Directs the Federal Trade Commission (FTC) to prescribe regulations to: (1) ensure that the rules, terms, and conditions to which a merchant or consumer is subject under an agreement with an electronic payment system network are neither unfair nor deceptive to consumers and merchants, nor anticompetitive; (2) prohibit any unfair or deceptive act or practice or anticompetitive act or practice that may result from such rule, term, or condition; and (3) regularly review such rules, terms, and conditions.

Directs the Board of Governors of the Federal Reserve System to collect and disseminate to the public: (1) complete information on fees charged by each electronic payment system network in connection with consumer-initiated transactions; and (2) the rules, terms, and conditions to which a merchant or a consumer is subject under an agreement with an electronic payment system network for transactions using payment cards.
