What is Apple Pay and how does it work?
To use Apple Pay for purchases in-store, you must first add
your eligible debit or credit card(s) on your device using the Wallet app.
To pay using Touch ID, hold your device near the contactless
reader. Then, place your finger on “Touch ID” and hold the iPhone near the
reader until you see “Done” and a checkmark on your screen which indicates that
your payment is complete. If “Touch ID” doesn’t work, or you do not have it
enabled, you will need to enter your device passcode.
To pay using Face ID, double-click the side button. Glance
at your iPhone to authenticate with Face ID. Hold your device near the
contactless reader until you see “Done” and a checkmark on the screen which
indicates that your payment is complete.
To use Apple Pay for purchases within
participating merchant apps (or in-app), you must first add your eligible card
by going to “Settings” opening “Wallet & Apple Pay” and selecting “Add
Credit or Debit Card.”
