What are the main parts of the RFID system?

The basic components and some functions of the RFID system:

1, tag (Tag): It is composed of coupling components and chips. Each tag has a unique electronic code and is attached to the object to identify the target object; used for reader identification.

2, Reader (Reader): A device that reads (and sometimes writes) tag information, and can be designed as handheld or fixed.

3. Antenna (Antenna): transmits radio frequency signals between tags and readers.

The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal sent by the reader.

Use the energy obtained from the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag), or the tag actively sends a signal of a certain frequency (Active Tag, active tag) tag or active tag), the reader reads the information and decodes it, and then sends it to the central information system for relevant data processing.

RFID is the abbreviation of Radio Frequency Identification, which is a non-contact automatic identification technology that automatically identifies target objects through radio frequency signals and can quickly track items and exchange data. 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, making the operation quick and convenient. RFID technology was born during World War II and is the successor of traditional barcode technology, also known as "electronic tags".
