RFID anti metal tag

RFID anti metal tag is a specially designed radio frequency identification tag that can reliably work in metal environments. Due to the reflection and absorption of radio waves by metals, the recognition distance and accuracy of ordinary RFID tags are often affected when operated on or near metal surfaces. Therefore, anti metal tags have emerged and are widely used in situations where asset management and tracking are required in metal environments. The following is detailed information about RFID anti metal tags, including their working principle, characteristics, application scenarios, and market prospects.

1. Working principle of RFID anti metal tag

Several key technologies are commonly used in the design of anti metal tags to overcome the interference of metals on radio signals. The basic working principle is as follows:

Isolation material: Anti metal tags typically use a special isolation material to prevent metal interference with RFID signals. This material can effectively isolate the RFID chip and antenna inside the tag from the metal surface.

Customized antenna: The anti metal tag antenna is specially designed to adapt to metal environments, in order to improve signal transmission and reception capabilities. This antenna design can better adapt to the influence of metal on signals.

Optimize frequency: Anti metal RFID tags are typically designed in the high frequency or ultra-high frequency (UHF) range to ensure good signal propagation in metal environments.

2. Characteristics of RFID anti metal tags

High temperature and corrosion resistance: Many anti metal tags can work in extreme environments such as high temperature, humidity, chemicals, etc., making them suitable for various industrial applications.

Long recognition distance: Compared to ordinary tags, anti metal tags can still maintain a relatively long recognition distance in metal environments, making asset tracking more convenient.

Strong recognition ability: Anti metal tags can effectively recognize metal surfaces or objects containing metal, maintaining a high recognition rate.

Multiple sizes and forms: Anti metal tags can usually be provided in various sizes and shapes according to specific application needs, for easy attachment to different objects.

3. Application scenarios of RFID anti metal tags

Industrial asset management: widely used for tracking and managing factory equipment, machinery, and tools, reducing asset loss and misplacement.

Logistics and Freight: Helps track the location and status of goods in metal transport containers, containers, and other situations.

Vehicle management: used for tracking and managing vehicles, suitable for applications such as car factories and parking lot management.

Medical equipment management: In hospitals, anti metal tags can help track expensive medical equipment and devices.

Power and energy management: In power facilities such as transformers, distribution boxes, etc., anti metal tags can be used to implement asset management and maintenance tracking.
