Self-adhesive electronic labels are used in anti-theft, anti-counterfeiting management, etc.
What is RFID technology, what are the basic working principles and components, what makes RFID so highly respected by retailers, and what are the typical applications of RFID, RFID China Forum provides information on the application solutions of RFID technology and the principle of electronic tags.
RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification. RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and identify multiple tags at the same time, which is fast and convenient to operate.
RFID basic components
The most basic RFID system consists of three parts:
Tag (Tag): composed of coupling elements and chips, each tag has a unique electronic code, which is attached to the object to identify the target object;
Reader (Reader): a device that reads (and sometimes writes) tag information, which can be designed as a handheld or fixed type;
Antenna: transmits radio frequency signals between the tag and the reader.
The basic working principle of RFID technology is not complicated: the basic principle is: the phenomenon of mutual inductance in electromagnetic induction. After the tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and transmits the product information (Passive Tag, passive tag or passive tag) stored in the chip with the energy obtained by the induced current, or actively sends a signal of a certain frequency ( Active Tag, active tag or active tag); after the reader reads and decodes the information, it is sent to the central information system for related data processing.
