There are many that have written off quick response (QR) codes as having no real value going forward especially with the emergence of other technologies such as near field communication.
And, it's true that many QR codes applications to date have been impractical or don't seem to have had much thought behind them.
It might be too soon to consign them to the scrap heap however as a number of current initiatives demonstrate a bit more creativity and initiative.
First up, Compasscode in the US which is putting codes in hotels, restaurants and other businesses in an area to provide tourists, who scan the code via smartphone or tablet, with information about the area, maps and one-touch contact details for the businesses.
The service is free to hotels, airports and other venues which agree to have the QR codes on site while businesses, which want to appear within information about the local area, pay to advertise.
Compasscode boss Corey Bolton says about 200 hotels have signed up to the initiative with the codes already live within more than 75 properties.
The company also says it has patents pending on using QR codes for local search.
Back in mid-July, Gibraltar staked a claim to being the first Wikipedia city with QR codes on plaques around the city taking users to Wikipedia pages with information about the destination, attractions and famous people.
Geotags are also being incorporated into the pages so that tourists can view a virtual tour.
GibraltarpediA follows in the footsteps of MonmouthpediA, an initiative launched in May and devised by local resident John Cummins to link the town in South Wales to relevant Wikipedia articles via QR codes.
Both projects use QRpedia codes to serve up the Wikipedia pages.
