Abstract

Le but de la présente invention est de fournir un support pour un présentoir de marchandises avec lequel il est possible de réaliser une gestion d'une pluralité d'articles de marchandises en temps réel et avec une plus grande fiabilité. Un support pour présentoir de marchandises selon la présente invention est destiné à afficher des articles de marchandise auxquels des étiquettes RFID sont fixées. Ledit support pour présentoir de marchandises comprend : une antenne de lecteur en forme de câble qui est disposée à l'intérieur d'un espace de présentation dans lequel une marchandise est affichée ou tournée vers ledit espace de présentation, et qui communique avec les étiquettes RFID ; et un élément de protection qui est disposé entre l'espace de présentation et un espace qui est extérieur à celui-ci, de manière à occlure au moins une partie d'ondes radio qui émanent de l'antenne de lecteur vers l'espace qui est extérieur au support pour présentoir de marchandises.
