  • Method and system for non-contact automated verification of the correctness of the identity of an item having an associated primary identifier
    Publication number: 20030057276
    Abstract: A method for automated identification of the correctness of the identity of an item which has an associated primary identifier of a first machine readable type includes associating a separate, secondary identifier with the item prior to the time that verification of the correctness of the item is sought, the secondary identifier being of a second, machine readable, non-contact type. The primary identifier is read using a machine to provide primary identification information. The secondary identifier is also read using a machine to provide secondary identification information. The primary identification information and the secondary identification information are compared and the identity of the item is confirmed only if the comparison results in a match.
