RFID in action
Saves millions annually tracking catering carts — fewer lost units, faster inventory, and always the right cart at every catering station and airport gate.
Installed RFID across production lines supplying seats, dashboards, and interior components to major automakers. Assembly accuracy jumped to near-perfect levels, eliminating costly rework.
RFID-guided assembly ensures each vehicle is built to exact customer specification — no incorrect parts, no missed options — while cutting build time almost in half.
How does an RFID tracking system work?
An RFID asset tracking system combines a reader with active or passive tags and asset management software. Understanding the end-to-end workflow — from commissioning a tag to updating your live asset register — is the first step to designing a system that fits your operation.
→The RFID tracking workflow — step by step
Before attaching a tag to an asset, it is "commissioned" — the tag's EPC memory is written with a unique identifier that links it to the asset record in Osolix. This happens automatically when you print from a Zebra RFID printer: the label is printed and the tag is encoded simultaneously. The tag can store asset name, condition, quantity, manufacturer, location, and any custom fields your organisation defines.
The correct tag type is selected for the asset's surface and environment (see the tag guide below) and affixed permanently. The asset record in Osolix is now associated with the tag's unique EPC code. From this point, any reader that detects the tag knows exactly which asset it has found.
Fixed readers mounted at doorways, loading docks, or storage zones read every tag that enters their field — continuously, without any human action. Handheld readers are used for targeted audits, room sweeps, or directed work tasks. Either way, the read event is immediately sent to Osolix over Wi-Fi or LAN.
Osolix matches each incoming EPC code to an asset record, updates the asset's last-seen location and timestamp, and evaluates whether any rule is triggered — for example, alerting a manager if an asset enters an unauthorised zone, or flagging a verification task as complete. Your Fixed Asset Register is updated in real time.
The collected data drives dashboards, compliance reports, depreciation schedules, and physical verification sign-off — all without anyone manually counting, entering, or reconciling spreadsheets. Discrepancies surface automatically; correct data is the default rather than the goal.
System components — what you need
A complete RFID system combines five hardware components with asset management software. Understanding each component helps you design a system sized to your exact needs.
Mounted at doorways, cage entries, or loading docks. Reads every tag that passes within range automatically — no human action required. Examples: Zebra FX9600 (8-port), Impinj Speedway.
A ruggedised mobile computer with an integrated RFID antenna, barcode imager, Wi-Fi, and Bluetooth. Used by staff for spot checks, audits, and directed work. Examples: Zebra TC52, Honeywell EDA52.
The most critical component. Attached to each asset. Available in dozens of form factors for different surfaces and environments. Passive UHF tags are the most common choice for fixed asset management.
Directs radio frequency energy from the reader toward the tags. Fixed readers use external antennas positioned to maximise coverage. Handhelds have an integrated antenna optimised for short-range reading.
The brain of the system. Receives read events from readers, matches tag EPC codes to asset records, triggers workflows, generates reports, and integrates with ERP/finance systems.
Prints and simultaneously encodes the tag's EPC memory during label production. Ensures every tag on every asset is verifiably correct before it leaves the printer. Examples: Zebra ZT610, Honeywell PM45.
RFID frequency ranges explained
Active vs passive — how each type works
Passive RFID tags
Recommended for most deploymentsWhen the reader sends a radio frequency signal, the passive tag harvests that energy and uses it to power its chip and reflect a response signal back to the reader. The reader captures the response and immediately forwards the tag's EPC data to Osolix over the network. No battery. No maintenance. The tag simply works whenever a reader is present.
Because passive tags carry no internal power source, they are smaller, lighter, and far less expensive than active tags. Note that the more data stored on a passive tag, the slightly shorter the effective signal range — a small trade-off for most deployments.
- Office equipment, IT hardware, furniture
- Medical and laboratory instruments
- Supply chain inventory and receiving
- Access control and zone monitoring
- Any portfolio where real-time location isn't required 24/7
Active RFID tags
High-value & real-time trackingActive RFID tags contain an internal battery and a transmitter. They operate in one of two modes: transponder mode — the tag wakes and responds only when queried by a reader; or beacon mode — the tag broadcasts its identity at a set interval (e.g. every 3 seconds), and any reader within range logs the event and passes it to Osolix. Beacon mode enables true real-time location tracking (RTLS) without reader intervention.
When an active tag moves from one reader zone to another, Osolix's inventory management automatically updates the asset's location — no scan required. This is particularly valuable when knowing the exact location of an asset at every moment is operationally critical.
- High-value movable assets (vehicles, heavy equipment)
- Real-time location tracking across large facilities
- Assets with sensor requirements (temperature, shock)
- Security-critical items where constant visibility is required
Four operational advantages you feel immediately
Scan dozens of assets simultaneously — no line-of-sight required
With barcode scanning, you walk to each asset, point the scanner, and wait for a beep — one asset at a time. With RFID, a fixed portal reader at a doorway reads everything that passes through without any human action at all, and field staff run mobile counts today using camera capture or a Bluetooth keyboard-wedge handheld — with native UHF sled bulk-read (capture a whole room in seconds) on the roadmap. What previously took a team three days to audit can be completed in a single day. For large campuses, the labour saving alone pays for the system within the first year.
Real-time data collection and immediate security alerts
Active RFID tags continuously transmit their identity. The moment a tagged asset moves into an unauthorised zone — say, a server being carried through the building exit — Osolix triggers an instant alert to the asset manager and security team. Fixed reader portals log every movement with a timestamp, creating an immutable chain-of-custody record. This level of real-time security is impossible with barcode scanning, which requires a human to initiate every read.
Dramatically improves asset visibility in difficult locations
Traditional barcode scanning requires direct line-of-sight within a few centimetres. That means physically crawling under desks, reaching behind server racks, climbing ladders to reach ceiling-mounted equipment, or moving furniture — just to confirm an asset is where it should be. RFID readers can be several metres away and still get an accurate read. You can sweep an entire server room in seconds or verify all assets on a pallet without opening a single box.
Maximises physical verification accuracy — no asset is ever overlooked
Because RFID readers capture every tag within range simultaneously, the risk of accidentally skipping an asset is eliminated. There is no human to forget a corner of the room, misread a worn barcode label, or transpose digits. Lost or misplaced assets surface automatically — the system flags any tag that was expected in a zone but not detected. Audit accuracy reaches levels that manual and barcode-based processes simply cannot sustain, and audit speed increases by 75–90% in most deployments.
How to choose the right RFID tag
With hundreds of RFID tag options available, selecting the wrong tag is the single most common cause of RFID project failure. Answer these six questions before you commit to any tag.
Fixed portal readers can read an entire pallet. Handheld readers work best at 0.5–3 m. Choose passive for most applications; active if you need real-time location over large areas.
Standard labels need at least a 4 cm × 2 cm footprint. Small assets (pens, instruments) may need a miniature inlay or folded tab tag.
Metal and liquids detune standard antennas. Metal-mount or on-metal tags use a foam spacer or special antenna design to maintain performance.
Look for IP67/IP68 ratings for wet environments. High-temp tags rated to 250 °C exist for autoclave or oven-adjacent use.
Destructible RFID labels break if removal is attempted. Hard tags can be sealed with epoxy. Some tags have a sensor that flags tampering in the tag memory.
Aggressive adhesive for smooth surfaces. Mechanical fastening for assets that are washed or handled roughly. Consider how long the tag must remain readable.
