Overview of RFID System Structure: Transponders and Read/Write Modules

This document outlines the general structure of RFID systems, focusing on transponders (tags) and read/write modules (RWMs) across varying frequencies. It details the characteristics of plastic and metallic transponders, including their temperature tolerance and embedding capabilities. Additionally, it discusses the different types of RWMs, including handheld and USB options, and various interfaces such as LF and HF protocols. The integration possibilities with fieldbus and Ethernet connections are also highlighted, providing a comprehensive view of RFID technology applications.
