LAMINATED IDENTIFICATION DOCUMENT AND METHOD FOR ITS' MANUFACTURE |
摘要 |
An over-the-counter type identification document is prepared by forming at least one first indicium (typically invariant data common to a large number of identification documents) on a core layer, sandwiching this core layer between a pair of substantially transparent polymer layers, providing an image-receiving layer on one or both outer surfaces of the resulting sandwich, forming a second indicium (typically variable data relating only to a single identification document) on the image-receiving layer(s) and laminating a protective layer or layers over the image-receiving layer(s). The identification document displays improved durability and security and can be rendered substantially identical in appearance to documents produced by known central issue production methods. |
