Abstract
A secured document, in the form of a booklet made up of at least one page that can be folded about a folding axis, includes a transponder provided with an electronic chip including memory for data storage and a transponder antenna. The secured document further includes two amplifier antennas, separate from the antenna of the transponder, arranged on pages of the booklet so that, in the open document position, one of the amplifier antennas amplifies the electromagnetic flux picked up by the antenna of the transponder to allow the document to communicate with a remote reader, and, in the closed document position, the amplifier antennas are configured so that the electromagnetic flux picked up by the antenna of the transponder is below a minimal threshold that allows the electronic chip to communicate with a remote reader.
