Environmental issues of label application
Especially for UHF RFID products, metal and liquid have a greater impact on its performance. Therefore, the first consideration is whether the application environment is metal or non-metal, liquid or plastic, glass, wood, etc. The direct influence of raw materials on the radio frequency signal: Metal has an influence on the radio frequency signal of the RFID tag. When used in a working environment where metal objects or metals have a great influence, metal-resistant electronic tags must be used to reduce the impact of metal on the data signal of the tag. , In order to facilitate the normal use of RFID electronic tags.
The performance of UHF RFID tags is easily affected by the environment. If it is necessary to determine whether the product is suitable for the actual application environment, in the early stage of the test, the performance must be directly used for the object test to have reference value.
2. Factors affecting tag recognition distance
The reading distance is also directly related to the reader and antenna. It is necessary to figure out the installation position and angle of the tag and reader antenna. At the same time, parameters such as power selection, antenna gain, polarization mode and radiation angle are all categories that need to be considered.
In the entire RFID system, every detail may affect the actual reading distance and whether it can ultimately meet the project requirements. Even the length of the feeder line (the cable connecting the antenna and the reader) needs to be considered.
Three, understand the size of the label
According to our past experience in many projects, customers often hope that the label size is small, so that it looks beautiful and easy to install.
However, the size of the label is precisely one of the main factors that determine the performance of the label. Generally speaking, the larger the size, the better the design performance of the label. Different manufacturers, models and specifications, integrated IC production technology and antenna manufacturing technology, there are certain differences in price, consumers should choose according to actual usage and cost budget.
Four, other matters needing attention
In addition, there are other detailed considerations, such as: Does the label have environmental reliability requirements, such as high temperature and humidity resistance? How much data capacity does the label need to write? What is the maximum number of tags that need to be read at one time? and many more...
