Abstract

L'invention concerne un procédé d'achat d'articles qui utilise le clavier doté de capacité de reconnaissance de cartes, ainsi qu'un système de sécurité de transactions électroniques. Ledit procédé comprend notamment le serveur prestataire d'informations qui informe sur l'achat d'articles ainsi que le serveur de mécanismes conçus pour réaliser des règlements monétaires, les deux serveurs étant connectés au réseau de communications. Concernant sa connexion à ce réseau pour réaliser la transaction électronique, l'utilisateur devrait se connecter au site commercial sur Internet du serveur prestataire d'informations précité pour choisir les articles voulus. Dans le cas où il a recours au coffret de sûreté ou au numériseur de cartes pour ce qui concerne le coût de l'article, il sera relié à la ligne distincte du serveur de mécanismes de règlements monétaires précité. Le reliquat ou le montant consommé concernant le procédé de règlement sera alors indiqué. Le règlement s'effectuera avec la fourniture des informations monétaires sauvegardées confirmant la réorganisation. En matière de transactions électroniques, l'utilisateur peut procéder à des règlements de manière pratique grâce à une carte ou un compte sans sortie d'informations concernant son crédit personnel. Il peut utiliser ce règlement monétaire sans crainte, ce qui entraînera l'expansion des transactions électroniques et renforcera les ventes.
