    • 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.
    • 通过在核心层上形成至少一个第一标记(通常是大量识别文档的常见数据),将该核心层夹在一对基本上透明的聚合物层之间来制备非处方型识别文件,提供 在所形成的三明治的一个或两个外表面上的图像接收层,在图像接收层上形成第二标记(通常是仅与单个识别文档相关的可变数据),并且层叠保护层 图像接收层。 识别文件显示出改善的耐久性和安全性,并且可以使外观与已知的中央问题制作方法生成的文件基本相同。
