Requires use of merchant category codes for purchases of firearms and ammunition.

This bill requires payment card networks (like Visa or Mastercard) to make available a specific merchant category code for firearm and ammunition businesses by July 2026. It then mandates that payment processors (merchant acquirers) assign this code to firearms merchants - defined as New Jersey retail dealers where most sales come from firearms, accessories, or ammo - starting May 2027. The Attorney General enforces compliance, with violations carrying a $10,000 penalty per incident, though processors get 30 days to fix issues before penalties apply. The law aims to standardize transaction tracking for firearm-related purchases without restricting sales.
