AUTHENTICATOR CF™ User Manual v2.1
A personalized page of a document covered with a protective laminate may show
certain retro reflective patterns when viewed with the coaxial illumination. When
viewed with one of the diffuse illuminations the same page will not show the retro
reflective pattern. Thereby the existence of such a laminate can be checked
visually.
The coaxial light product feature of the D SCAN AUTHENTICATOR CF does
not provide any kind of image processing or image analysis e.g. intended for the
automatic detection of tampering and alteration of documents having security
laminates such as the 3M™ Confirm™ Laminates.
Cross Match Technologies does not provide any product option or product
extension or separate product for performing such kind of automatic detections.

showing a document having a 3M™ Confirm™ Laminate on top of the
personalized page. The retro reflective marks are clearly visible while the
underlying text and pictures are almost invisible.
