<p>The aim of this invention is to propose a portable information carrier equipped with a transponder capable of being activated and deactivated during the use of said information carrier without having recourse to a specific device for actuation. This aim is reached by a portable information carrier comprising at least two substantially planar parts articulated to each other forming an assembly in which one part can be superimposed on the other, the first part includes a transponder arranged on the plane of said part, the second part includes a shielding element that extends over all or part of said part, said transponder intended to be read by means of a suitable reader that transmits an electromagnetic signal activating the transmission of a response from said transponder, wherein said transponder of the first part is positioned facing the shielding element of the second part when both parts are superimposed preventing the activation of the transponder by absorption of the signal transmitted by the reader, said activation being carried out when said parts are moved aside from each other, letting appear the transponder distant from the shielding element.</p> |
