The invention concerns an electronic card including means for transmitting a signal to a user of said electronic card, an electronic unit, an electric energy source, a switch that can be actuated by a user of the electronic card and an application introduced into said electronic unit. The card further includes means for detecting actuation of said switch, arranged so as to determine whether said actuation ends within a first time interval from the start of actuation (t0), the end of said first time interval occurring after transmission (t1) of a signal perceptible to the card user, or for determining whether said switch actuation ends within a second time interval (T2max) from the start of transmission (t1) of said user perceptible signal, said application being actuated or the actuation thereof validated when said detection means have detected the end (t2) of said switch actuation within said first interval or said second time interval.
