(A) If an accepted payment order is not an authorized order of a customer identified as sender under division (A) of section 1304.57 of the Revised Code, but is effective as an order of the customer under division (B) of that section, both of the following apply:
(1) By express written agreement, the receiving bank may limit the extent to which it is entitled to enforce or retain payment of the payment order.
(2) The receiving bank may not enforce or retain payment of the payment order if the customer proves that the order was not caused, directly or indirectly, by either of the following:
(a) A person entrusted at any time with duties to act for the customer with respect to payment orders or the security procedure;
(b) A person who obtained access to transmitting facilities of the customer or who obtained, from a source controlled by the customer and without authority of the receiving bank, information facilitating breach of the security procedure, regardless of how the information was obtained or whether the customer was at fault. As used in division (A)(2)(b) of this section, "information" includes any access device, computer software, or the like.
(B) This section applies to amendments of payment orders to the same extent it applies to payment orders.
