Home Depot filed an antitrust lawsuit in federal court this week against credit card giants Visa and MasterCard.
Among a bevy of grievances, the do-it-yourself retailer posits that Visa and MasterCard sought to block the adoption of chip-and-PIN on credit card transactions following the migration to EMV payment security standards last October. Additionally, the retailer argues that chip-and-signature is simply less secure than its chip-and-PIN counterpart.
