QR codes were first created by Toyota to track vehicles in manufacturing, offering a small barcode that can be quickly decoded. That was 1994, and now, almost 20 years later, QR code technology is experiencing a revival ...
Imagine walking down your city’s main thoroughfare one morning and you turn the corner to see a massive black and white sporadically-checkered pattern sprawled out on the side of a building in the shape of a square. Immediately you peg it as one of those QR codes you see printed in magazines and on the sides of shipping containers. You get out your nifty smartphone, access the bar code reader you downloaded last week (because it’s free) and hold your camera up to focus in on the huge QR code presented before you. Meanwhile, several other pedestrians are doing the same thing nearby. Who knows how many people can see such a massive display? At any rate, the scanned bar code takes you to a website notifying you of a new club opening in that building. Whether you’re a club hound or not, surely you’d admit that was a worthy marketing ploy.
Une des nouveautés du HTML5 est l’intégration dans les navigateurs de la géolocalisation. Dans ce rapide tutoriel, nous allons voir comment tirer parti de cette fonctionnalité pour créer des QR Codes qui contiendront non pas simplement les coordonnées GPS d’un lieu sur la carte mais l’itinéraire pour aller de l’emplacement actuel de l’utilisateur vers un lieu donné.
QR Codes are showing up on web pages, business cards, signage, store windows, coffee cups, and lots of other places but now, they can hang on your walls as art, proudly hanging right next to your prized Picasso.
