CIT vs. MIT: How Credentials on File Work for Recurring Payments
A customer signs up for a monthly service, saves a card and successfully completes the first payment. Thirty days later, the business submits the next recurring payment using the same stored credential. To the merchant, it may look like the same payment happening again. To the issuer, it is a different transaction with different requirements. The first payment is a customer-initiated transaction, or CIT. The subsequent recurring payment is a merchant-initiated transaction, or MIT, made under the agreement established during the original purchase.
