An originator of a check other than a payor shall not be required to pay by certified or guaranteed check, unless an insufficient funds check is received and the provisions of this section have been followed.

2. In addition to any fees imposed pursuant to section 454.425, the payment center, when authorized by the division, or the state may charge a fee not to exceed twenty-five dollars for processing an insufficient funds check as a reimbursement for the costs of processing such check, and may issue a notice to the originator of any such check that no further checks will be accepted unless the check is certified or guaranteed for payment.
