Why technology choice matters
Picking the wrong tracking technology is one of the most expensive mistakes a business can make when rolling out asset tracking. Too often, companies buy GPS trackers for every item in the yard, spend $50,000 on hardware and then discover that most of their tracking needs could have been met with $500 worth of QR code labels. Or they start with QR codes for their fleet and quickly realise they need real-time location data that QR codes cannot provide.
The four main technologies used in asset tracking today are GPS, QR codes, RFID and BLE (Bluetooth Low Energy). Each has a different cost profile, a different data capability and a different operational fit. None of them is universally superior. The right answer for your business almost always involves a combination of two or three, matched to the asset type and the information you need. If you are new to the topic, our introduction to asset tracking covers the fundamentals before diving into technology specifics.
This guide covers each technology in detail, compares them side by side, and gives you a framework for deciding which combination suits your operation.
GPS tracking
GPS (Global Positioning System) tracking uses a network of satellites to determine the precise location of an asset in real time. A GPS device installed on or attached to an asset receives signals from multiple satellites, calculates its position to within 2 to 5 metres, and transmits that position to a cloud platform via cellular network.
How GPS tracking works
A GPS tracking device contains a GPS receiver, a cellular modem (3G, 4G or LTE-M) and either an internal battery or a connection to the asset's power supply. The device calculates its coordinates at a set interval, anywhere from every few seconds to once per day, and sends the data to the tracking platform. The platform plots the position on a map, records the movement history and can trigger alerts based on rules you define: geofence entry or exit, speeding, after-hours movement, or extended idle time.
Where GPS fits
GPS is the right choice for assets that are high-value, mobile and benefit from continuous location monitoring. The classic use cases are:
- Fleet vehicles - track location, route history, speed and utilisation
- Heavy plant - excavators, loaders, cranes and generators that move between construction or mining sites
- Trailers and containers - unpowered assets that are easy to steal and hard to find
- Hired equipment - verify that rented gear is being used at the agreed location
For Australian operations, GPS tracking is particularly valuable for assets operating in remote areas where physical checks are impractical. A mining company with generators scattered across a 200-kilometre radius cannot send someone to check on each one daily, but a GPS tracker confirms location and movement status every few minutes. MapTrack's GPS tracking features support these exact scenarios.
Costs and considerations
GPS hardware costs range from $100 to $400 per device depending on features, battery type and ruggedness. There is also an ongoing cellular data cost, typically $5 to $15 per device per month for the SIM connectivity. Installation varies: some devices are self-install with magnets or adhesive, while hardwired units need a technician.
The main limitation is that GPS does not work well indoors. Satellite signals are blocked or degraded by buildings, which makes GPS unsuitable for tracking assets inside warehouses, workshops or multi-storey facilities. For indoor tracking, BLE beacons are a better option.
QR code tracking
QR (Quick Response) code tracking uses printed labels that encode a unique identifier. When a team member scans the QR code with their smartphone camera, the system records the scan event, including who scanned it, when, and where (via the phone's GPS). The asset's record updates with the new data point.
How QR code tracking works
Each asset gets a durable QR code label applied to its surface. The label encodes a URL or unique ID that links to the asset's digital record. Scanning with a smartphone opens the tracking app, which can display the asset's details, prompt for a status update, initiate a check-out, or launch an inspection form. Every scan creates a timestamped, geolocated record in the platform.
The simplicity of QR codes is their biggest advantage. There is no specialised hardware. Every smartphone made in the last decade can scan a QR code. Labels cost cents to produce and can be printed on weather-resistant materials that withstand outdoor and industrial environments. For a detailed setup walkthrough, see our QR code asset tracking setup guide.
Where QR codes fit
QR code tracking is ideal for assets where continuous real-time location is not necessary but accountability, status updates and service history are important:
- Power tools and hand tools - check-in/check-out tracking, service records, assignment
- Safety equipment - harnesses, gas detectors, fire extinguishers with inspection schedules
- Fixed assets - HVAC units, electrical panels, building infrastructure with maintenance histories
- IT equipment - laptops, monitors, peripherals with assignment tracking
- Hired or shared equipment - accountability for who has what
MapTrack's QR and barcode scanning lets field teams scan assets offline and sync when connectivity returns, which is essential for remote Australian job sites.
Costs and considerations
QR labels cost as little as $0.10 each for basic adhesive labels, up to $2 for heavy-duty aluminium or polyester labels rated for outdoor use. There is no ongoing hardware cost. The only recurring expense is the software platform subscription.
The main limitation is that QR codes only record data when someone actively scans them. If nobody scans an asset for three weeks, the system has no new data for that period. This is fine for most tools and fixed assets, but it is not sufficient for assets where real-time location is a safety or security requirement.
RFID tracking
RFID (Radio Frequency Identification) uses radio waves to read a unique identifier from a tag attached to an asset. Unlike QR codes, RFID does not require line of sight. A reader can detect multiple tags simultaneously within its range, making it significantly faster for bulk scanning.
How RFID tracking works
An RFID system has two components: tags and readers. Passive RFID tags contain a microchip and antenna but no battery. They are powered by the radio signal from the reader. When a reader emits a signal, every tag within range responds with its unique identifier. Active RFID tags have their own battery and can broadcast over longer distances, but they are more expensive and larger.
In asset tracking, RFID readers are typically installed at fixed points such as gate entries, warehouse doors, or tool crib counters. When an asset with an RFID tag passes through, the reader automatically logs the event. Handheld RFID readers can also be used for walking audits, detecting tagged items within a room without needing to see or scan each one individually.
Where RFID fits
RFID is most valuable in environments where speed and volume of scanning matter more than real-time location:
- Depot or warehouse entry/exit - automatically log every tagged item that passes through a gate
- Bulk audits - scan an entire room of assets in minutes instead of hours
- Tool crib management - automatic check-in/check-out as workers pass a reader
- Inventory reconciliation - quickly verify that all expected items are present at a location
Costs and considerations
Passive RFID tags range from $0.50 to $5 each depending on durability and form factor. Industrial-grade tags rated for metal surfaces or extreme environments cost $5 to $15. Handheld RFID readers start around $1,500. Fixed gate readers with antennas cost $3,000 to $10,000 per installation point.
The infrastructure cost is RFID's main barrier. For a single warehouse with two gate readers and a handheld unit, you might spend $8,000 to $15,000 on hardware before adding tags. This makes economic sense for operations managing thousands of items, but it is hard to justify for a business with 200 assets. At that scale, QR codes deliver 80 per cent of the value at 5 per cent of the cost.
BLE beacon tracking
BLE (Bluetooth Low Energy) tracking uses small battery-powered beacons attached to assets that broadcast a signal at regular intervals. Receivers (gateways) installed throughout a facility pick up these signals and triangulate the beacon's position. This provides real-time or near-real-time indoor location tracking.
How BLE tracking works
A BLE beacon is a small device, usually coin-sized, that transmits a Bluetooth signal every one to ten seconds. BLE gateways installed at known positions within a building receive these signals. By measuring signal strength from multiple gateways, the system calculates the beacon's approximate position, typically accurate to 1 to 3 metres depending on gateway density.
Some systems use smartphones as receivers instead of fixed gateways, which reduces infrastructure cost but depends on people being near the beacons frequently enough to provide useful data.
Where BLE fits
- Indoor tracking - warehouses, workshops, hospitals, data centres where GPS cannot reach
- Zone-based location - know which room, floor or area an asset is in
- Tool crib and storage - detect when items leave a designated area
- Occupancy and utilisation - understand how assets move through a facility
Costs and considerations
BLE beacons cost $10 to $30 each, with batteries lasting one to five years depending on broadcast interval. BLE gateways cost $100 to $300 each, and you typically need one gateway per 30 to 50 square metres for accurate positioning. A facility with 2,000 square metres of floor space might need 40 to 65 gateways, costing $4,000 to $20,000 for infrastructure alone.
BLE tracking adds meaningful value in facility-dense environments, but the gateway infrastructure makes it expensive to deploy across large or distributed operations. For outdoor tracking, GPS is more practical. For many Australian field operations where assets spend most of their time outdoors on job sites, BLE fills a niche role rather than being a primary tracking method.

| Bulk scan speed | N/A (automatic) | One at a time | Hundreds per second | Automatic (passive) |
| Offline capable | Store and forward | Yes (with app) | Yes (local storage) | Limited |
Choosing the right mix
The decision is rarely about picking one technology. It is about assembling the right combination for your asset portfolio, budget and operational environment. Here is a practical framework.
Start with asset value and mobility
Sort your assets into tiers based on replacement value and how often they move. High-value mobile assets (vehicles, heavy plant, generators worth over $10,000) justify GPS tracking. The cost per device is a fraction of the asset value, and real-time visibility prevents theft and enables better dispatch.
Medium-value assets that move between sites (power tools, testing equipment, safety gear worth $200 to $10,000) are well served by QR code labels. The tracking cost is negligible relative to the aggregate replacement value of the category.
Low-value consumable items (drill bits, PPE, disposable supplies) are typically not worth individually tracking. Manage these through inventory systems rather than asset tracking.
Consider your environment
If your assets live outdoors on job sites, GPS and QR codes are your primary tools. If you operate from a large warehouse or depot, RFID gate readers may add value for automated check-in/check-out. If you need to track items within a complex indoor facility, BLE beacons fill the gap where GPS cannot reach.
Think about your team
The simplest technology your team will actually use beats the most advanced technology they will resist. QR code scanning requires no training beyond "point your phone at the sticker." RFID gate readers are invisible to the user. GPS runs in the background. BLE beacons are passive. Each of these is low-friction. The adoption risk increases with any technology that adds steps to a field worker's day.
A common combination for Australian operations
Based on what we see across MapTrack customers, the most popular combination for Australian construction, trades, and field service businesses is:
- GPS trackers on fleet vehicles, heavy plant and high-value mobile assets
- QR code labels on tools, small equipment, safety gear and fixed assets
- Manual entries for low-value items tracked at the category level rather than individually
This combination covers 90 per cent of tracking needs for a typical mid-sized operation at a fraction of the cost of an all-GPS or all-RFID approach. If you are planning a rollout, our implementation guide walks through the process step by step.
How MapTrack handles multiple technologies
One of the biggest practical challenges with multi-technology tracking is keeping everything in one system. If your GPS data lives in one platform, your QR code scans in another, and your fixed asset register in a spreadsheet, you have not solved the visibility problem. You have just distributed it across more places.
MapTrack is built to handle GPS-tracked assets, QR-scanned items and manually managed assets within a single asset register. Every asset gets one record regardless of how it is tracked. The GPS position of a vehicle, the last QR scan of a power tool and the manual status update of a fixed air conditioning unit all appear in the same interface, the same reports and the same maintenance schedules.
The mobile app supports QR code and barcode scanning with full offline capability, which matters for field teams working in areas without reliable mobile coverage. GPS data streams in continuously from connected devices and plots on the live map alongside the last-known scan locations of QR-tracked items.
This unified approach means operations managers see the full picture without switching between systems. When planning which technology fits each asset category, the ROI guide in this series helps quantify the business case for each option.
