When you add your DukeCard to your Android device, you can tap wherever your physical DukeCard is accepted except Prox readers or Assa Abloy wifi locks. Your Android device must have NFC enabled. Depending upon your device, your screen must be active (awake) but your device does not need to be unlocked. Mobile DukeCard on Android wearables are not supported at this time.
