Bill Summary · SB 1143

Legislative bill overview

SB 1143 would prohibit payment processors and merchant category codes from being used to restrict or track firearm and ammunition transactions. The bill prevents financial institutions and payment processors from implementing special monitoring or categorization systems for gun-related purchases that differ from other retail transactions.

Why is this important

Payment processors and some financial institutions have voluntarily implemented special merchant codes for gun dealers to enable transaction monitoring for fraud detection or regulatory compliance. This bill addresses concerns that such systems could be used to create de facto registries of gun purchases or to discriminate against lawful firearms commerce, while critics worry removing oversight mechanisms could enable illegal weapons trafficking.

Potential points of contention

  • Second Amendment vs. financial regulation: Whether merchant code restrictions represent unconstitutional infringement on gun rights or legitimate financial oversight of commerce
  • De facto gun registry concerns: Disagreement over whether tracking firearm purchases through payment data constitutes government overreach or standard commercial practice
  • Enforcement of federal law: Tension between state prohibition of monitoring and federal ATF requirements for regulated dealers' record-keeping and suspicious activity reporting
  • Private business autonomy: Whether states can mandate how private payment processors must or cannot categorize transactions
