Claim

The cardholder states they didn't have the opportunity to choose a currency, or the merchant incorrectly applied currency conversions.

Cause

  • The merchant chooses the wrong currency during transaction processing.
  • Alternatively, the merchant applied dynamic currency conversion without getting the customer's consent.

Steps to Prevention

  • Don't automatically apply dynamic currency conversion without consent from the cardholder.

  • Allow customers to pay in their local currency.
  • Train your sales staff on the correct protocols for handling different currencies.
