beforehand.
