Abstract

Le problème décrit par la présente invention est d'éviter qu'un code à barres affiché sur un terminal portatif puisse être facilement copié, par exemple par photographie de l'écran dudit terminal, puis utilisé de manière détournée ou abusive par une tierce personne. La solution selon l'invention porte notamment sur un dispositif d'affichage de code à barres qui est doté : d'une unité d'acquisition d'informations de code à barres conçue pour acquérir des informations de code à barres servant à l'affichage d'un code à barres; d'une unité d'acquisition d'informations de changement d'affichage de sortie destinée à acquérir des informations de changement d'affichage servant à émettre un affichage de changement prévu pour changer une couleur, une forme et un motif, ou une combinaison de ces trois caractéristiques, au fil du temps; et d'une unité de sortie d'affichage permettant d'émettre, vers le même écran, un code à barres basé sur les informations de code à barres acquises, et un affichage de changement basé sur les informations de changement d'affichage acquises.
