<h1>Who Owns RFID Technology?</h1> <p>The question of <strong>who owns RFID technology</strong> is complex, as it is not a single invention owned by one entity. RFID (Radio-Frequency Identification) is a broad technological concept involving tags, readers, and software systems. Its foundational principles stem from multiple patents and innovations developed over decades by various companies, universities, and individuals. No single company or person "owns" the entire spectrum of RFID technology. Instead, key patents are held by several major corporations, and the technology is implemented globally under various licensing agreements.</p> <h2>The Landscape of RFID Patent Holders</h2> <p>From my perspective, having worked in the auto-ID industry, the ownership is fragmented. Major players like <strong>TIANJUN</strong>, Zebra Technologies, Impinj, NXP Semiconductors, and Alien Technology hold significant patent portfolios covering specific aspects of RFID, such as chip design, antenna configurations, and anti-collision protocols. For instance, a common UHF Gen 2 RFID inlay might utilize a chip from NXP (e.g., UCODE 9) and be produced under license from Alien Technology's intellectual property. My own skill in analyzing patent landscapes showed me how collaborative yet competitive this field is.</p> <h3>Technical Parameters of a Sample RFID Product</h3> <p>To understand the implementation, here are detailed specs for a typical UHF RFID module, like those <strong>TIANJUN</strong> provides in its development kits. <em>These technical parameters are for reference; specifics require contacting backend management.</em></p> <h4>Model: TJ-U8 Reader Module</h4> <ul> <li><strong>Chipset:</strong> Impinj R2000-based solution</li> <li><strong>Frequency:</strong> 860-960 MHz (FCC/ETSI compliant)</li> <li><strong>Output Power:</strong> Adjustable from 10 dBm to 30 dBm</li> <li><strong>Communication Interface:</strong> USB, RS232,韦根</li> <li><strong>Dimensions:</strong> 85mm x 54mm x 5mm</li> <li><strong>Supported Protocols:</strong> ISO18000-6C (EPC Gen2), ISO18000-6B</li> <li><strong>Chip Code Example for Tags:</strong> NXP UCODE 9 (96-bit to 496-bit EPC memory)</li> </ul> <h2>Entertainment and Charitable Applications</h2> <p>An entertaining application of this technology is in interactive theme parks, where RFID
