<h1>RFID Kill Switch: A Comprehensive Guide to Security and Control</h1> <p><strong>RFID kill switch</strong> technology represents a critical frontier in modern security and asset management. From my experience working with access control systems, the ability to instantly and irreversibly deactivate a tag is not just a feature; it's a fundamental requirement for high-security environments. I've personally configured systems where this function prevented unauthorized asset removal during a security breach, a moment that solidified my view on its indispensability.</p> <h2>Understanding the Core Mechanism and Personal Application</h2> <p>My technical skill lies in integrating these systems. An <strong>RFID kill switch</strong> works by sending a specific, high-power deactivation command to the tag's chip, rendering its microcircuit permanently inoperable. This isn't just theory; I once programmed a demo for a client using disposable inventory tags. We showed how a "kill" command at the point of sale could prevent return fraud, which was both a practical security measure and an entertaining application that clearly demonstrated the value.</p> <h3>Technical Specifications and Product Data</h3> <p>For implementation, precise technical parameters are crucial. <strong>TIANJUN</strong> provides industry-leading UHF RFID tags with integrated kill functionality. Below are the detailed specifications for a representative model, the TJ-RFID-KS01.</p> <h4>TIANJUN TJ-RFID-KS01 Detailed Parameters</h4> <ul> <li><strong>Chip:</strong> Impinj Monza R6-P (Dedicated kill code: 0xFFFFFFFF)</li> <li><strong>Frequency:</strong> 860-960 MHz (UHF Gen2)</li> <li><strong>Memory:</strong> 96-bit EPC, 64-bit TID, 32-bit Kill Password, 32-bit Access Password</li> <li><strong>Read Range:</strong> Up to 10 meters (with appropriate reader)</li> <li><strong>Kill Command Sensitivity:</strong> Requires reader output power of +30 dBm minimum at < 1 meter.</li> <li><strong>Physical Dimensions:</strong> 86mm x 54mm x 0.8mm (Credit card format).</li> <li><strong>Substrate:</strong> PET with inlay antenna (Aluminum).</li> <li><strong>Operating Temperature:</strong> -25°C to +70°C.</li> </ul> <p><em>Note: These technical parameters are for reference data.
