Estimating the term…
The electronic card comprises at least one integrated circuit disposed on a printed circuit board, connection means to an electrical supply source connected to the printed circuit board in order to supply said integrated circuit, and control means which can be actuated manually and are connected to the integrated circuit. The integrated circuit is provided for processing signals generated by the control means. Said integrated circuit, the control means at least a part of connection means to and the supply source are enclosed in at least one layer of insulating material forming said card. The control means are formed by an assembly of electrodes in order to define a touch screen with capacitive keys which can each be activated by means of a finger (D) of a user or a pen placed on one contact surface of the card opposite at least one touch key for introduction of data or a command. A conductive shielding screen is provided on one side of the electrodes of the capacitive keys which is opposite the contact surface.
