You can add rewards or loyalty cards you're currently carrying in your wallet to EUREKA.
Simply go to the top left icon and open the feature drawer. Select Loyalty, then press the “+” button near the top of the screen to add a card. Add a name for the card, enter the card number or scan the barcode on the card.
You can even take a photograph of the card so that it's easier to find it in your Loyalty container. Click on the camera icon in the middle of the EUREKA graphic to take a photo of your card. Keep in mind the cards are currently stored in the order they have been added.
