What is a QR code?
Created on 11 August, 2022 | FAQ | | 6 minutes read
A QR code, short for Quick Response code, is a two-dimensional barcode that can contain information in the form of text, numbers, URLs, contact details, and more. It is a type of two-dimensional barcode that was originally developed in Japan in 1994 by the company Denso Wave, a subsidiary of Toyota. QR codes are designed to quickly and easily encode and decode information using a QR code reader, such as a smartphone, tablet, or QR code reader app.
A QR code consists of a pattern of black squares on a white background. The information is encoded through the position and arrangement of the black squares, which can form a more complex pattern than traditional barcodes. This allows QR codes to contain much more information than linear barcodes and can accommodate various types of data, such as text, URLs, email addresses, phone numbers, Wi-Fi settings, and more.
To use a QR code, a user can open a QR code reader app on their smartphone, scan the QR code using the device's camera, and view the decoded information or take actions based on the content of the QR code, such as visiting a website, adding a contact to the address book, making a payment, and so on. QR codes are widely used in various applications, such as marketing and advertising, ticketing, payments, authentication, logistics, and more, due to their simple and fast way of sharing information and enabling interaction between physical objects and digital content.
Rise and 'fall' of QR code
The QR code has had an interesting history of rise and "fall," evolving as a widely used technology for sharing information quickly and easily. Here is an overview of the major milestones:
- QR codes were first developed in 1994 by the Japanese company Denso Wave, a subsidiary of Toyota, as a way to quickly encode and decode information for the automotive industry.
- In the early 2000s, the QR code began to gain popularity in Japan, where it was used in industry and for consumer applications such as sharing contact information, promoting mobile websites and paying bills.
- With the growth of smartphones and mobile technologies, the QR code was increasingly used worldwide, especially in marketing and advertising campaigns, as it provided quick and easy access to online information.
- However, over time, the popularity of the QR code began to decline. This was partly due to some of the challenges and limitations of QR codes, such as the fact that they were sometimes perceived as inconvenient to scan, and that they were often associated with spam or malicious content.
- In addition, alternatives to QR codes have emerged, such as barcodes, NFC (Near Field Communication), and more advanced technologies such as augmented reality and beacons, which offer new ways to share information and create interactive experiences.
- This has led to a decline in the use of QR codes in some regions and applications, and has led to speculation about the "demise" of the QR code as a popular technology.
- Despite the challenges and alternatives, QR codes still remain popular worldwide in certain applications and industries. They are still used for marketing and advertising purposes, sharing contact information, linking to websites and social media, making payments, and more.
- Moreover, there have been some improvements and evolutions in QR code technology, such as the emergence of dynamic QR codes that offer more flexibility and tracking capabilities, and QR code scanners built into many smartphones, making QR code scanning easier and more accessible.
- In addition, the COVID-19 pandemic also contributed to renewed interest in QR codes as they were used for contactless payments, contact tracking for contact detection and other security measures.
In short, although the popularity of QR codes has varied over the years, they have recently seen a renewed rise due to the need for contactless interaction and improved user experience on smartphones. QR codes remain a convenient and versatile way to share information and interact with digital content.
Why is the QR code in the spotlight again?
The QR code is back in the spotlight for several reasons:
