OVD Role

The main role of the OVD is to provide a visual authentication function.
The OVD must provide a unique, hard to imitate  visual effect. It must be easy to explain and to memorize.

Our OVD’s  are revealed by 3 quick and easy natural tilting movements during the its observation :
– Top / Bottom
– Left / Right
– 90° Rotation

 To facilitate the memorization and thus improve the control’s efficiency, one movement shall induce one visual effect only.
