RFID technology applied to food electronic labels

According to reports, the radio frequency identification (RFID) technology solution for ticket security and security tasks of the World Expo will be successfully implemented. The next year will be moved entirely to the Xi'an International Horticultural Exposition. The first single application of Shanghai RFID technology to the “post-World Expo” has been implemented. Shanghai Radio Frequency Identification Engineering Technology Association was also established recently.

At the same time, the global recall of Abbott’s milk powder has once again become a focus of food safety. The General Office of the State Council recently issued the "Notice on Further Strengthening the Quality and Safety of Dairy Products" and proposed the "Establishment of Electronic Information Traceability System". This is the first industry-wide application of electronic labels. Electronic labels are gradually becoming popular. It can be expected that electronic labels will play an even more important role in the supervision of food and drug safety, e-ticketing and logistics.

Electronic tags enter the life from the Olympics

RFID (Radio Frequency Identification) is a non-contact automatic identification technology. It automatically recognizes target objects and obtains relevant data through radio frequency signals. The identification work can be performed in various harsh environments without human intervention. It can identify high-speed moving objects and can identify multiple labels at the same time, and the operation is quick and easy.

The e-tag is well-known as it was at the 2008 Beijing Olympics. The e-tickets completed the anti-counterfeiting and security tasks well, making the advantages of radio frequency identification technology known to the general public.

At the summit on security and anti-counterfeiting technology for cards and certificates held in August this year, Zhang Xu, chairman of Chinabill Guoding, elaborated on the characteristics of RFID tickets: uniqueness; large amounts of storage; information on ticket holders and event holders With readable and writable functions, it can realize full digital management and status tracking from ticket printing, logistics and distribution, sales to ticket checking, and has an automatic ticket checking function, which not only improves the efficiency of admission, but also prevents loopholes such as human vote; automatic statistics, Give the organizers convenience.

From this we can see that the electronic tag has outstanding advantages in application. At present, e-labels are moving from the large-scale tournament exhibitions to the daily lives of ordinary people. In the future, e-tags will be widely used in food manufacturing, logistics and other fields to bring more convenience to businesses and consumers.

"Milk powder ID" or into a chance

Recently, problems with milk powder emerged in an endless stream, once again sounding the alarm for food safety.

Electronic tags can play an important role in regulating food safety. On September 25, the General Office of the State Council issued the "Notice on Further Strengthening the Work on Quality and Safety of Dairy Products" and proposed the "Establishment of Electronic Information Traceability System", requesting the completion of the electronic information tracing of infant formula milk powder and raw milk powder by the end of 2011. The establishment of system construction and related standards and regulations, and the gradual introduction of electronic information traceability systems in the dairy industry."

At present, the electronic information traceability system mainly uses the electronic tag technology. In fact, electronic labels have long been widely used in livestock husbandry and other industries and food safety, but they have been difficult to promote in China because of lack of mandatory policies and high costs. This milk traceability electronic information system is the first mandatory policy, which will play a key role in the promotion of electronic labels in various industries in China.

Some people think that if the establishment of an electronic information traceability system in the dairy products industry is successful, this will bring opportunities for the large-scale promotion of electronic labels in China, and the two industries related to the national economy and people's livelihood will most likely be used as the RFID industry. The breakthrough in development.

The prospects are broad and the policy needs to be pushed

In the era of rapid development of the Internet of Things, the application of electronic tags is very promising.

Electronic tag is essentially an identity authentication that can truly achieve "one thing, one code." RFID technology saves a lot of manpower while avoiding the interference of human factors. Through the combination of computer technology, network technology, and database technology, it can track products from production to sales and master the dynamic information of products in real time. This has a significant effect on product quality supervision, improving warehouse management, data detection and statistics.

China is a big manufacturing country, and electronic labels can almost completely replace bar codes in the production process. Since most of its applications in the manufacturing industry are closed-loop applications, the chips are recyclable and reusable, and the more the application, the lower the cost. Therefore, the electronic label has a broader outlook in the manufacturing industry.

However, the electronic tags used in the consumer goods retail sector are mostly one-off and are easily subject to cost constraints. However, using this technology can not only reduce labor costs, but also better solve the two major retail problems, namely, the outsourcing of goods and loss. The data shows that through the use of electronic labeling technology, Wal-Mart can save labor costs of US$8.35 billion each year, and can recover more than US$2 billion in losses due to theft. Because the electronic tag's dynamic information acquisition capability is very strong, the retailer can immediately feed back market information, so that manufacturers can quickly adjust the quantity and variety of products, thereby reducing the retailer's inventory and improving the utilization of funds.

Although electronic labels have bright prospects in some areas, they still have "benefits and difficulties in promotion" in other areas. For example, in the field of food safety, if a dish and a fish are also loaded with RFID, the cost is too high, and the foods for grain and oil are inconvenient to use. Consumers will not pay for this additional expenditure, so there is an obstacle to the promotion of end-use consumption. . If you want to promote RFID in areas of food safety and similar situations, the government should introduce appropriate policies to support and subsidize this, and advance the development of RFID technology to reduce costs to a level where the market can operate autonomously.
