Mastercard, Visa Push Joint Rules to Combat Payment Fraud

Mastercard and Visa operate the card networks linking issuers, acquiring banks and merchants across global commerce. Their proposed rules would place greater responsibility on merchants and banking partners to identify, stop and manage suspicious transactions together. The initiative matters because payment scams can exploit gaps between institutions, while coordinated controls could strengthen network-wide defenses and reduce the risk that fraud is handled by only one participant.

Mastercard is moving to bolster its scam defenses through new requirements intended to deepen cooperation between merchants and their partner banks, while Visa is also pursuing tighter joint safeguards. The available report does not specify a formal announcement date, implementation deadline, financial threshold, quantified fraud-reduction target or penalties for noncompliance. Those details will determine how broadly the measures apply and what operational changes banks and merchants must make.
