Verification versus Validation

Barcode validation and barcode verification are two important factors in ensuring best practice with barcodes, but the two terms are often misunderstood.

Validation versus Verification - a simple definition

Barcode validation refers to the process of ensuring the correct barcode is applied to the correct product.

Barcode verification is the measuring and grading of the quality of a printed barcode to the highest ISO standards.

Why is it important?

With barcoded product often making its way through multiple scanning points along the supply chain, it is not uncommon for disputes to arise between suppliers and customers ovre the quality of printed barcodes. Many companies will impose fines to suppliers who supply them with product that is labelled with poorly printed or unreadable barcodes.

Barcode Validation

Typically, barcode readers are positioned on the production line reading point of sale, GS128 pallet labels. The content of the barcode is transmitted from each scanner to control software such as Logopak`s. This software then compares the barcode data with the factory manufacturing information system.

All Logopak labelling machines are equipped with barcode validation scanners to ensure that any barcode label applied is decodeable and matches the current product. However, as the barcode readers cannot determine barcode quality, they cannot be classed as verifiers.
