How do I make payment in stores with an Apple Watch?
With an Apple Watch you double-click the side button and hold the display up to the contactless reader to authorise a payment – whilst wearing the Apple Watch.
Please note: the Apple Watch NFC feature has to be activated before Apple Pay will work. When you strap your Apple Watch to your wrist you will be prompted to enter the device passcode. This will enable Apple Pay. If the Apple Watch is removed from your wrist, so skin contact is lost, Wrist Detect detects that skin contact has been lost and Apple Pay and the NFC feature are deactivated.
