Define formats, ranges, uniqueness rules and the relationship between visible and digital variables.
How serialised cards
become a controlled series.
Variable marking is only one step. A reliable series requires generation, production, inspection, association and exception control.
Apply marking and access technology within approved visual and dimensional limits.
Inspect readability, correspondence and production status before release.
CONTROL FLOW
One identity through every production step.
The data workflow must be designed with the physical workflow so that rework and rejects do not break correspondence.
Data set
Approved identifiers and expected relationships.
Marking
Serial, QR or Data Matrix applied per unit.
Encoding
NFC data written and locked according to the programme.
Reconciliation
Accepted, rejected and remade units recorded correctly.
Uniqueness must survive exceptions.
A system is credible when duplicates, rejects, remakes and incomplete associations are detected and resolved.
Compare serialisation, QR, NFC and secure identifier architectures.
Resolve substrate, surface, marking and connected construction.
Move from engineering samples to controlled serial production.
A physical identity programme begins with the product, its service journey and the evidence it must carry.
