Verification and Validation Barcode validation and barcode verification are two important factors in ensuring best practice with barcodes, but the two terms are often misunderstood. Validation vs. 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 standard. 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 over 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 such as Erwin Sick’s CLV410 are positioned on the production line reading point of sale, TUC and GS128 pallet labels. The contents of the barcode is transmitted from each scanner to control software such as Logopak’s Ivalidate. This software then compares the barcode data with the production data downloaded from 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. Vericoder - the integrated verifier from Logopak makes manual verification checks a thing of the past.
