The Durbin Amendment,  also known as Regulation II,  is a provision of United States Federal Law, 15 U.S.C. § 1693o-2, that requires the Federal Reserve to limit fees charged for debit card processing. Prior to the Durbin Amendment, debit card swipe fees were previously unregulated and averaged about .44 cents per transaction. The Durbin Amendment also gave the Federal Reserve the power to regulate debit card interchange fees, and on December 16, 2010, the Fed proposed a maximum interchange fee of .12 cents per debit card transaction.
