Three parts of RFID system

　　Three parts of RFID system

　　The RFID system is mainly composed of three parts: tag, reader and antenna. Generally, the data information collected by the reader is sent to the background system for processing.

　　(1) Label: The label is composed of coupling components and chips. Each electronic label has a unique electronic code, which is attached to the object to identify the target object; each label has a globally unique ID number - UID (User Identity Certificate). ), which is stored in the ROM when making the tag chip and cannot be modified, which has a very important impact on the development of the Internet of Things.

　　(2) Reader: The reader is a device that reads or writes label information, and can be designed as a handheld or fixed type of work. Identify, read and write tags, and generally transmit the collected data information to the background system, and the background system processes the data information.

　　(3) Antenna: The antenna is used to transmit radio frequency signals between the tag and the reader. The antenna in the radio frequency circuit is the bridge connecting the reader and the electronic tag. The radio frequency signal energy sent by the reader is radiated to the space in the form of electromagnetic waves through the antenna. When the antenna of the electronic tag enters the space, it receives the electromagnetic wave energy, but only receive a small portion of it.

　　There are two antenna coupling methods between the reader and the electronic tag: one is the inductive coupling method, which is suitable for the low-frequency RFID system; the other is the backscattering coupling mode, which is suitable for the application of the RFID system in the ultra-high frequency band. . The antenna can be regarded as the air interface of the reader and the electronic tag, and is a very important part of the RFID system.
