A New Zealand manufacturer of wheelchair seating and mobility equipment has retired a picking and dispatch process it ran on paper sheets and barcode scans for more than thirty years. The warehouse stopwatch is the part Zebra Technologies chose to headline, but it is the less interesting half of the story. The more consequential change is that Spex Ltd can produce a serial and lot history for every item it ships, which moves a quality investigation or a product recall out of a filing cabinet and into a queryable record.
Zebra announced the deployment on 30 September 2026. Zebra Technologies Corporation (NASDAQ: ZBRA) is a US-headquartered manufacturer of label printers, rugged mobile computers and RFID readers, and one of the larger suppliers of warehouse data capture hardware worldwide. Spex, based in Auckland and part of the Medifab Global Group, builds wheelchair accessories, rehabilitation tools and mobility solutions for people with mobility impairments. That product mix matters to the RFID question, because complex rehab equipment is largely configured to the individual user rather than picked off a shelf in a fixed specification.
The implementation partner was Synergic Technologies, an Auckland integrator that describes itself on its own website as “a certified Zebra Technologies RFID specialist partner in New Zealand”, covering site assessment, RF engineering, middleware configuration and ERP integration.
What Spex deployed
The build uses Zebra MC3300 RFID series mobile computers for picking, ZT400 series industrial printers for the shipping labels, and FX9600 fixed readers to check shipments at a nesting station. Zebra’s MotionWorks enterprise software sits above the hardware, collecting the read events and feeding the ERP system. Workers locate items with the handheld, print the tag at the ZT400, and the fixed reader performs what Zebra describes as a ten second completeness check that updates the ERP automatically.
All of that hardware is UHF RAIN RFID: passive tags with no battery, read over a few metres in the ultra high frequency band, at 865 to 868 MHz in Europe and 902 to 928 MHz in New Zealand and the United States. RAIN RFID is the industry’s working name for the passive UHF ecosystem built on the EPC Gen2 air interface, and it is why this deployment behaves differently from a barcode one. A barcode is a line of sight, one item at a time transaction. A passive UHF tag answers a reader interrogating a whole field, so the unit of work shifts from the item to the order. Terms used here are defined in the RFID glossary.
What the nesting station is actually doing
The ten second check is the most technically interesting element, because it is not a faster barcode scan. A nesting station with a fixed reader and antennas aimed into a defined read zone inventories the entire tag population sitting in that zone, repeatedly, in a single pass. The output is the set of unique tag identifiers present in the field, which the software compares against the expected set for that order. Nothing is handled, nothing is oriented to a scanner, and no one works through a checklist. Verification stops being an act of human attention and becomes a set difference calculated by software, with the read event itself as the evidence. The release makes that point when it says Spex can “verify exactly what was shipped and when”, and that claim does more work than any percentage in the announcement.
The 50 per cent figure, taken apart
Zebra puts the headline gain at “more than 50%” improved picking efficiency. The only evidence offered is a single comparison in the quote from Shaun McDonald, Integrations Engineer at Spex Ltd: “By reducing 15-minute picking tasks to five minutes, Zebra’s RFID solutions have cut our picking times by over 50% while helping us achieve near-perfect dispatch accuracy.”
Those are two different claims in one sentence. Fifteen minutes down to five is a cut of ten minutes, roughly 67 per cent, not 50 per cent. It is also one task rather than an average across a shift, a product range or a site. Saying “over 50%” lets a single best case measurement stand in for a site wide figure while staying technically accurate about it. Both statements can be true at once, and neither tells a reader what the median pick looks like or how many picks resemble the fifteen minute example.
The missing number
“Near-perfect dispatch accuracy” is the phrase to read slowly. It is shaped like a statistic and contains none: no baseline error rate before the deployment, no measured rate after it, and no definition of what counts as an accurate dispatch.
For a medical device manufacturer that omission matters more than it would for a general distributor. The ability to show what was supplied, in what configuration, to whom and when, underpins recall and post market vigilance obligations, so dispatch accuracy there is something a manufacturer may have to evidence to a regulator rather than merely report to its board. The release does describe a real commercial driver: without verifiable proof of dispatch, Zebra says, missing item claims against Spex could trigger automatic and costly product replacements. That is a believable business case. It is not a dispatch accuracy figure.
Brian Van Ginkel, Country Manager for New Zealand at Zebra Technologies, framed the wider argument: “Equipping a connected frontline with RFID technology is essential for modern manufacturers facing growing delivery pressures.” He called the deployment “a powerful example of how real-time inventory visibility empowers workers to modernize operations and deliver reliable service to the customers who depend on their mobility solutions the most.”
Why item level UHF suits assembled to order products
Serialised tagging earns its keep precisely where a barcode struggles, and configured medical equipment is that case. A product code identifies a model. It does not identify the individual unit, the batch its components came from, or the configuration that left the building. Once each unit carries a unique identifier written at manufacture and read at every subsequent touch, movement history becomes a by-product of normal operations rather than a separate clerical task. Zebra says that is what Spex gained: accurate serial and lot histories, faster quality investigations, and the ability to manage recalls and trace items. Comparable deployments are collected under case studies, medical and UHF.
What the release leaves open
What is the tag, and where does it go? On a product assembled to order, with metal frames, foam, fabric and plastics in varying combinations, tag choice and placement are the whole engineering problem. Metal detunes a standard inlay and foam and fabric behave very differently as substrates, so the answer is likely to be a particular inlay or hard tag in a particular position per product family. The release does not say whether tags go on components, on the finished assembly, on the packaging, or some combination.
How does the serial level record map to medical device traceability obligations? Spex is capturing serial and lot history, which is the raw material for unique device identification and recall traceability under the regimes a New Zealand manufacturer exporting internationally has to satisfy. Whether the RFID identifier is tied to a regulatory device identifier, or sits alongside one as an internal record, is not addressed.
And which benefit signed the cheque? The announcement leads with picking speed, but the capabilities described last, meaning recall readiness, serial history and defensible proof of dispatch, are the ones that are hard to achieve any other way. A ten minute saving on a pick is easy to put in a business case. It is also the benefit a manufacturer in a regulated sector is least likely to have built the project around.
