The card has a detection unit for detecting actuation of a switch. The detection unit determines whether actuation is terminated within a time interval, where the actuation is terminated after transmission of a signal perceptible to a card user. The detection unit determines whether the switch actuation is terminated within another time interval (T2max) during transmission of the signal, where the actuation is validated when the detection unit detects termination of the switch actuation within the intervals. |
