To keep your Iberia Plus card in your Wallet or Passbook, you first need to download the Iberia app. Once you've done that, follow these steps:
Inside the Iberia app, register with your card number or your email and password (if you don't have one or can't remember it, we'll send a new one to your email address).
Next, go to “My Iberia Plus” (top right-hand corner).
Select 'Download card', just below the image, and your card will be added to your smartphone. Remember, for Android you need to install an app that stores pkpass files.
Now close the Iberia app and open the Wallet app (or other installed app). You'll see your card there and will be to show it to any partner who can read the QR code.
If your Iberia Plus level changes, you will need to download your new card again from your profile in the app.
