RF card application case 1: electronic traceability
There are three kinds of traceability technologies: one is RFID radio frequency technology, which attaches a logo with a chip on the product packaging. The products can be automatically collected and read in and out of the warehouse and transported. The flow of products can be recorded on the chip. One is a two-dimensional code. Consumers only need to take a two-dimensional code through a mobile phone with a camera to query the relevant information of the product. The records of the inquiry will remain in the system. Once the product needs to be recalled, the message can be sent directly. To consumers, to achieve accurate recall; there is a bar code plus product batch information (such as production date, production time, batch number, etc.), in this way the production of the company does not increase production costs.
The electronic traceability system enables 100% bi-directional traceability of all batches from raw material to finished product and from finished product to raw material. The biggest feature of this system is the security of the data. Each manual input is backed up by the software in real time.
Application Case 2 of RF Card: Food Traceability
The use of rfid technology for traceability of food and medicine has been piloted in some cities, including Ningbo, Guangzhou, Shanghai, etc. The traceability of food and medicine mainly solves the problem of tracking food routes. If you find a problematic product, you can simply trace it. Until the root of the problem is found.
Application Case 3 of RF Card: Product Security
RFID technology has experienced decades of development and application. The technology itself is very mature. It can be seen everywhere in our daily life. The application of anti-counterfeiting is actually adding an RFID electronic tag to ordinary goods. The tag itself is equivalent to the identity card of a product. With the various links of production, distribution and use of goods, all kinds of information on goods are recorded in each link. The tag itself has the following characteristics:
Uniqueness
Each label has unique identification information, and the label is bound to the product information during the production process, and the label uniquely represents the corresponding item in the subsequent circulation and use.
High security
Electronic tags have a reliable security encryption mechanism, which is why today's second-generation ID cards and subsequent bank cards in China use this technology.
Easy to verify
Whether it is pre-sale, in-sale, or after-sale, users can verify it in a very simple way whenever they want to verify. With the popularity of NFC mobile phones, users' own mobile phones will be the simplest and most reliable ones.
Long shelf life
The average label storage time can be several years, ten years, or even decades. Such a storage period is sufficient for most products.
In order to consider the security of information, the application of RFID in anti-counterfeiting generally adopts the 13.56M frequency band label, and the RFID label cooperates with a unified distributed platform, which constitutes a whole process of product anti-counterfeiting system.
Although there are many advantages in RFID anti-counterfeiting, there are obvious disadvantages. The most important one is the cost problem. The cost problem is mainly reflected in the cost of labeling and the construction cost of the whole anti-counterfeiting system. The cost of labeling is generally more than one piece of money. For ordinary cheap goods. It is not realistic to say that it is necessary to use RFID anti-counterfeiting. In addition, the construction cost of the whole anti-counterfeiting system is relatively high. It is not that the average enterprise can afford to realize and promote it. It is more suitable for enterprises with small scale. Third-party RFID anti-counterfeiting platform. museum
(USA) The California Technology Innovation Museum is using RFID technology to expand and enhance the visitor experience. They give each visitor an RFID tag that allows them to view information about the show on their personal web pages in the future; this tag can also be used to determine the language in the list of directories visited by visitors to the museum. category.
Perhaps one day in the future, the US Museum of Technology Innovation will develop a display to detect the impact of RFID technology on the world. However, the museum in California is using RFID technology to expand and enhance the visitor experience. The museum was founded in 1990. Since its inception, it has become a famous and popular place to visit in Silicon Valley, and has attracted many families and technology enthusiasts to visit. It can receive about 400,000 visitors every year. From the positive and good response made by the visitors, the use of RFID tags was successful.
The museum will be a permanent exhibition of science and technology that contributes to human science, life sciences and communication, and will showcase the achievements of Silicon Valley innovators and others. A life sciences exhibition called "Genetics: Technology With a Twist" was held in March 2004. At this meeting, the museum showed the use of RFID tags, which means that each visitor visits an RFID tag. To enable it to view relevant information about the exhibition on its personal webpage in the future.
Due to the influence of other visitors and the time limit, visitors are not able to understand and learn more about the display as expected. By using RFID tags to automatically create personalized information pages, visitors can choose to search for relevant information on a display topic at a convenient time, or find relevant documents in the museum.
After the visit, visitors can also access the website via the Internet at the school or at home and type in a 16-digit ID number on their label and log in. This way they can access their unique personal web page. Many museums in the United States and other countries plan to use RFID technology on the same end of a card or badge. At least one natural history museum in Denmark handed the reader to the visitors in the form of a PDA and combined the label with the display. But according to Greg Brown, deputy director of the Museum of Technology Innovation, the museum is the first museum to use RFID technology wristbands.
Application Case 4 of RF Card: World Expo
The number of exhibitions held in Shanghai is increasing at a rate of 20% per year. The Shanghai Municipal Government has been actively exploring how to apply new technologies to enhance the ability of the group to better display the image of Shanghai. The application of RFID in large-scale exhibitions has been verified. In 2005, the ticket system of the Aichi Expo adopted RFID technology, which enabled a large number of visitors to enter the market quickly. The organizers of the 2006 World Cup also adopted tickets embedded in RFID chips, which played a role in anti-counterfeiting. This has attracted the attention of the organizers of large-scale exhibitions. At the 2008 Beijing Olympics, RFID technology has been widely used.

Ceiling Light
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
