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 |
