Overt security features are those that can be seen. They are typically holograms that have either a distinctive visual effect or a technical feature that is difficult to replicate.

Today holography dominates the authentication market because no competing print technology works on so many levels of security (overt, covert and forensic), nor combines decorative, eye-catching appeal and kinetic effects. A key competitive advantage is the creation of increasingly impressive optical effects, such as parallax, which appear 3D and change form when viewed from different positions. Other value added features include the ability to record stereograms of photographic images or computer generated models.

The creative options are limitless and difficult to simulate, which is why demand for this dynamic technology is growing so rapidly.
