How to select UHF RFID tags for application projects?


Latest company news about How to select UHF RFID tags for application projects?

Uhf RFID technology has been widely used in various industries with the characteristics of remote reading and multi-label reading, and the correct selection of UHF rfid tags plays a very important role in the good operation of the entire RFID system. This paper will take UHF RFID tags as an example to describe the selection of RFID tags, hoping to be helpful to everyone.

In the face of a variety of projects with different application needs, there are a wide variety of RFID tags, and the performance, characteristics, advantages and disadvantages of each tag are different.

For example, UHF RFID universal tags such as wet/dry inlay, etc.; UHF RFID opposite-sex labels, metal resistant labels of various sizes and materials, high temperature resistant labels; UHF RFID flexible tags and so on.

Some models of RFID tags are specially developed for certain application ways and scenarios, and have special designs in label size, material and performance.

Some models of RFID tags are universal in design and application and can be applied to a variety of scenarios. Special and general products, in the performance of different scenes, there will be a certain difference and gap.

How to choose the RFID tag that is suitable for your project application, so as to achieve the good operation of the entire RFID system and avoid the tag link becoming the short board of the RFID system? !

First, it is necessary to clarify the environment of label application
In particular, UHF RFID products, metals and liquids have a greater impact on their performance. Therefore, whether the application environment is metal or non-metal, liquid or plastic, glass, wood, etc., is the primary consideration.
This will directly determine the category of UHF RFID tag selection. Conventional labels can not be directly used on the metal surface, only specially designed anti-metal labels can have good performance on the metal surface, and such labels are generally the larger the metal surface is pasted, the better the performance.
Uhf RFID tag performance is vulnerable to environmental impact, if you need to determine whether the product is suitable for the actual application environment, in the early test stage, must be directly used on the object test performance to have reference value.


Second, it is necessary to delimit the expected value of the label recognition distance
The reading distance is also directly related to the reader and antenna, and it is necessary to clarify the installation position and Angle relationship between the label and the reader antenna. At the same time, power selection, antenna gain, polarization mode, radiation Angle and other parameters should be considered.
In the entire RFID system, every detail may affect the actual reading distance, and whether the project requirements can be ultimately met, even the length of the feeder (the cable connecting the antenna and the reader) needs to be considered in place.


Third, the size of the label needs to have a clear understanding and reasonable understanding
In our past experience with many projects, often customers want the label size to be small, so that it is both good-looking and easy to install.
However, the size of the label is precisely one of the main factors determining the performance of the label. In general, the larger the size, the better the label performance can be designed, and the size is also related to the medium environment where the label is located, the label substrate, and so on. At the same time, the packaging form of the label is directly related to the cost of the label, which are factors that must be considered comprehensively when doing customer operation projects.


In addition, there are other details to consider such as:
Does the label meet environmental reliability requirements such as temperature and humidity resistance?
How much data does the label need to write?
What is the maximum number of labels to be read at a time?

And so on...

Of course, in the actual label selection work, matters that need to be considered are far more than the above points.
Based on our extensive project experience over the past few years, it takes constant communication of requirements and a lot of testing to verify that the selection is suitable.
