Rules impacting processors and retailers

You also should be aware that Mastercard rules and other standards change from time to time. While we always strive to keep the documents on this Web site up to date, it's possible that they will not always be absolutely current in all regards. In the event of any discrepancy between the documents found at this Web site and those rules and standards Mastercard deems to be the official rules and standards, the official rules and standards will apply.
