  • What is RFID Technology?
    Sep 10, 2018
    RFID English full name Radio Frequency Identification, radio frequency identification, also known as electronic tags, radio frequency identification, inductive electronic chip, RFID proximity card, contactless card, electronic bar code. RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes the target object and acquires relevant data through the radio frequency signal. The identification work can work in various harsh environments without manual intervention. RFID technology recognizes high-speed moving objects and recognizes multiple labels at the same time, making operation quick and easy. Short-range RF products are not afraid of harsh environments such as oil stains and dust pollution. Bar codes can be replaced in such environments, such as tracking objects on the assembly line of a factory. Long-range RF products are mostly used for transportation, and the recognition distance can reach several tens of meters, such as automatic charging or identification of vehicle identity. The basic components of RFID The most basic RFID system consists of three parts: Tag: consists of a coupling element and a chip, each tag having a unique electronic code attached to the object to identify the target object; Reader: A device that reads (and sometimes writes) tag information and can be designed to be handheld or fixed; Antenna: Transmits RF signals between the tag and the reader. The electronic tag generally stores electronic data in an agreed format. In practical applications, the electronic tag is attached to the surface of the object to be identified. The reader can read and recognize the electronic data stored in the electronic tag without contact, thereby achieving the purpose of automatically identifying the body. Usually the reader is connected to the computer, and the read tag information is transmitted to the computer for further processing. The basic working principle of RFID technology The reader sends a certain frequency of the radio frequency signal through the antenna. When the tag enters the magnetic field, it generates an induced current to obtain energy. The information such as the self-encoding is read and decoded by the reader and sent to the host computer for processing. More rfid product info,please contact:sales@mhgyjs.com
