This is an interesting one: you take a photo of your Credit Card and add it to Apple Pay. Your bank verifies it, the card’s added to Passbook and you can access it for purchasing, using either your iPhone 6 or 6 plus.
Once you’re ready to purchase, simply open your card Passbook, tap your phone at an NFC (near-field communications) payment terminal and you’re nearly there. The Touch ID sensor confirms your finger print, and that’s all there is to it.
Several retailers are already on the same boat as Apple Pay, including Nike and Bloomingdale’s. However, Apple is banking on Apple Pay usage to come mostly in the form of in-app purchases from titles such as AirBnB and Instacart; since iPhone 5s and newer iPads also have Touch ID, users can enjoy in-app Apple Pay purchases.
