A Supplementary Card is simply a second card that is associated with your X World Wallet account. It can be extremely useful as an emergency card or as a backup.
Some of our customers like having it in their second wallet, and some don't leave the country without it in case they lose their primary card.
With your Supplementary Card, you can earn X World Wallet points at the same rate as your primary card for the X World Wallet Account.
