Selecting an improper radio technology can cost you several months of time spent on re-engineering the solution. So below we offer our recommendations on when to choose RFID, BLE, and NFC technologies in terms of asset tracking solutions.
RFID
Radio Frequency ID
Uses electromagnetic fields to auto-identify tags attached to objects. Passive tags need no battery — they draw power from the reader.
10cm–10m range
No battery needed
BLE
Bluetooth Low Energy
Broadcasts beacon signals continuously. Gateways or phones pick them up and triangulate position with RSSI. Low power, long battery life.
Up to 100m range
1–3 yr battery
NFC
Near Field Comm.
Short-range, tap-to-read protocol. Ideal for manual check-in/out workflows where a human physically scans an asset tag.
Under 10cm
Passive tags
| Criteria | RFID | BLE | NFC |
|---|---|---|---|
| Read range | 10cm – 10m | Up to 100m | <10cm |
| Tag cost | $0.10 – $2 | $3 – $15 | $0.10 – $1 |
| Power source | Passive (reader-powered) | Battery (active) | Passive |
| Real-time location | Partial (gate-based) | Yes (continuous) | No |
| Infrastructure cost | Medium–High | Medium | Low |
| Best use case | Inventory gates, warehouses | Live location, large sites | Check-in/out workflows |
Which technology to choose?
Choose RFID when you need to scan hundreds of things at once — be it conveyor belts, docking stations, or storerooms of any retail shop. UHF RFID readers can scan 200+ tags within a second. It's perfect for automated warehouses and other logistics centers.
Choose BLE when you need precise continuous localization across your facility — hospitals tracking devices, manufacturing companies controlling tools usage on multiple floors, logistics centers monitoring assets movement. Simply deploy BLE gateways with an interval of 10-30m, and you'll get your own indoor positioning system.
Choose NFC when you don't need continuous localization but want to have audit trails. Tool checkout operations, asset transfers between different shifts, logging some compliance activities — NFC tags are relatively inexpensive, tamper-proof, and don't require any infrastructure whatsoever except for smartphones.
Conclusion
Quick decision support
Scanning many objects at choke points → RFID
Tracking live objects in open spaces → BLE
No infrastructure budget for check-in/check-out → NFC
