Abstract: An electronic card includes an element for transmitting a signal to a user of the electronic card, an electronic unit, an electric energy source, a switch actuatable by a user of the electronic card and an application introduced into the electronic unit. The electronic unit includes an element for detecting actuation of the switch, arranged for determining whether the actuation ends within a first time interval from the start of actuation (t0), the end of the first time interval occurring after transmission (t1) of a signal perceptible to the card user, or for determining whether the switch actuation ends within a second time interval (T2max) from the start of transmission (t1) of the user perceptible signal, the application being actuated or the actuation thereof being validated when the detection element has detected the end (t2) of the switch actuation within the first time interval or the second time interval.

Abstract: The invention relates to a method for fabricating electronic cards, that comprises the following steps: A) forming a plurality of card bodies in the form of a thick sheet (36) in which is respectively imbedded a plurality of electronic units or modules (28); B) printing a plurality of first patterns (14) on a first face (21) of said thick sheet in a printing station in which ink is applied on the first face for making said first patterns; C) applying a first at least partially transparent coating (38) on each printed first pattern, that adheres to said card body. In an advanced embodiment, the method also comprises printing a plurality of second patterns (40) on the inner surface of a film (38) forming said first coating. Preferably, the printing of the first patterns is carried out in an offset type station for printing high definition patterns, essentially of the security type. The second patterns define personal data.
