[Fig. 1.3.1] Operation Principle of RFID System
The operation principle of LGRF-H 13.56MHz Reader on [Fig. 1.3.1] is as follows :
①
Send 13.56 MHz frequency signal through the antenna of Reader.
②
The Tag located in the read range of the antenna activates IC chip by the rule of
electromagnetic induction.
③
Data information of Tag is resent to the antenna of Reader in the form of reflection
wave.
④
The information obtained through the antenna is sent to the Reader to get the tag
information.
