QR Code
QR, short for Quick Response, is a coding method. It can store more information and represent more data types than the traditional Bar Code.
Two-dimensional bar code (2-dimensional bar code) is a black and white graph that records data symbol information distributed in a plane (two-dimensional direction) according to a certain law with a specific geometric graph. In the code formulation, the clever use of the concept of "0" and "1" bit stream that constitute the logic basis of the computer, the use of a number of geometric forms corresponding to the binary to represent the text value information, and the automatic reading of the image input equipment or photoelectric scanning equipment to achieve automatic information processing: it has some commonalities of the bar code technology: each code system has its own specific
Character set
; Each character occupies a certain width; It has a certain verification function. At the same time, it also has the function of automatic recognition of different lines of information and processing of graph rotation change points.

The reading equipment and symbol generation equipment produced by equipment manufacturers in other countries have been widely used in various two-dimensional code application systems. As a new technology of information storage, transmission and recognition, two-dimensional code has attracted the attention of many countries in the world since its birth. The United States, Germany, Japan and other countries have not only applied two-dimensional code technology to the management of various documents by public security, foreign affairs, military and other departments, but also applied two-dimensional code to the management of various statements and bills by customs, tax and other departments. The management of commodities and goods transportation in commercial and transportation departments, the management of postal parcels in postal departments, and the automation management of industrial production lines in industrial production fields.
China's research on two-dimensional code technology began in 1993.

Two-dimensional code is a more advanced bar code format than one-dimensional code. One-dimensional codes can only express information in one direction (generally horizontal), while two-dimensional codes can be stored in both horizontal and vertical directions
Message
. One-dimensional codes can only be composed of numbers and letters, while two-dimensional codes can store information such as Chinese characters, numbers and pictures, so the application field of two-dimensional codes is much wider.
Two-dimensional barcode/two-dimensional code can be divided into stacked/row type two-dimensional barcode and matrix type two-dimensional barcode. Stacked/row type 2D bar codes are morphologically truncated by multiple lines
One-dimensional bar code
Stacked; Matrix bar code is composed of a matrix in the form of a "point" in the position of the corresponding element of the matrix
Binary system

Common code systems are:
PDF417 2D barcode
Datamatrix 2D barcode, QR Code, Code 49, Code 16K, Code one, etc., in addition to these common 2D barcodes, There are also Vericode barcodes, Maxicode barcodes, CP barcodes, Codablock F barcodes, field codes, Ultracode barcodes and Aztec barcodes.
Two-dimensional code applications can be divided into two categories according to different business forms: read and main read.
Read business
The platform will pass the QR code
MMS (MMS)
Send it to the user's mobile phone, the user takes the mobile phone to the scene, and scans the mobile phone through the two-dimensional code machine for content recognition. After the application party encrypts the business information and prepares the two-dimensional code image, the two-dimensional code is sent to the user's mobile terminal through SMS or MMS. The user can read and authenticate the two-dimensional code image on the mobile terminal through the special reading device located in the service network, which can be used as the certificate of transaction or identity identification to support various applications.
Primary read services
Users install QR codes on their phones
client
Use mobile phones to photograph and identify two-dimensional code pictures printed on media, newspapers, etc., obtain the contents stored in two-dimensional code and trigger related applications. Users use mobile phones to take images of QR codes containing specific information, through
Mobile client
After decoding, the software triggers a variety of associated operations such as mobile phone Internet access, business card reading, and phone calls, so as to provide users with various information services.

Transport of goods
When the barcode is damaged to a certain extent, error correction can enable the barcode to correctly decode the two-dimensional code. It is a multi-line, continuous, variable-length symbolic identifier that contains a large amount of data. Each bar code has 3-90 lines, and each line has a start section, a data section, and an end section. Its character set includes all 128 characters, with a maximum data content of 1850 characters.
One-dimensional bar code
Information is expressed only in one direction (generally horizontal), while no information is expressed in the vertical direction, and a certain height is usually for convenience
reader
The alignment of.
The application of one-dimensional bar code can improve the speed of information entry and reduce the error rate, but one-dimensional bar code also has some shortcomings:
Bar code
Relatively large size (low space utilization);
If the bar code is damaged, it cannot be read;
In both horizontal and vertical directions
Two-dimensional space
Bar codes that store information are called
Two-dimensional bar code
(dimensional bar code).
The PDF417 code is made by Wang Yinjing, a Chinese student in the United States.
Learned scholar
It was invented. PDF is an abbreviation of the first letter of the English Portable Data File, meaning "portable data file". Because each symbol character of the bar code is composed of 4 bars and 4 blanks, if the narrowest bar or blank of the bar code is called a module, the total number of modules of the above 4 bars and 4 blanks must be 17, so it is called 417 code or PDF417 code.

Macro PDF417 code
When the file content is too long to be represented by a PDF417 code, it can be represented by a macro PDF417 code containing multiple (1~99999) bar code blocks.
Although the application of two-dimensional codes is becoming more and more widespread, the development of two-dimensional codes in China is far from enough compared with countries such as Japan and South Korea. In addition to the support of operators, there are also constraints on technology, terminal adaptation, and profit models. What is very hot is the combination of two-dimensional code and O2O (Online To Offline) model, that is, the use of two-dimensional code reading to divert online users to offline merchants. Tencent is bullish on this model, Ma said, "QR codes are a key entry point for online and offline." Although some people are not optimistic about the application of two-dimensional code, there is no denying that as long as a sufficient number of users are cultivated, combined with a good business model, two-dimensional code will become one of the most effective tools to bridge reality and virtual.

3. Strong fault tolerance, error correction function.
5. Encryption measures can be introduced.
6. Low cost, easy to produce, durable.
According to the "Global Mobile Phone Security Report in the first half of 2012", 17,676 types of mobile phone malware were detected and killed in the first half of 2012, and two-dimensional code technology has become a new channel for the spread of mobile phone viruses and phishing websites.
Scanning the QR code sometimes brings up a link prompting to download software, some of which may contain viruses, according to police. Some of these viruses will affect mobile phones and tablet computers after downloading and installing; Other viruses are fee-sucking trojans disguised as apps that, once downloaded, cause phones to automatically send messages and charge large amounts of phone bills. In this regard, Hong Zhigang, a senior mobile phone software expert, believes that the use of two-dimensional code to defraud mobile phone bills is completely feasible, "in theory, the two-dimensional code itself will not carry.
virus
However, many virus software can be downloaded using QR codes. However, many mobile phones use open mobile phone platforms, if you download such virus software, it will 'occupy' the SMS sending interface of the phone, and send SMS messages without the user's knowledge. Such messages often require a deduction of 1 yuan or even 10 yuan, and the mobile phone bill is quickly lost before the user is unaware and goes into the pockets of the bad guys."
Relevant experts remind the public to raise awareness of prevention, before scanning to determine whether the source of the two-dimensional code is authoritative and credible, in general, regular newspapers, magazines, and posters of well-known shopping malls provide two-dimensional code is safe, but the two-dimensional code published on the website that does not know the source needs to be vigilant. Should choose a professional scan tool with monitoring function, scan to the suspicious website, there will be a security reminder. If you install the software through the two-dimensional code, after the installation, it is best to scan it with anti-virus software and then open it.
In fact, most of the malicious two-dimensional code is difficult to directly deduct the phone fee, but by luring the public to install the program to implement fraud. Be sure to read the installation instructions on your phone carefully. Don't go all the way just to make it easier.
Two-dimensional code security problems focus on two aspects of direct code scanning is dangerous

Qr codes will become the mobile Internet and
O2O
The key entrance. As e-commerce enterprises increasingly interact online and offline in parallel, two-dimensional code has become an important marketing carrier for e-commerce enterprises. The wide application of two-dimensional code in the field of e-commerce, combined with the concept of O2O, brings consumers a more convenient and rapid consumption experience, and becomes a new channel between online and offline e-commerce platforms, which is helpful for the extension of product information and horizontal price comparison.
Traditional O2O business model can lead online users to offline consumption, for merchants, this is more like a short-term online promotion activity, because users do not need to register before consumption as online, so for users such consumption is mainly a "one-time consumption behavior", more importantly, the front desk consumption data of offline merchants, In the traditional O2O model, there is no total database that can record these actual consumption data.

Its biggest feature is the uniqueness and safety, not only save costs, more importantly, save time to improve efficiency and easy to use, but also very environmentally friendly and fashionable.
How to efficiently detect the two-dimensional code: Before attending and exhibiting, the organizer only needs to send an electronic invitation (MMS, SMS) containing the two-dimensional code to the participants through the system, which contains the conference information as the exhibition check-in voucher. When signing in to the exhibition, participants only need to bring mobile phones to complete the signing in easily, bringing a new experience. At the same time, it also avoids the embarrassment of scrambling when the organizer checks the information on the spot, and it is very safe, effectively verifies the identity, and puts an end to false intruders. During the verification, the information of the participants is transmitted to the system database through the wireless communication system, so that the participation of the exhibition is clear and convenient for the statistical work of the participation after the exhibition. The whole process is fully electronic, and the mobile phone is used as the admission voucher, which realizes the information of conference attendance.

Fang drew a two-dimensional code with a pencil on the postcard. Through the two-dimensional code scanning software on his mobile phone, after many attempts, he swept out a simple love sentence: "Xiao Mori, I love you."
First of all, find a website that generates two-dimensional code online, type in the information to generate two-dimensional code, moderately enlarge the picture and print it out, draw the reference line, divide the two-dimensional code pattern into small squares, and label the small squares in the reference line, and then draw the 29×29 small square reference line on the postcard (depending on the specific amount of information). And according to the two-dimensional code number on the paper, the corresponding square is blackened, and finally the two-dimensional code can be verified by multiple software.
There is also a man from Changsha who works in Canada. When he returned home to visit his family during the Spring Festival, he met a girl by chance through a social software. The girl has a similar life experience with the man. Two people through a very occasional "shake", then began to know and love. The man even used the QR code to propose to the girl, and finally got the result.
The QR code created by 32-year-old Xu He in a wheat field in Botou, Hebei province, has been officially recognized by Guinness as the world's largest. The giant QR code measures 190 meters by side and covers a total area of 36,100 square meters, beating the previous record of 28,760 square meters held by a Canadian farm. The QR code, which can be scanned by a mobile phone, is linked to the team's wechat account. In April 2015, Xu He and his team carried out differential planting on nearly 100 mu of rented fields according to the proportion of two-dimensional code patterns, sowing wheat at different time nodes, and successfully created this giant two-dimensional code by using the color difference of wheat seedlings.

Tablet computer
The popularity of the application of the two-dimensional code has given rise to the application of the two-dimensional code, which was not optimistic before, and we compete to invest a lot of resources in technology research and development. Ma Huateng said: QR code is the mobile Internet entrance.
The application of two-dimensional code seems to penetrate into all aspects of our lives overnight, such as subway advertisements, newspapers, train tickets, airline tickets, fast food restaurants, movie theaters, group-buying websites and all kinds of commodity packaging. As a part of the Internet of Things wave industry, the application of two-dimensional code has never been so concerned, and some experts even predict that it will form hundreds of billions of market space in two or three years.
Internet of Things
Bar code, two-dimensional code and RFID are more commonly used by people, two-dimensional code is relatively one-dimensional code, with large data storage, good confidentiality and other characteristics, can be better combined with smart phones and other mobile terminals, forming a better interactive and user experience. Compared with RFID, two-dimensional code not only has a prominent cost advantage, but also has better application prospects for its user experience and interaction.
In the mobile Internet business model, the scope of people's business activities is wider, so it is more necessary to exchange and share information timely. With the popularity of smartphones and tablets in the 3G/4G mobile network environment, the application of two-dimensional code is no longer limited by time, space and hardware devices. Product basic attributes, pictures, sound, text, fingerprints and other information can be encoded and bundled, which is suitable for product quality and safety traceability, logistics warehousing, product promotion, business meetings, identity, material document identification and so on. It can realize timely tracking and tracing of material circulation through mobile network; Help with remote repair and maintenance of equipment; Product anti-counterfeiting, anti-channeling and end-consumer incentives; Enterprise supply chain process reengineering, etc., to further improve customer responsiveness and extend products and services to end customers. Manufacturers can also grasp the market dynamics in a timely manner, develop more practical products to meet customer needs, and ultimately achieve single-order production, which will greatly reduce production costs and operating costs.
With the country
Internet of things industry
It is believed that more two-dimensional code technology application solutions have been developed and applied to the daily business life of all walks of life, when the two-dimensional code has become a mobile Internet entrance really become a reality.
The application of two-dimensional code has the concept of main reading and being read. In foreign countries, the platform service of two-dimensional code refers to a platform for you to generate two-dimensional code, and attach a variety of information such as pictures, text, videos, etc. Essentially, the content of a QR code points to an address. So the two-dimensional code platform service belongs to the field of being read.
However, such a classification is too vague for users and the market, and the business model of the market two-dimensional code can be roughly divided into the following types:
1.
Information dissemination
. Whether it is electronic vouchers or museum, media or commodity information, in fact, is the concept of information dissemination, users can scan the two-dimensional code with their mobile phones, they can enter its corresponding address, and obtain complete data. The supplier establishes a completed business model by sending electronic certificates and laying the scanning hardware equipment to the local merchants.
2. Interactive entrance. For example, you can follow your wechat friends by scanning QR codes, or receive coupons, register for voting, participate in research and other operable forms on the phone, and send customer information back to the enterprise. Companies can maximize the effectiveness of advertising and gain valuable user interaction data. Such interactive buying patterns are already in place

And other fields began to use.
wechat
In earlier versions, QR code scanning service has been provided, users can directly establish wechat relationship by scanning the QR code of others. After version 4.0, wechat also provides the function of realizing the synchronization between mobile phone and computer wechat by scanning the QR code directly, which is a very clever combination of QR code and verification. Sina Weibo has also recently launched the production of two-dimensional code, scan the two-dimensional code can follow the Weibo and other functions.
In 2012, wechat launched a public platform open to enterprises and individuals, opening the era of "we media". At the same time, the use of two-dimensional code has reached an unprecedented height, and a scan and attention are almost all ways of promoting public accounts. More and more multimedia programs log in
Wechat public platform
(such as the Voice of the Chinese Dream), it is more convenient for the communication between viewers and the media, and by releasing the QR code of the account in the program, it has rapidly accumulated a large user base in a short time.
3. Form a purchase. This will take you directly to the product
E-commerce platform
, generate transactions (such as Sencho Kee).
The process that originally needed to go into a physical store or buy online can now be realized by scanning a QR code and completing the shopping payment process on a mobile phone. This approach can compensate for the need to consume in previously inaccessible Spaces. The cooperation between Alipay and Focus Media is that users only need to scan the photos on Focus Media
