Electronic tags are also known as radio frequency tags, transponders, and data carriers; readers are also known as readout devices, scanners, read heads, communicators, and readers (depending on whether the electronic tag can wirelessly overwrite data). The space (contactless) coupling of the RF signal is realized between the electronic tag and the reader through the coupling component; in the coupling channel, energy transfer and data exchange are realized according to the timing relationship.
The electronic tag is the carrier of RFID technology, and RFID is the abbreviation of Radio Frequency Identification. The term is radio frequency identification. The most basic electronic label system consists of three parts:
Tag: consists of a coupling element and a chip. Each tag has a unique electronic code. The high-capacity electronic tag has a user-writable storage space 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.
RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes target objects and acquires relevant data through radio frequency signals. The identification work can work in various harsh environments without manual intervention. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate.
