Barcode match is also called validation. It is an important variation of barcode quality and has many forms. Barcode match in packaging lines ensures that correct items are going in the carton or pallet. This is the final quality control step in shipment accuracy. Barcode match confirms the right medical device or pharmaceutical items are included in the shipment. And it enhances shipment security. No orphans, no omissions in the package, from shipment, in transit to destination. Orphans and omissions signal an possible adulterated package. Was the shipment infiltrated? Is there a shipper error? Barcode match eliminates errors and helps detect shipment tampering.

Confirming the right item in the right quantity is an important aspect of security: an extra inclusion could be counterfeit. A missing item signals a theft.
