Moreover, simple technology will develop rapidly in the future, and this thing will be used.
I personally think that good industries are only for reference.
What exactly is a QR code? In fact, it is an "upgrade" product of bar codes that are often used in shopping malls. Through it, computers can easily input commodity information. Barcodes used in shopping malls are called "one-dimensional codes" in the industry. In use, people found its limitations and gradually improved them. At present, two-dimensional codes were born on this basis. "In fact, they are collectively referred to as bar codes, and bar codes are a very important aspect of automatic identification technology. In automatic identification technology, in addition to bar code, there are magnetic card technology, sound and visual recognition, IC card technology and so on. For example, the transportation card used in the subway and the door card to enter the designated company are the application of automatic identification technology in life. As for its function, it is like the "eyes" of a computer, from which information that needs to be recognized can be easily entered into the computer system. "Haina" commodity information, but compared with other automatic identification technologies, bar code can be said to be the most economical and practical automatic identification technology so far. Its advantages are: fast input speed, high reliability, flexibility and practicality, easy manufacture of bar code labels and large amount of collected information. The traditional one-dimensional bar code can collect dozens of characters at a time, and the two-dimensional bar code can carry thousands of characters, and it has certain automatic error correction ability. Barcode has a unique advantage in the field of mass consumption. Barcode can record a lot of information, such as the country of production, manufacturer, product name, date of production, book classification number, starting and ending place of mail, category, date and so on, so it has been widely used in many fields such as commodity circulation, book management, post and telecommunications management, banking system and so on. As an "upgraded version" of barcode (one-dimensional code), one-dimensional code VS two-dimensional code is different from one-dimensional code. This paper makes a comparison from the aspects of appearance, identification and application. ● One-dimensional appearance code: black and white rectangular stripes with different thicknesses, usually with English characters or numbers under the stripes. Two-dimensional code: Black-and-white dot matrix graphics with different thicknesses, and Longbei code also sets the shape ratio at will. ● Principle One-dimensional code: Identification is determined by the different intervals between black and white parallel lines. Two-dimensional code: store information through different black and white points. ● Identify one-dimensional code: you can quickly know the basic information of the identified object, such as the name and price of the goods. But the one-dimensional code can only identify the goods, but can't describe the goods, just as it knows the code of an item in the computer, but it can't be sure whether it is "Zhang San" or "Li Si" or the difference between them. Two-dimensional code: it can not only identify, but also easily describe the object information. For example, when it is applied to a certificate, the information such as the name, age and even position of the holder of the certificate, whether he has a criminal record, etc. are quickly displayed in the computer after being scanned by the relevant equipment, and there is no need to wait for the computer database to confirm these information like a one-dimensional code. ● Advantage one-dimensional code: 1, which is widely used at present, especially in the field of mass consumption. 2, the cost is low, and the price of an instrument for identifying one-dimensional codes is only a few hundred yuan. At the same time, the technology continues to mature, and now there are national standards. QR code: 1, high density. The information density of bar code is improved by using the vertical dimension. Usually, its density is dozens to hundreds of times that of one-dimensional bar code, representing thousands of bytes of data. In this way, we can store all the product information in a two-dimensional bar code, so there is no need to establish a database in advance. 2, with error correction function. The error correction function enables the QR code to be correctly read when it is partially damaged due to perforation, fouling, etc. 3, do not erase. Once the data is stored in the QR code, it cannot be modified again. Among many automatic identification technologies, only two-dimensional code has this specialty, so it is very safe and reliable. 4, can represent a variety of words. Besides numbers and English characters, QR codes can also encode many languages. For example, QR code can encode Japanese characters, while Romberg code can directly encode Chinese characters. In addition, the QR code can also digitally encode photos, fingerprints, palm prints, sounds and other content. ● Disadvantages One-dimensional code: 1, which can contain less information, only dozens of characters, and can only use English characters or numbers. 2, the application needs to be combined with the computer database. QR code: 1, although the production cost is low, the scanning equipment is expensive. 2. At present, many domestic enterprises use foreign two-dimensional code system, but the high licensing fee may be as high as several million dollars. Relatively speaking, the two-dimensional code system developed in China and with the world's advanced level-Longbei Code-does not have this problem. ● Application of one-dimensional code: Posts and telecommunications, banks, chain stores, libraries, transportation and major enterprises and institutions are widely used. Two-dimensional code: At present, foreign developed countries are widely used in banking, logistics, national defense, customs, taxation, public security, transportation, civil goods and other fields. For example, Japanese QR codes can often be seen on Japanese auto parts, and American Data Matrix codes are more widely used in electronic products in Europe and America. China's own two-dimensional code, Longbei code, has been widely used in document anti-counterfeiting, product anti-counterfeiting and anti-smuggling and electronic ticketing, and is being popularized in 127 airports and the whole army. The difference between Longbei QR code map and other domestic companies that represent foreign QR code products is that Shanghai Longbei Information Technology Co., Ltd. is the only enterprise in China that has mastered the core technology algorithm and can independently develop related products. Therefore, Longbei code is a technology that Chinese people completely own intellectual property rights. It is compatible with a variety of two-dimensional code standards at home and abroad, and can be encoded in many different languages. A mutual translation system that can use up to 32 languages is designed. Romberg code can be encoded in not only multiple languages, but also multiple languages. That is to say, it is allowed to encode in more than two languages at the same time in the same Lombard code. Longbei code is based on English or Chinese as the resident system, and at the same time, one other language can be selected and applied. For some countries that use a single language, such as China, English-Chinese and Germany, English-German can be used. This function is of great value especially in the application of identity recognition system.
