Who Invented QR Code?

QR code was invented in 1994 by a Japanese company called Denso Wave. The purpose of creating QR code was to create a more efficient way to track vehicles in factories. The company wanted to develop a system that could store more information than a traditional barcode and could be scanned at high speeds. Hence, they invented the QR code which stands for “quick response” code. Today, QR codes are commonly used for various purposes such as advertising, product information, event tickets, and payments.

Who Invented QR Code?

The Origins of QR Code

The QR Code was developed by Denso Wave, a Japanese company, in 1994. The original purpose of the QR Code was to improve efficiency in the automotive industry. It was designed to allow for fast and accurate tracking of parts and vehicles. The QR Code quickly proved to be an effective method for storing or retrieving data.

The Invention of QR Code

Masahiro Hara, an engineer at Denso Wave, is credited with inventing the QR Code. Hara wanted to create a code that could store more information than a traditional barcode. He designed the QR Code to be able to be scanned in any direction, making it easier to use. Hara’s invention would soon prove to be a game-changer in the manufacturing industry.

The QR Code addressing system was released as a learning aid in Japan in 1997, with an intention to provide a better learning experience in classrooms and educational materials. In 2002 QR codes became widely used for mobile phone payment systems in Japan.

The Evolution of QR Code

Since its creation, QR Code technology has continued to evolve. Denso Wave has released a variety of different versions, such as Micro QR Code and Frame QR Code. These variations are designed for different uses and can store various amounts of information. QR Codes have gained popularity across a range of industries, including advertising, education, healthcare, and many others.

QR Code technology allows for businesses to convey a multitude of information to their customers quickly. Scanning a QR Code can take a user to a website, a product demonstration, a menu, or even a payment portal. QR codes have revolutionized the way businesses connect and interact with their consumers.

The Enduring Popularity of QR Code

The QR Code continues to be a popular tool for businesses, due to its versatility and cost-effectiveness. One of the major advantages of QR Codes is their ability to store and retrieve vast amounts of data. They can store much more information than traditional barcodes and can be used for a variety of purposes.

The QR Code is now a global phenomenon, with billions of codes being scanned every year across countless industries. From factory floors to grocery store shelves, QR Code technology has changed the way businesses operate, communicate, and interact with their customers. Its invention was a revolution, and its ongoing evolution promises to keep it relevant for many years to come.

How Does QR Code Work?


QR Code or Quick Response Code is a two-dimensional barcode that consists of black and white squares arranged in a square grid pattern on a white background. The code was first invented for the automotive industry in Japan in the mid-1990s but has since found its way into various applications, including advertising, e-commerce, and payment transactions.

The Components of QR Code

A QR Code comprises several components that make it functional and useful. The code’s basic structure is a square grid pattern of black and white squares, also known as modules. The number of modules determines the amount of data that the code can hold. Additionally, there are three square alignment markers that help scanners identify the orientation of the code and adjust accordingly. The quiet zone, a margin area around the code, ensures that the code is scannable by separating it from any visual clutter.

The Encoding Process

QR Codes can store different types of data, including alphanumeric and binary data. Before encoding, the data is converted into binary code, usually using ASCII code. The encoding process involves arranging the binary code sequence into the QR Code matrix. The matrix is composed of patterns of black and white modules arranged in a specific way. When scanned, the pattern of the black and white modules corresponds to the sequence of binary data stored in the code.

The Decoding Process

To access the data stored in the QR Code, a QR Code scanner app is required. The scanner app captures an image of the code using the camera on the device. The app then identifies the square alignment markers in the code and determines the orientation of the code. From there, the app processes the pattern of the black and white modules and decodes the binary data. Finally, the app converts the binary data into readable data that the user can understand.

In conclusion, the QR Code is a versatile tool that has many applications in our daily lives. It is easy to use, and encoding and decoding data are quick and straightforward processes. While the code’s basic structure remains the same, it continues to evolve, and new applications and uses are being discovered daily.

QR codes were invented in 1994 by Denso Wave, a subsidiary of Toyota. To learn more about the people behind some of the world’s most innovative inventions, check out our pillar article on who invented artificial intelligence.

Who Invented QR Code?

QR Code, which stands for Quick Response Code, is a two-dimensional barcode that was invented by a Japanese company named Denso Wave in 1994. It was created to improve the efficiency of manufacturing processes and inventory management in the automotive industry.

The inventor of QR Code is Masahiro Hara, who worked as an engineer at Denso Wave at the time. He led a team of designers and engineers who developed the code to address the limitations of the existing barcode technology in use at that time.

Advantages of QR Code

QR Code offers several advantages that have made it a popular tool for various industries. Here are some of its advantages:

Disadvantages of QR Code

Despite its advantages, QR Code also has some disadvantages that should be noted. Here are some of the disadvantages:

Low User Adoption Rate

One of the main disadvantages of QR Code is its low user adoption rate, especially among older generations. Many people still don’t know how to scan QR Codes, which limits its effectiveness. This has been changing rapidly over the years with the increased use of smartphones and advancements in technology.

Limited Compatibility with Older Smartphones

QR Code is not compatible with older smartphones that lack QR Code readers. This limits the reach of the code and makes it harder to implement. This is why businesses and organizations need to ensure that their target audience has access to a smartphone with a QR Code reader before implementing it.

Vulnerability to Hacking and Phishing Attacks

QR Code can be vulnerable to hacking and phishing attacks, where scammers can create fake QR Codes that lead to malicious websites or malware. This is a risk that both users and businesses need to be aware of, and precautions should be taken to prevent such attacks.

Ways to Maximize the Benefits of QR Code

To maximize the benefits of QR Code, businesses and organizations should take the following steps:

Ensure that QR Codes are Easy to Scan

QR Codes should be placed in a location that is easy for users to scan and read. They should also be large enough to be scanned by older smartphones that lack a high-resolution camera.

Provide Valuable Information or Rewards to Users

QR Codes should provide valuable information or rewards to users to entice them to scan it. This can be in the form of discounts, giveaways, or access to exclusive content. This will increase the adoption rate of QR Codes and promote engagement.

Integrate QR Codes into a Larger Marketing or Communication Strategy

QR Codes should be integrated into a larger marketing or communication strategy. This will ensure that they are used effectively and reach their target audience. They should be part of a cohesive campaign that conveys a clear message to the users.

In conclusion, QR Code is a versatile and effective tool for businesses and organizations. Its inventor, Masahiro Hara, created it to improve manufacturing and inventory processes, but it has since evolved to have a wider range of applications. Although it has some disadvantages, the benefits of QR Code can be maximized by ensuring that it is easy to scan, provides valuable information or rewards, and is integrated into a larger marketing or communication strategy.
