description The invention relates to a secured document in the form of a booklet of at least one sheet which may be folded about a folding axis, the document having a transponder with an electronic chip provided with a memory for storing data and a transponder antenna. The document also includes a foldable amplifier antenna, distinct from the transponder antenna and arranged on the document such that, when the same is open, the amplifier antenna amplifies the electromagnetic flux received by the transponder antenna to permit communication of the document with a remote reader and, in the closed position of the document, the amplifier antenna reduces the electromagnetic flux received by the transponder antenna beneath a minimum threshold permitting communication of the electronic chip with a remote reader.
