RFID de dupla frequência é um mercado de aplicação relativamente especial. Ainda é relativamente estreito e a cadeia da indústria é relativamente simples. Além de tornar UHF+HF o mesmo IC , Ainda existem alguns cenários no mercado que utilizam o esquema de combinação de tags UHF + Tags HF com duas tags diferentes.
In addition to the chip threshold, dual-frequency tag equipment and manufacturing difficulties are also more difficult than ordinary tags, because the working principles of HF and UHF two different frequency bands are completely different, one is near-field coupling, and the other is far-field radiation, which requires two different antenna combinations.

além do que, além do mais, the current usage of dual-frequency products is not large, so dual-frequency RFID products, whether they are chips or tags, are more expensive than ordinary ones.
According to the information we have investigated, the application volume and application scenarios of dual-frequency RFID tags are increasing rapidly, and may become a new market growth point.
1. Introduction to the advantages of dual-frequency RFID
The advantages of dual-frequency RFID products mainly include the following two aspects
Vantagem 1: It retains the function of UHF RFID rapid inventory in large quantities
The biggest advantage of UHF RFID is that it has a long transmission distance and can be read in groups. It is very suitable for some scenarios that require quick inventory, especially in the B-side warehousing logistics and sorting links.
Vantagem 2: retains the ability of HF RFID to interact with mobile phones
Because NFC on mobile phones is a kind of HF RFID technology, HF RFID tags can interact directly with mobile phones, which greatly expands the use boundary of RFID. Anti-counterfeiting traceability requirements.
Assim sendo, dual-frequency RFID tag products can not only meet the needs of the B-side for efficient turnover, anti-lost, and visual management, but also meet the needs of the C-side crowd for anti-counterfeiting and traceability, which can form a good closed loop in business.
2. Dual-frequency RFID market and application introduction
The application scenarios of dual-frequency RFID products mainly have the following characteristics
Primeiro, the usage scenario needs to combine the high inventory efficiency of ultra-high frequency and the characteristics of high frequency interaction with mobile phones, which requires a relatively large amount of applications and concentrated, so that there is a demand for large-scale inventory; e o leitor RFID obtém as informações do item sem contato, product consumption It has strong attributes and needs to interact directly with consumers.
Segundo, the unit price of the product in the application scenario is more expensive. Because the product is more expensive, it will stimulate consumers’ demand for anti-counterfeiting traceability. além do que, além do mais, the price of the dual-frequency RFID tag product itself is also much more expensive than the single-frequency tag. Only high-value scenarios can afford such a cost input.
Terceiro, there is a strong demand for authenticity identification, but there is a lack of authoritative endorsement products in the market. This kind of product requires consumers to identify the authenticity by themselves, which requires the use of technical means.
According to this logic, we think the following areas are more suitable for dual-band products.
1. High-end alcohol products
This field is a scene where dual-frequency RFID products are being used in large quantities, because high-end liquors have a large shipment volume, such as Maotai, Wuliangye and other high-end liquors, which are in the tens of millions or even hundreds of millions of shipments per year. There is a demand for warehouse inventory. além do que, além do mais, the price of high-end liquor can range from several hundred yuan to several thousand yuan, which can fully cover the input cost of dual-frequency labels. Consumers have relatively high requirements for the authenticity of liquor.
2. Luxury
Por exemplo, high-end watches, bags and other products are very expensive. Consumers have a rigid need for the authenticity of such products. além disso, the scale of the current market is also relatively large and requires a faster inventory. Assim sendo, dual-frequency is in this category. There are also more scenarios. It is understood that there are also many luxury brands in foreign markets that are trying to use dual-frequency RFID tags.
3. Collectibles
Collectible products include gold, stone, jade, antiques, calligraphy and paintings, and various handicrafts. These products are very expensive, but they require a high degree of professional ability to distinguish between true and false. It is difficult for ordinary people to identify them, so they need to use dual-frequency RFID tags. screening.
4. Biblioteca
Atualmente, some libraries in China use dual-frequency solutions, but this is a problem left over from the development of the industry, because in the early days, many libraries used high-frequency tags, but with the maturity of UHF RFID and cost reduction, UHF RFID It can also meet the market demand, resulting in many libraries that use high-frequency solutions need to use dual-frequency solutions to overdo it.
