Posted: September 9th, 2015 | Author:admin | Filed under:General | Comments Off on Colour QR Codes
One of the more common reasons why a QR code won’t scan is because there isn’t enough contrast between the foreground and background colour used.
For a QR code to be scanned reliably the contrast difference between the foreground colour and the background colour used in the QR code image must be large enough for the camera in the scanning device to be able to identify the QR code pattern against its background.
If the contrast between the foreground and background colours isn’t large enough then the scanning device won’t able to “see” the QR code image against the background and hence won’t be able to scan it and decode it.
So, how much contrast is required? The answer is in two parts.
1. Tonal Contrast vs Hue Contrast
Many QR code scanning apps scan in black and white (grey-scale) and not in colour so the “contrast” value actually relates to the difference in the grey-scale tone (or brightness) of the two colours used and not the differences in their hues (colour).
To show the difference between Hue Contrast and Tonal Contrast here’s two QR code shown in colour and as their grey-scale equivalent – basically what we see versus what the scanning app “sees”.
While there’s an obvious difference in foreground and background colour used in each QR code, the grey-scale tonal contrast in both cases is pretty much zero. Because it scans in black and white the scanning app won’t “see” the colours, just the greys, and hence not being able to discern the QR code image, the scan attempt will fail.
2. How Much Tonal Contrast Is Enough?
The amount of tonal contrast to ensure a reliable scan is going to depend on several factors:
Ambient light – not even a black and white QR code will scan in the dark.
Surface reflection – a shiny QR code image will reflect white. Not good if it’s on a white background.
Scan distance – the further away the QR code is, the smaller it looks to the camera and hence the more pronounced the distinction between foreground and background areas needs to be. This distinction is enhanced by a higher foreground to background colour contrast.
Camera quality – some cameras have a better tonal range response than others.
With a few variables at play it’s probably best to set a conservative tonal contrast level that’s going to work in the majority of situations and we reckon that safe contrast level is 40% or greater – ie; in terms of their relative brightness one of the colours should be at least 40% darker than the other one.
So, if your background colour has a grey-scale equivalent of 20% grey and your foreground colour has a grey-scale equivalent of 75% grey, then the tonal contrast is 70% – 20% = 50% tonal contrast. As this tonal contrast is greater than our recommended minimum of 40%, there’ll be no contrast-related scanning issues with this QR code.
Obviously a traditional black and white QR code will have the maximum possible scan reliability since its tonal contrast is 100% (white is 0% grey and black is 100% grey). As tonal contrast decreases from this 100% maximum so will the QR code’s theoretical scan reliability, but selecting a foreground/background colour pair with a tonal contrast of greater than 40% (and ideally greater than 60%) will ensure that your QR code functions as expected under most conditions.
The image below shows the approximate grey-scale equivalent of various shades and hues across the colour spectrum. ie; the black-and-white version of every colour in a particular row is represented by the same shade of grey.
Tonal Contrast Calculator
Here’s a handy tool that will help you determine the tonal contrast between two colours so that you can choose a QR code foreground/background colour combination that can be used with confidence.
Reverse Image QR codes
While we’re talking about QR code foreground and background colours and scan reliability I thought I’d briefly touch on another issue – reverse image QR codes, where the foreground is a lighter colour than the background.
While a reverse image QR code is supported under the ISO standard, it’s quite surprising how many scanning apps can’t read a reverse image QR code. Unfortunately this a scanning app thing and not a QR code thing so if you are intending to publish a reverse image QR code it might be a good idea to do a test scan on it first.
Here’s the same QR code in normal and reverse image versions – see how your scanning app works with them.
There’s always things going on at QRStuff.com and here’s some of the enhancements and features that we’ve added in the past few months, and a few things that we rolled out during 2014 but we may have forgotten to tell you about (sorry, our bad).
We’ve been doing QR codes globally since 2008 (we had our 7th birthday in January!), and as 2015 rolls on we’ll be releasing more new features, refreshing some of the older stuff, and just generally making sure that QRStuff.com continues be one of the world’s most popular (and longest-running) QR code creation websites.
Bitcoin QR Codes
Using our Bitcoin QR code data type you can now create a QR code to pass your Bitcoin address to another user or, if you specify an amount, to request the payment of a particualr amount into your Bitcoin wallet.
Just enter your Bitcoin address, and optionally the amount, label (usually name of receiver) and message (usually transaction description), click on “Download QR Code” and you’re good to go.
For stability and cross-platform compatibility across all major wallets, particularly in the mobile space, we’ve chosen to use the bitcoin: custom URI scheme (BIP-0021) for encoding, rather than raw URL’s.
DXF File Output – Paid Feature
A common request from users was to have a file format more suitable for use with 2D and 3D CAD work in cases where a QR code needed to be added to a plan, a schematic or a design file as an embedded link to an external data source or reference document. DXF (Drawing Exchange Format) is an ASCII CAD data file format that allows data interoperability between CAD programs and essentially turns the QR code into a discrete native CAD drawing object, so it made obvious sense to go with that one.
A standard part of the paid subscriber feature set is the ability to create QR code images in high resolution raster formats (PNG, JPG, TIF up to 600dpi) or vector formats (EPS, SVG, PDF), and adding DXF files to the list makes an already comprehensive range of output file types options just that much better.
Google Campaign Management – Paid Feature
Another addition to the paid subscriber feature set is the ability to integrate Google Campaign Management parameters directly into the QR code at the time of its creation. When you are logged into your subscriber account an additional input panel appears immediately below the data entry area where you can enter the standard source, medium and content parameters.
In addition to being able to add Google Campaign Management parameters to a QR code when its first created, for dynamic QR codes the parameters can be updated, or removed completely, through the subscriber account dashboard. They can even be added “after the fact” to an existing QR code that didn’t have them applied initially, and this includes dynamic QR codes created before the release of this feature. Static QR codes can only have Google Campaign Management parameters added at the time of their creation.
In the past our Email Message, Email Address and Phone Number QR code data types were only offered as static QR codes due to a few technical challenges at the phone end of things that we hadn’t really found answers to. As a result they were un-editable and didn’t have analytics reporting. Thanks to some recent advances in the way Android and iOS devices do things, those technical issues have resolved themselves to the point where can now confidently offer these data types with a dynamic creation option.
Short Version – If you’re a paid subscriber you can now edit and track dynamic Email Message, Email Address and Phone Number QR codes. Yay!
Instagram Data Type
A new Instagram QR code data type for linking to an Instagram profile using the instagram:// custom URI so that the Instagram app can be used to open the profile if the app is installed on the phone scanning the QR code.
vCard Notes Field
After quite a few user requests we’ve now introduced a Notes field to the data elements that can be include in our “Contact Details” (vCard) data type. Not a biggie, but still worth mentioning anyway.
QR Code Pausing – Paid Feature
We’ve provided paid subscribers with several customisable access control options for dynamic QR codes for several years now, including password protection, however those options have only dealt with access management for “live” active QR codes.
Pausing is a different approach and involves essentially de-activating an existing QR code for a period of time.
The pausing options we’ve made available to subscribers are “Manual” (pause it until you manually un-pause it) or “Scheduled” (pause it from now until a pre-specified time and date), and both of these pause methods have the choice of two pause actions to be carried out while the QR code is paused – specify your own custom “Message” to be displayed on-screen when the QR code is scanned, or a “Redirection” URL to take users to an alternative/temporary URL of your choice while the QR code is paused.
Pausing is only available with dynamic QR codes.
iOS 7 vCard Import
With the release of iOS 7 Apple finally allowed for the direct import of a vCard VCF file from an external source (like a QR code or web page) into the Contacts on an iPhone. Prior to that the only way to get the data from the QR code into the Contacts was to email a vCard VCF file back to the phone that was being used to scan the QR code as an attachment, and then adding the contents of the attachment to the Contacts. Very messy but it was the way it had to be done on an iPhone.
This restriction was lifted in iOS 7 so that vCard data could now be imported directly from a QR code into the Contacts on an iPhone – which is, by the way, how Android devices have always done things.
Our Contact Details (vCard) dynamic QR codes now actively detect the iOS version of the iPhone scanning the QR code and if it’s iOS 7 or better the vCard data is automatically offered to the user for direct import into the Contacts on the phone. Scanning a vCard QR code and importing the contact details it contains is now a simple and seamless process for all devices, unless of course you’re one of those people still using iOS 5 or iOS 6 😉
Android Tablet Support For App Store Download QR Codes
With our App Store Download data type QR codes you enter the store page URL’s for your app in the various app stores and when the QR code is scanned it will determine the device being used and re-direct the user’s device to the app store page that relates to that device. Scan it with an iPhone – get redirected to the page on the iTunes app store for the iPhone version of the app. Scan it with an Android device – automatically get redirected to the page for the app on Google Play. Simple!
Since we introduced App Store Download QR codes in late 2011 it has become one of the most popular data types and we have continued to enhance its functionality ever since.
As new app-enabled devices have been brought to market we have expanded the number of app store page link choices for App Store Download QR codes, starting with allowing separate links for iPhone and iPad app versions in late 2012, and then separate links for Blackberry BB10 vs legacy apps in 2013.
In 2014 the segmentation of the Google Play store into separate store pages for phone and tablet apps made it obvious that we should also offer the same segmentation at our end, so we introduced separate links for app store pages for Android phone vs tablet apps when setting up an App Store Download QR code.
Here’s what’s been going in our part of the QR code world over the past 3 months. The following data is based on the QR codes created by QRStuff.com users during January, February and March 2014.
Who Was Scanning QR Codes?
On a world-wide basis the location of QR code scan events hasn’t really changed all that much for us over the past 12 months. USA, UK, Australia and Canada are still in the top 5 however Malaysia has now moved up and pushed Germany down to #6.
We recorded scans from 216 countries during the quarter with Morocco, Kazakhstan, Ghana and Bolivia showing solid increases at the back of the field, and first-time scan events recorded from Equatorial Guinea and South Sudan.
For the USA the top 10 is still basically the same as last quarter however Virginia has continued its steady move up through the ranks over the past few quarters. Florida and Illinois are showing signs of softening but this hasn’t affected their rankings. Hawaii and Alaska aren’t shown on the map but came in at #40 (0.36%) and #44 (0.22%) respectively.
The top 10 for Europe remains essentially unchanged, and Europe continues to account for approximately 25% of the global scan events recorded.
What Were They Scanning Them With?
iPhones are still the most popular devices used for scanning QR codes. Over the past 12 months we’ve seen Windows devices move into double digits (they only accounted for 2-3% of scans in Q1 2012) with this growth principally at the expense of iOS devices and Blackberrys. Scans recorded from Android devices have increased globally over the past 2 years (up from 31% in Q1 2012) but have fallen away by 2% in the USA.
On a global basis the split for iOS devices was 39.4% iPhone and 10.1% iPad.
What QR Codes Were Being Scanned?
We keep an eye on two metrics – QR codes created and QR codes scanned – and it’s fairly safe to expect that the relative values for a given data type should be pretty much the same.
Following this logic through, if the relative number of scans recorded for a particular QR code data type is significantly greater than the relative number of those QR codes created, then it would indicate a greater number of scans per QR code, meaning that that particular data type is perhaps more effective in engaging than other data types. The reverse would also apply – if the relative scans are less than the relative rate of creation, then that data type could be considered to be less effective.
Obviously there’s a fairly significant flaw in that assumption – placement (contact details QR codes on business cards will get always get less scans than website URL QR codes in magazines) – however major disparities between the two relative figures that can’t be otherwise explained definitely give a strong hint as to which data types are more effective than others.
Our App Store Download data type is a case in point – while only representing 2.4% of the QR codes created by our users, they account for a whopping 20.9% of total scan events recorded. This data type is definitely punching above its weight in terms of its ability to engage with users and attract scans.
Posted: March 15th, 2014 | Author:admin | Filed under:General | Comments Off on How To Make QR Code Labels & Stickers
Here’s some step-by-step instructions on using a label template in MS Word 2010 to create QR code sticker labels from a pre-made set of QR codes using the mail-merge function. We’ve used the Avery 22805 label template (1.5″ x 1.5″ 24 per sheet) but you can use any digital label template you want.
These instructions assume you’ve already created your QR code images and have saved them locally on your computer. The end result will be a sheet of labels with each one containing a different QR code.
Create A Data Source
The mail-merge process intially requires a “data source” which should be prepared first. The data source contains the path location on your computer for each of the indivdual QR codes images that will be displayed in each of the labels (24 in our case since we are creating 24 different stickers on a single sheet of labels). The simplest way is to create an MS Excel spreadsheet contining the image file paths for each QR code in column 1. This column also needs to have a field label in row 1 which will be used as a reference in the mail-merge process later on. We used the label “qrcodes”.
Create and save this spreadsheet for later use.
TIP: MS Word can be a bit fussy about file paths so it’s best not to have any spaces in name of the folder your QR codes are saved in, or in the names of the QR code images themselves. Any weird characters in the folder name or image names should be avoided as well – just stick to a-z and 0-9
Open Your Label Template
Either open your digital template in MS Word (we downloaded our Avery 22805 label template from the Avery website) or use one of the templates pre-loaded into MS Word.
Select the “Mailings” command ribbon
Select “Start Mail Merge” and then “Labels”. Choose the template you require and press OK, or if you have already opened your own downloaded digital template just press Cancel (don’t know why this step has to be done when using your own template, but it won’t work if you don’t)
The Mail-Merge Process
Click on “Select Recipients” in the toolbar ribbon and then “Use Existing List” and navigate to the Excel data source file created above.
A dialog box will then appear – ensure that both “Sheet1″ and “First row of data contains column headers” are both selected and press OK.
Position the cursor in the first label cell:
Press CTRL + F9 to open the curly brackets, type INCLUDEPICTURE and then a space.
Press CTRL + F9 again, type IF TRUE and then a space.
Press CTRL + F9 again, type MERGEFIELD and then the name of the field identifier you used in your Excel spreadsheet created above. We used “qrcodes” so we type that.
Cursor across to the just before the last nested curly bracket and type \d.
After completing these steps you should have ended up with the following in the first cell:
TIP:The scripting shown above won’t work if you just copy and paste it in. You will need to do the whole CTRL + F9 thing as outlined in the steps shown above.
NOTE: You can also include other columns of information in your data source (such as a text label associated with each QR code), and the scripting could be extended at this stage of the process to include another MERGEFIELD parameter that pulls that data into the label as well.
Click on “Update Labels” which will populate all label cells with the mail-merge scripting. Each script is set up to pull consecutive images from your Excel data source file. eg; first listed QR code into the first cell, second QR code into second cell, third QR code into third cell, and so on.
Click on “Finish & Merge” and select “Edit Individual Documents”. Select Merge “All” Records and click OK. This will run the script in each label cell and replace the actual script with the QR code image referenced in it.
A new document will be opened showing each of the individual QR codes in their own label cell.
TIP:If you can still see the script text in each cell of the label template, rather than the actual QR code image, the press ALT+F9 to switch from Text View to Image View.
Save and print. Done!
Create QR Codes in Bulk Using Our Batch Processing Feature
A standard part of the QR Stuff paid subscriber feature set is the ability to automatically generate batches of up to 500 QR codes by simply uploading a spreadsheet file containing the details of up to 500 QR codes. The end result is a whole heap of individually and uniquely named QR codes that are ready to be imported into a label template using the process outlined above.
Visualead and QRStuff have joined forces to make QR codes more attractive for users and more valueable for businesses seeking to engage mobile users.
QR codes are all around us, and people are used to seeing and scanning them, yet they aren’t considered attractive. Visualead’s patent-pending technology changes how people engage with QR codes and enables users to easily embed them into any image or advertisement using a simple, user-friendly process that doesn’t require any graphic design skills.
Visual QR Codes are taking the humble QR code to the next level by keeping the tried-and-tested technology of the QR code and adding the elements of aesthetics and design to it. Visualead, the creators of the Visual QR Code, has teamed up with QRStuff, one of the the world’s most popular QR code generators, to allow the capabilities of a standard QR code to be added into any design or image.
Now anyone can integrate a QR code into any image, blending the familiar QR codes that people recognize with the visual design that people prefer, and in so doing creating a communicative, creative and effective visual call-to-action.
To get your Visual QR Code just vist www.qrstuff.com, create your QR code as usual, and then click on the Visualead banner in the bottom corner of the screen. The QRStuff and Visualead websites are directly integrated so you (and the actual QR code you just created) will be transferred seamlessly to the Visualead website where you can complete the process of making your QR code visual.
Who You Calling Ugly?
While there are other emerging technologies, QR codes are currently the most popular tool for businesses to connect their offline content to online interactive experiences, a bridge that instantly connects the physical world to the digital world.
Unfortunately the bland physical appearance of QR codes is often cited as one of its negatives. Customers are keen to engage and interact with companies and brands via their mobile devices but apparently they seem to find these blocky geometric computer-generated symbols a bit of turn-off.
Keep The Technology, Improve The Aesthetics
Incorporating a Visual QR Code into an ad layout or image combines the incentive to interact and engage with the technical means to do so, making Visual QR Codes more engaging, more communicative and significantly more effective with scans rates shown to be up to 25% higher when compared to a traditional QR code.
There’s also no more guessing where a QR code will lead to with a design-based approach making more opportunities available to communicate to users exactly what to expect when they scan the QR code.
Because of their look and feel, and also to save space in the layout, standard QR codes are usually reduced in size and tucked away in a lower corner of an ad. This reduces their impact and compromises their effectiveness – they can often go un-noticed or ignored, and scan rates suffer accordingly.
Visual QR Codes, on the other hand, allow the QR code to be placed front and center making it part of the ad rather than just a footnote to it. It ties in visually and aesthetically and becomes an integrated part of the message and an obvious extension of the principal call to action.

Any Image Can Become A Visual QR Code
Whether its your logo, your favorite social network icon or your app icon, you can now use any image to empower your brand awareness, be more attractive, be more intuitive, and get you more scans!
Founded in early 2012, Visualead’s mission is to make QR codes more appealing for customers and more valuable for brands by instantly and seamlessly blending them with any design, attracting users and increasing engagement.
The technology behind the Visualead’s Visual QR Codes is a unique, patent-pending image processing system developed by Visualead’s image processing and algorithms experts that enables users to merge a QR code with an image while preserving it as a fully operational QR code.

So, your’re a developer or publisher with an app in play across the various major phone platforms and think that a QR code would be a great way for your prospective users to download it? The only problem is that several platforms means several QR codes – one for the iTunes App Store, one for Google Play, etc – which makes things a bit messy. And what do you do about people that scan the QR code with a smartphone type that you don’t offer a version for?
With our “App Store Download” QR code data type we’ve solved this problem for you with one QR code that covers all smartphone types. At the heart of this QR code is an automatic device-type detection script at our end (that is completely transparent to the person scanning the QR code) that identifies what sort of phone they have and makes sure that the user is seamlessly sent to the app store that matches their smartphone type.
Simply enter URL’s of the pages on the various app stores that you do have versions for and this QR code looks after the rest.
For smartphone types that you don’t have an app version for (say, Blackberry) you can also specify a “Fallback URL” that the users of those non-supported devices will be automatically redirected to. This can be the website for the app itself, a greeting page for users of non-supported phones inviting expressions of interest for the release of that particular platform version, an announcement that that version will be available soon, or any other URL you think is appropriate.
Since we released it in May 2012, the “App Store Download” data type has been the single most commented-on data type by our users, with many taking the time to email us about how useful it is, particularly considering the cumbersome length and complexity of most app store URL’s.
Enter the link to the page for your app on the iTunes App Store.
If you have an Android version too then tick the box next to “Google Play App Link” and enter the link to the page for your app on the Google Play store. If you only have an Android version then untick the iTunes one and go straight to Step 5.
Repeat if you have a Windows and/or Blackberry version.
Enter your Fallback URL.
Download your finished QR code.
To maximise the flexibility of this type of QR code we’re also testing built-in implicit support for app store custom URI’s when used in place of standard http:// style page links. The custom URI’s currently supported are:
itms:// and itms-services:// for iTunes links
market:// for Google Play links
appworld:// for Blackberry App World
As an extra bonus this data type is fully dynamic so if you’re a paid subscriber you will be able to update the app store links whenever you need to.
Try It Out
Since our favourite QR code scanning app, Scan, is available on iPhone, Android and Windows Phone we’ve used that as our example above. We’ve added the links to the app store pages for their iPhone, Android and Windows Phone versions and made their own website the Fallback URL.
The finished QR code, and how it works, is shown below – try it out for yourself.
If you come across any smartphone types that don’t give the correct result just email us with the details – we’re constantly updating our device-detection database as new phone models are released.
We’ve just released a new data type that allows you to make a QR code that links to a Dropbox file or folder.
With the new “Share Link” feature on Dropbox you no longer need to create a Public Folder to share files. Just create the link, add it to a QR code, and you can instantly share Dropbox files with anyone, even non-Dropbox users, simply by them scanning the QR code.
Here’s how to use it.
Create A Dropbox Shared Link
Sign in to your Dropbox account.
Click on the file you want to share.
Select “Share Link” from the action bar across the top
A pop-up appears – click on “Get Link”
You will then be shown a preview of your file. Copy the link from your browser’s address bar to use when you create your QR code (below).
A basic fundamental of QR codes is that the pattern of modules in the QR code image is a direct graphical representation of the data it contains. That’s just the way QR codes work and is the essence of the algorithm that creates the QR code image.
This has one big downside – changing the data encoded into the QR code has the consequential result of also changing the QR code image which, at first glance, presents a significant problem if the website URL that the QR code links to needs to be changed. How to update the information in a QR code that’s already been published?
We grappled with this dilemma in mid-2008 and figured out that the simplest way to address this problem was to have a short URL actually in the QR code and then provide our users with the ability to change where the short URL then redirected to. In this way, the content of the QR code (and the QR code image itself) didn’t change (since it always contained that short URL), but where the user was sent to after the QR code was scanned could be changed at will behind-the-scenes.
This approach doesn’t actually make the QR code itself “dynamic” because its contents stays the same, but by putting a user-editable short URL into the QR code it gives the impression that the QR code can be changed and acheived the outcome we were after – this is still how all dynamic QR codes work to this day.
At the time we just thought this was a good way to pre-emptively make the creation of QR codes a bit more user-friendly, so we simply introduced it as a feature of the QRStuff.com website in October 2008 without any fuss or fanfare as a standard part of the way we did things.
Dynamic QR Codes
In the past 18 months or so the term “Dynamic QR Code” has been retrospectively applied to what we’ve been doing as a matter of course for nearly 4 years. Even though dynamic QR codes have been heralded of late as some new breakthrough in the underlying technology, they’re not. The only “new” thing about them is now they have a new name, which is probably a good thing because we originally called them “Re-Writeable QR Codes” which was pretty lame – we like the term “Dynamic QR Codes” much better.
So there you have it:
Static QR Code: The actual destination website URL is placed directly into the QR code and can’t be modified.
Dynamic QR Code: A short URL is placed into the QR code which then transparently re-directs the user to the intended destination website URL, with the short URL redirection destination URL able to be changed after the QR code has been created.
Dynamic QR codes greatly extend the useful life of a single QR code since, once published, where it sends the user to can be changed at will without it having to be replaced with a new QR code image every time the destination changes. A single QR code image can be deployed permanently in-the-wild and then simply re-tasked as and when required – link it to your own website this week, a YouTube video next week, your Facebook page the week after that, etc, etc. Or to different offer or coupon pages on your own website as each new promotional program is released over time.
They’re also handy when you have a temporary “placeholder” URL that will be changed once the final content or URL location is ready to go but the QR code needs to be created ahead of time, if the actual URL of your content changes unexpectedly (say, after a website rebuild), if you have a client who always changes their mind about what links where ( 😉 ), or simply to protect the on-going operation of the QR code from unexpected future circumstances.
QRStuff And Dynamic QR Codes
While many QR code generators make using their URL shortener mandatory, so every QR code is potentially dynamic by default, QRStuff.com users have the added flexibility of being able to choose whether they wish to make their QR code dynamic or static when they initially create their QR code.
Why, you ask, would anyone not want to create a dynamic QR code? Static QR codes have a few significant, but often overlooked, benefits that are outlined in an earlier blog post and regular user feedback over the years has confirmed that our original decision not to force everybody down the dynamic QR code path was an appropriate one to make, and has given us a strong point-of-difference in the broader market of QR code generation.
Anyway, the ability to edit the destination URL of a dynamic QR code is a standard part of our paid subscriber feature set.
When you log into your subscriber account history, any dynamic QR codes you’ve created will have an “Edit URL” option in the extended information about that QR code (click the “Manage” tab to the right of the history listing).
Using that subscriber feature, the destination URL that the short URL in the dynamic QR code redirects to can be modified at will without altering the QR code image. There are no limits on the number of times you can update the short URL destination.
About Our Short URL’s
As with all the mission-critical core service infrastructure of the QRStuff.com website, we have our own custom-built URL shortening service hosted on our own servers, and based on the qrs.ly domain that we own and host ourselves.
We don’t rely on any third-party services for the generation, management or security of the 2.5 million short URL’s that we’ve issued to date, ensuring that they work in a manner that is optimized for use with QR codes, fully protects the privacy of our users, and guarantees the confidentiality of the analytics data associated with the short URL’s themselves.
For added security, each short URL is generated randomly, rather than sequentially, so that consecutive short URL’s can’t be guessed or anticipated. We also don’t “recycle” short URL’s – every QR code created is given its own unique short URL regardless of whether other QR codes created by others users link to that same destination URL.
The following data is based on the QR codes created by our website users during January, February and March 2012.
Overall global QR Code activity is up 381% on Q1 2011 and up 16% on Q4 2011.
The Top 5 countries (Untied States, United Kingdom, Canada, Australia and Germany) have remained the same however their collective share of global QR code activitiy has decreased marginally since Q4 2011.
While the relative proportion of global QR code activitiy for the USA decreased from 49.0% in Q4 2011 to 48.1% in Q1 2012, QR code activity in absolute terms increased by 14% in the USA over the same period.
Email and SMS QR codes have increased in popularity at the expense of QR codes containing a website URL. Google Maps QR codes also showed a strong increase in popularity.
The disparity in device type used for scanning appears to have stabilised at approximately 60% iOS and approximately 30% Android.
QR Code Activity
While the stratospheric year-on-year growth rates seen through 2011 (albeit off a low 2010 base) have begun to tail off somewhat, significant increases between Q4 2011 and Q1 2012 were recorded for all countries in the top 20 with the exception of the Netherlands, that showed a reduction of 6%.
Overall the yearly growth rates reflect the adoption cycle of QR codes with earlier adopters like USA and Canada now stabilising in growth rates, while Europe exhibited in the last 2 quarters the sort of growth rates that North Amercia saw in Q3 and Q4 last year.
As the major markets that are using QR codes each move past the stage of over-heated and frenzied hype and opportunistic “snake oil” marketing, a much more solid and structured phase of adaption and deployment will follow characterised by marketers becoming more experienced and mature in their use, advertisers having a more realistic expectation of the role QR codes can play in their promotional mix, and the general consumer becoming more familiar with seeing them around.

“QR Code Activity” is a weighted index that we have created that seeks to quantify the relative changes in the overall number of people engaging with QR codes over time, as both QR code users and QR code publishers. The underlying data is taken from four sources – QR codes created on the QRStuff.com website, scan event data that we record on behalf of our users, our own website visitation analytics, and Google Insights For SearchTM data for key industry search terms. The latter data source is included to normalise any bias resulting from the growth in our user base having consistently out-stripped the growth in the market by 20% to 35% during any given quarter.
One interesting take-out when looking at the underlying data is that while the number of QR codes created at QRStuff.com increased by 16% between Q4 2011 and Q1 2012, the number of scan events recorded increased by 156% over the same period indicating a strong growth in the ongoing level of user engagement with those QR codes created and published in previous months.
QR Codes Created
Since 2011 QR codes containing email messages and SMS messages have increased significantly in popularity, as have QR codes containing Google Maps locations, with that increase being at the expense of QR codes containing a website URL.

Scanning Device Used
iPhones are still the most popular devices used for scanning QR codes. While Android devices showed some sign of narrowing the gap in Q3 and Q4 2011, the disparity is now pretty much 2:1. Blackberry’s continue to rapidly slide in popularity, however Windows Mobile devices have gained some of the ground they lost earlier in the year.
We still hold to the point of view that the scanning apps available for iPhone users are of a significantly higher quality and sophistication leading to higher useage rates, higher user satisfaction and higher user retention for iPhones compared to other devices.
The continuing publication of QR codes that are too dense to be read by a smartphone that doesn’t have a high resolution camera and/or optical image stabilisation will also continue to bias useage rates in favour of iPhones and away from older or less sophisticated devices on other platforms that give the user a less satisfactory scan result.
