1. Introduction to RFID technology
RFID (Radio Frequency Identification, referred to as RFID) refers to radio frequency identification, which is a non-contact automatic identification technology. The non-contact two-way communication between the RFID tag and the reader uses the energy of electromagnetic waves to automatically identify the target object and obtain relevant data. The technology proposed related theories in 1948. RFID technology was officially made public in 1975. Commercial applications began to sprout in 1980 and were widely used in various industries in 1990. Since 2000, it has been supplied by Wal-Mart and the U.S. military. RFID has been developed more vigorously due to the requirements of cargo merchants, and is known as one of the ten important technological projects of this century.
The international ISO organization has promulgated management standards for animal RFID, including three standards ISO 11784/11785 and 14223. ISO 11784/11785 specifies the code structure and technical guidelines for animal identification, while the ISO 14223 standard includes three parts: air interface, code and command structure, and application. It is an extended version of ISO 11784/11785.
2. Outstanding advantages of using RFID technology for animal identification
1. High-speed reading
RFID is an invisible transmission technology, that is, the reader can read it without “seeing” the mark, which means that the operator can operate without aligning the mark. As long as the RFID tag enters the effective reading range of the reader from 0 to 60CM, the swaying animal can be quickly and accurately read within 300 milliseconds from all directions and at any angle. It effectively solves the technical difficulties of reading under severe conditions such as animal shaking, and further guarantees the personal safety of operators in actual work.
2. Anti-pollution
In the breeding process, the RIFD logo worn by animals will be contaminated to varying degrees, which is difficult to avoid. The working frequency of the label is 134.2 Hz, and its low-frequency electromagnetic wave penetration ability is very strong. It can easily penetrate the contaminated surface of the label for non-contact reading without the need of light cooperation.
3. Anti-wear
RFID reading is to operate the RFID chip, and the chip is encapsulated in a logo with a thickness of about 4.48 mm and is very strong. The proper wear of the logo will not affect the normal operation of the chip.
4. Reusable
The traditional barcode identification information is static and cannot be updated. RFID technology can read and write to its chip repeatedly, the information is dynamic, can be updated, and the amount of stored information is large. The matching of the logo issuer and related software programs can ensure the uniqueness of the nationwide logo after repeated use of the logo, greatly reducing its long-term use cost.

According to a research report issued by an international market research company, it is estimated that between 2006 and 2010, the total output of RFID will double by 25 times, reaching 33 billion U.S. dollars. With the exponential growth of the RFID industry and the continuous advancement of technology, production and procurement costs will be greatly reduced. By 2010, the cost will drop to 5 cents. RFID has a lifespan of more than 20 years under normal use, and the cost is evenly distributed to each year and individual animals. The comprehensive use cost advantage is very obvious.
5. Brief introduction of the application status of RFID technology
At present, domestic RFID technology has been widely used in many fields such as second-generation ID cards, public transportation, railways, logistics, and communications. After the Chinese Ministry of Railways has applied RFID technology to the dispatch of railway vehicles, it has improved resource utilization and reduced management costs. The accuracy of its information and the time saved can bring direct economic benefits of more than 300 million yuan each year.
Wal-Mart, the world’s largest retailer abroad, has applied RFID technology to 1,000 of its 6,500 stores, covering 200,000 items and involving 600 manufacturers. RFID technology increased Wal-Mart’s revenue by US$285 million in 2004, and the International Article Numbering Association predicts that the use of RFID technology can save Wal-Mart US$8.35 billion each year.
In the field of safety production monitoring of agricultural and livestock products, RFID technology has also made considerable progress in recent years. In September 1998, the United Kingdom announced the RFID cattle tracking system plan. At the end of 1999, all EU member states also implemented this plan. Starting on November 1, 2003, the United Kingdom began to implement new pig identification standards. Beginning on August 30, 2004, the United Kingdom required RFID identification and tracking of horses. Starting from January 1, 2008, Europe is compulsory to implement RFID identification of sheep. The Australian government has promulgated the “National Livestock Product Certification Scheme” based on RFID technology, referred to as NLIS. The Beijing 2008 Olympic Games also put forward high requirements for food safety. Its meat product suppliers have applied RFID technology to track the breeding and slaughter links.
RFID technology has also played an important role in the refined production of livestock products. Take pig raising as an example. Without the use of RFID technology, the scale of the pig farm will increase by 10 times, and the cost will increase by 12 times, while the production will only increase by 8 times. After the adoption of RFID technology, the scale of the pig farm has been expanded, the production management has been strengthened, the body condition of the pigs has been significantly improved, and the production performance has been improved. At the same time, it saves 20% of feed, 20% of labor, and 15% of production. The economic benefits are very significant. .
According to statistics, in 2006, countries around the world used 70 million RFID tags for animal identification, and in 2007 it rose to 90 million. At the RFID International Summit Forum held in Beijing in 2008, some experts said that the United States will fully adopt RFID instead of bar code technology within three years. RFID technology is gradually developing into a pioneer in the post-barcode era, and currently it represents the highest level of animal identification technology.
Sixth, proposal
Combining the current status and development trend of international animal traceability, Beijing Tianshi Technology Co., Ltd., as the industry’s leading provider of wireless automatic identification solutions, has participated in the “Beef Product Quality and Safety” of the National 863 Program hosted by the National Agricultural Information Engineering Technology Research Center. Through practice and research on the basis of “full-process tracking and tracing method and system”, in line with the principle of conforming to the national conditions and in line with international standards, the different characteristics of RFID and barcode technology have been fully considered, from the perspective of technology, actual environment, and market. It is proposed that the RIFD mark is used for animal breeding, slaughter, and processing links, and the bar code mark is used for transportation, retail, and circulation links. RFID and bar code are integrated solutions that combine two automatic identification technologies.
Using the existing broad application basis of bar codes to realize the effective connection between the production, processing and circulation information of livestock products managed by the RFID system and users is to reduce the cost of RFID applications and adapt to the inevitable development direction of the globalization of the agricultural product market.
