RFID technology canti-counterfeiting products.

RFID technology can effectively solve the rampant anti-counterfeiting phenomenon of products. In RFID anti-counterfeiting applications, clothing anti-counterfeiting is commonly used. Clothing manufacturers put their own unique RFID tags and clothing in cartons at the same time, and each carton has its own unique ID code.

  RFID technology can effectively solve the increasingly rampant anti-counterfeiting phenomenon

   It is estimated that the world’s market affected by counterfeit products reaches 300 billion US dollars per year. This number is quite alarming, accounting for 10% of the world’s total trade. While counterfeit products are flooding the market, they also cause a lot of job losses. The EU estimates that 100,000 people lose their jobs due to counterfeit products. Not to mention, the inferior products of some special products, such as aircraft parts and medicines, directly threaten people's lives.

  The world's market affected by counterfeit products reaches 300 billion US dollars every year, which is 10% of the world's total trade.

  For manufacturers, one of the main advantages of RFID technology is that it can be directly integrated into current products, machines or equipment without major changes to current production equipment. The RFID tag itself has the function of reading and writing, and can be written into the manufacturer's unique encrypted code, and is easily integrated into various products.

   An important factor for whether the RFID system can be used in business is that the same type of label can be applied to different products, because this can lead to the expansion of the label's production scale, and ultimately reduce the price of the label to an acceptable range. However, for some valuable goods, the size of the label is far more important than the price of the label.

  In general, the size of UHF tags is larger than that of UF tags. For small and expensive products, a slightly larger label is likely to affect the appearance of the product. In this case, the size of the label required is as small as possible, which will not hinder the user. From the perspective of tag storage data, read-only tags are generally one-time programmable and low-cost, but must have a backup database for effective tracking.

   The storage capacity of the tag data that can be read and written many times is relatively large, and can generally store all product information without the support of a backup database. Such tags are relatively expensive, and the size is larger than one-time programmable tags.

  For manufacturers, the last thing they want to see is that the reading of RFID data delays the speed of production. UHF tags have a longer reading distance, and are generally more suitable for use on cargo boxes or pallets; HF reading distance is shorter, suitable for some fixed places such as shelves.

  When using RFID tags, another factor to be seriously considered is the material of the goods. This has a particular effect on products that frequently come into contact with water during use, or where the label is attached to metal. If it is the former case, the tag must be waterproof and use HF technology; because the longer wavelength of the HF system is not easy to be sucked, the high-frequency RF signal is more likely to penetrate water or other liquids. HF tags have been tested on textiles and apparel for many years and have been proven to resist large changes in liquid, pressure and temperature range.

  When the label is attached to the metal surface, it will also affect the RFID system. The RF signal cannot pass through the metal, so when the metal substance is relatively close to the HF antenna or UHF tag and reader, the reading and writing distance of the RFID system will be greatly affected. Another adverse effect is absorption: metals can absorb RF signals, which also affects HF and UHF tags to varying degrees.

   The reading distance of HF tags is relatively short. When the UHF tag is far enough from the metal surface, the reading and writing distance is relatively long; but if the tag is too far from the metal surface, its abrupt part will affect the usability of the tag, so the ideal height is 5mm.

  In RFID anti-counterfeiting applications, clothing anti-counterfeiting is commonly used

  Apparel manufacturers put their own unique RFID read-write tags together with the produced apparel in cartons. Each carton has its own unique ID code. When the production is completed to the shipping process, each carton passes through an RFID tag reader, and all the carton information will be read and transmitted to the PC. The PC software system compares the actual information read with the planned delivery items of the carton to determine whether it will be released. At the same time, if the carton is released, the carton ID number will be written into the memory of each label and locked .

  The manufacturer can also write the corresponding information to other data blocks of the tag through the handheld RFID device during the QA inspection and other stages. In this way, the entire transportation process of all clothing from production to distribution center to retail can be recorded.

  RFID technology can help counterfeit wine industry products

The famous American writer Robert Louis Stevenson (Robert Louis Stevenson) once compared wine as a "bottled verse". Today, as wine producers and sellers gradually turn their attention to radio frequency identification technology (RFID), this In addition to romance, this kind of magical liquid seems to add a little "wisdom". In addition, wine makers are constantly looking for new ways to promote their products. In the colorful packaging marketing, RFID will gradually become the new favorite. While achieving the tracking function, it will also help to improve the product safety of the consumer supply chain. RFID is also of great benefit to the problem of counterfeiting products in the wine industry.

   Recently, Americans' passion for wine has increased a lot, and the number of people who drink at least one glass of wine per week has increased from 19.2 million in 2000 to 25.4 million in 2003. According to "Entrepreneur" magazine, this growth trend will continue. In addition to the richer and older Baby Boomers, young people in the millennium, who are in their 20s, have also shown great interest. As a result, the wine industry in the United States has experienced rapid growth, wine sales have been rising, retail sales have increased by 2.8 percentage points, and restaurant and bar sales have increased by 8.1 percentage points. This year the wine market is expected to reach 21.6 billion US dollars. The latest data from the American California Wine and Alcohol Association shows that California wine production will still dominate the US market. There are more than 3,000 wineries across the United States, and more than 800 in California alone.

   RFID requirements for wine manufacturers and retailers

Although the wines in supermarkets and specialty stores come from many different factories, the trend in the US market in recent years has become more and more centralized, because the cost of land and operations has skyrocketed, competition has become more intense, and wineries are constantly merging to form economies of scale. Other wineries have been acquired by other major brands, such as Constellation Brands, Diageo and Chalone Wine Group. EJ Gallo is a leading American wine producer and the second largest wine group in the world. With its huge sales volume, Gallo was also included in Wal-Mart's list of the second batch of leading suppliers who must complete the ban. Before January 2006, RFID tags were attached to pallets and boxes shipped to Wal-Mart.

  According to the report of the AMR survey company, the consumer goods company spent about 25 million US dollars to complete the Wal-Mart request. But the difficulties and complexity of wine manufacturers are greater than any other consumer goods company. This is because US wine sellers must use local distributors in order to comply with national laws. To meet Wal-Mart’s requirements, wine makers cannot simply develop and use their own internal RFID systems. They must work with distribution partners to fulfill the requirements. In practice, company wines like Gallo have to rely on supply chain partners to ensure that manufacturers meet the requirements. On the other hand, if distributors use RFID tags, they can bring value-added services to major producers at least in the short term.

  As the scope of retailer requirements expands, more wine companies need to use at least RFID tags on pallets and boxes. For the wine industry, it is necessary to consider from different perspectives not only to complete the requirements but also to assess the potential benefits of RFID for the enterprise, and improve the tracking and monitoring of the production process and finished products. The brewery not only wants to improve internal management operations by using RFID tags on the pallets and boxes of finished products, but also wants to use RFID tags on wooden barrels in the production process. In the United Kingdom, Trenstar and ScotTIsh Courage Brewing showed how to use RFID tags to better track casks. Their application shows that by using special materials to make tag antennas and choosing appropriate locations to install RFID facilities on containers, the reading rate of liquid targets can be greatly improved. Wine manufacturers can also use sensor technology RFID tags to monitor changes in the ambient temperature of wine barrels that can affect wine quality.

   It seems that the application of labels for wine products and aquatic products is stronger than any other food and beverage market. Harvard Business School Jonathan Byrnes believes that the cost-benefit ratio of using RFID on low-value department store goods is too high. However, for alcoholic beverages, the return on investment of using RFID is much higher, because the price of the label is much higher than that of other department stores.

   The market structure of the American wine industry also shows the importance of using RFID tags on wine bottles. If $7 per bottle is used as the tipping point for high- and low-price wines, then the sales of low-priced wines account for 70%, while 62% of the profits of wine manufacturers come from the sale of high-priced wines. Therefore, wine manufacturers want to promote the use of labels in high-priced products from the three aspects of higher safety, better control and market value.
