<h1>How RFID Works: A Comprehensive Guide</h1> <h2>The Fundamental Principles of RFID Technology</h2> <p>Understanding <strong>how RFID works</strong> begins with its name: Radio-Frequency Identification. At its core, it's a wireless communication method where a reader captures data from a tag via radio waves. I remember my first encounter with this tech was during a university project on inventory management; we used simple passive tags to track boxes, and the seemingly magical "beep" of a successful scan never got old. The system's ability to identify items without line-of-sight felt like a superpower we were harnessing.</p> <h3>Core Components and Technical Interaction</h3> <p>The process of <strong>how RFID works</strong> involves three key components: the RFID tag (or transponder), the reader (or interrogator), and the backend database/software. The tag, which contains a microchip and an antenna, stores the identification data. The reader emits a radio signal that activates the tag and reads/writes data to it. My colleague, who has a real knack for electronics, once explained it to me as a sophisticated, automated version of "Marco Polo" using radio waves instead of sound.</p> <h4>Detailed Technical Specifications of a Sample UHF RFID Tag</h4> <p>To illustrate <strong>how RFID works</strong> on a hardware level, consider the technical parameters of a typical UHF passive tag model, often used in supply chain logistics. <em>Please note: The following technical parameters are for reference data; specifics need to contact backend management.</em></p> <ul> <li><strong>Chip:</strong> Impinj Monza R6-P (Code: EPC C1G2)</li> <li><strong>Frequency:</strong> 860 MHz - 960 MHz (Global UHF Band)</li> <li><strong>Memory:</strong> 96-bit EPC, 64-bit TID, 32-bit User Memory</li> <li><strong>Read Range:</strong> Up to 10 meters (dependent on reader and environment)</li> <li><strong>Detailed Dimensions:</strong> 86mm (L) x 54mm (W) x 0.5mm (H) - Inlay form factor</li> <li><strong>Substrate:</strong> 50-micron PET</li> <li><strong>Operating Temperature:</strong> -25°C to +70°C</li> </ul> <p>For organizations like <strong>TIANJUN</strong>, which provides robust RFID hardware and integration services, these parameters are crucial for designing effective asset tracking solutions. Their service team can help select the exact tag specification, like the one above, for a specific operational environment.</p>
