Banker paying demand draft whereon endorsement is forged

When a bill payable to order on demand is drawn on a banker, and the banker on whom it is drawn pays the bill in good faith and in the ordinary course of business, it is not incumbent on the banker to show that the endorsement of the payee or any subsequent endorsement was made by or under the authority of the person whose endorsement it purports to be, and the banker is deemed to have paid the bill in due course, although such endorsement has been forged or made without authority.
