    The Fascinating Story Behind the Invention of QR Codes

    The Origin of QR Codes

    QR code or quick response code is a 2D type of barcode that stands apart. Its invention is an intriguing story that began in the early 1990s in Japan. A subsidiary of the Toyota manufacturing company, Denso Wave, invented the QR code in 1994. Masahiro Hara, a Denso Wave researcher, is credited with inventing QR codes as a way to track car parts in the manufacturing process with much more significant amounts of data than the traditional barcodes.

    The initial design of the QR code allowed for differentiating a large amount of data from the traditional barcodes. The QR code could store up to 7,000 characters compared to the maximum storage capacity of 20 digits in the traditional barcodes. The objective was to improve the manufacturing process on the factory floor.

    The Need for QR Codes

    The idea was incorporated into the vehicle manufacturing process and provided greater efficiency in data management and production flow. Shortly after, QR codes gained widespread recognition outside the world of vehicle manufacturing. The codes were put to use to track inventories and to market products. Companies could provide detailed information about their products to customers through QR codes, and customers could access the information with much ease. This development laid the foundation for the use of QR codes in today’s fast-paced digital age.

    Japanese Connection

    Denso Wave’s creation of QR codes was a significant advancement in the evolution of barcode technology. In Japan, QR codes became instantly popular, and the Japanese embraced the technology with enthusiasm. Besides, the use of QR codes in Japan spread rapidly, and QR codes were used for various applications. It wasn’t long before the rest of the world caught on to the benefits of QR codes.

    Denso Wave Development

    Denso Wave developed the QR code to be unique from traditional barcodes on several fronts. The design of the QR code has three positioning squares that serve multiple purposes. The squares guide the scanning device, separate the data from the rest of the printed material, and maintain orientation. The positioning squares and the technology behind the QR code contribute to the sharpness and clarity of the code despite its small size.

    QR Codes Spread Globally

    Since the 90s, QR codes have gained acceptance rapidly, as they are easy to use, time-saving and their applications are endless. In recent years, QR codes have become particularly popular in other areas, such as social media, entertainment, and education. QR codes have caught on in many countries worldwide, and today they are used globally.

    QR Codes Today

    In today’s digital age, QR codes have a much wider range of applications than their inventors had initially imagined. Besides the traditional applications and uses seen in manufacturing and inventory management, QR codes have evolved to include educational purposes, enabling students to access web content with ease. QR codes have also become popular on social media, merchandise packaging, and even restaurant menus as a way of providing customers with more information.

    Future of QR Codes

    The future of QR code tech is looking bright. Companies are now trying to add more customization features to QR codes. The latest development is the colorisation of QR codes. Companies like Snapchat’s parent firm Snap have started experimenting with branded QR codes, pointing to a future of personalized QR codes. With the upgrade of smartphones and mobile devices, it’s essential for brands to create engaging content that resonates with their audiences. QR codes are an essential tool to achieve this, and it can be expected that there will be fresh innovations and further developments in this technology.


    QR codes may have originated in Japan as a simple concept for manufacturers, but it has evolved into a tool that has improved many business operations and opened the door to new technologies. QR codes have become an essential component of the mobile experience, and as the limits of the technology expand, it will undoubtedly continue to revolutionize the digital world in ways unimagined a few decades ago. As time passes, the use of QR codes has only continued to improve information exchange and interconnectivity, which will undoubtedly continue to shape the world around us.
