Vesdo Inc.


Mass serialization and product tracking are based on the individual coding of products, starting if possible at item level. Each single item (product and/or package) gets is own identity through an individual, unique number which is recorded in a secured database, not publicly accessible. For practical reasons this unique number will be encoded in a machine readable form, e.g. as a barcode or RFID (Radio Frequency Identification Device).
These serial numbers can be printed directly on products, packages or serialized labels. A Data Matrix barcode is usually used for coding, often printed directly on the packaging line. Printing barcodes with variable content at high speed is challenging. Vesdo Ltd. has a broad experience in such printing as well as in the corresponding reading technologies. A special focus is placed on the quality assurance of printed barcodes. Special instruments, called barcode verifiers are used to measure the quality level (grades) of barcodes. Barcode quality grades are measured based on ISO standards such as ISO 15415. A minimum quality level is often mandated by law and/or by leading distributors. Vesdo can support you in defining and building up a quality assessment infrastructure. For our own use we deploy the most modern verification and imaging systems as shown on the image below:
If the contraband or diversion of products into gray markets are major concerns, or if authorities ask for a product pedigree, items must be traced along the supply chain to assure the integrity of the distribution network.
A product tracing system will not only provide protection along your supply chain against diversion and counterfeiting. Through the serialized code which is machine readable, automatic access to all variable product data (e.g. expiry date and lot data) on individual item level is possible with the following benefits:

  • Recall of products can be managed in a cost effective manner even in cases where products have been distributed into mixed shipments after picking processes in distribution centers.
  • Automatic identification of manufacturing sites through the tracing system. This allows for easily correlating quality problems to a specific subcontractor or manufacturing site.
  • Providing „First in – first out“ in a stock. This is important for goods with limited shelf life such as pharmaceuticals, batteries and food.
  • Automatic picking process quality monitoring of each picked item. It gives proof of a complete delivery for each individual shipment resulting in fewer claims by customers.
  • Management of slightly modified items. Minor technical modifications of a product or its packaging are often made for tests or validation purpose without changing its article number. The SAP system is not able to handle such items, as no index can be given to the corresponding article numbers. A serial code is extremely beneficial in such a case.
  • Generating marketing data as e.g. “time to market” statistics. Customer sales data at the end of the supply chain is available centrally and “on line”. Moreover, the analysis of marketing campaigns effectiveness can be managed.
  • Reduced stocks. A Track and Trace system allows for permanent wait time analysis along the supply chain. This allows to minimize stocks through integral materials management over the whole supply chain (and not only through individual optimization on each level).
