(a) “Security procedure” means a procedure established by agreement of a customer and a receiving bank for the purpose of:
(1) Verifying that a payment order or communication amending or cancelling a payment order is that of the customer; or
(2) Detecting error in the transmission or the content of the payment order or communication.
(b) A “security procedure” may require the use of algorithms or other codes, identifying words or numbers, encryption, callback procedures, or similar security devices.
(c) 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”.
