Le code barres 2D !!

-
Les codes barres en deux dimensions aussi appelés flashcodes ont été créés en 2002 et sont actuellement très utilisés en Asie, plus précisément au Japon qui les utilise couramment dans la vie quotidienne. Aujourd'hui, en France, aucun de ces codes barres n'est vraiment utilisé dans la vie de tous les jours et pourtant, les fonctionnalités sont multiples et méritent le détour !

Le principe des flashcodes


Des codes barres 2D vous en avez peut-être déjà vus, mais utilisés ce n'est pas sûr. En fait, ceux-ci contiennent beaucoup d'informations codées, jusqu'à 7 089 caractères, contrairement aux codes barres traditionnels qui ne peuvent en contenir que 10 ou 13.

Il est impossible de les lire à l'oeil nu : pour ce faire, il faudra se munir d'un lecteur spécial installé sur un téléphone portable. D'ailleurs, il se peut qu'un lecteur soit déjà installé sur votre téléphone. Le flash du code barres 2D peut déclencher toutes sortes d'évènements et d'actions, comme par exemple effectuer un appel téléphonique, écouter une musique ou encore envoyer des messages (SMS, Email).

Et pour déclencher ce type d'action rien de plus simple, il suffit de prendre une photo du code barres grâce au lecteur installé sur votre téléphone mobile et le tour est joué.

Voici un exemple en image, issu du site flashcode :
