Where cards are stored on Android devices
Idenge digital cards and passes are stored within the GPay APP (Google Pay).
Android Google Pay (GPay) is an App pre-installed on the new Android devices and therefore you do not have to download it. In older devices when clicking the link on the Idenge card, it is automatically redirected to the Play Store for the GPay download.
Your Idenge cards are stored next to the payment cards that you have installed and along with other cards for everyday use such as the boarding cards of the different airlines.
