What is RFID Technology? Operating Principle of an RFID System

RFID stands for Radio Frequency Identification, a technology used for identifying objects via radio waves. RFID technology allows users to identify objects through a radio frequency transmission and receiving system, providing the most efficient, accurate, and quick management.

What Are the Main Components of an RFID System?

A complete RFID system typically consists of both hardware and software components:

RFID Hardware Components:

• RFID Tag: RFID tags are designed to store and transmit information through radio waves, enabling the identification of objects. An RFID tag is a tracking system that uses radio frequency to search for, identify, track, and communicate with items and people.
• RFID Reader: Known as an RFID reader, this device collects information from the RFID tag and is used to track individual items. Radio waves are used to transmit data from the tag to the reader. There are three common types of readers: passive readers for active tags, active readers for passive tags, and active readers for active tags.
• RFID Antenna: The antenna allows the transmission and reception of wave signals, which activate and communicate with the tag.

RFID Software: Integrating business management software systems like ERP, MES, PLM, SCM, etc., allows the data processed by the server to be used for making effective business strategies and decisions.

Operating Principle of an RFID System

The RFID reader emits electromagnetic waves at a specific frequency, and any RFID tag within the operational range senses these waves, absorbing the energy and transmitting its identification code back to the RFID reader. At that moment, the RFID reader can identify which tag is active within the electromagnetic field.

Advantages of RFID Technology
