Relevant statistics show that 10 billion QR codes are scanned every day in the world, and the application of QR codes in China accounts for about 90% of the world, with an average of more than 6 times per person per day.
As a "digital ID card" in the Internet of Everything era, QR codes are widely used in logistics and transportation, manufacturing, conference sign-in, mobile payment, catering services, asset management, marketing and other industries, and have become a common part of many people's lives.
Why are QR codes so popular in the Chinese market?
In addition to the development of habits such as scanning codes and payment, many experts and scholars are using QR codes as development tools, combining QR codes with the needs of work and life, and constantly exploring the application of QR codes in vertical industries. The innovative application of the two-dimensional code continues to explore the landing scene of the QR code with each academic paper.
QR code + medical care, a new idea for chronic disease management
According to data released by the National Health and Medical Commission, the number of people with chronic diseases in my country has reached 240 million, and it is expected to exceed 300 million by 2025. Management services for chronic diseases are already a rigid need, and there is an urgent need to find solutions that are low-cost, lightweight, and highly familiar to the public.
As early as around 2019, Ma Yamin and others from the Department of Thoracic Oncology Surgery of the Cancer Hospital Affiliated to the University of Chinese Academy of Sciences were discussing the application of grass QR codes in the health education of patients after radical esophagectomy. Randomly divided into two groups.
The control group used the traditional health education model, that is, the responsible nurses gave one-on-one face-to-face guidance and issued written health education sheets after the patients were admitted to the hospital, 1 day before the operation and after the operation; Face-to-face lectures and provide QR codes for scanning at any time.
The final experimental results showed that 75% of the patients in the observation group knew 80% or more of the disease knowledge, much higher than 37.5% in the control group. Ma Yamin and others wrote in "The Effect of Forage QR Code Health Education on the Postoperative Rehabilitation of Patients with Esophageal Cancer": Through oral education by nurses, patients and their families have a preliminary understanding of relevant knowledge, combined with scanning forage Consolidation and deepening of health education implemented by Weima will help to improve patients' mastery of health knowledge, improve their daily life ability and motor function, and enhance their self-management ability, thereby shortening postoperative recovery time and improving patient prognosis.
Also using QR codes for pathological knowledge education, there are also Jin Yangmei and others from the General Surgery Department of Taizhou Hospital in Zhejiang Province. They made relevant nursing knowledge into a video and put it on the QR code, encouraging patients and their families to scan the code to learn. And through the form of the second follow-up to understand the learning situation.
Jin Yangmei, after comparing the experimental results in "The Effect of Forage Two-dimensional Code Collaborative Management on Disease Knowledge and Self-care Ability of Patients with Preventive Enterostomy", believes that "As a new management method, two-dimensional code collaborative management can be used in problem assessment, It has a significant effect on intervention and effect evaluation, and can effectively improve the disease knowledge and self-care ability of patients with preventive enterostomy, and reduce the incidence of stoma complications."
The technical principles explored above are not complicated. The function of the QR code is to connect online and offline information portals. However, front-line medical workers creatively use QR codes to connect people and information, which reduces the cost of information reaching users. It not only releases the application potential of QR codes, but also enables every ordinary person to use QR codes. Codes solve problems and provide new ideas for chronic disease management.

QR code + teaching, release the imagination of interactive teaching
The reason why patients and their families are willing to scan codes to learn about information instead of written health education sheets is that QR codes have quietly changed the way we communicate with the world. It is no longer just a one-way acquisition of information, but derived from effective interactive information Propagate new paths.
Chen Dekang of the Guangdong Provincial Meteorological Technology Training Center developed a meteorological training QR code management application system based on the live code function of the forage QR code and combined with the business needs of Guangdong meteorological training without the participation of IT personnel. Realized the functions of training class sign-in, training class (meeting) registration, training information announcement, training video courseware download and viewing, etc.
Taking the sign-in in the training class as an example, the trainees participating in the training can use WeChat to scan the code to sign in, and use the form to collect information such as name, phone number, unit, location, etc. In order to prevent proxy signing, Chen Dekang required students to upload self-portraits on the spot, combined with the automatic recording time and location of the image watermark, to a large extent avoided the situation of others signing on behalf of others, not present at the check-in, etc.
As Chen Dekang shared in "Design and Implementation of Meteorological Training QR Code Management Application System": Meteorological Training QR Code Management Application System can not only automatically perform classroom attendance, but also expand the mobile phone learning function, which is convenient for students to use mobile phone learning materials. Manage and use to improve work efficiency.
Professor Cheng Xingguo from the School of Mechanical and Electronic Engineering, Guizhou University for Nationalities, designed an interactive teaching method based on mobile classrooms by using grass QR codes, rain classrooms and micro-classes, in which QR codes are used to urge students to preview. Professor Cheng will upload the next day's class content on the QR code in advance, and check the students' preview status in the management background through dynamic data statistics and other functions.
Professor Cheng Xingguo's "An Interactive Teaching Method Based on Mobile Classroom" was funded by the teaching reform research project of Guizhou University for Nationalities "Research on the Teaching Reform of the "University Computer Application Fundamentals" Course Combining Multimedia Fast Technology and App Application Technology", not only It improves and enriches teaching resources and teaching opportunities, and also plays a positive role in cultivating students' independent learning ability and sustainable learning ability.
There are actually many similar applications. Some people use two-dimensional codes to assist physics teaching, some use two-dimensional codes to manage chemical laboratories, and some people record plant DNA fingerprints and genetic relationships on two-dimensional codes... The two-dimensional code itself may only be used in classrooms. It is a tool for interactive teaching, but the application derived from the QR code, the solid innovation in every link of teaching and training, is constantly generating new value.

QR code + maintenance, can not only "go to the sky" but also "go to the ground"
If the application of two-dimensional codes in the medical field has tapped the potential of content display portals, the application of two-dimensional codes in the teaching field has broadened the imagination of two-dimensional codes and forms. There are also a group of engineers running on the production line. Two-dimensional codes and device management collided and sparked.
Zhao Qingliang is an engineer in the Maintenance Delivery Center of Shanghai Aircraft Manufacturing Co., Ltd. His main research direction is aircraft maintenance delivery assurance. Since the aircraft needs to use a lot of professional or even specially customized tools and equipment during the maintenance process, and the traditional equipment signs provide users with limited information, and the modification of the information is troublesome, Mr. Zhao built a set of aircraft using "live codes". Repair equipment using the maintenance system.
Focusing on the different needs of users, administrators, and engineers, Mr. Zhao records the instruction manuals, equipment files, and inspection and maintenance records of tools and equipment through "live codes". Equipment users can check the status and safety warnings of tools and equipment at any time; Equipment inspectors can receive online work cards, and after completing maintenance tasks according to the work cards, they can feedback pictures, sounds, and even video records in a timely manner; management engineers can update data in real time in the background of the system, monitor equipment status, and share the operating instructions of tools and equipment, equipment Effectiveness, maintenance and overhaul records, and reported repairs are updated in a timely manner, realizing multi-post linkage and systematic and paperless management of tools and equipment.
When Zhao Qingliang explored the application of QR codes in aircraft maintenance and delivery guarantee, Hao Longsong and others from Xincheng Gold Mine of Shandong Gold Mining Co., Ltd. used QR codes to design and implement an online equipment management mode suitable for trackless equipment in underground mines.
In the process of equipment management for many years, the mandatory maintenance management system of Xincheng Gold Mine’s trackless equipment adopts the method of manually filling in newspaper forms, but it is very easy to lose, dirty, and damaged during the transfer process, and it is limited by the driver. Writing ability, handwriting is often illegible, resulting in the need for a dedicated person to distribute, collect and report all the forms, resulting in low work efficiency and high labor costs.
Hao Longsong and others introduced the digital management method after using the two-dimensional code system in "Underground Mine Trackless Equipment Management System Based on Two-Dimensional Code Technology": No matter in the underground or in the mine, relevant operation and management personnel can log in to the system online in real time, reducing the The cumbersome procedures of inspection, document filling, and maintenance and repair record signing have improved the efficiency of maintenance and repair by nearly 10%. And through the system management background, real-time online statistics, export, and analysis of equipment management data can avoid the disadvantages of paper statistics, effectively avoid secondary entry, analysis and false data generation, and provide strong technical support for traceable equipment management .
