<h2>Introduction</h2>

<p>In the realm of automatic identification and data capture technologies, <strong>RFID</strong> (Radio Frequency Identification) and <strong>QR</strong> (Quick Response) codes are two prominent solutions that have transformed how businesses and consumers interact with information. While both serve the purpose of storing and retrieving data, they operate on fundamentally different principles and are suited to distinct applications. This article delves into the technical workings, advantages, limitations, and use cases of <strong>RFID</strong> and <strong>QR</strong> codes, providing a clear comparison to help you determine which technology best fits your needs.</p>



<h2>How RFID Works</h2>

<p><strong>RFID</strong> technology utilizes radio waves to transmit data between a tag and a reader without requiring line-of-sight. An <strong>RFID</strong> system consists of three key components: a tag (which contains a microchip and antenna), a reader (with an antenna), and a backend system for data processing. When the reader emits radio signals, the tag responds by transmitting its stored data, such as a unique identifier. <strong>RFID</strong> tags can be passive (powered by the reader's signal), active (with their own power source), or semi-active, enabling ranges from a few centimeters to over 100 meters. This technology is widely used in supply chain management, access control, and inventory tracking due to its ability to handle multiple tags simultaneously and operate in harsh environments.</p>

<h2>How QR Codes Work</h2>
<p><strong>QR</strong> codes, on the other hand, are two-dimensional barcodes that store information in a matrix of black and white squares. They require optical scanning, typically using a camera-equipped device like a smartphone, which interprets the pattern to retrieve data. <strong>QR</strong> codes can store various types of information, such as URLs, text, or contact details, and are easily generated and printed. Their operation depends on line-of-sight, meaning the code must be visible and undamaged for successful scanning. This makes <strong>QR</strong> codes ideal for consumer-facing applications like marketing, payments, and information sharing, where simpl The Use of RFID for Human Identity Verification
