An ODFI must suspend an Originator that has materially breached the ACH origination agreement or the NACHA Operating Rules to protect the network and limit the ODFI's liability.
5. A consumer's written authorization for a recurring ACH debit must include which essential element?
An authorization for recurring ACH debits must be signed or agreed to by the consumer (Receiver) using a written signature or its electronic equivalent.
6. For which of the following return codes is a Written Statement of Unauthorized Debit not required?
For the return code R-38 (Stop Payment on Source Document), a Written Statement of Unauthorized Debit (WSUD) is not required. A WSUD is typically needed for unauthorized transactions where the consumer claims they did not authorize the debit. However, for an R-38, the consumer has already initiated a stop payment, which serves as sufficient notification to the financial institution.
