Visa Inc., Mastercard Inc. and American Express Co. will take steps to implement a new merchant code that could improve tracking of firearm purchases. 

The moves by the largest US credit-card companies come a day after the International Organization for Standardization approved a new merchant category code for gun and ammunition stores to use when processing transactions. The approval follows a campaign by Amalgamated Bank, New York city and state officials, and the California’s teachers’ pension fund for the new code.
