Standard is for subscriptions and everyday purchases. Premium costs US$ 100 and gives a US$ 100,000 monthly limit and a 0.5% top-up fee instead of 1%: while you have an active Premium card, all your top-ups pay 0.5%. On the top-up fee alone, the higher issue fee pays off after US$ 18,000 topped up. You can start on Standard and issue a Premium card later.
