Using Apple Pay is easy no matter what device you use. To pay in shops, there is no need to wake your device. Simply hold your phone near the contactless reader with your finger on touch ID. Or double click the Home button when the phone is locked to open up your wallet and choose which card you wish to use. If you’ve added multiple cards to your Wallet, they will appear in a stack. The one at the bottom of this stack is your default card, and it’s this one that will make the payment. When you want to change it, just tap it and drag upwards and a new card will take its place as your default card.
If you’re paying in app with your iPhone or iPad, select Apple Pay, then put your finger on Touch ID.
With the Apple Watch, double tap the side button to bring up the card logo, then hold the watch display to the contactless reader.
When your payment has been authorised there’ll be a small vibration and a beep to confirm.
