A chargeback prevention tool developed by Verifi as an upgrade to the Chargeback Dispute Resolution Network (CDRN) . Driven by a rule-based engine, merchants can define in advance what types of disputes they would prefer to accept and refund automatically. This way, when the dispute rules are matched, the RDR will communicate with the acquirer to automatically debit the merchant’s account and issue a refund, thus preventing the dispute from becoming a chargeback.
