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.

Shielded contactless electronic document

A document which includes a cover, one or more internal pages, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, an electromagnetic shield capable of partially disrupting wireless communication with the radiofrequency microcontroller when the document is closed, and not disrupting the wireless communication when the document is opened is described. The electromagnetic shield included in the document is implemented using metal, conductive plastic, conductive ink or magnetic ink.

A device for communicating with a portable data medium using at least a power signal (AL) supplied by an electric energy source (,), a control signal (SC,) and a data transmission signal (I/O), comprises an interrupter (,) for interrupting the power signal (AL) to the medium from the source if the portable data medium does not cooperate with the device (,), means (,) for storing electric energy received from the source and for supplying the power signal to the medium when the source does not supply power and a data processor (,) arranged to ensure transmission of the power, control and data transmission signals (AL, SC,, I/O) to the medium according to a predetermined sequencing, as well as for detecting the interruption of the power signal (AL) from the source, then for triggering the interruption of the control and data transmission signals (SC,, I/O) according to the predetermined sequencing during the supply of the power signal from the energy storage mean.
