Ensure that you download the latest “Mastercard Travel Pass” app. On the app, Tap on the Mastercard Travel Pass app, tap on "Sign Up" and Register your supplementary card.
Make at least one international transaction worth $1 (or the local currency equivalent), using your supplementary card registered on the Mastercard Travel Pass app, at a point of sale or online (e-commerce).
