“Security procedure” means a procedure established by agreement of a customer and a receiving bank for the purpose of (i) verifying that a payment order or communication amending or cancelling a payment order is that of the customer, or (ii) detecting error in the transmission or the content of the payment order or communication.  A security procedure may require the use of algorithms or other codes, identifying words or numbers, encryption, call-back procedures, or similar security devices.  Comparison of a signature on a payment order or communication with an authorized specimen signature of the customer is not by itself a security procedure. (1993, c. 157, s. 1.)
