As an advanced automatic identification and data acquisition technology, RFID technology is regarded as one of the top 10 technologies in the 21st century. It has broad application prospects in fields such as manufacturing and public safety. With the improvement of technology reliability and availability, it has gradually become an indispensable technical tool and tool for improving the level of logistics and supply chain management, reducing production costs, improving the level of public safety management informatization, and enhancing international competitiveness.
RFID technology is a revolutionary automatic identification technology that has inherited the concept of radar directly and developed accordingly. In the 21st century, with several large global retailers W aIMart, Metro, Tesco, etc., in order to increase the transparency and efficiency of the supply chain, they have announced their respective RFID plans and received the support of suppliers. Since then, RFID technology has opened up a huge new market. With the continuous reduction of costs and the unification of standards, RFID technology will also open up new markets in areas such as wireless sensor networks, real-time location, security and security, personal health, and product life cycle management.
The RFID system consists of the following components: An electronic tag, which consists of a chip and a tag antenna, communicates with the reader through the principle of inductive coupling or electromagnetic backscatter. 2 The reader/writer is a device that reads/writes tag information. As a terminal for data acquisition, the reader/writer also needs to exchange data with the middleware. 3 Antennas are devices that provide spatial propagation of radio frequency signals for tags and readers. 4 Middleware is the link connecting RFID devices and enterprise applications, and is also the core of RFID application systems. The principle is: First, the chip in the electronic tag is written with information representing the unique characteristics of the product, and this information is stored in the database of the server. When the product is close to the reader when the product is in circulation, the reader emits electromagnetic waves to provide energy to the electronic tag to activate the chip. The chip transmits the product information to the reader via the antenna, and the reader receives the information through the middleware. Passed to the server, the server processed and then passed the information to the reader to complete the confirmation of the product.
The principle of RFID determines its security, because the data of the tag is only a unique code and can be completely unencrypted. The data representing the special meaning corresponding to this unique code is stored in the security database. After reading the tag data, the reader sends the tag unique code to the security server. After the security server performs security verification on the request, it searches the database and retrieves the required data. The data is encrypted by the server and sent to the reader. In this way, as long as the attacker can not enter the database, malicious code information obtained is meaningless, without security verification will not get any useful information, product content and thus be protected. Comparison of RFID and barcode. Barcode information is visualized and easily copied. Because RFID carries electronic information, it is not easily copied.
At present, most of the anti-counterfeiting products used in the domestic market are still based on paper-based materials. Common anti-counterfeiting technologies include: holographic patterns, color-changing inks, and concealed markings on products and packaging. These technologies do not have uniqueness and exclusiveness, and often result in an anti-counterfeiting product or technology being copied shortly after its appearance. This will lead to forgery of anti-counterfeiting technology, prevention, and no real anti-counterfeiting effect. RFID technology application and anti-counterfeiting technology, its electronic tag is embedded in the chip and contains globally unique code or commodity code information. The code can only be identified by authorized reading and writing. At the same time, the tag information is communicated with the unique code of the reader through communication. The network is sent to the anti-counterfeit database server for authentication. In addition, when the label is damaged, the information cannot be read. This protects the contents of the label from being stolen, thereby achieving anti-counterfeiting.
Anti-counterfeiting in the Swiss watch industry uses RFID technology. Swiss W inwatch is committed to the development and application of intellectual property franchise patents and the application of RFID technology to a variety of Swiss watches, the patented franchise, taking into account the impact of the metal case on the antenna frequency, Wfinwatch will RFID tag Embedded in watch glass for watch security, identification and tracking. This technology has been certified by the Swiss government in 2003.
In the production process and product production, RFID is placed in the relative position of the product by manual or automated methods.
Anti-counterfeit labels, or put labels in product boxes. Before leaving the factory, the product's order number, production date, product model, and other valuable information written in the anti-counterfeiting RFID tag are combined with the ID number of the RFID tag to generate the unique information of the product and can be encrypted to prevent other The reader/writer changes the information in the tag. The RFID system located at the entrance of the warehouse automatically collects data and records where the batch of products is sent. In this way, the product achieves normal sales, reaches the customer through the seller or distributor. Because the information in the tag is encrypted during the factory write process, only the read/write device authorized by the manufacturer can read the encrypted information in the tag. If there is an activity of selling counterfeit products on the market, sales personnel use handheld sales inspection PDAs to read the information in the product labels.
It can determine whether the product is a product produced by the company and stop counterfeit products from flowing into the sales network in a timely manner. Such as: The use of RFID technology to achieve alcohol security system, is the use of RFID technology to achieve a combination of soft and hard anti-counterfeiting, this type of system can be used for the bottle with a container of goods anti-counterfeiting, through the bottle structure design and background certification system to achieve the goods Security. The system has a radio frequency chip embedded in the bottle cap and obtains product information through RFID readers, communication networks and anti-counterfeit database servers. The anti-counterfeit database server returns information such as the production date, manufacturer, query number, and the registrant-encoded registrant of the chip code to the RFID reader/writer, achieving the purpose of anti-counterfeit authentication. Finally, when the wine bottle is opened, the cutting device located at the bottle bottle mouth will cut off the connection between the antenna and the chip, so that the RFID reader cannot read the code of the top chip of the bottle cap, and can no longer be copied, thereby effectively To achieve the anti-counterfeiting of such goods.
After more than ten years of development, the rapid development of the anti-counterfeiting technology in China in recent years has reached a market scale of 10 billion yuan, and its absolute value is already quite large. However, the demand for anti-counterfeiting technology products will continue to grow in terms of the harm caused by counterfeit products in the industry. There are many types of anti-counterfeiting technologies, including printing anti-counterfeiting technology, chemical material anti-counterfeiting technology, physical anti-counterfeiting technology, digital information anti-counterfeiting technology, structure and packaging anti-counterfeiting technology, human body and biometric anti-counterfeiting technology. These technologies have been widely used in various fields, especially In the fields of currency, securities, documents, seals, medicine, food, cosmetics, clothing, agricultural products, auto parts, software and computer chips, etc., which are forged and infringed. The application of RFID in documents and anti-counterfeiting technology will be more and more, eventually forming an important area of ​​the RFID industry.
