That's very easy. To link a card to an account, you need to link the email address you're already using for Joyn, to that card.
It's very easy to do with the Joyn smartphone app:
- Tap 'Tap to scan QR code'.
- Scan your card's QR code.
- The card is now linked to your account!
Don't have a smartphone?
- Go to https://my.joyn.be/card-registration
- Enter your card number and the email address that is linked to your Joyn account.
- Choose 'Confirm'.
- Open the email 'Enjoy your new Joyn card' and click the 'Link your new card' button.
- The card is now linked to your account!
