Visa, Mastercard, AmEx to categorize gun store sales separately
Payment processor Visa announced Saturday its plans to separately categorize gun shop sales, joining Mastercard and American Express, which have already said they would categorize purchases at firearm stores.
Visa said it would apply the International Organization for Standardization’s new merchant code to gun shop sales. The new IOS code was announced on Friday. Previously, gun store sales were labeled as "general merchandise."
