RFID inventory: how to cut warehouse stocktaking and fixed asset audits from days to hours and raise accuracy to 99%
Rfid inventory cuts warehouse stocktaking and fixed asset audit times from up to 2.5 days down to 5 hours while boosting data accuracy from around 94% to over 99%. an rfid reader scans hundreds of tags simultaneously without needing to target each item individually—the operator gathers data simply by walking along the aisles. etisoft, a manufacturer of labels and rfid systems operating since 1993, provides a complete solution including labels, printers, mobile terminals, and inventory software.

What is RFID-based stocktaking?
RFID stocktaking is an inventory method in which products, pallets, tools, or packaging are tagged with RFID tags and read by radio rather than scanned optically like barcodes. An RFID reader doesn’t need a direct line of sight to the label or to scan objects one at a time – it can read many tags simultaneously, even when they’re hidden inside a carton or facing away from the scanner.
Why traditional stocktaking is no longer good enough
In theory, an ERP or WMS system shows the current state of stock at all times. In practice, companies routinely run into discrepancies:
- goods are listed in the system but can’t actually be found,
- tools are assigned to one location but sit in another,
- returnable packaging “disappears” somewhere between processes,
- shortages only surface once a periodic count is carried out.
The more assets a company has and the more complex its processes, the higher the risk of these discrepancies – and a traditional stocktake usually just reveals the scale of the problem rather than solving it.
Traditional stocktaking vs. RFID – results from real deployments
| Area | Before RFID | After RFID |
| Warehouse and logistics | 2.5 days of work, 6 people, accuracy around 94% | 5 hours of work, 2 people, accuracy above 99% |
| Production and returnable packaging | Quarterly count taking 3 days, frequent discrepancies | 4-5 hours, accuracy above 99%, counts can be run more often |
| Retail | 1-2 days, store has to close, accuracy around 75% | Around 2 hours, accuracy 98-99%, counts several times a week |
| Tools and fixed assets | Manual record-keeping, stocktakes spanning several days | A few hours, time spent searching for items cut by 60-80% |
Where RFID delivers the biggest gains
Warehouse and logistics
RFID makes it possible to quickly verify stock levels, check that locations are complete, confirm the presence of pallets and cartons, and reconcile stock against an ERP or WMS system. Beyond the time savings, the biggest benefit turned out to be no longer having to halt warehouse operations for the count.
Production and returnable packaging
In production environments, RFID proves its worth in managing returnable transport items (RTIs), work-in-progress, production components, and assets shared between departments. An added benefit is fewer packaging units getting lost at customer or partner sites – which in turn means less need to buy replacements.
Retail
In stores, the core problem is mismatched stock levels: a product can be physically sitting on the shelf, but if the system shows the wrong quantity or location, the customer simply can’t buy it. RFID adoption has led to better product availability, higher sales, and no more closing the store for stocktaking.
Tools and fixed assets
Here, the biggest benefit of RFID isn’t the counting itself – it’s cutting down the time spent looking for equipment, which in turn improves control over company assets.

The key ingredient: the right RFID labels
How well a deployment works depends not just on the reader, but above all on choosing the right RFID labels – they determine how reliably tags are read, the range achieved, and how durable the solution is. There’s no single tag that fits every use case:
- labels for cartons, pallets, and products,
- on-metal tags for tools and metal surfaces,
- tags built to withstand demanding industrial conditions,
- thin product labels for retail.
As a manufacturer of RFID labels, Etisoft matches the label to the specific environment and process, which has a direct impact on how reliably it can be read.
RFID isn’t just about labels – you need the hardware and software too
RFID printers produce the labels, printing the visible information while encoding the tag at the same time – including specialized on-metal tags.
RFID mobile terminals are the core tool used during a stocktake: the operator moves through the warehouse or production floor and reads many tags at once, without scanning individual labels.
Etisoft’s software turns a read into actual information – it imports data from ERP, WMS, or Excel, collects the readings from the terminal, compares actual stock against expected stock, flags shortages and surpluses, and exports a finished report. That means results are visible during the count itself, not only once it’s finished.
Why RFID rollouts usually start with stocktaking
Stocktaking is typically the first RFID project a company undertakes, because the process is already well understood, the results are easy to measure, and the rollout doesn’t require major organizational change. After a successful pilot, companies usually extend RFID into other areas – tracking material flow, managing returnable packaging, or locating assets.

FAQ
How long does RFID stocktaking take compared with traditional methods?
Depending on the area and the number of audited items, RFID cuts stocktaking time from 1-3 days down to 2-5 hours – for example, from 2.5 days to 5 hours in a warehouse, or from 1-2 days to around 2 hours in a store.
How accurate is RFID-based stocktaking?
RFID deployments show accuracy improving from 75-94% with traditional methods to 98-99%, and in some cases (warehouse, production) even above 99%.
How does RFID differ from barcodes for stocktaking?
A barcode requires scanning each product individually and needs a direct line of sight to the label. An RFID reader picks up many tags at once with no line-of-sight requirement – an operator can read hundreds of items just by walking down an aisle.
Does RFID stocktaking require closing the warehouse or store?
No – one of the main benefits of RFID is that it removes the need to halt warehouse operations or close a store during the count.
Where should a company start with RFID?
Stocktaking is usually the first RFID project, since the process is already well understood, the results are easy to measure, and the rollout doesn’t require major organizational change.
Summary
RFID cuts stocktaking from days to hours and pushes data accuracy above 99% – but that outcome depends on the whole solution working together: the right RFID labels, printers and readers, software, and integration with ERP/WMS systems. For many companies, RFID stocktaking becomes the first step toward broader automation of warehouse and production processes.
