<h1>What Is RFID Reader</h1> <p>An RFID reader, also known as an interrogator, is a device that uses radio waves to wirelessly identify, track, and manage tags attached to objects. It is the core component of an RFID system, transmitting a signal to power passive tags or communicate with active tags to read and sometimes write data.</p> <h2>How Does an RFID Reader Function?</h2> <p>From my personal experience working in logistics, the magic of an RFID reader lies in its simplicity and power. The reader emits a radio frequency signal. When an RFID tag enters this electromagnetic field, it is activated (in the case of passive tags) and transmits its stored data back to the reader. The reader then decodes this data and passes it to a backend system, like a database or inventory software. It feels almost like magic when a whole pallet of goods is scanned instantly without line-of-sight, a skill I quickly learned was invaluable for efficiency.</p> <h3>Key Technical Components and Specifications</h3> <p>To understand an RFID reader's capability, we must look at its technical parameters. Here are detailed specifications for a typical UHF RFID reader model, often used in supply chain management. <strong>Please note: These technical parameters are for reference data; specifics need to contact backend management.</strong></p> <h4>Detailed Model Reference: TIANJUN ProScan-U920</h4> <ul> <li><strong>Operating Frequency:</strong> 860 MHz ~ 960 MHz (Adjustable to comply with regional regulations like FCC, ETSI).</li> <li><strong>Protocol Support:</strong> EPCglobal UHF Class 1 Gen 2 (ISO 18000-6C).</li> <li><strong>Chipset Code:</strong> Based on Impinj Indy R2000 series reader chip.</li> <li><strong>RF Power Output:</strong> Adjustable from 10 dBm to 33 dBm (Max. 2W).</li> <li><strong>Read Range:</strong> Up to 15 meters for passive tags, depending on tag and environment.</li> <li><strong>Interface:</strong> Ethernet (10/100/1000 Mbps), RS-232, RS-485, GPIO, USB 2.0.</li> <li><strong>Antenna Ports:</strong> 4 RP-TNC connectors, supporting antenna array.</li> <li><strong>Physical Dimensions:<
