Abstract

Un lecteur RFID (44) présentant une antenne planaire (45) est installé sous la surface de transport d'une table de travail (20) pour préparer la liste d'identification des articles dans une benne (50). La modification des listes d'identification après l'arrivée de la benne (50) au niveau de la table de travail (20) est générée sous la forme de la liste des articles à prélever. Puisque l'antenne n'est pas installée sur la partie supérieure de la benne, l'identification de l'article peut être lue sans gêner le prélèvement.
