There have been several lawsuits against credit card issuers for “hidden” international conversion charges. Prominent cases include:

Schwartz v. Visa International Corp. No. 822404-4

In 1996 a California State superior court judge ruled that although the 1 percent fee charged by Visa was reasonable, the practice of not disclosing the fee to cardholders in monthly statements was unfair and in violation of state law. Although fee information had been disclosed in the cardholder agreement, it was not itemized on the monthly statement. As a result of the ruling Visa and Mastercard were required to refund foreign conversion fees paid by California cardholders. (More Information.)

Class Action Against AmericanExpress
In 2003, a class action lawsuit was filed against AmericanExpress. Like the Schwartz case, the lawsuit focused on the fact that AmericanExpress did not itemize or disclose the fees on monthly credit card statements.
