Production plants require a constant flow of materials, tools, equipment and work-in-progress items. If your personnel don't know where the items or when they were last moved, the smallest task can be difficult to orchestrate.
An misplaced tool can hold up a maintenance operation. A materials bin left in the wrong location can break a production run. Mistakes in tracking inventory can cause over-ordering, or cause you to run out of stock.
By providing real-time tracking, asset tracking can mitigate these issues through linking physical assets to digital systems of record that track the ID, location and movement of the assets.
In this post, you will learn more about asset tracking, the technologies you'll encounter, and recommendations for dev teams and manufacturing teams interested in tracking.
What Is Real-Time Asset Tracking?
Real-time Asset Tracking The real-time tracking of physical assets, either as a function of location or movement, is the practice of utilizing sensor- enabled ID and positioning.
Depending on the application, tracked assets may include:
- Production machinery and tools
- Raw materials and components
- Work-in-progress products
- Returnable containers and pallets
- Mobile carts and material-handling equipment
- Vehicles moving around manufacturing facilities
A tracking solution is a system that usually involves physical tags/devices, readers or equipment for positioning, networking, data-processing tools and a graphical user interface.
The system collects tracking events and provides access to apps that help employees track their assets and see where they're moving.
Some technologies do not support location in real-time. For example, an asset is only tracked when it passes through a detection area, such as a reader, or when it enters a detection zone, in the case of estimated location data.
- Better Visibility Across Manufacturing Facilities
Many big factories have multiple warehouses, production lines, storage, and assembly lines.
Items and supplies are transported between both sites during the day. If there's no tracking system in place, staff spend an excessive amount of time looking for things.
A tracking dashboard can inform a supervisor where the asset has already reported the location or where it is reporting the location at present.
For instance, if the maintenance team requires a shared tool, they could potentially check the most recently recorded location instead of making inquiries to various departments.
This can be less searching and easier funding allocation.
- Reduced Equipment Misplacement
Machinery, equipment and tooling can be expensive.
Shared equipment can end up in a different department when moved without recording where it was taken from.
Tracking of assets can help maintain a digitized movement history. An RFID system would be able to log tagged assets as they go by the reader locations while an indoor positioning system could give an estimate of the asset's location within a defined area.
Using this information can enable teams to identify missing gear and enhance the management of shared resources.
But the accuracy of detection relies on tag placement, reader coverage, the existing infrastructure set-up and the process environment around it.
- Improved Inventory Management
Accurate inventory for good production planning.
Manufacturers require accurate information about the levels and locations of raw materials, components, and products that are part finished.
Inventory processes can be monitored through a tracking system by recording the following:
- Materials entering a storage area
- Containers moving between departments
- Components reaching a production station
- Finished products moving to dispatch
- Assets being transferred between locations
By integrating these events with inventory management software employees can compare recorded physical movements with anticipated stock.
As an example, an automotive plant could deploy RFID readers at a few locations at its warehouse, measuring off specific channels for goods entering or exiting containers of material.
This isn't to say you automatically get a perfect inventory. You still require systems for processing unscanned tags, repeat events, faulty asset records, and items that fly past the fences.
- More Efficient Production Coordination
It is important to have the equipment and materials moving along at the proper time.
The line may be delayed if a needed component cannot get to a production station. Equipment that is not easy to find may hinder maintenance and production.
By monitoring, managers can know the location of goods and how long they stay in a specific spot.
For instance, if a container remains in a staging area longer than it should, the movement history of the container might assist a supervisor in tracking down the source of the delay.
This can also help in interaction between the warehouse, production and logistics team.
Visibility is not the same as automatic optimization: tracking data can identify an issue, but fixing it may require altering scheduling, staffing, or even the way that materials are handled.
- Support for Maintenance and Equipment Management
Teams working on repairs frequently use common devices, spare parts, and tools.
Knowing where these supplies are located can assist employees in locating them prior to beginning repairs or inspections.
For instance, a maintenance team supporting multiple production lines might view an asset dashboard to find out when a common diagnostic device was last located.
Tracking can also be integrated with a CMMS (computerized maintenance management system) to offer more context for equipment records.
But location tracking by itself cannot help anticipate the failure of an engine. To make predictive maintenance work, additional information is required, such as temperature, vibration, pressure or operating-performance data.
- How Tracking Technologies Differ
The technology applied for an asset tracking project involves variety of factors which include environment, degree of accuracy, asset category and budget.
RFID (Radio Frequency Identification)
RFID (radio frequency identification), identifies tagged objects with readers. It can be used for inventory identification and tracking movement at specific checkpoints.
UWB (Ultra-Wideband)
Real-Time Location Systems based on UWB and leveraging the availability of the right anchors and tags with calibration can also deliver accurate indoor location. This is advantageous when more detail is needed for the application.
BLE (Bluetooth Low Energy)
BLE is able to provide proximity-based tracking and location services, when low-power devices and gateways are in use. Real accuracy will vary, depending on deployment.
GPS (Global Positioning System)
GPS is a system that can track assets and vehicles in outdoor environments where GPS signals from satellites are present. It is not designed for high accuracy indoor positioning, as building walls will compromise the GPS signals.
Multiple techniques are employed at some locations. For instance, GPS provides vehicle visibility outdoors, while RFID and UWB technology offers support for certain in-plant activities.
- Understanding the Tracking Data Flow
Having insight on how data tracked flows through a system is just as critical for developers and system integrators as it is for choosing a hardware product.
Tracking can proceed as follows:
- An asset receives a unique identifier.
- A tag or associated device interacts with a reader or location infrastructure.
- The infrastructure generates a tracking event.
- The event is sent to an application or data-processing service.
- The event is validated and saved.
- The relevant information is presented through a dashboard or combined application.
Here is an example of a tracking event:
``json
{
"asset_id": "TOOL-1042",
"location_id": "ASSEMBLY-ZONE-03",
"eventtype": "locationupdate",
"timestamp": "2026-11-03T08:30:00Z",
"source": "uwb_rtls"
}
``
-This is just a simplification, -not a universal tracking standard.
This event might be used by an application to update the asset's last known location. Developers in a production environment would need to address device identification and authentication, event validation, duplicate messages, dropped network connections, and timestamp consistency.
Another consideration is stale data. If a device is no longer updating, you do not want an application to keep displaying older data as if it were real-time.
