iPhone 6 and Apple Pay
Apple released the iPhone 6 with larger screens and launched Apple Pay, beginning the transformation of the iPhone into a digital wallet.
On September 19, 2014, Apple released the iPhone 6 and iPhone 6 Plus — the first iPhones with screens larger than 4 inches (4.7" and 5.5" respectively). The larger displays reflected user demand and finally matched competitor screen sizes. More significantly, Apple launched Apple Pay alongside the iPhone 6, using NFC (Near Field Communication) and Touch ID to enable contactless payments. Users could add credit cards and pay by holding their phone near a terminal. Apple Pay accelerated the shift toward cashless commerce and mobile payments globally. The iPhone 6 became Apple's best-selling model ever, with over 222 million units sold.
