Apple Pay is an innovative payment method allowing customers to make secure purchases using an Apple device. The service is compatible with the iPhone 6 and newer models as well as the iPad Air 2, iPad Pro, and the Apple Watch.
Apple Pay is simple to use and effortless, allowing for quick payments as checkout is completed with just a single touch. It is very similar to contactless payments already used in many countries, with the addition of two-factor authentication via Touch ID, Face ID, PIN or passcode.
