The rapid development of the market economy has promoted the diversification and richness of market products, and fully satisfied the needs of consumers. But at the same time, counterfeit and counterfeit products and counterfeit goods have also appeared in large numbers, seriously affecting the interests of consumers and businesses. Mainly manifested in the alcohol, food, medicine and other industries, once product counterfeiting and substandard phenomenon occurs, it will bring immeasurable losses to society and individuals.
The production, circulation and use of these products require safe and effective counterfeit protection measures. For a long time, counterfeit and inferior products have not only severely affected the country’s economic development, but also endangered the vital interests of enterprises and consumers. In order to protect the interests of enterprises and consumers and ensure the healthy development of the socialist market economy, the country and enterprises spend a lot of manpower and financial resources on anti-counterfeiting and anti-counterfeiting every year. However, most of the anti-counterfeiting technologies used in the anti-counterfeiting products on the domestic market are still making fuss on paper-based materials. Its technology does not have uniqueness and exclusivity, and is easy to copy, so it cannot play a real anti-counterfeiting role. At present, the international anti-counterfeiting field has gradually emerged a trend of using electronic technology to prevent counterfeiting, especially the use of radio frequency tags, whose advantages have attracted widespread attention.
Radio frequency identification technology (RFID) is an automatic identification technology that emerged from the 1990s and gradually matured. It uses radio frequency for non-contact two-way communication to achieve identification and exchange data. The use of radio frequency identification technology for anti-counterfeiting, compared with other anti-counterfeiting technologies such as laser anti-counterfeiting, digital anti-counterfeiting, etc., has the advantage that: each label has a globally unique ID number-UID, UID is placed in the ROM when the chip is made , Cannot be modified, cannot be imitated; no mechanical wear, anti-fouling; the reader has a physical interface that is not directly open to the end user to ensure its own security; in terms of data security, in addition to the password protection of the label, the data part is available Some algorithms implement security management; there is a mutual authentication process between the reader and the tag.
RFID technical characteristics
◆ The global unique ID anti-counterfeiting chip cannot be modified or counterfeited;
◆ Flexible installation method ensures that the chip cannot be disassembled or transplanted;
◆ Easily realize the source traceability of the product (which manufacturer produces, which channel purchases and sells);
◆ Through the handheld reader, the authenticity of batches can be verified with manufacturers in any Internet access network;
◆ The chip has a built-in storage space of 96bit or greater, which can write manufacturer customized information and can be encrypted;
◆ Long-distance reading can be achieved through the reader, the fixed reader is 7~12 meters, and the handheld reader is about 2 meters;
◆ It can read more than 100 tags in batch within 1 second, speeding up logistics operation;
◆ Improve the existing warehousing process of the enterprise, which can realize automatic reading and automatic statistics of warehousing and exit;
◆ RFID collected data can be connected with the company’s existing application system.
Industry Application
At present, international and domestic breakthroughs have been made in the use of RFID technology for anti-counterfeiting applications.
● Document anti-counterfeiting
Internationally, in terms of passport anti-counterfeiting, electronic wallets, etc., RFID tags can be embedded in the cover of standard passports or documents. The chips also provide security functions and support hardware encryption, complying with the international standard of ISO 14443. A considerable scale of applications has also been formed in this field in China, and the popularization and application of second-generation ID cards is a typical representative of this aspect.
● Ticket anti-counterfeiting
In this regard, some applications urgently require RFID technology, such as in railway stations, subways, tourist attractions and other places where there are many people, using RFID electronic tickets instead of traditional manual tickets to improve efficiency, or compare ticket volumes in competitions and performances. In large occasions, RFID technology is used to prevent counterfeiting of tickets. Not only does it no longer need manual identification to realize the rapid passage of personnel, but it can also identify the number of times the ticket is used to prevent the ticket from being stolen and used again, so as to achieve “time anti-counterfeiting”.
● Anti-counterfeiting of medicines
Medicines are special commodities for preventing and curing diseases and ensuring human health, but there are often reports of the manufacture and sale of fake medicines in the media. With the deepening of the reform of the medical system and the implementation of drug classification management methods, the proportion of patients who choose drugs on their own has gradually increased, and supermarkets that mainly sell drugs have also appeared. The World Health Organization (WTO) Geneva Communiqué pointed out that more than 10% of drugs sold worldwide are counterfeit drugs. OTC medicines are special products that consumers can buy directly. If they are fake and inferior products, they will seriously affect the health of consumers and even endanger their lives. With the increase of pharmaceutical sales channels, it is urgent to strengthen the anti-counterfeiting of pharmaceutical packaging.
Radio frequency tags provide drugs with identification that can hardly be copied. Any medicine bottles that have been reported to be lost or sold will leave a record on the chip. The U.S. Food and Drug Administration will work with several major pharmaceutical companies to install micro-antennas on medicine bottles and use RFID technology to prevent counterfeiting of medicines. It is predicted that the application prospect of RFID anti-counterfeiting technology in the medical field is quite impressive.
● Packaging anti-counterfeiting
In order to combat counterfeiting, the American manufacturer of the anesthetic OxyContin announced that it will use radio frequency technology (RFID) on the medicine bottle. The realization of electronic monitoring of the whole process of medicines from production to pharmaceutical factories is an effective means to combat the growing phenomenon of medicine fraud. Drugs, food, dangerous goods and other items are closely related to personal safety in daily life, and are all special items regulated by the state. The process of production, transportation and sales must be strictly managed. Once the management is unfavorable and scattered to the society, it will inevitably pose a great threat to the safety of people’s lives and property. The Chinese government has also begun to try to use RFID technology to meet their needs with the help of leading domestic manufacturers in the field of radio frequency identification (such as Yapu Finove, etc.).
In addition to anti-counterfeiting functions, RFID tags also have outstanding features such as non-contact identification, identification of high-speed moving objects, resistance to harsh environments, strong confidentiality, and the ability to identify multiple identification objects at the same time, so it can be used in a wider range of occasions. In foreign countries, radio frequency tags have been widely used in many fields such as industry, commerce, transportation, logistics and so on. Its unique high accuracy and speed greatly reduce the logistics cost of the enterprise, and improve the market competitiveness and service efficiency of the enterprise.
