The aim of the invention is to provided a portable information carrier equipped with a transponder that can be activated and deactivated during the use of said carrier without requiring the actuation of a specific device. To this end, a portable information carrier is provided that has at least two essentially planar parts (A, B) that are joined to one another in an articulated manner while forming an assembly of which one part can be placed over the other. The first part (A) comprises a transponder (TA) situated in the plane of said part (A). The second part (B) comprises a shielding element (SB) extending over all or a portion of said part (B). The transponder (TA) is designed for being read by means of an appropriate reader while transmitting an electromagnetic signal that activates the emission of a response by the transponder (TA). The invention is characterized in that the transponder (TA) of the first part (A) is positioned opposite the shielding element (SB) of the second part (B) when the two parts are placed one above the other while preventing the activation of the transponder (TA) by absorbing the signal transmitted by the reader. This activation is effected only when the parts are located at a distance from one another whereby permitting the transponder (TA) located at a distance from the shielding (SB) to appear.
Le but de la présente invention est de proposer un support d'information portable équipé d'un transpondeur pouvant être activé et désactivé lors de l'utilisation dudit support sans recourir à un dispositif spécifique à actionner. Ce but est atteint par un support d'information portable comprenant au moins deux parties (A, B) sensiblement planes articulées l'une à l'autre formant un ensemble dont une partie est superposable sur l'autre, la première partie (A) comporte un transpondeur (TA) disposé dans le plan de ladite partie (A), le seconde partie (B) comporte un élément de blindage (SB) s'étendant sur tout ou partie de ladite partie (B), ledit transpondeur (TA) étant destiné à être lu au moyen d'un lecteur approprié transmettant un signal électromagnétique activant l'émission d'une réponse par ledit transpondeur (TA), caractérisé en ce que ledit transpondeur (TA) de la première partie (A) est positionné en regard de l'élément de' blindage (SB) de la seconde partie (B) lorsque les deux parties sont superposées empêchant l'activation du transpondeur (TA) par absorption du signal transmis' par le lecteur, ladite activation ne s'effectuant que lorsque lesdites parties sont écartées l'une de l'autre et laissant apparaître le transpondeur (TA) éloigné de l'élément de blindage (SB).
