Subtitle 2 - Issue and Acceptance of Payment Order
Section 4A-201 - Security Procedure

(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”.
