The rfid reader communicates wirelessly with the RFID electronic tag through the antenna, and can read or write the tag identification code and memory data. A typical RFID reader includes an RFID radio frequency module, a control unit, and a reader antenna.
In the radio frequency identification system, electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, communicators, and readers. The space (non-contact) coupling of radio frequency signals is realized between the electronic tag and the reader through the coupling element, and in the coupling channel, according to the timing relationship, the transmission and data exchange are realized.
The rfid reader communicates wirelessly with the RFID electronic tag through the antenna, and can read or write the tag identification code and memory data. A typical reader consists of a high-frequency module, a control unit and a reader antenna.
Among them, electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, communicators, and readers. The space (non-contact) coupling of radio frequency signals is realized between the electronic tag and the reader through the coupling element, and in the coupling channel, energy transmission and data exchange are realized according to the timing relationship.
There are two types of coupling of RF signals that occur between the reader and the tag.
(1) Inductive coupling. The transformer model realizes the coupling through the space high-frequency alternating magnetic field, which is based on the law of electromagnetic induction.
(2) Electromagnetic backscatter coupling: The radar principle model, the emitted electromagnetic waves are reflected after hitting the target, and carry back the target information at the same time, based on the spatial propagation law of electromagnetic waves.
