Abstract

Le problème à résoudre dans le cadre de la présente invention consiste à gérer en toute sécurité des articles associés à un opérateur sans qu’il doive réaliser diverses opérations, telles que la saisie et l’enregistrement. La solution proposée consiste en un dispositif de communication de données radio-émetteur (100) comprenant une antenne côté dispositif (130) qui effectue une émission/réception de données à destination/en provenance d’un élément de circuit radio-émetteur par radiocommunication. Une unité centrale (121) acquiert un identifiant dudit élément par radiocommunication via l’antenne côté dispositif (130). Chaque fois qu’une condition préétablie est satisfaite, l’unité centrale (121) met en corrélation l’identifiant avec un groupe d’identifiants et enregistre ce groupe ou un identifiant indiquant chaque groupe mis en corrélation par ce moyen dans un dispositif de stockage (121D) permettant l’écriture et la lecture de données.
