Protecting the Second Amendment in Financial Services Act

This bill prohibits financial institutions and payment processors from using specific merchant category codes that separately identify businesses selling firearms or ammunition. It directly affects banks, credit card networks, and payment processors that handle transactions for firearm retailers. The key provision amends the Truth in Lending Act to require these covered entities to treat firearm merchants the same as other businesses for transaction categorization purposes. The law does not change gun ownership laws or restrict firearm sales, only addressing how financial transactions are classified.
