Second Amendment Financial Privacy Act amendments.

HB 234 prohibits state and local governments from collecting or maintaining lists of privately owned firearms or their owners using specific merchant codes (like "firearms codes") in payment processing. It also bans payment processors from requiring such codes for firearm retailers or discriminating against them by charging higher fees or refusing transactions based on firearm sales. The bill directly affects firearm retailers, payment processors, and state agencies by restricting how firearm-related transaction data can be handled. Violations could lead to civil actions or criminal penalties, including misdemeanor charges for knowingly violating these provisions.
