How it works in Automotive.
The right radio for each job, mapped to your use case.
1 · Identify
Each part is Passive RFID-tagged at goods-in for full just-in-sequence identity.
2 · Sequence
An AGV delivers parts line-side in build order, located live by UWB.
3 · Verify
A wrong part or station is flagged before fitment. The line never builds it wrong.
Passive RFID → identity · UWB → sequence & position · BLE → safety
Common problems in Automotive.
Sub-assembly traceability gap
Sub-assembly logs in spreadsheets, paper, or systems that don't talk to the line MES. Recall scope grows because you can't bound it.
Torque events untied to part
The torque tool fired. Was it tied to part 78421-A or 78421-B? Without RTLS-grade location, the genealogy has a gap.
Finished-goods yard chaos
Hundreds of cars on the yard. Dispatch knows which VIN should be on which truck, but not where the car is right now.
Use cases with a clear payback.
IATF 16949 build genealogy
Passive RFID + UWB at cells with sub-cm accuracy where it matters. Every torque event tied to a specific part by location, not by approximation.
Just-In-Sequence verification
JIS sequence breaks detected in real time, before they stop the line.
Finished-goods yard
BLE on every VIN, anchors across the compound. Dispatch sees position live, picks routes optimally.
EV battery genealogy
Cell-level tracking for EV battery assembly with the audit trail regulators are starting to expect.
Tool calibration
UWB-tagged calibration assets, programme-managed against ISO 17025.
Dealer inventory
Item-level visibility from finished-goods yard through outbound logistics to dealer arrival.
Five use cases in vehicle and component plants
Build records: unit, station, tool and result
Each unit identified at each station and linked to the tool used and its result, so a suspect range comes from the record. Quality traceability
Parts in sequence at the station
Sequenced racks checked against the call-off when they leave the sequencing area and when they reach the station. Just in sequence
Vehicles in rework and the yard found
Every vehicle off the normal flow shows its last known zone and how long it has been there. Yard and finished vehicles
Line feed: tuggers, forklifts and robots
Help choosing the right AMR or AGV for each route first, with VDA 5050 support assessed so robots can share one fleet manager. Fleet orchestration
Returnable racks back from suppliers
Racks and containers read out and back in at the dock, with overdue loops listed by supplier. Returnable assets

Where it pays back in Automotive.
Just-in-sequence (JIS) WIP
Sequence integrity for body-in-white and trim lines. Mis-builds and line stoppages fall, integrated to the MES.
Torque-tool & quality genealogy
Binding every torque event to the VIN gives audit-grade quality records and dramatically narrows recall scope.
Finished-vehicle yard management
GPS and RFID locate finished vehicles in compound yards: find-time and demurrage charges drop sharply.

Relevant case studies
More use cases, in detail.
WIP (work in progress) tracking on assembly line
Problem: Line throughput depends on knowing where every body, engine and kit is at every station. Manual tracking creates variance and stoppages.
Tech mix: UWB or RTLS-grade RFID (ATR7000, RF Controls) on every WIP item, MES integration for routing, dashboard for line balancing.
What to measure: line throughput · WIP variance · time to identify bottlenecks (baseline each before the pilot).
AMR and AGV selection and fleet management
Problem: Modern plants run mixed AGV and AMR fleets from multiple suppliers. Without a common interface each fleet runs in a silo; we assess whether VDA 5050 can close that gap for your vehicles.
Tech mix: VDA 5050-compliant fleet master, BLE-AoA for ground-truth verification, integration with WMS/MES.
What to measure: fleet utilisation · traffic conflicts · coordination across mixed-supplier fleets (baseline each before the pilot).
Forklift-pedestrian collision avoidance
Problem: Forklift-pedestrian collisions are the highest-frequency serious-injury risk in automotive plants.
Tech mix: UWB on forklifts and pedestrian badges, predictive zone alerts, automatic forklift slowdown at proximity threshold.
What to measure: near-miss events · HSE compliance evidence (baseline each before the pilot).
Kit assembly verification (JIS: just in sequence)
Problem: Kits for downstream stations must arrive in the right sequence with the right contents. Mis-sequencing or missing parts halts the line.
Tech mix: Passive RFID on every kitted part, fixed reader at kit-completion station, MES integration for sequence verification.
What to measure: mis-sequenced kits · line stoppages from kit errors · kitting-station rework time (baseline each before the pilot).
Returnable container/dunnage tracking
Problem: Returnable transport items (RTI: bins, totes, dollies, racks) get lost in supplier-OEM loops at significant capital cost.
Tech mix: Passive RFID on every RTI, fixed readers at dock-doors and chokepoints, integration with logistics platform.
What to measure: RTI loss · capital tied up in RTI · supplier-OEM reconciliation effort (baseline each before the pilot).
Paint shop conveyor tracking
Problem: Paint shops are environment-sensitive and high-throughput. Losing a body in the cure oven or mis-routing colour batches causes major rework.
Tech mix: Ruggedised Passive RFID on body skids, environment-tolerant readers, MES integration into colour/cure plan.
What to measure: mis-routes · colour-change compliance · body-tracking accuracy in the paint shop (baseline each before the pilot).
Tool tracking on the assembly line
Problem: Torque tools and calibrated jigs must be present at every workstation. Missing or mis-calibrated tools force line stops.
Tech mix: Passive RFID on every tool, smart-shadow boards, integration with torque management and MES.
What to measure: tool-search time · torque compliance · line stoppages from tool issues (baseline each before the pilot).
Finished-vehicle yard logistics
Problem: OEM and dealer yards hold thousands of finished vehicles; finding a specific VIN for outbound shipment costs 15-45 min per move.
Tech mix: LoRaWAN or GNSS trackers on every vehicle, gateway coverage across the yard, integration with dealer-management system.
What to measure: vehicle find time · dispatch reliability · yard dwell time (baseline each before the pilot).
Quality-escape root-cause attribution
Problem: When a defect is found post-shipment, the manufacturer must identify which workstation, operator and shift caused it. Manual records create attribution gaps.
Tech mix: UWB tracking of WIP through every station, operator badge association, MES capture of every step.
What to measure: root-cause identification time · quality-escape investigation time · IATF 16949 record completeness (baseline each before the pilot).
Predictive maintenance on critical line equipment
Problem: Press lines, robotic cells and conveyors are single points of failure; unplanned downtime costs €5-50k per minute.
Tech mix: Vibration and temperature wireless sensors on critical equipment, LoRaWAN or industrial Wi-Fi backhaul, integration into CMMS.
What to measure: unplanned downtime · share of reactive vs planned maintenance · OEE (baseline each before the pilot).
What you gain
WIP you can see, station by station
Every body, sub-assembly and rework unit has a live location, so supervisors stop walking the line to find it. Measured as WIP location accuracy and time spent searching for units in rework or buffers.
The right part in the right sequence
JIS kits are verified against the build sequence before they reach the station. Measured as sequence errors, mis-builds and line stoppages caused by wrong or late parts.
In earlier work by our advisers: +9 pts OEE. See the case study.
Safer aisles for people and trucks
Forklift-pedestrian proximity alerts and AGV/AMR traffic data show where near-misses cluster. Measured as logged near-misses and alerts per zone, per shift.
Build records for quality escapes
Tool, station and time events attach to each VIN, so a quality escape can be traced to where it happened. Measured as time to root cause and the size of each containment.
Returnables that come back
Containers and dunnage are counted through supplier loops rather than written off. Measured as loop losses, dwell at suppliers and spend on replacement stillages.
A finished-vehicle yard that moves
Every finished vehicle has a known bay and status, so shunters stop searching rows. Measured as vehicle search time, yard dwell and dispatch readiness.
Who else sells into automotive locating and what programmes get wrong.
OEM and Tier-1 shortlists mix UWB specialists, RFID portal packages, MES suppliers, and AMR suppliers promising JIS integrity. Captive SIs and Big-4 manufacturing practices add programme offices. The scarce skill is hybrid design under metal-heavy RF and MES event discipline, not another demo of dots on a body carrier.
What programmes get wrong: one-radio standards for docks, lines and yards; measuring centimetres instead of sequence integrity and line-stop minutes; and letting robot PS redefine WIP tracking. We design independently and sell no hardware or AMRs.
Automotive OEMs and Tier-1s driving locating & RFID.
JIS, WIP and parts-genealogy locating is widespread among European and global automotive groups, including BMW, Volkswagen, Toyota, Jaguar Land Rover, Stellantis and their Tier-1 suppliers. References here are market context for how plants typically buy and integrate RTLS/RFID, not statements that TRACIO works for these OEMs.
AMRs and AGVs in vehicle and component plants
At line speed, a late or wrong delivery stops the line. We help you choose the right AMR or AGV for each flow first, then check what it takes to run them with the rest of the plant.
- Line-side and sequenced parts delivery.
- Kitting and supermarket-to-line moves.
- Body, sub-assembly and rack moves between shops.
- Bringing older AGVs and new AMRs under one plan without stopping production.
- Robot fleet management: one fleet manager for mixed fleets, traffic and priority at crossings, and shared doors and chargers. We check what it takes and help you make it work.
- Integration with MES and material call systems, so moves follow production.
See AMR and AGV consulting, including AMR/AGV fleet management, or book a free scoping call to talk it through. Free briefs: AMR and AGV fleets, and AMR/AGV fleet management.

Frequently asked questions
How does automotive RFID traceability support JIS and WIP tracking?
Automotive RFID traceability and RTLS events confirm the right part at the right station in sequence. JIS / WIP tracking plus IATF parts genealogy give containment and recall evidence without relying on paper travellers: independent readers and tags chosen for the line, not a catalogue.
What does RTLS/RFID deliver on an automotive line?
Sequence verification, full part and torque-event genealogy, WIP and AGV/AMR coordination, and line-side material flow. The visibility that protects takt time and quality.
Does it support IATF 16949 traceability?
Yes, automatic, auditable genealogy of parts, settings and process events aligns with IATF 16949 and OEM traceability requirements.
Can it handle just-in-sequence supply?
Yes, JIS verification ensures the right part arrives in the right build order, alerting before a mis-sequenced unit reaches the operator.
How does it integrate with MES and supplier EDI?
How do you handle the metal-rich plant environment?
With an RF site survey and the right tag and reader selection, designing for metal and interference is core to a reliable automotive deployment.
What does an automotive engagement cost?
It depends on scope and the number of sites. Every engagement is scoped per project and priced in writing before work starts: £3k to £30k per project, or £1,200 a day in the UK. Regional ranges for Europe, North America and other regions are on how we work. Extra sites, on-site RF survey and integration into more than one system of record add to the scope. Hardware and licences are extra: you buy them direct from the supplier, and we don't resell them.
How long does an automotive engagement take?
Discovery usually takes 1 to 5 days on site, supplier selection typically 3 to 6 weeks and a pilot with timings agreed per site, with a gate after each. Rollout is scoped per project. Model-year launches and shutdown weeks usually set the pilot window.
What if the pilot fails?
It stops at the gate. The pilot is judged against written pass/fail criteria agreed before any equipment goes in, so a fail is a clear result, not an argument. You pay no rollout costs and keep the artefacts from each stage: requirements, scored shortlist, TCO, RFP pack, pilot criteria and the measured results. Pilot equipment can be rented, so there is no capex to write off.
Do we need to consult the works council or employees before tracking people?
Usually, yes. Locating people is processing personal data, so under UK and EU GDPR you need a lawful basis, normally a data protection impact assessment, and clear limits on purpose: safety and mustering, not performance monitoring. Where you have a works council or recognised employee representatives, involve them before the pilot. In Germany the works council has a co-determination right over systems that can monitor staff. We design for this from the start: zone-level presence rather than continuous tracks where that is enough, pseudonymised IDs, short retention and role-based access. See GDPR and RTLS.
Who owns the data, and can we avoid supplier lock-in?
You own it. Your data and IP stay yours, with full export. We don't sell hardware, so our advice stays independent. During supplier selection we put data export, open APIs and exit terms into the RFP and contract, so you can change supplier later without starting again.
