At-a-Glance Comparison: Active vs. Passive RFID
The choice between Active RFID and Passive UHF RFID depends on asset value, required read distance, and tag economics:
- Passive UHF RFID (865–867 MHz): Tags have no internal battery. They harvest electromagnetic energy transmitted by the reader's antenna. Because passive tags cost just ₹3 to ₹8 each and have an indefinite lifespan, they are the undisputed choice for tracking millions of inventory SKUs, apparel, boxes, and library books.
- Active RFID (433 MHz / 2.4 GHz / BLE): Tags contain their own on-board battery and transmitter, continuously broadcasting beacon signals up to 100+ meters away. They are used for real-time location tracking (RTLS) of high-value equipment, shipping containers, and vehicles in open yards.
| Metric / Feature | Passive UHF RFID (RAIN) | Active RFID / BLE |
|---|---|---|
| Power Source | Internal Battery: ❌ None (RF energy harvesting) | Internal Battery: ✅ Yes (Lithium Coin/Pouch) |
| Tag Lifespan | Indefinite (20+ Years) — Zero maintenance | 3 to 7 Years (Requires battery swap or tag replacement) |
| Read Distance | Up to 10–15 meters (30–50 ft.) | Up to 100–300 meters (300–1,000 ft.) |
| Tag Unit Cost | ₹3.50 to ₹8.00 per label | ₹800 to ₹3,500+ per active beacon |
| Reader Cost | ₹55,000 to ₹1,50,000 per reader/portal | ₹25,000 to ₹85,000 per gateway/anchor |
| Best Application | High-volume retail, warehouse inventory, manufacturing WIP | Vehicle yard tracking, hospital crash carts, container ports |
