QR codes are now a common feature in marketing campaigns, though many people are often sceptical about their value.
This scepticism is often justified as, though we have seen some creative examples, QR codes are often used very badly.
Also, while it is easy to find creative examples, brands and marketers aren't always forthcoming about revealing the stats around campaigns.

He sold his first online advertising startup, ClickAgents, for $40m to ValueClick, followed by his second company, BlueLithium, for $300m to Yahoo.
His third venture, RadiumOne, has achieved huge success by using social data to target adverts across the web.

20th Century Fox tried to tap into the viral power of Twitter on Sunday night to promote the impending release of Ridley Scott’s sci-fi movie Prometheus.
In what was heralded as a world first, a new three-minute trailer for the film was screened simultaneously online, on Channel 4 and on social TV app Zeebox.

Google has announced that it is launching a price comparison service offering information on credit cards and bank accounts ahead of the natural search listings.
While Google’s price comparison service comes below the paid links, it includes images that make it more eye-catching than normal PPC ads.

Fewer than 10% of British adults have used a connected TV to go online, according to new data from Kantar Media.
The futurePROOF study found that just 17% of British adults own an internet ready TV set and more than a third (36%) of respondents said they did not see the point in going online through a TV set.
In fact the main motivations for buying a smart TV were traditional drivers, such as screen size and picture quality, rather than connectivity.
It has been a few months now since Twitter rolled out its mobile ads, offering companies the chance to target its 55m mobile users.
The social network says Promoted Tweets allow brands to target their followers as well as users “that share similar interests with their existing followers”.
This sounds like a good product for marketers: ads based on location and the user’s interests, and you only pay if the user engages with the ad by clicking or retweeting.
In the battle for fashion shoppers in natural search, research by I Spy Marketing shows that ASOS is trouncing the competition.
The e-tailer appeared in the top ten for 66 out of 72 generic fashion search terms in Google – Amazon was the second best performing retailer followed by Debenhams.
The Fashion Sector Report found that fashion brands and luxury clothes sites, with the exception of Net-a-Porter, were absent from the results.
Blackberry apps may not have the greatest reputation in the world, but recent updates suggest that social networks haven’t given up on the old boy just yet.
Foursquare announced on Friday that it had upgraded its Blackberry app to make it “speedier” and improved the GPS logic.
But that’s not all - notifications will now delivered into the Blackberry inbox and new NFC capabilities mean users can “share places and tips among other BlackBerry and Android devices… with a simple tap of your phone.”
The updates come shortly after Twitter rolled out Promoted Tweets to Blackberry devices following similar updates on Android and iOS.
