TraSer, developed by researchers in Hungary, Romania, the Netherlands and Finland, is a track-and-trace open source program that enables small companies to share commercially sensitive information and monitor the movement of materials and products from suppliers to customers. TraSer also allows companies along the supply chain to share data, instead of having the information owned or controlled by a central authority. The program creates a unique product identifier by combining a product identification code with a company Web address, which does not depend on registration with a centralized authority. “TraSer is designed as an entry-level solution platform,” says Elisabeth Ilie-Zudor, coordinator of the TraSer project and a researcher at the Computer and Automation Research Institute of the Hungarian Academy of Sciences. “We strove to keep it as simple as possible in operation. Still, it remains vital to understand what is actually done in a track-and-trace network to make it work.” By eliminating the need for a centralized service, the network is less vulnerable to malfunction or abuse. A TraSer network has a core of connected company servers, surrounded by an ‘envelope’ of clients. Those clients can access information from bar codes, radio frequency identification tags, or other carriers of a product’s unique identifier. TraSer also can adapt to a wide range of input types because the interface between client and server is uniform. Ilie-Zudor says that “companies need to view shared data as an investment where the creation of a better picture for everyone leads to a payback in cost reductions, better working methods, and greater coordination.”
