⚖️ Payment Processing Legislation & Interchange Regulations in United States
Payment processing in the United States is governed by a dual market structure created by the Durbin Amendment (Section 1075 of the Dodd-Frank Act). The Durbin Amendment caps interchange fees on debit cards issued by large banks (assets >$10 billion) at $0.21 + 0.05% + $0.01 for fraud prevention. However, unregulated credit card interchange fees remain uncapped, ranging from 1.5% for standard consumer cards to 2.95% for premium rewards and corporate cards. As a result, US payment processors charge flat-rate merchants a default rate of 2.6% to 2.9% + $0.30 per transaction.
