Apple Pay is the company's first venture into the mobile payments business. Those who own an iPhone 6 or iPhone 6 Plus will be able to make payments at certain retailers just by tapping the phone. Retailers such as Walgreens, McDonalds, Petco, Subway, Macy's, and of course, the Apple Store, will support the service when it launches.
