Summary – The supply chain remains vulnerable: asset theft and loss, lack of visibility, security gaps, reactive maintenance, high maintenance costs, delivery delays, stockouts or overstocks, rising insurance premiums, operational inefficiencies, negative ROI. Solution: audit your assets and context → define a technology mix (barcodes, RFID, BLE, UWB, GPS/LoRa) → deploy an RTLS integrated with your WMS/ERP and BI.
At a time when supply chain resilience is a strategic priority, loss and theft of logistics assets can have significant financial and operational repercussions.
Implementing a robust asset tracking system not only mitigates these risks; it also enhances visibility, security and maintenance efficiency in warehouses, transportation and field operations.
Technologies such as barcodes, RFID, Bluetooth Low Energy (BLE), UWB, Wi-Fi, GPS and LoRa, combined within RTLS architectures, offer varying levels of precision and functionality depending on the context.
This article clarifies the distinctions between asset management, inventory and real-time tracking, and provides a technological overview to guide decision-makers in selecting and integrating the most relevant solutions.
Challenges, Definitions and the Specificity of Real-Time Tracking
The security and visibility of logistics assets have become key factors in protecting investments and optimizing operations. Tracking systems provide a technological response to theft, loss and proactive maintenance challenges through continuous data collection and analysis.
Differences Between Asset Management, Inventory and Tracking
Asset management encompasses all processes aimed at maintaining and maximizing the value of a company’s equipment portfolio, from acquisition to decommissioning. It focuses on budget planning, accounting and asset lifecycle management. Inventory, by contrast, is limited to the stock status at a given moment, without necessarily offering visibility into movements or continuous usage status. Asset tracking, and specifically RTLS (Real-Time Location System), goes further; it enables the continuous localization of an object or vehicle, tracks its route, and triggers alerts in case of anomalies (zone intrusion, suspicious immobilization, etc.). This level of detail is essential for securing the supply chain and reducing losses. While inventory is often conducted periodically and manually, tracking relies on sensors and beacons to automate data collection. The returned data enriches maintenance tools and decision-making platforms, promoting predictive management and resource optimization.
Specificity of RTLS Systems
An RTLS combines localization technologies, sensors and a central platform to process and visualize data in real time. Unlike spot-scanning solutions, it provides continuous traceability that secures assets in transit and in warehouses.
Economic Impacts of Asset Loss and Theft
The disappearance or theft of a forklift, container or piece of equipment costs, on average, several thousand francs, not to mention service interruptions and administrative fees. These incidents result in delivery delays, higher insurance premiums and degraded customer satisfaction. Beyond direct losses, traceability failures can cause overstocking or stockouts, penalizing financial performance. Costs associated with replacing irretrievable assets and filing claims weigh on margins, especially in low-value-added sectors. Example: a Swiss SME in logistics services saw an 18 % increase in operational costs in one year due to undetected pallet thefts. Implementing an RTLS that combined GPS and container-opening sensors reduced these incidents by 85 %, demonstrating that continuous visibility leads to real savings and a rapid return on investment.
Tracking Technologies in Logistics
Technological choice depends on cost, performance and environmental constraints, as no single solution covers all needs. Each technology family has specific strengths and limitations that should be combined for optimal tracking.
Barcodes and QR Codes
Barcodes and QR codes are the most economical means to identify items or pallets. They require manual or semi-automated scanning with a handheld device, providing identification accuracy without real-time location. These technologies suit periodic verification and inventory operations when scan frequency is sufficient to prevent significant stock discrepancies. They easily integrate with existing ERP platforms without heavy infrastructure.
Passive and Active RFID
Passive RFID operates with battery-free tags activated by a radio field emitted by the reader. It is suitable for spot tracking of pallets on conveyors or at warehouse exits. Limited range and reader infrastructure dependency require a structured deployment. Active RFID, equipped with a battery and sometimes sensors (temperature, shock), continuously emits a signal picked up by antennas. It allows near-real-time tracking over longer distances and the collection of valuable contextual information for predictive maintenance or regulatory compliance. Example: a Switzerland-based industrial supplies distributor equipped its mobile carts with active RFID tags combined with temperature sensors. This solution anticipated malfunctions and reduced storage-condition-related disruptions by 30 %, demonstrating the effectiveness of active tags for critical equipment management.
Bluetooth Low Energy, UWB and Wi-Fi
Bluetooth Low Energy (BLE) is favored for long-duration indoor tracking and multi-device environments. BLE beacons consume little power and connect to gateways or smartphones to transmit location. Their accuracy often reaches a few meters, sufficient for most warehouses. UWB (Ultra-Wideband) offers the highest precision, on the order of tens of centimeters, and resists interference well. It integrates with RTLS systems to locate tools or vehicles in high-density areas. Initial investment is higher, but the reliability gain often justifies the expense in industrial settings. Wi-Fi, leveraging existing infrastructure, provides a low-incremental-cost tracking solution. Accuracy is limited (5 to 15 meters), making this technology suitable for applications where coarse localization is acceptable, such as tracking non-sensitive carts or pallets.
GPS and Long-Range Networks (LoRa)
GPS remains the standard for global tracking of vehicles and containers, offering worldwide coverage and meter-level accuracy. It requires satellite reception and consumes more power, which leads to using hybrid GPS tags or sleep modes to optimize battery life. LoRa is an alternative for large sites without dense reader infrastructure. Its long range and low power consumption suit remote sensors and outdoor environments, but it offers limited precision of several tens of meters. Choosing between GPS and LoRa depends on positioning frequency, satellite coverage availability and battery constraints. They are often combined to switch between global tracking and fine localization according to operational needs.

Selecting the Right Technology for Your Specific Needs
The optimal technology mix arises from analyzing your assets’ profile and your precision and tracking frequency requirements. Decisions should consider asset type, volume, operating environment and additional data to collect.
Assessing Asset Type and Volume
For a few hundred tags or labels, RFID or BLE solutions may suffice, as reader infrastructure remains manageable and per-asset cost is moderate. Beyond that, deploying additional gateways or strengthening the Wi-Fi network becomes necessary to handle data traffic. For large vehicle fleets, GPS paired with a telematics platform is justified by its coverage and robustness, even if the initial cost is higher. Investment should be weighed against reduced theft, route optimization and lower maintenance expenses. Finally, tracking small parts or tools often requires ultra-precise solutions like UWB, as the unit value makes loss particularly critical. Limited volumes keep the total cost of ownership of such a system in check.
Determining Precision and Tracking Mode
Meter-level localization precision is usually sufficient for large assets in warehouses. In a dense workshop with co-located machines and operators, centimeter-level granularity becomes necessary to avoid collisions and optimize workflows. Real-time tracking (RTLS) implies continuous data collection and a robust reception network. When a simple entry/exit zone notification suffices, less costly, intermittent passive technologies (RFID scanning, QR codes) are preferred to limit energy consumption.
Considering Environment and Associated Data
Indoors, radio interference is common and impacts GPS and Wi-Fi signal performance. UWB or active RFID solutions adapt better to these conditions, ensuring service continuity even with metal obstacles. Outdoors, satellite coverage and LoRa range become critical. Sensors must withstand rain, shocks and temperature variations. Active tags are then preferred to incorporate environmental sensors (humidity, temperature) and ensure traceability of transport or storage conditions. Collecting additional data, such as power consumption or vibration, enriches predictive maintenance algorithms. This operational context directly influences the choice of sensor, battery and communication protocol.
Typical Use Cases and Suitable Solutions
Each logistics scenario calls for a dedicated technology portfolio, often combining multiple solutions. Integrations with WMS, ERP or BI are essential to turn tracking flows into operational and strategic decisions.
Fleet and Container Tracking
GPS and telematics are the pillars of road transport monitoring. They provide position, speed and consumption data, enabling route optimization and service time forecasting. Telematics platforms connect to ERP systems to synchronize maintenance schedules and to BI tools to analyze fleet performance. Alerts for route deviations or prolonged stops enhance security. In many projects, adding onboard IoT sensors measuring temperature and vibration completes traceability, especially for sensitive or temperature-controlled goods.
Retail Stock Monitoring
Barcodes and QR codes paired with mobile readers remain the most widespread solution for point-of-sale operations. Their low cost and ease of implementation ensure fast, reliable inventory. To boost responsiveness, integrating passive RFID on shelves and automatic doors allows real-time stockout alerts and speeds up replenishment. Data syncs directly with the WMS to adjust supplier orders. BI analytics features, combined with these technologies, provide precise metrics on stock turnover, store zone performance and sales forecasts, supporting merchandising strategy.
Tool and Small Equipment Tracking
Hand tools and measuring instruments easily get lost in large or shared environments. BLE and UWB deliver precise location without heavy infrastructure, via beacons attached to storage racks. Employees can locate a tool using a mobile app or a fixed station, reducing search time and production downtime. Movement history also identifies overuse or unauthorized station use. For high-turnover equipment, active RFID tags extend battery life and can transmit usage state or next calibration date.
Industrial Mobile Equipment Tracking
In industrial settings, co-existing heavy machinery and high-risk zones require ultra-precise localization. UWB-based RTLS systems offer centimeter-level granularity essential for operator safety. The central platform aggregates position data, detects hazardous proximities, and triggers alerts on operator tablets. Analytics create traffic maps and optimize workstation layouts. Combining BLE or RFID for personnel and machine identification enables conditional access and tracks intervention history for regulatory maintenance.
Turn Asset Visibility into a Competitive Advantage
Asset tracking is more than localization: it becomes a performance, safety and predictive maintenance lever when integrated into your processes and business systems. By combining the right technologies—barcodes, RFID, BLE, UWB, GPS or LoRa—and coupling RTLS with analytical platforms, you create a modular, scalable and secure ecosystem.
