QR codes are generally total rubbish. This is not my opinion or thought on the matter but the complete and final fact. A quick Google helps to locate a whole bunch of awkward QR codes and even a Tumblr called “WTF QR Codes“. QR codes are a perfect example of a technology that marketers jumped onto without much thought of whether their customers would use this tech or even know what they were doing. My personal favourite was a newspaper that had street pole posters (about A3 size) with a QR code on them to download the iPad app. Assuming you actually stop your car are you really going to haul out your iPad and stand on the pavement taking a picture of a QR code to download an app? I thought not. This image is my personal favourite:
As travellers start to use Smartphones as a way to connect with their loved ones back home, navigate using the built in maps and GPS as well as replace their Lonely Planet guide book with Google and Wikipedia the streets of Rio De Janero have become a useful navigation tool thanks to QR codes.
The first two-dimensional bar codes, or QR codes, as they’re known, were installed at Arpoador, a massive boulder that rises at the end of Ipanema beach. The image was built into the sidewalk with the same black and white stones that decorate sidewalks around town with mosaics of waves, fish and abstract images. The code sent users to a web site that gave them information in Portuguese, Spanish or English, and a map of the area.
The city plans to install 30 of these QR codes at beaches, vistas, and historic sites, so Rio’s approximately 2 million foreign visitors can learn about the city as they walk around.
Not only is this an exceptionally cool service for tourists, I love the fact that they used similar construction styles to the area to create the QR code.
Finally proof that there is a use for a QR code!
