Abstract
A document with a cover having a first cover part, a second cover part, at least one internal page located between the two cover parts when the document is closed, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, and an electromagnetic shield capable of disrupting, at least partially, the wireless communication with the radiofrequency microcontroller when the document is closed and not disrupting the wireless communication when the document is opened. The electromagnetic shield is a wire grid. The wire mesh distance between each two adjacent wires of the wire grid is smaller than a radio-frequency wavelength used for communicating with the radiofrequency microcontroller, and is at least 0.1 millimeters and at most 40 millimeters.
