Heartland Payment Systems has agreed to pay up to $5 million to Discover Financial Services in relation to the data breach that hit the processor in 2008, marking its final settlement with all leading card brands over the intrusion.
Heartland revealed last January that malicious software in its processing system had been found, potentially compromising the card data of millions of people.
The $5 million settlement with Discover follows a $41.4 million pay-out to MasterCard, a $60 million bill from Visa and a $3.6 million deal with American Express. In Dember last year the embattled processor also agreed to pay up to $2.4 million to settle a consumer cardholder class action suit
Announcing the latest agreement, Bob Carr, Heartland's chairman and chief executive officer, says: "This settlement marks our final agreement with a card brand related to the intrusion."
