Passport Sample Pages featuring 3dge
3dge is a unique new DOVID characterized by kinetic images that are visible only when tipped to an extreme (almost vertical angle) when lit from overhead.
This security device is 'semi'-covert because the image is not visible on casual inspection, yet verification is quick and straightforward requiring no proprietary tools. The differentiated image reconstruction angle makes it impossible to confuse with conventional holography plus it does not interfere with the legibility of printed documents at normal viewing angles.
To view 3dge, position the sample below eye level at a steep nearly vertical angle with incident light directly above.
