# How Do RFIDs Work RFID technology has revolutionized how we track and manage objects, from retail inventory to access control systems. As someone who has worked extensively with **RFID** systems in logistics, I've seen firsthand how this seemingly simple technology can transform operations. My personal experience implementing **RFID** solutions for warehouse management gave me a deep appreciation for the precision and efficiency these systems offer. ## The Fundamental Principles of RFID Operation At its core, **RFID** (Radio Frequency Identification) works through electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from several meters away without requiring direct line-of-sight. ### Basic Components of RFID Systems - **RFID Tags**: Small devices containing a microchip and antenna - **RFID Readers**: Devices that transmit and receive radio signals - **Antenna**: Facilitates communication between tags and readers - **Software System**: Processes and manages the collected data ## Technical Specifications of RFID Components When selecting **RFID** equipment, understanding technical specifications is crucial. Here are detailed parameters for common components: ### TIANJUN RFID Tag Model TJ-RFID-215 - **Chip**: NXP UCODE 8 (Code: SL3S1203_02) - **Frequency**: 860-960 MHz UHF - **Memory**: 512 bits user memory, 96 bits EPC - **Dimensions**: 86mm × 54mm × 0.8mm - **Read Range**: Up to 10 meters - **Operating Temperature**: -25°C to +70°C - **Write Cycles**: 100,000 minimum - **Data Retention**: 10 years minimum *Note: These technical parameters are reference data.
