The first iOS app to receive Apple Pay integration is of course one of Apple’s very own. The official Apple Store app has been updated with “easy one-touch checkout with Apple Pay” on Touch ID-equipped iOS devices.
Using Apple Pay requires iOS 8.1 and a credit or debit card on file in Passbook. While NFC in the iPhone 6 and 6 Plus is required for making Apple Pay transactions at physical stores, online payments only require Touch ID. That means you can use Apple Pay through apps on the iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air 2, and iPad mini 3.
Several other apps should be updated with Apple Pay support any minute now, including Uber, Lyft, Airbnb, Groupon, Instacart, OpenTable, MLB.com, Panera Bread, Target, and the Disney Store app.
