Credential on file transactions (COF) occur when a cardholder gives express permission to the merchant to store their payment credentials for use on a future purchase.

The COF transaction category introduces 2 transaction types:

- Scheduled COF 
- Unscheduled COF 

These types of transactions also update card brand rules, including merchant disclosure requirements. 

The stored credential transaction category covers all COF transactions, including:

- Cardholder-initiated stored credential transactions - no fixed schedule.
- Industry Specific (delayed, no-show, incremental).

:::::notice{note}
While credential on file integrations are not third party processor specific, if a merchant changes third party processor with already established credentials on file, it is advised that the merchant re-establish those credentials with the new third party processor.
