This provides access to some pretty good benefits if you're traveling.

Purchase Protection:
Enjoy up to 180 consecutive days of free worldwide Purchase Protection Insurance covering you against theft and accidental damage on eligible purchases.

I'm guessing this will be a good option compared to a Wise card, with the benefits that you get. It's good to have options.
