The purpose of the standard is to stop merchants from charging a customer more than what it costs merchants to accept a type of card for a transaction – known as ‘Cost of Acceptance’. Your acceptable costs are limited to the fees you pay us and certain other observable costs paid to third parties if the costs are directly related to accepting particular types of cards.
