Serialization in the pharmaceutical industry involves assigning a unique digital identity to each medicine pack, typically a 2D barcode encoding product details, batch number, expiration date, and a unique serial number. This data is recorded and tracked throughout the supply chain, providing an auditable trail from manufacturing to patient dispensing. Crucially, this process combats the global threat of counterfeit drugs, enabling ethical manufacturers to ensure patient safety and product integrity. With governments and regulatory bodies worldwide increasingly mandating serialization to secure the drug supply chain.Reliable technology providers offer adaptable systems that help manufacturers implement these complex tracking requirements across diverse packaging lines, ultimately strengthening the fight against fake medicines.
