The electronic traceability system can realize 100% bidirectional traceability of all batches of products from raw materials to finished products and from finished products to raw materials. The biggest characteristic function of this system is data security, and every manual input link has real-time software backup. After decades of development and application, RFID technology itself is very mature and can be seen everywhere in our daily life. The application in anti-counterfeiting is actually to add an RFID electronic tag to ordinary goods. The label itself is equivalent to the identity card of the commodity, which records all kinds of information in every link of the production, circulation and use of the commodity. The label itself has the following characteristics: uniqueness. Each tag has unique identification information. In the production process, the label is bound to the commodity information, and in the subsequent circulation and use process, the label only represents the corresponding commodity. High-security electronic tags have a reliable security encryption mechanism, which is also the reason why the second-generation resident ID cards and subsequent bank cards in China adopt this technology. Verifiability Whether before, during or after sale, users can verify at any time in a very simple way. With the popularity of NFC mobile phones, users' own mobile phones will be the simplest and most reliable authentication devices. Long storage period. Generally, the storage time of labels can reach several years, ten years or even decades. This storage period is sufficient for most products.
In order to consider the security of information, the application of RFID in anti-counterfeiting generally adopts 13.56M band tags, and RFID tags cooperate with a unified distributed platform to form the whole process of commodity anti-counterfeiting system.
Although RFID anti-counterfeiting has many advantages, it also has obvious disadvantages, the most important of which is the cost, which is mainly reflected in the label cost and the construction cost of the whole anti-counterfeiting system. The cost of labels is generally above 1 yuan, so it is not realistic to use RFID for anti-counterfeiting of ordinary cheap goods. In addition, the construction cost of the whole anti-counterfeiting system is relatively high, which cannot be realized and popularized by ordinary enterprises. For small-scale enterprises, it is more suitable to directly use third-party RFID for anti-counterfeiting. California Museum of Science and Technology Innovation is using RFID technology to expand and enhance visitors' visiting experience. They give each visitor an RFID tag so that they can browse the relevant information of this exhibition on their personal web pages in the future; This tag can also be used to determine the language category in the catalogue list visited by museum visitors.
Perhaps one day in the future, the American Museum of Science and Technology Innovation will develop a display to detect the impact of RFID technology on the whole world. However, museums in California are using RFID technology to expand and enhance visitors' visiting experience. The museum was founded in 1990. Since its establishment, it has become a famous and popular visiting place in Silicon Valley, and attracted many families and technical enthusiasts to visit it. It can receive about 400 thousand tourists every year. Judging from the positive reaction of visitors, the use of RFID tags is successful.
The museum will permanently display the science and technology that have contributed to human science, life science and communication, and will show the achievements of Silicon Valley innovators in detail. In March, 2004, a life science exhibition named "Genetics: Twisted Technology" was held. In this exhibition, the museum showed the scheme of using RFID tags, that is, giving each visitor an RFID tag so that they can browse and collect the relevant information of this exhibition on their personal web pages in the future.
Due to the influence of other visitors and time constraints, visitors can't understand and learn more knowledge related to the exhibition as expected. By using RFID tags to automatically create personalized information web pages, visitors can choose to inquire about the relevant information of an exhibition theme on the web pages or find relevant information and documents in the museum at their convenience.
After the visit, visitors can also visit the website through the network at school or at home, and type the 16 ID number on its label and log in. So that they can visit their unique personal web pages. Many museums in the United States and other countries intend to use RFID technology on the same end of cards or badges. At least one natural history museum in Denmark gives readers to visitors in the form of PDA, and combines labels with display contents. But as far as greg brown, deputy director of the Science and Technology Innovation Museum, knows, it is the first museum to use RFID technology. The number of exhibitions held in Shanghai is increasing by 20% every year. The Shanghai Municipal Government has been actively exploring how to apply new technologies to improve the ability to organize meetings and better display the image of Shanghai. The application of RFID in large-scale exhibitions has been verified. In 2005, the ticket system of Aichi World Expo adopted RFID technology, which enabled a large number of visitors to enter the exhibition quickly. The organizers of the 2006 World Cup also adopted tickets with embedded RFID chips, which played an anti-counterfeiting role. This attracted the attention of the organizers of large-scale exhibitions. In the 2008 Beijing Olympic Games, RFID technology was widely used.
The 20 10 World Expo was held in Shanghai. Organizers, exhibitors, visitors, volunteers and other people have a large number of information service needs, including crowd guidance, traffic management, information inquiry and so on. RFID system is one of the effective means to meet these requirements. Organizers of the World Expo are concerned about the anti-counterfeiting of tickets. Exhibitors are more concerned about who has visited their booth, what contents and products they have, and the personal information of visitors. Visitors want to get the information they want quickly and find the content they care about. Anti-theft electronic tags have been widely used in medical care, libraries, shopping malls and many other aspects. However, I am still unfamiliar with some luxury goods in Zhuhai, because even if a small number of jewelry products are labeled with anti-theft electronic labels, it will only greatly improve the work efficiency of jewelry enterprises, such as taking stock, counting warehouses, putting them in storage, reducing the theft rate, etc., and will not have a particularly great effect on the holders who buy jewelry. What is needed is to add the tracking and positioning function after jewelry purchase, so that customers can not only wear jewelry with confidence in the future, but also locate jewelry information at the first time even if they accidentally lose jewelry. This will not only give customers a full sense of security, but also stimulate more people who have the ability to buy luxury goods to make up their minds to buy these luxury goods.
This kind of electronic tag can not only be used in jewelry, but also in the near future, such an upgraded version of electronic tag will emerge as the times require and be widely used in life.
RFID tags can be used in petroleum and petrochemical industry, State Grid, logistics, clothing and other fields. As long as valuable items can be supervised by RFID tags, even the transportation of personal items. It is not only a low-cost intelligent anti-theft product, but also an Internet of Things era that can be applied to real-time information management.
