Apple Pay is Apple’s digital wallet system that lets you make payments using your device. The service is compatible with the iPhone 6 and later.
Setting up Apple Pay is easy. Simply open the Settings app and tap Wallet & Apple Pay. Then tap Add Card and follow the instructions to set up your credit or debit card.
To make payments at compatible contactless payment terminals, first launch Apple Pay with a double-tap of the Home button (or the Side button on newer devices).
Scan your fingerprint or your face, depending on the device you’re using, and then hold your iPhone up to the terminal. Your device will buzz gently and confirm the successful payment on screen.
