A barcode verifier is a device used to grade the quality of printed barcodes according to international standards (like ISO/IEC 15415, 15416, and 15426). Unlike barcode readers that simply decode the barcode, verifiers analyze, grade, and ensure that barcodes meet compliance standards for reliability in scanning across supply chains.
Cognex is a global leader in machine vision and industrial barcode reading. Their verifiers are known for precision, ease of use, and compliance with all major global standards.
