## Introduction to RFID Technology

Radio-Frequency Identification (RFID) represents a groundbreaking wireless communication technology that has revolutionized numerous industries worldwide. At its core, RFID enables automatic identification and data capture through radio waves, eliminating the need for direct line-of-sight scanning required by traditional barcode systems. This technology has become increasingly prevalent in supply chain management, retail, healthcare, manufacturing, and access control systems. The fundamental principle involves using electromagnetic fields to automatically identify and track tags attached to objects, with these tags containing electronically stored information that can be read from several meters away. Unlike barcodes, RFID tags don't require visual contact with the reader, making them suitable for various challenging environments and applications where traditional identification methods prove inadequate.



## Components of an RFID System


### RFID Tags
RFID tags, also known as transponders, constitute the essential data-carrying components of the system. These tags typically consist of an integrated circuit for storing and processing information and an antenna for receiving and transmitting signals. Manufacturers produce three primary types of RFID tags: passive, active, and semi-passive. Passive tags contain no internal power source and instead harness energy from the reader's interrogation radio waves to power their circuits and transmit responses. Active tags incorporate their own power source (usually a battery), enabling them to broadcast signals independently and achieve significantly longer read ranges. Semi-passive tags utilize batteries to power their circuitry while still relying on the reader's energy for communication, striking a balance between performance and power consumption.

### RFID Readers

RFID readers, sometimes called interrogators, serve as the communication hub between tags and backend systems. These devices transmit and receive radio waves to communicate with tags within their operational range. Readers consist of a radio frequency module, control unit, and antenna, which work in concert to send signal The Use of RFID for Human Identity Verification
