In fact, when it comes to health code, what we have to mention is QR code. Two-dimensional code is also called two-dimensional bar code, and the common two-dimensional code is QR code, which means rapid response. It is a very popular coding method in mobile devices in recent years, which can store more information and represent more data types than traditional bar codes.
? 2-dimensional bar code is a kind of black-and-white figure which is distributed on a plane (two-dimensional direction) according to certain rules and records data symbol information. In coding, the concepts of "0" and "1" bit streams, which constitute the internal logic foundation of the computer, are skillfully used, and several geometric figures corresponding to binary are used to represent the numerical information of characters, which can be automatically read by image input equipment or photoelectric scanning equipment to realize the automatic processing of information: it has some characteristics of barcode technology: each code system has its own specific character set; Each character occupies a certain width; It has certain verification function. At the same time, it also has the function of automatically identifying different line information and processing graphics rotation change points.
? Generally speaking, the application direction of QR code is mostly commercial activities, network connection and information acquisition. At the same time, it has the characteristics of large amount of information, easy identification and low cost, and the information acquisition, identification and low cost meet the requirements of health code.
The widespread application of health code was probably in the middle of 2020, but the concept of "health code" was actually put forward in February 2020. On April 29, 2020, the General Administration of Market Supervision (Standards Committee) issued an announcement and issued a series of national standards for "personal health information code". This series of standards adopted the quick procedure of national standards, and it only took 14 days from project establishment to publication. ? After the implementation of this series of national standards, the coding system, display mode and data content of personal health information codes can be unified, and the protection of personal information and the enjoyment and utilization of information can be considered as a whole, which is suitable for guiding the design, development and system integration of health code-related information systems.
? As we all know, there are three kinds of "health codes": the green code can pass directly, the red code is isolated 14 days, and the yellow code is isolated within 7 days. As a result, the health code system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places. In order to promote the mutual recognition of "health code" in different places, the national comprehensive government service platform provides three ways to realize cross-provincial mutual recognition and sharing. The first way is to add the cross-regional mutual recognition function to the local "health code" through the cross-regional epidemic prevention and health information data sharing without changing the existing local "health code". Second, the local "health code" is connected with the national comprehensive government service platform "epidemic prevention information code", and the national comprehensive government service platform "epidemic prevention information code" is used as the intermediary to realize the mutual recognition of cross-regional "health code". Thirdly, in areas where there is no local "health code", the "epidemic prevention information code" of the national comprehensive government service platform can be directly adopted, and at the same time, combined with local epidemic prevention and health-related information, cross-regional interoperability and mutual recognition can be realized.
? Of course, the "health code" still can't cover everything. For example, citizens' health information is usually uploaded by themselves; The use of health codes is very popular on mobile devices. If you are an elderly friend who lacks mobile devices or their experience, you may feel trouble. Many times, the health code is checked by people, and people in trouble like to use "screenshots" to "get away with it"; Of course, the human resources consumed by this kind of manpower inspection should not be underestimated. If HAMA Wisdom provides a solution, I will recommend our health code face recognition temperature measuring terminal, which not only can recognize quickly and accurately, but also can connect with various health code platforms. At the same time, it is equipped with personal authentication mode, which uses identity authentication when health code verification cannot be provided, so that other technologies can be used to assist the use of health codes, which can make the use of health codes more comprehensive.

? Recently, the epidemic has been close to normalization. Although from time to time there will be information that COVID-19 is fanning the flames in a certain place, it is still tinkering around the edges and was immediately suppressed by our United people. I believe that as long as we do a good job in daily protection, pay attention to personal hygiene and actively respond to the national epidemic prevention call, we will certainly be able to drive the epidemic out of our homes, and sincerely hope that the day of breathing freely in the sun will come back to us as soon as possible.
