Classification of RFID readers and their advantages [Copy link]

RFID readers are an indispensable part of the application system. The correct selection of RFID readers will affect the smooth implementation of customer projects and the cost of implementation. In terms of reader selection, it is best to go through a strict process to ensure the success of the project.

Classification

RFID readers can be divided into 125K, 13.56M, 900M, 2.4G and other frequency bands according to the frequency.

125K: Generally called LF, it is easy to use, low-priced, and can be mainly used in livestock entry and exit management in animal husbandry.

13.56M: Generally called HF, it has strong confidentiality and fast reading speed. The short-distance 13.56mhzRFID has good confidentiality, and the long-distance 13.56mhz reading is stable and fast. It is mainly used in home-school communication, personnel attendance management, entrance and exit management, anti-theft management of books and archives, and government meeting sign-in.

900M: Generally called UHF, with long communication distance and good anti-collision performance, it is generally used in parking lots and logistics.

2.4G: Microwave band RFID reader, strong penetration.

5.8G: Microwave band RFID reader, used in highway ETC electronic toll collection system.

Advantages

First, you need to pay attention to the frequency range of the reader device to see if it meets the frequency specifications of the project site;

Second, understand the maximum transmission power of the reader and whether the radiation of the matching antenna exceeds the standard;

Third, look at the number of antenna ports the reader has and whether the application requires a multi-interface reader;

Fourth, whether the communication interface meets the needs of the project;

Fifth, understand the reading distance and anti-collision indicators. The reading distance indicator should clearly state what antenna and tag are tested under; anti-collision should clearly state what tags are read in what arrangement and how long it takes to read all of them;

Sixth, in addition to the reader, an RFID application system is also related to the tag, antenna, material of the tagged object, movement speed of the tagged object, surrounding environment, etc. Before confirming the equipment, it is best to simulate the on-site situation for testing and verification to ensure that the product truly meets the application requirements;

Seventh, continuously test the stability of the equipment under simulation conditions to ensure long-term stable operation;

Eighth, check whether the development materials meet the system development requirements. It is best if they support the system you are using and have relevant routines. If they do not, the development time will be very long or even impossible to continue.
