QR code, Smartphone, Application

Introduction

Crées en 1994, les QR codes sont des petits carrés de taches de couleurs blancs et noirs. Ces carrés contiennent un code qu'il est possible de lire à l'aide d'un lecteur depuis un smartphone, de téléphone portable ou d'une tablette numérique, qui permettent des actions variés en fonction du code qui a été intégré à l'intérieur.

...Certains QR codes redirigent vers une page internet précise, affichent des informations sur un produit, traduisent des pages, permettent de faire des achats en ligne, de lire des pages de vaccinations sur Anticovid, ...

...QR signifie "Quick response", soir réponse rapide en anglais, pour signifier la vitesse à laquelle on peut accéder à son contenu.

...Le fonctionnement des QR code est semblable à celui des codes barres.

Étape 1 - Installer une application de lecteur de QR Code

Pour pouvoir lire un QR Code, il faut déjà posséder un lecteur permettant de les scanner.

...Si vous en avez déjà un, vous pouvez sauter cette étape et aller à l'étape 6

Pour installer une application sur un téléphone portable, il faut aller aller sur l'application de votre smartphone permettant d'en télécharger.

Si vous ne savez pas de quelle application il s'agit, vous pouvez l'identifier en en cherchant une avec le mot "store" (boutique en anglais) dans son nom : Google store, App Store, ... (Image 1 : exemple de l'icône du store de Google, le "Play Store")

Étape 2 - Installer une application de lecteur de QR Code-1

Ouvrez l'application en appuyant dessus. Appuyez ensuite sur la barre de recherche pour taper le nom de l'application que vous souhaitez installer, à savoir "QR Code"

...Vous pouvez aussi appuyer sur le bouton en forme de micro à droite sur la recherche pour faire une recherche orale plutôt que de taper du texte.

Étape 3 - Installer une application de lecteur de QR Code-2

Les différents modèles de QR Code s'affichent à l'écran, choisissez un qui vous correspond et appuyez dessus.

Étape 4 - Installer une application de lecteur de QR Code-3

Appuyez sur le bouton "installer" pour télécharger l'application.

Patientez quelques secondes, votre lecteur de QR code est maintenant installé sur votre smartphone.

Vous pouvez appuyer sur "ouvrir" pour démarrer le lecteur.

Étape 5 - Installer une application de lecteur de QR Code-4

Étape 6 - Lire le QR Code

Ouvrez l'application du lecteur de QR Code.

...Si vous l'ouvrez pour la première fois, il va vous demander l’autorisation de connecter l’appareil photo de votre appareil, car il bascule dessus dés que vous l'ouvrez.

Vous devez maintenant faire correspondre le carré au milieu de l'écran sur le QR code, ce qui vous prendre quelques essais avant d'y arriver.

Vous savez maintenant lire des QR Code.
