TORONTO, January 21, 2009 – In response to a security breach involving payments processor Heartland Payment Systems, MasterCard is monitoring developments and has notified issuers of cards that are believed to have been put at risk. These notifications enable issuers to monitor accounts believed to have an elevated level of risk and take such other action as an issuer may believe necessary or appropriate, such as the reissuance of accounts.
MasterCard is concerned whenever there is any possibility that cardholders could be inconvenienced and endeavors to take steps intended to help safeguard account information. If cardholders are concerned about their individual account, they should contact their issuing financial institution. In many regions around the world, including the United States, cardholders are protected by the so-called MasterCard Zero Liability rules. In most instances a cardholder will not be liable for unauthorized transactions on his or her account.
Protecting cardholders by preventing fraud and safeguarding financial information is a top priority at MasterCard.
