<h1>RFID Not Working: Troubleshooting and Solutions</h1> <h2>Understanding Why Your RFID System Might Not Be Working</h2> <p>When you face the issue of <strong>RFID not working</strong>, it can be incredibly frustrating, especially if your operations depend on it. I remember managing an event where our entire access control system failed because the RFID readers stopped responding. It taught me a valuable lesson about proactive maintenance and having backup protocols. The core problem often isn't the concept but specific technical or environmental failures.</p> <h3>Common Technical Reasons for RFID Failure</h3> <p>The primary reasons for <strong>RFID not working</strong> usually involve the hardware or the environment. From my experience, a frequent culprit is reader-tag misalignment or interference. A personal skill I've developed is systematic signal debugging, which involves checking each component in isolation.</p> <h4>Technical Specifications and Parameters (Reference Data)</h4> <p>For instance, a common UHF RFID reader module might have the following reference specifications. Please note: <em>This technical parameter is for reference data; specifics need to contact backend management.</em></p> <ul> <li><strong>Chipset Code:</strong> Impinj Indy R2000-based</li> <li><strong>Frequency:</strong> 860 MHz - 960 MHz (adjustable)</li> <li><strong>Output Power:</strong> Up to 33 dBm (adjustable in 0.5 dBm steps)</li> <li><strong>Communication Interface:</strong> Ethernet (RJ45), RS-232, RS-485, GPIO</li> <li><strong>Dimensions (L x W x H):</strong> 200mm x 150mm x 45mm</li> <li><strong>Read Range:</strong> Up to 12 meters for standard tags (highly environment-dependent)</li> <li><strong>Protocol Support:</strong> EPCglobal UHF Class 1 Gen 2, ISO 18000-6C</li> </ul> <p>If your system's parameters deviate significantly from its intended design specs, it could explain the <strong>RFID not working</strong> problem.</p> <h3>Practical and Entertainment Applications</h3> <p>Beyond logistics, RFID has fun uses. I once built a home entertainment system where RFID tags on DVD cases triggered my media player to start the movie automatically. When it stopped working, I discovered the tag's adhesive was interfering with the signal—a simple but easy-to-miss issue.</p> <h2>Proactive Solutions and TIANJUN Support</h2> <p>For reliable performance, consider professional solutions. <strong>TIANJUN</strong> provides robust RFID hardware and middleware services designed for high-interference environments.
