What is the QR Code module

The full name of QR Code is Quick Response Code, that is, quick response code. Two-dimensional code was first invented by a Japanese automobile company, they are mainly to solve the tracking problem of auto parts, with the rise of mobile Internet, two-dimensional code is widely used, making the application range of two-dimensional code module has also been rapidly expanded, but what is two-dimensional code? How does it work? This article will delve into the mystery of two-dimensional code.

A QR code is a matrix of black and white pixels arranged in a way that represents the encoded information, which can be read by a mobile phone or a special scanning device. The process of encoding and decoding information involves complex mathematical algorithms and computer science knowledge.

Compared with one-dimensional code, two-dimensional code can store more information, not only including numbers, letters, but also can encode different languages, text, website pictures and other complex data, it through Reed-Solomon error correction algorithm to ensure the reliability of the data, even if part of the damage can be fully restored. At present, organizations such as the International Association of Automatic Identification Manufacturers (AIM) and the International Standards Organization (ISO) have recognized the standards and applications of QR codes.

The application of two-dimensional code module is extensive and diverse. In the commercial field, two-dimensional code module is widely used in commodity tracking, inventory management, electronic ticketing, etc. In the field of public services, such as public transportation systems, two-dimensional codes can also be seen, and in our lives, two-dimensional codes are ubiquitous, whether it is payment, shopping, sharing personal contact information, scanning web pages, downloading applications, etc., there are it.

In the future, the development of two-dimensional code module will continue to change the progress of technology and the needs of users, enhance the combination of AR technology and two-dimensional code, can provide a richer interactive experience, and the development of encryption technology will enhance the security of two-dimensional code. At present, some experts predict that the future two-dimensional code may integrate more sensor functions, such as temperature and humidity monitoring, and further expand its application field. At the same time, with the rise of the Internet of Things (IoT), QR codes are expected to become an easy means to connect various devices.

Now the two-dimensional code module has become an irreplaceable tool has become inevitable, it not only changes our way of shopping, information access, but also promotes the efficiency of all walks of life and innovative development. And with the continuous progress and improvement of technology, the application of two-dimensional code module will be more extensive and in-depth, and the two-dimensional code module will play a more important role in the future. This small black and white grid will bring more convenience and fun to our life.
