SECURITY DOCUMENT HAVING A CONTACTLESS CHIP WITH DATA MASKING

摘要

The invention relates to a security document having a contactless chip with data masking. The security document (20) comprises a transponder (10) comprised of an electronic module (102) connected to an antenna (101) placed on a data surface of a first part (22) of the document, said transponder serving to remotely communicate with a reader via an electromagnetic coupling, and comprises a passive masking element (24) of said antenna, which is supported by a second part (21) of the document and can move relative to said first part, said masking element being capable of interfering with the coupling between the transponder and the reader for rendering the reading of the document impossible when the second part is in a predetermined position that corresponds to a closed position of the document.
