How a warranty claim is raised and resolved.

A warranty is only useful if you know how to use it. This page states what is covered in principle, what is excluded, and exactly what happens between raising a fault and getting a resolution.

COMMERCIAL / DOCUMENT 06 SECTIONS How a quote, a shipment and a warranty claim actually work.

01 / COMMERCIAL

What the warranty covers

We warrant the delivered hardware against manufacturing defect in the configuration actually shipped, under the operating conditions stated for that model. If a unit fails to perform as specified because of how it was made, we are responsible for putting that right.

  • The warranty attaches to the model, variant and configuration named on the order confirmation.
  • The warranty term for each product is stated on the order confirmation for that order.
  • Consumables and media — tags, labels, inlays, ribbons — carry their own stated terms because their life depends on the surface and environment they are applied to.
  • Where a workflow was validated by a sample or proof of concept with us, the validated configuration is part of what we support.
We do not publish a single warranty duration across the catalogue. Durations differ by product family and are set by the manufacturer of each item, so a site-wide number would be wrong for most of the range.

02 / COMMERCIAL

What the warranty does not cover

Exclusions are stated plainly, because discovering them during a claim is worse than reading them now.

  • Damage from physical impact, liquid ingress, over-voltage or conditions outside the published operating range.
  • Unauthorised modification, repair or firmware changes outside the supported release.
  • Configuration changes made after handover that invalidate the tested baseline, where the fault follows from that change.
  • Normal wear on wearable or consumable items, and read performance that changed because the item, the tag placement or the environment changed.
  • Failure of third-party infrastructure — network, power, host hardware or software — that the equipment depends on.
This is a business-to-business warranty. It sits alongside, and does not replace, any statutory right that applies in your jurisdiction and cannot be excluded.

03 / COMMERCIAL

Raising a claim: what to send

Most claims resolve faster with detail than with a return. Send these six things and the first reply is usually a diagnosis rather than a request for more information.

  • Order or invoice reference, and the model and serial or batch identifier.
  • Who the order was placed by, and who is technically handling the fault.
  • What the workflow was doing when the fault appeared, and whether it worked before.
  • What has been tried already, and what the result was.
  • Evidence of the fault — photographs, a reader log, a video of the failure, or the exact error returned.
  • The operational impact, so we can rank the response appropriately.
Do not ship anything back before you have a return authorisation. An unauthorised return cannot be tracked through customs, and we may not be able to receive it.

04 / COMMERCIAL

How a claim is handled

Every claim moves through the same four stages, so you always know where it stands.

  • Triage — we confirm receipt, restate the fault in our own words, and tell you who owns it.
  • Remote diagnosis — configuration review, log analysis, and a reproduction attempt on our side or with a matched unit.
  • Return authorisation, where a physical inspection is the only way forward. We issue the authorisation and the shipping instruction together.
  • Resolution — repair, replacement with an equivalent or better unit, or credit, decided against what the inspection found and stated in writing.
Where a fault is urgent, say so at the first message and describe the operational impact. Urgency is a legitimate input; we would rather know than guess.

05 / COMMERCIAL

Dead on arrival

A unit that fails to function on first commissioning is treated as a priority case, not a routine claim. Report it as soon as it is found, keep the packaging, and do not attempt a repair.

DOA is judged against the shipping and inspection record, so early reporting matters. A unit put into production and then found faulty is a standard claim, not a DOA.

06 / COMMERCIAL

After the warranty term

Equipment does not stop being supported when its warranty ends. Fault diagnosis, repair, spare parts and replacement remain available for equipment we supplied, quoted per case.

For long-lived installations, we recommend recording the configuration, tag placement, reader settings and acceptance evidence at handover. That record is what makes a later fault diagnosable.
