Abstract
A method for creating an identification document that includes: defining a debossed region on a surface of a card blank, the debossed region having a pre-determined pattern being indented into the card blank; and applying, as part of a lamination process, an overlay on the surface of the card blank to cover the defined debossed region such that an air gap is formed on the card blank's surface during the lamination process and is sealed and removed after the lamination process, and that a tactile pattern thus created on the surface of the overlay substantially duplicates the pre-determined pattern of the defined debossed region.
