Is the humble QR code now an integral part of our day to day lives?

Nothing new

While we have seen a heightened use of QR codes recently, they are by no means new. They were born out of the barcode which was first developed by Denso Wave, a subsidiary of Toyota, back in the 1960’s. Japan had entered its highest economic growth period which meant cash registers were ringing. As cashiers entered prices manually the boom was starting to cause them injuries such as  numbness and carpal tunnel syndrome from the repetitive task.

The invention of barcodes provided a solution to this problem. Yet as the use of barcodes spread their limitations became clear. The biggest was that barcode can only hold 20 alphanumeric characters of information. The QR code could not only hold more information, but it could also be read more than 10 times faster. The QR code was first used in the auto industry and contributed to efficiencies across a wide range of tasks from product to shipping

Those who developed the QR code were unsure if it would gain market traction (little did they know). It is hard to find much information about the QR code until the early 2000s. At this time it became used in Japan for things like opening subway gates and banking

It’s everywhere

Since the early 2000’s the use of QR codes has grown. Not only amongst the Japanese public but globally. First taking off as a marketing tool now QR codes are now part of our daily lives, used for many things. Here’s a few examples:

  • electronic ticketing 
  • flight check-in 
  • food tracing 
  • joining a wifi network
  • loyalty programs
  • coupons

Keeping us safe in 2020

Many years have passed since the QR code was first invented. The COVID-19 pandemic has challenged us this year, with a greater focus on tracking our own movement. This extends to organizations and the need to be able to track who is entering their locations. QR codes are a simple and easy way to keep us safe.

Does this mean the humble QR code is now the sweetheart of this pandemic, tech, and our day-to-day lives?
