RFID Tags for Automotive Manufacturing
Give every part carrier, fixture and container a serialized identity that survives the line, so traceability happens automatically.
Design for the real reading environment
Automotive production is serialized by nature (VINs, lot codes, torque records), but much of that identity still travels on paper travelers and hand-scanned barcodes. RFID moves identity onto the carrier or the part itself: stations read work in progress as it arrives, and the genealogy record builds without manual scans.
Antenza supplies UHF tags for carriers and skids, tooling and fixture registers, kanban and container loops, and part labelling. Listed inlays include 93 × 19 mm Alien Higgs-9 and Higgs-10 designs and a slim 60 × 4 mm NXP UCODE 9 inlay; metal-heavy points use our on-metal tags.
Where identity leaks on the line
- 01
Paper travelers
Route sheets get wet, torn and mis-keyed; the genealogy record is only as good as the last manual scan.
- 02
Fixture and tooling drift
Calibrated fixtures and dies move between lines and plants; audits find them late and maintenance slips.
- 03
Container loops without owners
Racks and stillages cycle between OEM and suppliers with no per-asset record of where they are or how many trips they have made.
- 04
Metal everywhere
Standard labels fail on steel carriers and racks, which are the assets that matter most on a line.
How Antenza supports automotive tracking
On-metal where it matters
On-metal labels from 40 × 25 to 80 × 35 mm mount directly on carriers, racks and machine beds.
User memory for process data
Alien Higgs-9 offers up to 688 bits of user memory and 200,000 write cycles for storing process results or routing on the tag.
Serialized to your scheme
EPCs encoded to your part-numbering or GRAI container scheme and verified before shipment, so line readers never meet a duplicate.
Pilot first
Sample sets in several sizes let your integrator validate read points on the actual line before volume.
Typical automotive tag specification
Process chemicals and temperature windows vary widely between plants. Send your conditions with the inquiry and we confirm suitability honestly before sampling.

Frequently asked questions
Can tags survive paint-shop or e-coat temperatures?
High-temperature paint-shop cycles need specialised tag constructions beyond standard labels and on-metal tags. Give us the exact temperature profile and we tell you honestly whether we can supply a fit, or suggest placing the read point outside that process.
What should we tag first for the fastest payback?
Usually carriers and fixtures: they are finite, reused and metal, so one on-metal tag per asset gives automatic WIP tracking and fixture audits without tagging every component.
Can process data be written to the tag?
Yes, with a user-memory chip: Alien Higgs-9 offers up to 688 bits and Higgs-3 512 bits of user memory. Chips without user memory, such as UCODE 9 or Monza R6, store only the EPC.
Can you match our existing part-numbering scheme?
Yes. We encode EPCs to your scheme (or help you define one), lock memory as required and verify before shipment.
