Seeing a QR code is all too familiar for Austrlians in this day and age – we can thank COVID for that.

However, there is a silver lining for businesses that are keen to leverage this new found technology in their marketing activities – spoiler alert, the technology is actually quite old…

Here’s how and why QR codes can work for your business (FYI, they cost nothing to generate).

Firstly, it’s not new technology

QR codes (QR meaning ‘quick response’) were first invented in, believe it or not, 1994.

That means those 2D barcodes of black and white squares that have become synonymous with checking into restaurants, cafes, petrol stations, pretty much everywhere in today’s COVID era are older than the Sony PlayStation 1.

Like the video game console, QR code origins come from Japan.

Japanese auto parts manufacturer, Denso, is responsible for introducing QR codes to the world.

The original purpose was to track auto parts and vehicles for high-speed scanning and tracking.

With the arrival of smartphones, QR codes have found many more uses than fan belts and fenders.

The list is huge, but here are a few things that QR codes can link a smartphone user to;

  • Email addresses / compose email
  • Email signups
  • Phone numbers
  • Digital business cards
  • Web pages
  • YouTube videos
  • App downloads
  • Timetables / schedules
  • Online purchases / payment methods
  • T&C’s

Basically, anything with a web link.

QR codes vs barcodes

The main difference between barcodes and QR codes is size. Barcodes are limited to what can be placed in one line of stripes. QR codes, on the other hand, add another dimension from which information can be written and scanned.

This is why you’ll often find checkout operators at supermarkets having to make sure barcodes are close to level when scanning but your phone will read a QR code from pretty much all angles. The three squares, usually in the top two and bottom left or right corners, are for determining the orientation of the code.

QR codes can also store far more information on them than traditional barcodes.

A standard barcode may be able to tell a product number and its expected location, but a QR code can provide the condition of the product, when it was made, any repairs done, among other things.

Businesses can share far more information when using QR codes.

Mass adoption

You’d think that if QR codes are so fantastic, they would have been mainstream back in the 1990s. Most people only became familiar with them a quarter of a century after their advent.

The problem was reading them. Until recently, QR code readers were expensive, cumbersome devices, handy in a factory but not something consumers could fit in their pockets.

Like many things in life, smartphones changed the game.

Fortunately, QR code developer, Denso, made the technology publicly available so that anyone could use it freely.

This allowed the codes to be used by people and businesses all over the world, massively boosting development.

As early as 2002, the general public, mainly in Japan, had access to mobile phones with QR code-reading features. Although primarily used for simple coupons, the early use proved popular with consumers curious about the strange patterns on advertising material.

By the mid 2010s, most people had access to QR codes, even if they didn’t know it. During these years, many apps such as chat apps Line and WeChat implemented the codes for users to connect with other users. Software developers incorporated QR readers into their apps with the use of phone cameras.

In 2017, Apple’s iOS 11 enabled its native camera app to scan QR codes.

Today, you won’t need to download an app to read a QR code, most phones have them standard so users simply open their cameras, point and read.

QR codes in marketing

There are two main reasons why QR codes can help a business.

  1. Directing people to a specific place online
  2. Tracking first-party data

The first reason covers the bulk of it. QR codes can direct users pretty much anywhere online.

For example, you might place a QR code that directs people to your asset finance quote tool on a printed brochure.

Codes can be ‘mini’ too, those tiny QR codes you may have seen, which allows for use on business cards and other small objects.

Typically, QR codes allow people to make the jump from printed material to digital material in one step.

Examples include:

  • Business cards directing to a LinkedIn page
  • Christmas cards to a promotion
  • Brochures to online quotes
  • Congratulations letter to a refer a friend page
  • Printed documents asking for reviews
  • Merchandise with codes linking to your homepage

QR codes make accessing a particular page a lot easier and faster than unlocking a phone, opening a new browser tab and entering an address.

Tracking data is also extremely useful for businesses.

This means logging the number of people who access your code, along with the time and date.

For example, if you set up a booth at a trade show, you’ll be able to see how many people accessed your codes during the event.

You can track scans in Google Analytics. Google Analytics also allows you to view demographics, locations and more.

Get started with your QR codes

Creating a QR is easy, especially with tools like the following;

They are free to use but some require signing up to access additional features such as custom colours and incorporating logos.

Programs like Adobe InDesign also give you the ability to create high-resolution QR codes.

You’ll be able to select whether you want the code to open a new email message meaning people are prompted to send you an email (therefore, capturing their address) – SMS and phone calls work the same way.

Alternatively, link scanners to a Google Map location, social media page or a website.

Make sure to

  • Test your QR code before distributing
  • Ensure you’re using the correct type of QR code for your aim (selectable on platform)
  • Ensure you’re able to track scans (available on platform)
  • Use on brand colours / logos within a code

Note that DYNAMIC QR codes can be updated (i.e., you can change the link source) and can track data. These are the best choice for most businesses and selectable via the platforms above.


The fun part for most people is the design process. QR codes can be more than a bunch of black and white squares these days.

When creating a QR code, you’ll be able to implement your brand’s colours so make sure to have the colour hex codes associated with your company handy.

You can incorporate more than one colour too.

You can also incorporate your logo with a QR code. To do so, you’ll need an image (jpeg or png) of your logo. 

Social media
Make sure to link the channels correctly, you don’t want Facebook linking to your business admin page or an Instagram button directing people to LinkedIn.

Other intricacies
You can also tweak the borders (style and colour), orientation squares (those 3 locator squares mentioned above), pattern design, loading screen logo and more.
