# RFID Tag with LED Light: Enhancing Visibility and Functionality ## What is an RFID Tag with LED Light? An **RFID tag with LED light** represents a significant advancement in radio-frequency identification technology. By integrating a light-emitting diode (LED) into a standard RFID tag, these devices provide both identification capabilities and visual feedback. From my personal experience working in warehouse logistics, the moment we implemented these illuminated tags was transformative. Suddenly, locating specific high-priority items on crowded shelves became intuitive—the blinking light cut search times dramatically. This isn't just a minor upgrade; it’s a practical fusion of digital data and physical indication. ## Technical Specifications and Parameters of RFID Tags with LED When evaluating an **RFID tag with LED light**, understanding its technical foundation is crucial. Here are detailed specifications for a typical active UHF model. *Please note: These technical parameters are for reference data; specifics need to be confirmed by contacting backend management.* * **Operating Frequency:** 860 - 960 MHz (UHF Band) * **Protocol Compliance:** EPCglobal UHF Class 1 Gen 2 (ISO 18000-6C) * **Integrated Circuit (Chip Code):** Impinj Monza R6-P (or similar, e.g., NXP UCODE 8) * **LED Specifications:** * Color: Typically Red or Green (High-brightness SMD LED) * Viewing Angle: 120 degrees * Luminous Intensity: 20-30 mcd * **Power Source:** 3V Coin Cell Battery (e.g., CR2032) for active/semi-active tags; Passive tags are powered by the reader's signal. * **Dimensions:** 86mm x 54mm x 6mm (Standard credit card size, but varies). * **Memory:** * EPC Memory: 128 bits * User Memory: 32 bits * TID Memory: 48 bits * **Read Range:** Up to 15 meters for active models (passive models: up to 10m). * **Housing Material:** ABS Plastic or Polycarbonate (IP65 rating common). * **Activation Method:** LED can be triggered by a specific EPC read command or a dedicated "Blink" command from the RFID reader. ## My View on the Practical Advantages In my opinion, the primary value of an **RFID tag with LED light** lies in its dual-purpose design. It bridges the gap between the digital inventory system and the physical world. A skill I've developed is configuri
