Why the animal industry will be the way out for low-frequency RFID

What is low frequency RFID

The operating frequency of low-frequency RFID is relatively low, and the typical operating frequency is 125KHz. 134KHz, the frequency is mainly through inductive coupling, and the working principle is the same as that of HFRFID.

The commercial time of low-frequency RFID is early, and the technical threshold is relatively low. In terms of volume, the proportion of low-frequency RFID is small, but its unique technical features still have irreplaceable advantages in some application fields.

The main technical characteristics of low frequency RFID are as follows:

Anti-interference ability is also strong, especially anti-liquid. Anti metal. The blocking performance is good, but again, its transmission speed is relatively low. Disadvantages such as short working distance.

One-to-one transmission has high recognition accuracy, but it also has the disadvantage of not being able to read in groups.

Although there are not many players in the entire low-frequency RFID market, there are still a number of companies cultivating this market.

Analysis of LF RFID Application Field

According to our research information, the main application market of LF RFID is animal tags (including pets). livestock. poultry, etc.). Access Control. Car keys and anti-theft systems, etc.

In addition to the above-mentioned main application areas, low-frequency RFID has other applications, mainly including medical treatment. Buried label. industry etc.

The medical field is mainly medical cards. Although the market has shrunk severely in recent years, there are still millions of stable shipments every year.

Buried tags have been another bright spot in the market over the past few years. It solves the market demand for buried cables in underground power pipelines, facilitates subsequent construction, accurately finds the location of cables, and avoids construction failures.

The market is mainly the demand of the State Grid. Although the annual shipment of buried tags is small, only about 1 million, these tags require a high level of protection and excellent RF performance. Therefore, the price of a single label is higher.

Industrial applications are also a relatively concentrated field of low-frequency RFID applications. The typical scenario is AGV vehicles. In addition, another typical application scenario for industrial applications is station labeling in factories, as well as factory inspection and identity authentication. Some factory environments are also faced with metals due to the need for stable and reliable products in factory environments. Therefore, there is also a certain market for RFID in interference environments such as low-frequency blocking.

In addition, wafer production plants in the semiconductor industry are also one of the applicable scenarios for low-frequency RFID due to the high electromagnetic requirements of the wafer production environment. RFID electromagnetic interference is small and applicable.
