Wyoming second amendment financial privacy act.

Wyoming's SF 171, the "Second Amendment Financial Privacy Act," prohibits financial institutions from using or disclosing payment card transaction data to identify lawful firearm or ammunition purchases. It bans assigning "firearms codes" (like special merchant category codes) that would allow banks or payment networks to track gun-related transactions, preventing such data from being shared with government entities. The law defines "protected financial information" as payment records linked to firearm codes and allows civil lawsuits if the ban is violated. It directly affects banks, payment processors, and gun retailers by restricting how they handle transaction data related to firearm sales within Wyoming.
