The A-Z of QR Codes
What is a QR Code?
The QR code is a two-dimensional barcode variety that can be scanned by smartphones. Unlike standard barcodes designed to store a maximum of 20 digits of data, a single QR code can hold more than 7,000 alphanumeric characters.
Hara Masahiro, QR Code inventor
It was invented by an engineer from Denso, an automotive components manufacturer headquartered in Aichi, Japan. Hara Masahiro said the idea came while playing a strategy game during his lunch break. Before QR codes, Hara and his team used standard barcodes to track their inventory. QR is short for “quick response”, which is an apt description since QR codes let users instantly access the information stored within them.
QR codes are either static or dynamic. A static QR code is fixed – once generated, you can no longer change the information stored in it. On the other hand, the contents of a dynamic QR code can be replaced or edited whenever necessary.
Parts of a QR Code
At first glance, a QR code may seem like a jumble of unique pixel-like patterns in a square grid, but it comprises different components.
Finder Pattern – These little squares on three of the four corners help the scanner identify the presence of a QR code and its corresponding orientation.
Alignment markers – If the QR code is blown up to fit a large area or is printed on a curved surface, this component helps the scanner identify the code’s correct alignment.
Timing pattern – These two perpendicular lines with alternating black and white dots indicate the size of the data matrix.
Format information – These patterns contain the QR code’s error tolerance levels in case it gets dirty or damaged.
Version information – These markers indicate the specific version of the QR code. Currently, there are 40 versions.
Data and error correction module – These patterns hold backup data. Compared to barcodes prone to tampering and smudging, QR codes are weather-resistant by design and remain readable even after sustaining 30% structural damage.
Quiet zone – This is what separates the QR code from its surroundings. Without this, the scanner won’t be able to read the code.
Advantages of Using a QR Code
Aside from its larger capacity and enhanced durability, the QR code is better than a standard barcode for three major reasons:
1. QR codes are instantly accessible
Any smartphone or tablet with a working camera can scan a QR code. Instead of manually typing a URL or reciting your contact information, you can simply store these details in a QR code and present them whenever needed. This makes QR codes a PWD-friendly solution as well.
You don’t have to print it out, either. As long as the QR code is not blurry nor pixelated, it can be easily read by a scanning app regardless of its size and surface. And like other barcode types, QR codes can also be read from any direction.
2. QR codes are trackable
Since information gets collected once the code is scanned, businesses that use QR codes can easily track who gains access to their data. This can include unique scans, location, timestamps, and even the device’s operating system. If you’re an entrepreneur or a marketer, you can use this information to understand your audience better, which can result in more effective marketing campaigns.
3. QR codes are not expensive
According to a 2021 study, 75.8 million smartphone users in the US alone scanned a QR code. A more recent survey revealed that 7 out of 10 restaurants in the country now prefer QR codes and mobile wallets as forms of payment.
It has come a long way; in 2012, 97% of consumers didn’t even know what a QR code was.
The resurgence isn’t just because QR codes are easy to use – they also cost nothing. There are many QR code generators online that you can use for free!

Successful QR Code Campaigns
With 59% of consumers believing that QR codes are here to stay, it comes as no surprise that businesses, marketers, and even the media have gone outside the box to maximize its convenience. Aside from making contact tracing more efficient during the COVID-19 pandemic, here are five more examples of noteworthy QR code applications all over the world:
In 2020, the French beauty and cosmetics group launched its virtual try-on tool in Ireland to promote the True Match Foundation. The QR codes were displayed in supermarkets and pharmacies nationwide. All customers need to scan the code and get redirected to the website where they can try on the foundation’s different shades.
Also launched in 2020, this initiative connects coffee drinkers to the farmers who grew and harvested their beans. Several brands and organizations in the coffee supply chain were involved in this project. QR codes about the origin and process were embedded in participating coffee products, which consumers can scan with the Thank My Farmer app.
