Abstract

L'invention porte sur un système de communication sécurisant et simplifiant le commerce électronique comportant un centre de gestion des ventes (300) fournissant des informations sur l'introduction de produits à un terminal relais (400) qui les retransmet à un terminal utilisateur (500) qui à son tour crée un message électronique de commande sur la base des informations produits et l'envoie à un centre de gestion (100). Ce dernier (100) conclue une transaction électronique avec un centre de transactions (200) en fonction du message de commande électronique, puis envoie au terminal utilisateur (500) et au centre de gestion des ventes (300) un message décrivant le résultat de la transaction. Comme le système de communication est en circuit fermé, on évite la fuite d'informations privées vers des tiers.
