With the maturity of large-scale integrated circuit technology, the volume of radio frequency identification systems has been continuously reduced, and radio frequency identification technology (RFID) has begun to enter the practical stage.
According to statistics, sales of RFID products worldwide have reached 685 million U.S. dollars in 1999. From 1992 to 1999, the average annual growth rate of RFID products in the world reached 25.3%. At present, several domestic companies have introduced foreign advanced technologies to develop their own radio frequency identification systems. Beijing Airport Expressway has used radio frequency identification (RFID) systems for automatic charging; Shanghai buses also use electronic monthly passes. There is no doubt that RFID technology will be applied in China. The main application areas will include AVI and traffic management, access control security, RFID card charging, production line automation, warehouse management, car security, electronic article surveillance systems, trains And identification of freight containers, of course, security is an important area of ​​RFID applications.
The application of RFID in the field of anti-counterfeiting has its own technical advantages. Anti-counterfeiting technology itself requires low costs, but it is difficult to counterfeit. The RF card itself has a memory, which can store and modify the data related to the product, which is beneficial to the use of the seller; the volume is very small and it is convenient for product packaging. Like computers, laser printers, televisions and other products can be used.
The establishment of a strict product sales channel is the key to the issue of anti-counterfeiting. Using radio frequency identification technology, manufacturers, wholesalers, retailers can use the unique product number to identify the identity of the product. In the production process, the incident frequency card is installed on each product, and the unique product number is recorded on the card. The wholesaler and retailer can use the reader provided by the manufacturer to strictly inspect the legality of the product.
Radio frequency identification technology is still in its infancy in China, but its development prospects are broad. In the near future, RFID technology will penetrate into our lives like other technologies and become a new economic growth point. From "Printing Technology"
