# Active and Passive RFID Tags: A Comprehensive Guide
## Understanding the Core Differences
**Active and passive RFID tags** represent two fundamental technologies in radio-frequency identification systems. My journey into RFID technology began during a logistics optimization project for a major retailer. I discovered that my natural aptitude for systems analysis helped me quickly grasp the operational distinctions between these tag types, which fundamentally changed how I approached inventory management solutions.
### Technical Specifications and Parameters
For **active and passive RFID tags**, the technical specifications vary significantly. Here are detailed parameters for a typical series:
**Active RFID Tag Example (Model AT-950U):**
* **Power Source:** Integrated 3.6V Lithium battery (ER26500)
* **Battery Life:** 5-7 years (with 30-second beacon interval)
* **Operating Frequency:** 433.92 MHz (or 2.4 GHz depending on region)
* **Read Range:** 100-150 meters (open environment)
* **Chipset:** NXP UCODE 9 (or Impinj Monza R6 for specific variants)
* **Memory:** 512 bits user memory, expandable to 8KB
* **Dimensions:** 86mm x 54mm x 13mm (standard housing)
* **Environmental Rating:** IP68 (dust/water resistant)
* **Operating Temperature:** -40°C to +85°C
* **Communication Protocol:** ISO 18000-7 (for 433 MHz) or proprietary
**Passive RFID Tag Example (Model PT-35 inlay):**
* **Power Source:** No internal battery; powered by reader signal
* **Operating Frequency:** UHF 860-960 MHz (global variations)
* **Read Range:** Up to 12 meters (depending on reader power and environment)
* **Chip:** Impinj Monza R6, Alien Higgs-3, or NXP UCODE 8
* **Memory:** 96-128 bits EPC, 64 bits TID, 32-512 bits user memory
* **Dimensions:** 100mm x 15mm (typical label size; chips measure 0.5mm x 0.5mm)
* **Environmental Limits:** Varies by encapsulation (paper, PET, epoxy)
* **Operating Temperature:** -25°C to +70°C (standard)
* **Protocol Standards:** EPCglobal Gen2v2 (ISO 18000-63)
