(Reuters) -Discover Financial Services, a provider of credit cards, told Reuters it will allow its network to track purchases at gun retailers come April, making it the first among its peers to publicly give a date for moving ahead with the initiative, which is aimed at helping authorities probe gun-related crimes.
Discover's announcement came after the International Organization for Standardization (ISO), which decides on the classification of merchant categories used by payment cards, approved in September the launch of a dedicated code for gun retailers.
Proponents of the move, including gun control activists and Democratic politicians, say it will allow financial institutions to better assist authorities in investigating crimes involving gun violence in the United States.
