With the popularity of smart phones and scan code software, the two-dimensional code industry is gradually emerging. Compared with the traditional one-dimensional bar code technology, the two-dimensional code has a large amount of information and a low technical threshold, which has become an important channel for connecting online and offline. At the same time, issues such as frequent security risks, inadequate industry supervision, and lack of standards have also had an adverse impact on the development of the industry. If you love it and care about it, come and comprehend it with Xiao Bian.
Hi, demand rich applications and more things <br> <br> as one of the core technology layer perception, two-dimensional code technology has been widely used in people's livelihood. You must have heard about the application of QR code technology to product traceability. For example, fruit growers will paste two-dimensional codes on apples, pears, and other fruits, and customers will use mobile phones to get a clear picture of the fruit's origin, growing environment, and other information. In addition to the traceability of the goods, more scenes include advertisements, coupons, etc., and placing two-dimensional code orders, and even many tourist attractions have begun to support two-dimensional code electronic tickets.
Research shows that there are dozens of application scenarios for two-dimensional codes, and most of them are related to people's livelihood. Xiao Bian learned that two-dimensional codes can also be used to manage production, perform quality control, and are widely used in product manufacturing processes. For example, in the automobile manufacturing, the direct part marking QR code has now been widely used in the automotive industry. From the engine's steel body, steel cover, crankshaft, connecting rod, camshaft to the transmission body, valve seat Bonnets, key parts of the clutch, and electronic ignition and airbags. Therefore, the use of two-dimensional technology in production and manufacturing can enable full tracking of production and processing quality, turning the original production line into a flexible production line, producing a wide range of products, and providing a complete data platform for the implementation of MES (Manufacturing Execution System) management. .
Anger, lack of supervision low standard <br> <br> you every day playing micro letter "sweep swept away", may not know that these two-dimensional code, mostly in Japan and the United States QR code PDF417 code. Have you ever heard our country's Hanxin, Longbei, GM, and CM? The root cause is the lack of standards, which makes our country lack the initiative in the two-dimensional code technology. China's two-dimensional code industry is in a state of disorderly competition. As China has not yet formed a unified top-level coding and analysis system, two-dimensional codes between different code standards and different application systems under the same code standard are difficult to achieve interconnection and interoperability. For example, the food safety traceability system, because there is no uniform coding system, will not be able to achieve integrated traceability.
“Compared to the developed countries, China’s two-dimensional code market and industry are in a state of fragmentation and disorder; there are still some fundamental and even fatal problems.†Deputy Director, Industry Department, Ministry of Industry and Information Technology Promotion Department Yang Zhigang said. The so-called network information security is not to mention mention. Therefore, some experts believe that in the era of big data, China must strive to resolve the interoperability of different code systems as soon as possible to strengthen China's voice in the two-dimensional code technology standards, do top-level design of the Internet of Things, and achieve "autonomy, security, and standardization."
Because of the lack of standards, there will be gaps in supervision. According to industry insiders, the current registration of a two-dimensional code company does not require special professional qualifications, and there is no provision for the production and distribution of two-dimensional codes, resulting in its original state of “anyone can produce and use it for printingâ€. . The experts strongly appealed that relevant departments should crack down on the use of two-dimensional code technology to spread viruses and steal phone bills.
Sadness, lack of security and more criticism <br> market <br> mentioned earlier the most popular QR code is said to be an open source two-dimensional code, anyone can freely download and change the information. At present, China has not yet formed a unified industry standard related to two-dimensional codes, leaving room for security breaches. Lawless elements can use it to induce consumers to download virus-laden software. According to the "Global Mobile Security Report for the First Half of 2012", 17676 mobile phone malware were found in the first half of 2012, and the QR code has become a new channel for mobile virus and phishing websites. So, you can always hear about the negative sound of the QR code.
Technically speaking, the two-dimensional code has a large amount of information, but this is a double-edged sword. We can obtain more information through the two-dimensional code, and it may also be because of this small two-dimensional code. Leaked personal information. For example, two-dimensional codes that can store personal information are now available on train tickets. Not long ago, news that passengers used illegal information to obtain information on passengers because they were discarded at random and used by criminals. The two-dimensional code has good encryption, so for two-dimensional codes with personal information or important information, we need more perfect encryption measures to ensure the security of information within the two-dimensional code.
Music, the advantage is still less rivals
Although people have different attitudes towards the advantages and disadvantages of two-dimensional codes, it is undeniable that this technology has been integrated into our lives. Tencent Ma Huateng once commented on the two-dimensional code: "It is the geographical location information of the mobile Internet that brings O2O (onlinetooffline online to offline), and the two-dimensional code is the key entrance of O2O." The important role of the two-dimensional code is obvious.
For the Internet of Things, its application is naturally more inseparable from automatic identification. Barcodes, two-dimensional codes, and RFID have all been widely recognized. Among the three, the two-dimensional code is relatively one-dimensional and has the characteristics of large data storage capacity, good confidentiality, etc., and can be better integrated with mobile terminals such as smart phones, resulting in better interactivity and user experience; Compared with RFID, two-dimensional codes not only highlight cost advantages, but also have unique application prospects for their user experience and interaction.
What is not symmetrical about this kind of advantage is that the equipment for identifying QR codes in the market is not rich enough. For the average user, besides the mobile phone or the mobile phone, the more professional decoding devices currently include handheld and stationary scanning guns, and not only the mobile phones with cameras in our hands. The two-dimensional code industry also has a variety of inherent advantages. Its industrial chain is short enough and there are many application scenarios. It is easy to stimulate the business explosion of two-dimensional code reading equipment companies.
