How to Choose Ultra High Frequency Rfid Tag Label in the Project?

The market application scenarios of ultra high frequency RFID tag label are quite broad. It has the advantages of being able to read multiple tag labels at one time, long identification distance, fast data transmission speed, high reliability and longevity, and endurance to harsh outdoor environments. It can be used for asset management, production line management, supply chain management, warehousing, anti-counterfeiting traceability of various items (such as tobacco, alcohol, medicine), retail, vehicle management, etc.


The definition and coverage of ultra high frequency RFID tag label frequency bands around the world are not the same, for example: China's frequency band is 840 to 844MHz and 920 to 924MHz, EU frequency band is 865MHz to 868MHz, Japan's frequency band is 952MHz to 954MHz, and that of Thailand, Singapore is 920MHz to 925MHz, and the frequency band of the United States, Canada, Puerto Rico, Mexico, and South America is 902MHz to 928MHz.


1. Application environment of RFID tag label

Especially for ultra high frequency RFID product, metals and liquids have a greater impact on its performance. Therefore, the primary 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 label. When used in metal objects or a working environment with a lot of metal influence, metal-resistant RFID tag label must be used to reduce the influence of metal on the data signal of the tag label and facilitate the normal use of RFID tag labels.


The performance of ultra high frequency 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 test stage, it's performance must be tested with real objects, otherwise there is no reference value.


2. The influencing factors of the identification distance of RFID tag label

The reading distance is also directly related to the reader and antenna. It is necessary to clarify the installation position and angle of the tag label and the 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 finally meet the project requirements. Even the length of the feeder (the cable connecting the antenna and the reader) needs to be considered.


3. The size of the RFID tag label

Often customers hope that the size of the RFID tag label is as small as possible, so that it looks good and easy to install.


However, the size of the RFID tag label is precisely one of the main factors that determine the performance of the tag label. Generally speaking, the larger the size, the better the tag label performance that can be designed. Because different manufacturers have different models and specifications, and production technology and antenna manufacturing technology of integrated IC are different, there are certain differences in prices, so consumers should select products according to the actual usage and cost budget.
