With the rapid development of RFID technology and the continuous reduction of the production cost of RFID electronic tags, the application of RFID tag anti-counterfeiting technology has also been greatly popularized, and it has gradually appeared in various industries, such as transportation, ticket security, and commodity anti-counterfeiting .
The English full name of RFID is Radio Frequency Identification, that is, radio frequency identification technology. RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments.
The basic components of radio frequency identification technology include readers, antennas, and RFID tags. The reader is also called a reader. It is a device that reads and writes RFID tags. It mainly includes antennas, radio frequency front ends, and read and write control units. three parts. An antenna is a device that implements radio frequency signal space propagation and establishes a wireless communication connection between an RFID tag and a reader. RFID tags are commonly known as electronic tags (tags). They can be divided into two types: active (active) and passive (passive) according to the working mode. The internal structure of the RFID tag chip mainly includes four parts: antenna, radio frequency front end, tag control unit and EEPROM storage unit.
The common application frequency classification of RFID can be divided into three categories:
Currently, RFID tags commonly used for anti-counterfeiting of goods generally belong to the high-frequency band (13.56MHz), and follow the ISO-14443A protocol. There also have Low Frequency RFID Sticker Tag.
Application of RFID tags in the field of anti-counterfeiting and security
1. Advantages of RFID anti-counterfeiting technology
Compared with other anti-counterfeiting technologies such as laser anti-counterfeiting technology and special printing symbol anti-counterfeiting technology, the advantages of radio frequency identification technology (RFID) are that each tag has a globally unique UID number. Storage space can carry more encrypted information or store data information related to actual applications. From the perspective of security or application flexibility, RFID tag anti-counterfeiting technology has unparalleled advantages.
2.Application examples of RFID anti-counterfeiting technology
Ticket anti-counterfeiting: In public transportation and tourist attractions, fake ticket incidents often occur. Using RFID electronic tag tickets instead of traditional tickets, not only improves the circulation rate of people, but also plays a role in security and anti-counterfeiting.
Certificate anti-counterfeiting: Internationally, in passport anti-counterfeiting, electronic wallets, etc., such as embedding RFID tags in passport covers or certificates, such as the promotion and application of second-generation ID cards are typical representatives in this regard, this technology will soon be used in the management of important certificate issuance Is widely used.
Commodity anti-counterfeiting: Adding anti-counterfeiting labels in the process of product production and packaging is equivalent to providing a reliable way to identify the authenticity of products, which can protect the legitimate rights and interests of product manufacturers and consumers. On the other hand, the label itself has a storage function, so in some special applications, the label can also be used to store all key information during the life cycle of the product, providing convenience for the subsequent use of the product, not just for security purposes.
Tags are easy to understand in the application of ticket counterfeit and anti-counterfeiting. In the field of anti-counterfeiting of goods, the tag reader used by consumers can be a mobile phone with NFC function. In addition, there is a Warehousing RFID Sticker for warehouse management.
