RFID Anti-counterfeiting Solution

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

Application Scheme of RFID Anti-counterfeiting

RFID technology can effectively solve the increasingly rampant phenomenon of product counterfeiting and forgery prevention
It is estimated that the world’s market affected by counterfeit products reaches 300 billion US dollars annually, which is quite alarming, 10% of the total world trade. While counterfeit products are flooding the market, they also cause a lot of work to be lost. The EU estimates that 100,000 people have lost their jobs because of counterfeit products. Needless to say, some inferior products of special products, such as aircraft parts and medicines, directly threaten people’s life safety.

For manufacturers, one of the main advantages of RFID technology is that it can be directly integrated into existing products, machines or equipment without major changes to existing production equipment. The RFID tag itself has the function of reading and writing, which can be written into the manufacturer’s unique encrypted codes and easily integrated into various commodities.
An important factor of whether the RFID system can be used in commerce is that the same kind of tags can be applied to different products because this can lead to the expansion of the scale of tag production, and ultimately reduce the price of tags to an acceptable range. However, for some valuable commodities, the size of the label is far more important than the price of the label.
In general, UHF tags are larger in size than UF tags. For small and valuable goods, a slightly larger size of the label may affect the appearance of the goods. In such cases, the size of the label required is as small as possible, which will not hinder users. From the point of view of tag storage data, read-only tags are generally one-time programmable, low-cost, but there must be a backup database to track effectively.
Label data that can be read and written many times is stored in a large amount. Generally, all product information can be stored without the support of the backup database. This kind of label is more expensive and larger than the one-time programmable label.
For manufacturers, the last thing they want to see is that the reading of RFID data slows down production. UHF tags have a long reading distance, generally suitable for use in containers or pallets; HF reading distance is relatively short, suitable for some fixed places such as shelves.
When using RFID tags, another factor to be carefully considered is the material of the goods. This has a particular impact on products that are in constant contact with water or where the label is attached to metal. In the former case, the label must be waterproof and use HF technology; because the longer wavelength of HF system is not easy to be absorbed, the high-frequency RF signal is easier to penetrate water or other liquids. HF labels have been tested on textiles and clothing for many years and have proved to be resistant to large changes in liquid, pressure and temperature range.
When the tag is attached to the metal surface, it will also affect the RFID system. RF signal can not pass through metal, so when the metal material is close to HF antenna or UHF tag and reader, the reading and writing distance of the RFID system will be greatly affected. Another disadvantage is absorption: metals can absorb RF signals, which also affects HF and UHF tags in varying degrees.
The reading and writing distance of HF tag is relatively short. UHF tags are far enough from the metal surface to read and write, 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 5 mm.

In the application of RFID anti-counterfeiting, clothing anti-counterfeiting is commonly used.

Clothing manufacturers put their own unique RFID reading and writing labels in cartons with the clothes they produce. Each carton has its own unique ID code. When the production process is completed to the delivery process, each carton passes through an RFID tag reader, and all the information of the carton is read and transmitted to the PC. Comparing the actual information read by PC software system with the planned deliveries of the carton, we can judge whether the carton is released or not. At the same time, if the carton is released, the ID number of the carton will be written into the memory of each label and locked.
Manufacturers can also write corresponding information to other data blocks of tags through handheld RFID devices in QA inspection and other stages. In this way, the entire transport of all clothes from production to distribution centers to retail sales can be recorded.

RFID Technology Helps to avoid Wine Products

Robert Louis Stevenson, a famous American writer, once compared wine to “bottled verse”. Today, as wine producers and sellers gradually turn their attention to radio frequency identification technology (RFID), this magical liquid seems to add a bit of “wisdom” besides romance. ” In addition, wine manufacturers are constantly looking for new ways to promote their products. In the colorful packaging marketing, RFID will gradually become a new favorite. While realizing the tracking function, it will also help to improve the product safety of the consumer supply chain, and for the long-term problem of product forgery entangled in the wine industry, RFID is also a big problem. It’s good.
Recently, Americans’enthusiasm for wine has increased considerably. The number of people who drink at least one glass of wine a week has increased from 19.2 million in 2000 to 2.
