Metal barcode systems can be widely applied in automatic control, detection, and automated management, such as registration, toll collection, and anti-theft for vehicles, cars, motorcycles, bicycles, etc.; for mechanical products, electronic products, medical devices,management systems for weapons, ammunition, and military warehouses; for confidential registration and management of important certificates and credit cards. In the field of anti-counterfeiting, due to the unique equipment and complex processes involved in manufacturing metal barcodes, they are difficult to forge or replicate. Additionally, this technology is protected by patent monopoly, making it less prone to leakage. Metal barcodes can be customized with varying internal information according to user needs, assigning different content to each metal barcode label, which is impossible to decipher. By affixing metal barcode labels to the surface of objects, in anti-counterfeiting efforts, not only can counterfeit products lacking metal barcodes be visually distinguished, but internal information can also be verified through automatic identification technology, enabling both law enforcement and consumers to easily identify counterfeit and inferior products.
