You take the item(s) back to the retailer as normal. Some retailers will be able to offer refunds back to the device from which the original payment was made, while other may have to refund the plastic card.
If the retailer is able to refund the device used to make the original purchase, you:
- Select the card they want to be refunded within the Wallet app
- Hold the device above or near the contactless reader and authorize the refund using Touch ID, Facial Recognition or the device passcode; or
- Hold the Apple Watch display up to the contactless reader and double-click the side button to authorize the refund
You may need to provide the last four digits of the Device Account Number to the retailer. This can be found by opening the Wallet App and tapping the (i) symbol in the bottom right corner and then scrolling down to find Device Account Number.
