DIGI SENS created with e-nventory a system that makes a complete and constant control of the stock possible. E-nventory is build around a family of scales with integrated ID-System of various sizes and maximum loads for continuous determination in real-time of the quantities of all stock items. The information on stock status (e.g. the number of parts) and storage location are transmitted via a bus to a central processor, which in turns sends them to the Internet. The stock status data can thus be accessed by external work-stations (suppliers, logistic firms, customers, etc.). The stock data can be both integrated into the existing stock management software and used separately in parallel.
