Abstract

L'invention concerne un procédé d'association d'une mémoire de données mobile à un appareil d'écriture/de lecture. Pendant une première liaison téléphonique entre l'appareil d'écriture/de lecture et la mémoire de données mobile, la mémoire de données mobile est ajustée par l'appareil d'écriture/de lecture de telle sorte qu'elle répond à un signal de recherche de l'appareil d'écriture/de lecture avec un second signal ayant des secondes pointes de corrélation et non comme lors de l'initialisation de la première liaison téléphonique avec un premier signal ayant des premières pointes de corrélation. Si un autre appareil d'écriture/de lecture reçoit le second signal lié aux secondes pointes de corrélation, alors l'autre appareil d'écriture/de lecture ignore la mémoire de données mobile. Ainsi, l'appareil d'écriture/de lecture peut mettre un terme à la première liaison téléphonique et par l'envoi d'un signal de recherche, auquel répond la mémoire de données mobile par le second signal, établir une seconde liaison téléphonique avec la mémoire de données mobile, sans que la mémoire de données mobile ne soit bloquée par un autre appareil d'écriture/de lecture.
