A Quick Response code is simply a barcode, much like the black and white vertical stripes you see on items in a supermarket. Whereas supermarket barcodes only store a small amount of information (typically, the 13 numbers which identify the product), QR codes can store a lot more information in a smaller space.
This is because they use a grid of dots, rather than simple vertical black and white bars, which is why they are described as 2D (two dimensional) barcodes.
They also use a sophisticated mathematical formula, or algorithm, which compresses the number of dots needed to store the data. In this way, a relatively small QR code can store quite detailed information, such as a web address, a person's name, or even that person's entire contact details.
Most modern smartphones will automatically recognise a QR code when the camera app is opened and the device pointed at it. Some older devices will need to have an app installed on their phone, called a QR Reader, which are mostly free of charge and available from all of the app marketplaces.
This short (1 minute) video shows a Japanese customer using a smartphone to read a Quick Response code from the front page of a magazine, which takes the customer to the publication's website.
QR codes can also do other things when read by a smartphone, such as compose a text message which the customer can send instantly (useful for opting in to text-marketing campaigns) or simply to display a few words on the customer's screen.
The short answer is: you probably don't. Although QR codes have been around since 1994, they have only recently found their way into the marketer's toolbox, and while QR gurus will declare that they are the most important thing in marketing today, the reality is they have been slow to catch on.
Part of the reason for their sluggish uptake is the general lack of awareness amongst consumers of what they actually are.
Some marketers point to this fact as a benefit though – the curiosity factor, whereby consumers look at a QR code and are motivated to find out what it is. However, few people have QR readers installed on their phones, and so would be unable to find out what a QR code did even if they wanted to.
New smartphones tend to have QR readers built in though, and the codes have been widely embraced in Japan, the home of emerging technologies. So if you are interested in being at the front of the tech-pack (or even if you just want to seem like you are) then adding QR codes to your business cards, advertising posters, point of sale displays, beer mats and presentation folders is probably no bad thing.
There are firms which will charge you handsomely to provide print-ready QR codes, but the reality is there are dozens of websites which offer them completely free of charge.
Our recommendation if you want a Quick Response code to direct customers to your website is Bitly (the site which shortens long web addresses) because it gives you statistics on how often your code has been scanned by customers, which can be a useful measure of whether it is worth continuing to incorporate QR codes into your printed materials in the long term.
If you want a QR code to do something else, or you don't need statistical tracking provided by sites like Bitly, we recommend QRExplore which allows you to create codes containing text, a phone number or a text message, as well as a website address.
The single most important factor is the size of the code. The smaller the printed size of the code, the longer it can potentially take a QR reader to focus on and interpret it, although as smartphone cameras increase ever further in resolution, this potential delay diminishes.
Our advice is that a QR code from bit.ly should not be printed at a size smaller than 15mm square. QR codes which include more data, and therefore have more densely-packed dots, should be reproduced at a larger size.
We would always recommend you check the QR code on our proofs using a QR reader, to make absolutely certain it scans accurately, and performs the correct action (ie. taking you to the right website or displaying the correct contact data).
It all depends on the importance you place on being seen to be at the forefront of new developments, and of course, on your target market. Younger consumers are most likely to have a QR-enabled smartphone, and will also embrace the curiosity factor of QR codes much more readily as they become more widespread. If the 16-30 age range constitutes the majority of your audience, you should certainly be considering how you can use Quick Response codes.
If your product or service is less technology-oriented, or your customers are unlikely to use smartphones, then a QR code at best simply wastes space, and at worst, can alienate consumers who appreciate more traditional or conventional marketing messages.
We are more than happy to help you create QR codes, and naturally we can offer advice in incorporating them into designs intended for print. Please contact us on 01492 818515 or see our other ways of getting in touch.
