A Request for Information (RFI) is a payment inquiry initiated by the cardholder's bank to obtain additional information about a transaction. Merchants are required to submit an evidence package with order information like an invoice, proof of delivery, and any other supporting information related to an order.
RFI's cannot be "won" or "lost", however, if an RFI response is not submitted the liable party will automatically lose any future chargeback filed on that transaction.
Transactions with an RFI can be refunded normally.
