RDR — Rapid Dispute Resolution
Mastercard program. Enrollment is usually through the acquirer or a Verifi / reseller seat, not a brand-level checkbox.
Issuer starts a Mastercard dispute that hits your RDR rules (amount, reason, MCC, etc.). The refund posts instead of a chargeback.
This is before a primary chargeback. Most acquirer programs keep RDR out of the primary CB ratio — confirm the contract. It is still a refund plus a per-case fee.
The merchant pre-agrees to automatically refund a Mastercard dispute that matches rules, before it becomes a chargeback.
Per-case fee set by the acquirer or reseller. Mastercard does not publish a retail price. You also lose the sale.
Per MID, on Mastercard volume. Rules (amount caps, reason codes, shipped vs not) are the job. Over-broad rules refund winners.
A MID without RDR still takes the chargeback. Enrolling “the brand” does nothing. Map rules per merchant account. Not Ethoca (alerts you act on). Not Visa CDRN. Not 3DS. Not a representment product.
Use this reference when you are deciding whether RDR belongs on this Mastercard MID, what the per-case fee plus refund costs versus representment, and whether the acquirer drops those cases out of the primary ratio.
