Quickly understand the types and classifications of RFID readers

RFID Reader (abbreviation of Radio Frequency Identification) is also called "RFID reader", which means wireless radio frequency identification. It automatically identifies the target object and obtains relevant data through radio frequency identification signals without manual intervention. It can identify high-speed moving objects and multiple RFID tags at the same time, and the operation is quick and convenient. RFID technology is currently used in many industries, such as logistics, anti-counterfeiting traceability, industrial manufacturing, ETC, etc. Especially after the concept of Industry 4.0 was proposed, RFID readers have been widely used in the manufacturing industry.

As an indispensable part of the application system, the correct selection of RFID readers will affect whether the customer project can be successfully implemented and the cost of implementation. In terms of reader selection, it is best to go through a rigorous process to ensure the success of the project. Explain the classification of RFID readers and their advantages.

Classification

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

125K: Generally called LF, it is simple to use and low in price. It can be mainly used for livestock entry and exit management in animal husbandry.

13.56M: Generally called HF, with strong confidentiality and fast reading speed. 13.56mhzRFID has good confidentiality at close range, and 13.56mhz has stable reading and fast speed at long distance. 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 segment RFID reader, with strong penetration.

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

Advantages

First, you need to pay attention to the frequency range of the RFID 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 selected antenna exceeds the standard;

Third, see the number of antenna ports the reader has, and whether a multi-interface reader is required according to the application;

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

Fifth, understand the reading distance and anti-collision indicators. The reading distance indicator must clearly specify what antenna and tag are tested; anti-collision must specify what tags are read in what arrangement and how long;

Sixth, in addition to RFID readers, an RFID application system is also related to tags, antennas, materials of labeled items, movement speed of labeled items, surrounding environment, etc. Before determining 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 to ensure that it can work stably for a long time;

Eighth, see if the development data meets the system development requirements. It is best to support the system you are using, and it is best to have related routines. If it does not support it, the development time will be very long, or even impossible to develop.

We are full of confidence in the future development. From the perspective of the industry, this is a new and promising intelligent high-tech industry that fundamentally solves the problems of enterprises or users, so the application field will become more mature and more extensive, and will gradually be pushed from the industrial field to the civilian field; from the perspective of the country, since the reform and opening up, Shenzhen has developed rapidly, and Shenzhen's rapid development is not only due to its superior geographical conditions, but also because it is a region centered on scientific and technological development; from the perspective of the company, our company has been adhering to the corporate culture of focus, innovation, and integrity since its inception, striving to take high, precise and cutting-edge as its development direction, focusing on the industry's leading technical research projects, and committed to providing global users with Internet of Things core equipment and RFID overall application solutions. Therefore, we will continue to improve existing products, develop new products, and constantly get involved in other different fields on the premise of improving existing application fields. And provide users with complete project solutions and perfect after-sales service and technical support.
