Financial institutions; creating the Oklahoma Second Amendment Financial Privacy Act; authorizing certain investigations by Attorney General. Effective date.

SB 16, the Oklahoma Second Amendment Financial Privacy Act, prohibits financial institutions from using payment card transaction codes to identify firearm retailers or firearm-related purchases. It specifically bans payment networks and covered entities (like banks processing payments) from assigning or requiring merchant category codes that distinguish firearm retailers from other businesses. The law also prevents government entities from maintaining lists of privately owned firearms or their owners. The Oklahoma Attorney General can investigate violations and require entities to stop the prohibited practices within 30 days.
