Guns bought through credit cards in the US will now be trackable

A new ISO-approved measure will also allow sharing of suspicious purchases with law enforcement

Credit card purchases of firearms in the US can now be tracked and purchases deemed suspicious can even be shared with law enforcement, according to a new measure approved by an organization that sets parameters for business transactions.

The International Organization for Standardization (ISO) voted in favor of creating a merchant code for firearms stores, according to Reuters.
