# RFID Labels: How They Work ## Understanding RFID Technology Fundamentals RFID labels represent a transformative technology in asset tracking and data management. From my personal experience implementing inventory systems, I've seen firsthand how RFID revolutionizes traditional barcode processes. The seamless scanning capability without direct line-of-sight still impresses me every time I witness bulk inventory being counted in seconds rather than hours. ### The Technical Architecture of RFID Labels RFID labels operate through a sophisticated interplay of components: - **RFID Chip**: The integrated circuit storing data (typically 96-bit to 256-bit EPC codes) - **Antenna**: Conductive material that receives and transmits radio waves - **Substrate**: The material layer supporting the chip and antenna - **Protective Layer**: Often a laminate or overlay for environmental protection What truly fascinates me is how these components create what I consider a "digital twin" of physical items. My technical background helps me appreciate the engineering behind converting radio waves into actionable data. #### RFID Label Technical Specifications (Sample Reference) **Passive UHF RFID Label Example:** - **Dimensions**: 100mm × 20mm × 0.3mm - **Chip Code**: Impinj Monza R6-P (EPC Gen2 V2) - **Memory**: 96-bit EPC + 32-bit TID + 64-bit User Memory - **Frequency**: 860-960 MHz - **Read Range**: Up to 10 meters - **Operating Temperature**: -40°C to +85°C - **Write Cycles**: 100,000 minimum **HF RFID Label Example:** - **Dimensions**: 45mm × 45mm × 0.5mm - **Chip Code**: NXP NTAG 213 - **Memory**: 144 bytes user memory + 32-bit serial number - **Frequency**: 13.56 MHz - **Read Range**: Up to 10 cm - **Data Retention**: 10 years minimum *Note: These technical parameters are reference data.

Once energized, the chip modulates th
