Abstract

Abstract Translated from French L'invention concerne un lecteur de cartes à mémoire électronique qui permet de marquer le corps de la carte afin d'indiquer le nombre d'unités de valeur déjà consommées. Le lecteur comporte une unité de traitement (44) qui permet notamment de connaître le nombre d'unités de valeur consommées dans la mémoire de la carte (10). Elle compare ce nombre à des seuils et commande l'activation du moyen de marquage (56) du corps (12) de la carte, par exemple une résistance chauffante, qui correspond au seuil franchi. The invention relates to an electronic memory card reader which makes it possible to mark the body of the card in order to indicate the number of value units already consumed. The reader includes a processing unit (44) which in particular makes it possible to know the number of value units consumed in the memory of the card (10). It compares this number with thresholds and controls the activation of the marking means (56) of the body (12) of the card, for example a heating resistor, which corresponds to the threshold crossed.
