Credit card transactions; prohibiting issuers from charging certain fees; prohibiting issuers from penalizing merchants; requiring issuer to disclose information. Effective date.

SB 2102 prohibits large credit card issuers ($85 billion+ in assets) and payment networks from colluding to set credit card transaction fees or penalizing merchants who offer discounts for cash, debit, or gift card payments. It requires issuers to clearly disclose swipe fees (including interchange and assessment fees) to cardholders on monthly statements and payment networks to provide merchants with detailed fee breakdowns within 45 days of each transaction. The law empowers Oklahoma’s Attorney General to enforce these rules, impose civil penalties up to $30 million for violations, and file lawsuits against noncompliant entities. The bill takes effect November 1, 2026, directly affecting major financial institutions, payment networks, merchants, and cardholders in Oklahoma.
