Haven’t these advancements finally rendered barcode verification an expensive and redundant waste? Consider a current case history. Company XYZ (name changed to protect identity) distributes clothing using offshore contract manufacturers. They utilize…

DPM Barcode Verification

Direct Part Mark or DPM barcodes pose a special set of challenges for verification.
