This bill aims to enhance firearm ownership privacy and restrict the categorization of firearm retailers. It defines key terms related to firearms, ammunition, and payment card transactions, and explicitly prohibits government entities and officials from maintaining lists or registries of privately owned firearms and their owners, except in specific legal circumstances. Additionally, it prevents payment card networks and covered entities from using merchant category codes that would identify firearm retailers separately from other retailers.

The bill also establishes enforcement mechanisms, granting the Attorney General the authority to investigate violations and issue notices to cease such actions. If violations persist, the Attorney General can seek injunctions and impose civil fines of up to one thousand dollars per violation. The bill emphasizes that these remedies are exclusive and provides a defense for entities that can demonstrate compliance with legal requirements regarding merchant category codes.
