Solution Spotlight: Inline Barcode Verification


Barcode verification technology confirms the readability of 1D and 2D barcodes to ISO standards to ensure correct identification of the product in the supply chain and at patient point-of-use. Typically, this is done using batch sampling: conducting spot check codes offline, one at a time, using an operator-based handheld or benchtop verifier. Or, worse again, a visual best guess estimation of code quality. The results are then implied to be consistent for the tens of thousands of codes that are not graded, when patently this is not the case.

ISO created standards for readability of barcodes to facilitate modern supply chains where products are identified at high-speed using barcode-reading devices. ISO15416 is the standard for 1D linear codes, ISO15415 is the standard for 2D codes, and ISO29158 is the standard for direct part marked codes. DM475V assigns an overall grade to a code based on measurements of the ISO-defined quality parameters. These parameters measure several factors that affect a barcode reader’s ability to identify and decode a code, maximizing read rates in the supply chain. Lighting is a key element of the conditions that must be met for ISO standard compliance. DM475V uses four-quadrant, 45-degree lighting to conduct verification in complete compliance with the ISO15415/15416/29158 standards.
