The advantages and application value of dual frequency RFID

Dual frequency RFID is a relatively special application market, and the industry chain is also relatively simple. In addition to making UHF+HF into the same IC, there are also some scenarios in the market that use the combination of UHF tags and HF tags as two different tags.

In addition to the chip threshold, the design and manufacturing difficulty of dual frequency tags is also greater than that of ordinary tags, because the working principles of HF and UHF in different frequency bands are completely different, one is near-field coupling and the other is far-field radiation, requiring two different antenna combinations. In addition, dual band RFID products are currently not widely used, so both chips and labels are relatively expensive.

According to the information we have researched, the application volume and scenarios of dual frequency RFID tags are rapidly increasing, which may become a new market growth point.

Introduction to the advantages of dual frequency RFID

The advantages of dual frequency RFID products are reflected in the following two aspects

Advantage 1: Retaining the function of UHF RFID for large-scale and rapid inventory

The biggest advantage of UHF RFID is its long transmission distance and the ability to read in groups. It is very suitable for scenarios that require fast inventory, especially in the B-end warehousing logistics and sorting processes.

Advantage 2: Retaining the ability of HF RFID to interact with mobile phones

Because NFC on mobile phones is a type of HF RFID technology, HF RFID tags can have direct interaction with mobile phones, greatly expanding the boundaries of RFID usage. In daily consumer goods, there is a need to distinguish authenticity and anti-counterfeiting traceability for more valuable items.

So, dual frequency RFID tag products can meet the needs of asset management and efficiency turnover on the B-end, as well as the needs of anti-counterfeiting and traceability on the C-end, and can form a good closed loop in business.

Introduction to the Dual Frequency RFID Market and Applications

The application scenarios of using dual frequency RFID products mainly have the following characteristics

Firstly, the usage scenario needs to combine the high efficiency of ultra-high frequency and the characteristics of high-frequency interaction with mobile phones, which requires a large and concentrated application volume to meet the demand for large-scale inventory; And the product has strong consumer attributes, requiring direct interaction with consumers.

Secondly, the unit price of products in application scenarios is relatively expensive, as it stimulates consumers to demand anti-counterfeiting and traceability. In addition, the price of dual band RFID tag products is much higher than that of single band tags, and high-value scenarios are needed to bear such cost inputs.

Thirdly, there is a strong demand for authenticity identification, but there is a lack of authority to endorse products in the market. These types of products require consumers to identify the authenticity themselves, which requires the use of technological means.

According to this logic, we believe that the following areas are more suitable for adopting dual band products.

1. High end alcoholic products

This field is a scene where dual band RFID products are being used in large quantities. On the one hand, high-end liquor has a large shipment volume, such as Maotai, Wuliangye and other high-end Baijiu. The annual shipment volume is tens of millions or even hundreds of millions of levels. There is a demand for warehouse inventory. In addition, high-end Baijiu can be sold for hundreds of yuan at least and thousands of yuan at most, which can completely cover the input cost of dual band labels, Consumers have a high demand for the authenticity of Baijiu.

2 Luxury goods

For example, high-end watches, luggage and other products are very expensive, and consumers have a strong demand for the authenticity of these products. Moreover, the market size is also large, requiring a quick inventory, so dual frequency is also commonly used in such scenarios. It is understood that many luxury brands in foreign markets are also trying to use dual band RFID tags.

3 Collectibles

Collectibles include gold, stone, jade, antique calligraphy and painting, as well as various handicrafts. These products are very expensive, but identifying authenticity requires high professional skills. The difficulty of ordinary people identifying them is relatively high, so dual frequency RFID tags need to be used for technical identification.

4 Library

At present, some libraries in China adopt dual frequency solutions, but this is a legacy issue of industrial development. In the early days, many libraries used high-frequency tags. However, with the maturity and cost reduction of UHF RFID, UHF can also meet market demand, leading to many libraries that use high-frequency solutions needing to adopt dual frequency solutions to transition.
