26 iPad and iPhone Tips and Tricks During 2015, thousands of new merchants throughout the United States and the United Kingdom began accepting Apple Pay, and hundreds of banks and financial institutions, including American Express and Discover, now support this payment service. Figure I.10 Using Apple Pay, initiate a debit card, credit card, or store credit card purchase without having to physically present or swipe your credit card. Note If your iOS mobile device gets lost or stolen, simply use the Find My iPhone feature to lock down the device. Your stored credit/debit card details can’t be used by an iPhone thief, because their fingerprint will not be recognized by the Touch ID sensor, and because Apple Pay does not retain your actual credit/ debit card numbers, there’s no need to contact your bank to cancel the cards and have them reissued. Apple Pay works with the Wallet app that comes preinstalled on the iPhone with iOS 9 and makes shopping and paying for purchases at your favorite retail stores, supermarkets, and other businesses a fast and secure process.
