Part 2 - Issue and Acceptance of Payment Order
§ 47-4A-201. Security Procedure

Security procedure” means a procedure established by agreement of a customer and a receiving bank for the purpose of:
Verifying that a payment order or communication amending or cancelling a payment order is that of the customer; or
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, callback 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.
