Underrated and often misused, QR codes are always seen as a bit of a joke by both our and industry digital experts.
Therefore I love it when someone uses them right. Well almost.
On 13 April 2012, the spanish rail service teamed up with book publisher Random House to place posters on the exterior of the central carriages of ten services traveling between Vallès Oriental and Baix Llobregat. Each poster encourages commuters to join the ‘reading train’ and once inside, interior posters provide riders with a selection of 40 book titles from which the first chapter can be downloaded via their respective QR codes.
As well as seeking to improve the literacy of residents using the train service, the scheme also serves to publicize works of literature, while readers are also entertained during their commute.
A good idea. However, just imagine that they linked this to iBooks or Amazon to allow passengers to download or order, and it would have been truly brilliant.
