Abstract

L'invention concerne un dispositif électrique pour l'authentification d'un objet physique en combinaison avec une première pièce électrique et un dispositif à capacité de communication en champ proche (CCP). Le dispositif électrique comprend une seconde pièce électrique. La première pièce électrique peut être couplée (peut être collée) à l'objet physique. La première pièce électrique et le dispositif électrique sont des éléments séparés conçus pour être disposés l'un par rapport à l'autre et par rapport au dispositif CCP de manière que, lors de l'utilisation, la première pièce électrique et la seconde pièce électrique sont couplées électriquement pour former un circuit résonnant qui comprend un élément électrique inductif et un élément électrique capacitif. Ce circuit résonnant est formé de manière qu'un couplage inductif entre le dispositif CCP et l'élément électrique inductif est engendré. Ce couplage inductif est engendré de manière à donner lieu à une communication CCP entre l'élément électrique inductif et le dispositif CCP.
