Abstract
On juge correctement si une étiquette qui est fixée à un emballage et qui circule peut être utilisée ou non. Un dispositif d'inspection acquiert la valeur de la mesure en mesurant actuellement la qualité de lecture des données d'une étiquette et acquiert des informations d'identification pour identifier la destination de l'étiquette. Le dispositif d'inspection lit la valeur de référence de la qualité correspondant à la destination de l'étiquette dont la qualité de lecture de données a été mesurée à partir d'une section de stockage servant à stocker une valeur de référence de la qualité afin de déterminer les durées d'utilisation des étiquettes dans une pluralité d'environnements où les étiquettes peuvent être mises en circulation. Si la valeur de la mesure acquise satisfait la valeur de référence de la qualité, le dispositif d'inspection détermine que l'étiquette, dont la qualité de lecture de données a été mesurée, peut être utilisée.
