Solutions of RFID technology in different fields and industries
Thailand's aquaculture uses RFID to track seafood
in order to distinguish a large number of shrimp products from different farms, ie technology company, a Thai RFID application provider, has been studying how to implant RFID chips into fish before distributing shrimp to various processing sites, otherwise the freezing and tightening opportunities will be damaged In the plastic boxes used in farms and intermediate markets to hold shrimp, so as to understand the "context" of shrimp
this study aims to support the second phase of the food tracking program jointly carried out by the Ministry of industry and the Ministry of science and technology in Thailand, where only skilled farmers can ensure the stability of machine production. This plan enables producers, kitchen staff and even ordinary consumers to understand the source and processing of food to ensure food safety
naiyavud wongkomet, general manager of IE, said: "Shrimp is usually transported from the fishery to the market in boxes, then mixed according to the size, and finally loaded into large containers. In the process of transportation, people load shrimp from one box to another, and then to other places. Although the farm has installed an automatic system to store shrimp data, these data will inevitably be confused in the processing process, so it is impossible to determine which fishery shrimp is loaded in the box."
in order to solve this problem, the company has studied embedding RFID chips in plastic boxes. This chip is implanted into each box used in fishing grounds, intermediate markets and processing plants to store all data related to shrimp, including origin, species, disease records and the use of electronic universal experimental machinery produced by mainstream domestic experimental machine manufacturers
naiyavud wongkomet said: "bar codes are afraid of water and can only be used within a certain temperature range. There are no such concerns when using RFID chips. More importantly, the speed at which RFID chips read and transmit data is unmatched by bar codes."
apiwat thongprasert, consultant of IE technologies' business development department, said: "It is not easy to implant the RFID chip into the plastic box, because before sealing the box with resin, the chip must be placed in one of the many holes. The sealed box needs to use an appropriate amount of resin, and the data transmission must be able to penetrate the seal. In order to make the box implanted with RFID widely used, we are considering implanting the chip in the box molding process, but this requires more extensive cooperation."Apiwat said that the chip used in the food tracking program was developed by silicon process technology, which was the first company in Thailand to design RFID chips. The chip is 134.2 kHz, passive and low-frequency. Its advantages are that it is not afraid of water and low temperature, and allows wireless data reading. IE technology company has also developed an RFID reader that is not afraid of ice and water. In order to adapt to the daily work of the shrimp market, the company has designed two types of fixed and portable from the beginning. The fixed reader can read the data in the chip implanted in the box, and the portable reader can double check the data in the chip to prevent any possible errors. Once the shrimp in the box is confused, the reader can scan the box by box until the last box is scanned before copying the information. He said: "the decipherer cannot accurately show which fishery the shrimp in the box belongs to, but through the data cloned from one box to another, the manufacturer can accurately know how many fisheries the shrimp in each box comes from. This helps to shorten the tracking process."
since shrimp importers and exporters have to submit ds-2031 declaration form to the Ministry of fisheries to obtain the license for this business, the relevant authorities plan to allow these importers and exporters to submit forms and receive licenses. The identification number assigned by the Fishery Bureau to the company will be stored in the RFID chip embedded in the box. In this way, when tracing back, we can find out the source of the shrimp in the box. In order to complete the box tracking process, FXa group is developing software that can manage the RFID information flow. FXa, a food industry software company, has developed a network-based data tracking software, which enables agricultural exporters to collect and track all information related to their product processing through electronic technology
rfid will become a sword to ensure food safety
many developed countries attach great importance to food safety. In addition to establishing relevant legal systems, they also use high-tech means to manage food safety. For example, Japan has established a "food ID card system", that is, a product resume and tracking and monitoring system, which requires the production, circulation and other departments to widely adopt electronic labels such as bar code technology and radio frequency identification technology to record various data in the production and circulation process of products in detail
in foreign countries, many feedlots have used RFID tags to monitor the basic conditions of livestock and animals in the whole process (such as growth, health, circulation process, etc.), so as to form a complete industrial chain food safety control system. Its principle is to apply rfid+ bar code technology throughout the whole process of food safety (breeding pigs → feeding → slaughtering → segmentation → small packaging → transportation → dining table), and strictly control the whole process of the industrial chain, Ensure to provide the market with high-quality assured meat food. Once the sold pork has quality problems, the information can be tracked and supervised according to the labels of pork packaging. The plane of concrete foundation is leveled by horizontal leveling
the first application of RFID technology in the fresh food industry has also appeared in Australia. Moraitis is partnering with IBM to use RFID tracking systems. The RFID system will provide detailed information about the origin, packaging date, variety, quality and size of tomatoes shipped from Moraitis every day
Sysco, the largest food service marketing and distribution organization in North America, has completed the radio frequency (RFID) and sensing system tests of the cryogenic storage and transportation system. This test proved the ability of RFID to monitor temperature and environmental conditions during food transportation, and made a big step forward in ensuring food quality and safety
in the UK, trenstar and Scottish courage brewing showed how to use RFID tags to better track wine cans. Wine manufacturers can also use RFID tags of sensing technology to monitor the temperature changes in the environment of wine barrels that can affect the quality of wine products
in terms of anti-counterfeiting, wine can not be unpacked on the spot to check its authenticity, which provides an opportunity for counterfeiters. In order to prevent the impact of counterfeits, Sassicaia's manufacturers are further considering adding RFID chips to the labels of wine bottles
in China, RFID technology is also applied to food safety tracking management. For example, Zhejiang Provincial Fisheries Bureau, Hangzhou Municipal Bureau of technical supervision and the organic food development center of the State Environmental Protection Administration also jointly launched the "Chun" Organic Fish ID card, an intelligent anti-counterfeiting card for fish products, in the domestic aquaculture industry for the first time this year, realizing the whole process quality tracking management from the water body to the dining table
