The rapid development of market economy has promoted the diversification and richness of market products, which fully meet the needs of consumers. However, at the same time, imitation and counterfeit products also appear in large quantities, which seriously affect the interests of consumers and users. Especially those special products and items that are related to the people's livelihood, such as railroad materials, medical products and equipment, military materials such as guns and ammunition, industrial pressure vessels such as liquefied gas cylinders, once the product counterfeit and unqualified phenomenon, will bring incalculable losses to society and individuals. The production, circulation, use and maintenance of these special items require safe and effective anti-counterfeiting and tracking security measures.
In response to this demand, Tsinghua Tongfang has developed and launched the "RFID special item anti-counterfeit tracking system" application program using RFID (electronic tag) technology, and it has been successfully applied in the area of military supplies.
In the application of product anti-counterfeiting, RFID to its security, efficiency, speed, storage capacity, storage information change freely and other characteristics are known as a new generation of "electronic guardian". At the same time, RFID has the advantages of small size and strong functionality, can be strung through the product life cycle of multiple links, specifically in the following areas.
First, the product is anti-counterfeit. The anti-counterfeiting electronic label chip adopts digital anti-counterfeiting measures for the machine readable information. Using digital technology encryption, product information such as product name, product specification, manufacturer, production date, etc. are digitized and deposited into the electronic label machine readable chip. The electronic label will be attached to the product to ensure normal use in various environments. Using the tag reader for machine reading, the electronic tag anti-counterfeiting authentication and machine reading information security confirmation are completed, effectively playing the role of product anti-counterfeiting.
Second, authentication in the process of product circulation and use. Customers or authorized suppliers can quickly identify the authenticity of products, product model specifications and warranty years through a tag reader and a gentle shake on the product. It can effectively maintain the market order, improve the efficiency of product inspection and identification, save unnecessary disputes, protect the interests of authorized suppliers, and improve customer service.
Furthermore, the visualization of product warranty, maintenance and tracking is realized. Products have a certain service life, either short or long, and many different products together to form a complete system, the user is usually unable to know the use of each of them from the beginning to the end of time, resulting in the maintenance and repair of the system products become a passive work. Only when the product failure to know the product needs to be replaced, resulting in a loss of time and efficiency. If the products are managed using RFID, it will achieve the visualization of each product warranty, maintenance, and tracking. Customer maintenance staff in the daily inspection, just by tag reader in the product a light shake, you can quickly identify the product warranty years, when the expiration date, planned maintenance time and other information, will be a number of scattered information are unified to an RFID, saving staff time, reduce the cumbersome degree of product maintenance management.
The anti-counterfeit tracking system established by RFID technology can effectively improve the management of existing products, provide good service to authorized suppliers and end customers, and enhance the management service level of enterprises.
