Stored Credential Overview

Stored Credential Transactions relate to when a Cardholder’s payment credentials (e.g. a PAN and Expiry Date) are stored by the Merchant system for seamless use in subsequent transactions. Note: It is still prohibited to store a Cardholder’s CVV2/CSC.

A card scheme initiative now means that Merchants and their Acquirers are mandated state the intention for a transaction where a stored credential has been used. Subsequent transactions that are initiated by the Merchant typically do not carry a form of cardholder verification, such as CVV2/CSC, and so would result in a higher chance of the Issuing bank declining the transaction. Indicating the intended use of the stored credential now allows Issuing banks to better asses the risk on the transaction, resulting in a higher chance of approval.

Stored Credential Transactions can be broken down into 'CoF' (Card/Credential-on-File) and 'MIT' (Merchant Initiated Transactions)
