<p>A secure document, in particular an electronic passport, includes a support equipped, on the one hand, with active security devices having a microcircuit connected to an antenna that can produce an electromagnetic response when it passes through the electromagnetic field of a contactless reader designed to query the identity document. The support is equipped, on the other hand, with passive security devices selected so as to have electrical characteristics, in particular inductive, capacitive and resistive, that are suitable for amplifying the electromagnetic response of the active security devices to make it go beyond a threshold that allows the secure document to be identified when it is placed in the electromagnetic field of a contactless reader. The invention has a useful application in national programs to issue passports with increased security.</p> |
