<h1>USB RFID Reader</h1> <p>In my years of working with access control systems, the <strong>USB RFID reader</strong> has consistently been a cornerstone of reliable and user-friendly security solutions. My personal experience has shown that a well-integrated RFID system can transform security management from a chore into a seamless process. I've always had a knack for identifying the right hardware for specific applications, and selecting the correct <strong>USB RFID reader</strong> is a perfect example of that skill in action.</p> <h2>Technical Specifications and Parameters</h2> <p>From my perspective, understanding the technical backbone is crucial. Here are the detailed specifications for a typical high-frequency (13.56 MHz) <strong>USB RFID reader</strong>, which I often recommend for office and logical access scenarios. Please note: *These technical parameters are for reference data; specifics need to contact backend management.*</p> <h3>Core Technical Indicators</h3> <ul> <li><strong>Operating Frequency:</strong> 13.56 MHz</li> <li><strong>Supported Protocols:</strong> ISO/IEC 14443 A & B, ISO/IEC 15693, Felica</li> <li><strong>Read Range:</strong> Up to 10 cm (depending on tag type)</li> <li><strong>Interface:</strong> USB 2.0 Full Speed (Plug and Play, HID or CDC mode)</li> <li><strong>Power Supply:</strong> Bus-powered via USB (5V DC, ≤100mA)</li> <li><strong>Main Control Chip Code:</strong> NXP PN512 or STMicroelectronics CR95HF</li> <li><strong>Supported Tag Types:</strong> MIFARE Classic 1K/4K, MIFARE Ultralight, MIFARE DESFire, NTAG, I-CODE, etc.</li> <li><strong>Detailed Dimensions (L x W x H):</strong> 98mm x 65mm x 20mm (typical form factor)</li> <li><strong>Operating System Support:</strong> Windows 7/8/10/11, Linux, macOS (with appropriate drivers)</li> <li><strong>Housing Material:</strong> ABS plastic with anti-skid rubber base</li> </ul> <h2>Entertaining and Practical Application Cases</h2> <p>Beyond security, the <strong>USB RFID reader</strong> has some surprisingly fun uses. I once helped a friend set up an interactive museum exhibit for a local school fair. We used a <strong>USB RFID reader</strong> connected to a Raspberry Pi. When children tapped character cards (with embedded RFID tags) on the reader, it would trigger audio stories and animations on a screen. It was a huge hit
