How do I use Apple Pay?

When making purchases at a retailer that accepts Apple Pay as payment, hold your device over the terminal and accept the charge with your fingerprint or passcode when prompted. A subtle vibration and beep lets you know the purchase was successful.
 
Your experience with Apple Pay may vary by merchant. If asked to verify the last 4 digits of a card number give the merchant the last four digits of the Device Account Number instead. The Device Account Number can be found by selecting the ⓘ icon while viewing your card in the Wallet app. You may also be asked to provide a signature or debit card PIN to complete your transaction.
 
You can also use Apple Pay on your iPhone or iPad to make purchases within participating mobile apps. Look for the Apple Pay logo while completing an in-app purchase to use this feature.
