Analysis of common problems in selecting RFID anti metal tags for RFID electronic tags 123
Selecting suitable metal resistant labels with good reading and writing performance can easily solve the problem of more stable metal and environmental performance. So how to choose the right RFID anti metal tag? Donglai Electronics’ editor summarizes the following five points:
1. What kind of metal labels will be recommended?
Many factors need to be considered in the selection of labels in a specific application, such as the price of labels, the physical size and shape of labels; However, more attention should be paid to the reading and writing distance and the material of the label, the material of the mounting surface, the mounting method and the impact of the surrounding environment (including metal, humidity, current and other factors), which are related to the durability and reading and writing performance of the label. In order to achieve high-quality and reliable label reading and writing effect, it is necessary to analyze multiple variables in the environment.
2. Why is the reading and writing distance of the tag different from the experimental data?
The label will be designed and adjusted according to the application environment, such as adding protective coating or manufacturing gap to prevent the label from being directly installed on the metal. These practices may reduce the label performance, so that the actual performance is less different from the original design performance.
In most cases, the tag will lose a certain reading and writing distance due to the impact of the application environment, especially when the tag is embedded in metal or installed in a multi-metal environment. Ordinary labels will maintain a certain performance temporarily, but to achieve sustained and stable label performance, you must choose a label that is consistent with the application environment.
3. How to label assets?
After ensuring the reading and writing performance of tags in harsh environments, the problem of installing tags comes one after another, which is also one of the biggest challenges in RFID applications. High performance metal labels can resist high temperature or immersion in liquid, but the adhesive backing of the label may not be able to withstand it. The most ideal application is to embed tags in assets to ensure that tags are not affected by the external environment to the greatest extent. However, in practical applications, the embedded method does not necessarily meet the actual needs.

Adhesive backing is one of the most commonly used methods for installing labels. When selecting adhesive backing, it is necessary to conduct a comprehensive and detailed analysis of the application environment. Extreme cold environment will also affect the performance of the adhesive backing and lead to the embrittlement and fragility of the label. Therefore, it is necessary to fully consider the temperature of the storage environment and workflow of the label. Not all applications can use adhesive backing to install labels. Other common installation methods include bolt fixation, tape hanging or epoxy adhesive fixation.
4. What are the potential interference sources in the application environment?
The fact that the label is not directly attached to the metal does not mean that it will not be disturbed by the metal. If the asset where the label is installed is rich in metal, or the asset will pass through the environment of multi-metal storage in the process of moving, the use of the label must be carefully judged to ensure stable and reliable performance.
5. Can the high temperature label be used in all high temperature applications?
Not necessarily. Many different applications will require labels to resist high temperature. For example, a label designed for use in a dry and hot environment cannot be used in a high-temperature and high-pressure steam sterilization environment, and may not meet other types of high-temperature applications.
