Bluetooth vs GPS vs RFID for Asset Tracking

The short version

Bluetooth tags (like AirTag on the Apple Find My network) are best for mobile assets traveling through populated areas — tools, trailers, laptops, returnable packaging, vehicles. Cheap per tag, long battery life, no infrastructure.

Cellular GPS is best for assets that need to be found anywhere, including remote areas with no Apple-device foot traffic. Higher cost per unit, per-device cellular fees, but works everywhere cellular does.

RFID is best for high-volume read-at-a-point inventory: warehouse inbound/outbound, retail inventory, library book circulation. Very cheap tags, but each location where you want a read needs a reader.

What each one actually is

All three technologies put a small tag on an asset. They differ in how that tag's presence and position are detected.

• Bluetooth (BLE) asset tracking: the tag broadcasts a short-range encrypted identifier. Something else has to hear it. With AirTag + Find My, "something else" is any nearby iPhone, iPad, or Mac — hundreds of millions of devices act as passive relays.
• Cellular GPS: the tag has its own GPS receiver, its own cellular modem, and a SIM. It reports its position to a backend directly, over cellular.
• RFID (passive and active): a small tag that responds to a reader's radio signal. Passive RFID tags are cheap ($0.10–$2) but require a reader within a few meters. Active RFID tags have a battery and longer range but cost more ($20–$100+).

Decision matrix

Pick by the shape of the question you are trying to answer.

• "Where is my asset anywhere in the world, even in remote areas?" → Cellular GPS. Accepts the per-device subscription cost to buy universal coverage.
• "Where is my asset right now, when it's usually around people and buildings?" → Bluetooth (AirTag + Find My + a tracking layer like TagLogger). Populated-area coverage at a small fraction of GPS cost, no cellular fee.
• "Did this specific item pass through this specific chokepoint, and how many of them?" → RFID. Purpose-built for high-volume read events at dock doors, store entrances, conveyors, library counters.
• "Is this specific tool inside this specific bay right now?" → UWB-based RTLS, not any of the three above. See AirTag vs RTLS.

Cost comparison for a 200-asset fleet over three years

Bluetooth and cellular GPS price out cleanly against each other — hardware plus a recurring fee per asset. See live pricing for the current TagLogger tier structure.

Why RFID cost is harder to line up on the same table

RFID pricing does not compare row-for-row because the infrastructure cost dominates and is site-specific. Passive UHF RFID tags are cheap ($0.05–$0.50/tag at high volume per CPCon's 2026 RFID chip cost guide), but each fixed reader point costs $500–$4,500 and typical multi-facility deployments run $150,000–$500,000 all-in at the upper end of published industry pricing. Active RFID adds $20–$100+/tag and ongoing battery maintenance on top of the same reader network.

Operationally, RFID tracks events at readers, not continuous location — great for "did it pass the dock door," not for "where is it right now while in transit." That difference in what the technology produces matters as much as the line-item cost.

Where each one struggles

• Bluetooth (BLE) struggles in genuinely remote areas with no Apple-device foot traffic — deep rural, mid-ocean, wilderness. AirTag on Find My is only as good as the nearest relay device.
• Cellular GPS struggles on small assets — most cellular GPS modules are too big to mount on hand tools, laptops, or individual packages without awkward enclosures. Battery life is measured in hours to weeks, not years.
• RFID struggles at tracking mobile assets in transit. A pallet leaves a warehouse and disappears between reader points. RFID is great for "did it pass the door" — not "where is it right now while it's out on the road."
• All three struggle at sub-meter indoor precision. That's a different category — UWB-based RTLS solves it.

Hybrid deployments are normal

Real operations rarely pick one technology for everything. A warehouse might run RFID at the dock doors for inbound/outbound event tracking, AirTag on the forklift fleet and returnable totes for in-transit visibility, and cellular GPS on the over-the-road trucks. Each technology sits where its economics win and stays out of the other two lanes.

The question is not "which technology is best" — it's "which technology is best for each class of asset." That framing usually ends a lot of internal arguments quickly.
