IDENTIFICATION & TRACEABILITY
2D barcode
A 2D barcode encodes information across two dimensions in a machine-readable pattern. The symbol type and data format determine what it can carry and how a receiving system interprets it.
2D BARCODE IN PRACTICE
- Choose the dataIdentify the product and traceability fields needed.
- Read the symbolUse compatible imaging equipment and software.
- Validate the recordCheck identity, unit, lot and destination fields.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
One scan. Several fields.
A receiving team needs to capture a product identifier, lot L2401 and expiry date from one carton. A suitable 2D symbol can encode the required data together. The receiver still checks that the identifier belongs to the carton packaging level and that the WMS maps lot and expiry into their own fields. A code that scans into one unparsed text field has not completed the receiving task.
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 2D barcode
Is every 2D barcode a QR code?
No. QR Code, Data Matrix and other 2D symbologies have different structures and uses.
Does a 2D barcode need the internet?
Decoding the symbol may not. Opening a linked page or looking up an inventory record can require a connection.
Can an old laser scanner read it?
A laser-only 1D scanner generally cannot read a matrix 2D symbol. Confirm compatibility with the actual hardware and software.
