IDENTIFICATION & INDUSTRIAL MARKING
3D barcode
“3D barcode” is a context-dependent term often used for markings formed in or on a surface, including raised or recessed codes. Specify the actual symbol and marking method before selecting equipment.
3D BARCODE IN PRACTICE
- Specify the markingName the symbol, material and marking process.
- Test the readerTrial the real part under working conditions.
- Confirm traceabilityLink the decoded identity to the correct record.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Permanent mark. Same identifier.
A reusable metal tool has a Data Matrix mark applied directly to its surface instead of an adhesive label. A reader captures its serial identity when it enters and leaves a service area. Calling this a “3D barcode” does not tell the buyer which reader or verification settings to use. The specification must identify the 2D symbol, marking process and material, with a successful read demonstrated on a production sample.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
Put this term to work. Use the 3PL selection guide to turn these operating requirements into provider checks, and the 3PL RFP guide to document evidence, responsibilities and exceptions.
A LITTLE MORE CONTEXT
Questions about 3D barcode
Is 3D barcode a single standard format?
No. Ask what the supplier means and request the precise symbology and marking specification.
Is direct part marking always three-dimensional?
No. A code may be printed or otherwise marked directly onto an item without encoding data in depth.
Will any 2D imager read a marked part?
Not necessarily. Reader capability, optics and lighting must suit the marking and surface.
