Money travel card

We have been regular travellers abroad and have access to both a JaJa credit card as said no foreign fee transaction, but also a Halifax Clarity credit card, no foreign fee transaction or fee for cash withdrawal, just pay interest from day taken so we pay the amount off in a couple days and pay pennies in interest, found it the best way to get cash out worldwide. We prefer the Halifax as website and service is better than JaJa.
