Description
https://www.dtbrfid.com/products/rfid-reader/ A complete RFID system is composed of three parts: a reader and an electronic tag which is the so-called transponderand application software system. ts working principle is that the reader transmits a specific frequency radio wave energyto the transponder to drive the transponder circuit to send out the internal data. At this time, the reader will receive theinterpretation data in sequence and send it to the application program for corresponding processing. Based on the communication and energy sensing methods between the RFID chip card reader and the electronic tag, itcan be roughly divided into two types: inductive coupling and backscatter coupling. Generally, low-frequency RFID mostlyadopts the first method, while higher frequency mostly adopts the second method.
