Visa and MasterCard now charge a cross border transaction fee even when no currency conversion occurs. This relatively new fee - “cross border transaction fee” (MC) or “International Service Assessment (ISA) fee” (Visa) – was initiated by Visa and MC to ‘fight’ usage of the international credit card processing network when no currency conversion occurs.
