Amex and Diners maintain their fees

American Express and Diners Club are now charging Australian retailers almost two-and-a-half times the fees charged by their rivals Bankcard, MasterCard and Visa, new Reserve Bank figures show. The figures show the average fee charged to merchants by the three mainstream cards has fallen by almost 50 points under the Reserve's credit card reforms: from 1.46 per cent in September 2003 to 0.97 per cent in the June quarter. But Amex fees have come down far less, while Diners Club fees have barely budged.
