Introduction to the Working Principle and Performance of Micropower HF RFID Reader

With the continuous development and progress of the industrial Internet of Things, RFID wireless radio frequency identification technology has gradually become more and more widely used in various fields. For example, our common security access control, bus card swiping, etc. are all completed using HF RFID micro-power readers. This article will Let’s introduce the working principle and performance of micropower HF RFID reader.
 

Introduction to the working principle and performance of micropower HF RFID reader

The RFID reader mainly transmits signals through wireless radio frequency signals. The reader sends out a radio frequency signal of a certain frequency through the antenna. When the RFID tag enters the reader's workplace, the antenna generates an induced current, so that the RFID tag obtains energy and is Activate and send information such as its own code to the reader. The reader receives the carrier signal from the tag, demodulates and decodes the received signal and sends it to the computer host for processing. The computer system determines the legality of the tag based on logical operations. nature, make corresponding processing and control according to different settings, and send out command signals; the data demodulation part of the RFID tag demodulates the data from the received radio frequency pulses and sends it to the control logic, which receives the instructions to complete the storage, Send data or other operations.
 

The performance of micropower HF RFID reader is mainly reflected in the following aspects:

Identification distance: Micropower HF RFID readers can identify RFID tags within a certain distance, generally within a range of several meters to tens of meters.
 

Recognition speed: The micropower HF RFID reader can quickly identify high-speed moving objects and identify multiple RFID electronic tags at the same time, making the operation quick and convenient.
 

Durability: Micropower HF RFID readers have high durability and can work stably in different environments, such as high temperature, low temperature, humidity and other environments.
 

Security: Micropower RFID HF readers are generally equipped with a complete security mechanism to ensure data security and privacy.
 

Flexibility: Micropower RFID HF readers have high flexibility and can adapt to different application scenarios and needs, such as item tracking, access control systems, etc.
 

In short, micropower HF RFID readers have the advantages of high efficiency, flexibility, and security, and are widely used in various fields, such as logistics management, item tracking, access control systems, etc.
