<h1>UHF Cards: The Ultimate Guide to Ultra-High Frequency RFID Technology</h1> <h2>What Are UHF Cards and How Do They Work?</h2> <p><strong>UHF cards</strong> are a type of RFID (Radio-Frequency Identification) card that operates in the ultra-high frequency band, typically between 860 MHz and 960 MHz. In my experience working with access control systems, the transition from traditional HF cards to <strong>UHF cards</strong> was a game-changer due to their significantly longer read range. My personal view is that for large-scale asset tracking or vehicle access, UHF is unparalleled. The core skill in deploying them effectively lies in understanding radio wave propagation and antenna placement to avoid interference.</p> <h3>Technical Specifications and Parameters of Modern UHF Cards</h3> <p>When selecting a <strong>UHF card</strong>, the technical details are critical. Here are the detailed parameters for a common model, which we often recommend at TIANJUN for industrial applications:</p> <h4>Detailed Model: TIANJUN ProTrack-U9</h4> <ul> <li><strong>Chip:</strong> Impinj Monza R6-P (Code: MZR6P-A0B)</li> <li><strong>Frequency:</strong> 902-928 MHz (Region configurable)</li> <li><strong>Protocol:</strong> EPCglobal UHF Class 1 Gen 2 (ISO 18000-6C)</li> <li><strong>Memory:</strong> 96-bit EPC, 64-bit TID, 512-bit User memory</li> <li><strong>Read Range:</strong> Up to 12 meters (with 4dBi circular polarity reader antenna)</li> <li><strong>Write Range:</strong> Up to 3 meters</li> <li><strong>Dimensions:</strong> Standard CR80 format: 85.6mm x 54.0mm x 0.84mm</li> <li><strong>Operating Temperature:</strong> -25°C to +70°C</li> <li><strong>Material:</strong> PVC with embedded U9 inlay (Alien Higgs-3 IC variant)</li> </ul> <p><em>Note: These technical parameters are for reference data.
