How do I pay with Apple Pay on apps?

  1. Select Apple Pay as a payment method.
  2. Check that the information is correct. If you wish to change it, select the button next to the card. 
  3. If needed, add delivery and contact information to your iPhone or iPad. Apple Pay will save this information, and you won’t have to add it next time. 
  4. Confirm the payment with Touch ID, Face ID or your PIN code on your iPhone or iPad. If you’re paying with Apple Watch, press the side button twice.
