When you add your DukeCard to your Apple device, you can tap wherever your physical DukeCard is accepted. Simply hold the top of your device to the reader. You can have any combination of (1) physical card, (1) DukeCard on your iPhone, and (1) DukeCard on your Apple Watch active at any time. Your iPhone or Apple Watch must be turned on, but it doesn’t have to be connected to a network. You don’t need to unlock your device or open an app at the reader.
