Dual-frequency RFID is a relatively special application market. It is still relatively narrow and the industry chain is relatively simple. At present, the dual-frequency RFID chips on the market mainly use UHF+HF to make the same IC. There are still some scenarios in the market that use UHF. Tag + HF tag two different tags combined scheme.
In addition to the chip threshold, dual-frequency tag equipment and manufacturing 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.
In addition, the current usage of dual-frequency products is not large, so dual-frequency RFID products are more expensive than ordinary ones, whether they are chips or tags.

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

1. Introduction to the advantages of dual-frequency RFID

The advantages of dual-frequency RFID products are mainly in the following two aspects:

>>Advantage 1: The function of UHF RFID for rapid inventory in large quantities is retained

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.

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

Because the NFC on the mobile phone is a kind of HF RFID technology, the HF RFID tag can interact directly with the mobile phone, which greatly expands the use boundary of RFID. Anti-counterfeiting traceability requirements.
Therefore, 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:

1. The usage scenarios need 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, and then there is a demand for large-scale inventory; in addition, the consumption attributes of products are strong , need to interact directly with consumers.
2. The unit price of the product in the application scenario is more expensive, because the product is more expensive, it will stimulate the consumer's need for anti-counterfeiting traceability. Only high-value scenarios can afford such a cost input.
3. 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:

• High-end alcohol products

This field is a scene where dual-frequency RFID products are being used in large quantities, because high-end liquors are shipped in large quantities. There is a demand for warehouse inventory. In addition, the price of high-end liquor can range from a few hundred yuan to thousands of yuan, which can fully cover the input cost of dual-frequency labels. Consumers have relatively high requirements for the authenticity of liquor.

• Luxury

For example, high-end watches, bags and other products are very expensive. Consumers have a rigid need for the authenticity of such products. Moreover, the scale of the current market is also relatively large and requires a faster inventory. Therefore, 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.

• Collection

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.

• Library

At present, some libraries 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 and cost reduction of UHF RFID, UHF can also To meet market demand, many libraries that use high-frequency solutions need to use dual-frequency solutions to overdo it.
