Wyoming Second Amendment Financial Privacy Act.

Wyoming's SF 105, the Second Amendment Financial Privacy Act, prohibits credit card processors and financial institutions from using a "firearms code" (a merchant category code identifying firearm purchases) to track or disclose information about firearm and ammunition transactions beyond standard payment processing. The law defines "protected financial information" as records linked to such codes and bans its use for surveillance, discouraging lawful gun purchases, or sharing with government entities without a specific legal requirement. It creates a private right for individuals to file civil lawsuits if their financial privacy is violated and includes exceptions for mandatory financial reporting (e.g., anti-money laundering compliance). The bill directly affects credit card processors, financial institutions, and firearm buyers by preventing the misuse of transaction data for monitoring constitutional rights.
