This legislation aims to prevent the specific identification of firearms retailers through payment processing systems. It prohibits payment card networks and covered entities from requiring or assigning merchant category codes (MCCs) that distinguish firearms retailers from general merchandise or sporting goods retailers, ensuring transactions are categorized similarly to other retail establishments. The bill grants the Attorney General enforcement authority, including establishing a complaint process for alleged violations and conducting investigations. If a violation is determined, the Attorney General must issue a written notice requiring remediation within 30 days, after which an injunction may be sought in federal court. Additionally, the Act explicitly preempts any state or local laws regulating merchant category codes for firearms retailers, establishing a uniform federal standard. It also clarifies that no private right of action is established and requires the Attorney General to submit annual reports to Congress detailing investigations and the Act's effectiveness.
