For Apple Pay users, the iPhone X, X S X S Max or X R will be an adaptation. Gone are the days when you could put your finger on the Home button and hold your device within reach of a contactless reader. Without Touch ID on the iPhone X this is not possible. But do not worry, Face ID is here.
Apple's New Security Feature Replacing Touch ID on the iPhone X X S S  Max and X R provide authentication that uses the Touch ID normally, including Apple Pay. Whether you've just bought a new iPhone and you do not know how to use Apple Pay and Face ID, or if you're just interested in how it works, I'll explain it below.
To use Apple Pay on the iPhone X, X S X S Max, and X R unlock the device, then double Click the Page button to bring up the Apple Pay app. Once you're there, you'll need to actively view your iPhone X to verify your identity with Face ID. So open your eyes and take off your sunglasses. You'll know when your device detected it when the small blue icon in the middle of the screen changes from Face ID to Hold Near Reader.
