A security device (10) having: a base (12) having a pattern (14) thereon; a mobile component (16) disposed in contact with the base (12), the mobile component (16) containing a plurality of reversibly adsorbable particles; and a cover (20) attached to the base (12) around the mobile component (16) to maintain the mobile component (16) in contact with the base; wherein the adsorbable particles are mobile and reversibly changeable between a first state where the adsorbable particles are adsorbed to at least a predetermined percentage of the pattern and a second state where the adsorbable particles are adsorbed to less than the predetermined percentage of the pattern.
L'invention concerne un dispositif de sécurité (10) présentant une base (12) sur laquelle se trouve un motif (14) ; un composant mobile (16) disposé en contact avec la base (12), le composant mobile (16) contenant une pluralité de particules adsorbables de manière réversible ; et un couvercle (20) fixé sur la base (12) autour du composant mobile (16) pour maintenir le composant mobile (16) en contact avec la base. Les particules adsorbables sont mobiles et peuvent passer de manière réversible d'un premier état où les particules adsorbables sont adsorbées à au moins un pourcentage prédéterminé du motif, à un second état où les particules adsorbables sont adsorbées à un pourcentage inférieur au pourcentage prédéterminé du motif.
