As you know American Express is not accepted all over the place and that can be frustrating. Well soon you will be able to link your AMEX card to the new Imagine Curve Mastercard. It's really smart actually, you connect your American Express card to your Curve Card and select it when a retailer says no to AMEX. As the Curve Card is connected to your AMEX card it instantly recharges.
This feature is in beta testing with the Curve Card and should soon be available for all to use.
More details to follow when they become available.
