SEC support for CIE customer-Initiated Entry

Customer-Initiated Entry (or CIE entry) is a credit entry initiated on behalf of, and upon the instruction of, a consumer to transfer funds to a non-consumer Receiver. CIE entries are usually transmitted to a company for payment of funds that the consumer owes to that company and are initiated by the consumer through some type of online banking product or bill payment service provider. With CIEs, funds owed by the consumer are “pushed” to the biller in the form of an ACH credit, as opposed to the biller’s use of a debit application (e.g., PPD, WEB) to “pull” the funds from a customer’s account.
