The card (2) has a switch (12) that is actuated by a user of the card, and an application introduced into an electronic unit (6). A detection unit detects actuation of the switch, and determines whether the switch actuation corresponds to a pulse whose length is comprised within a certain predetermined time range or to a series of pulses defining a digital signal with a time profile. The application is actuated or the actuation is validated when the detection unit detects the pulse or series of pulses, where the application is a personal identification program. |
