In this paper we present the new prototype of a portable appliance to be used for logistic operations in production warehouses. It is based on a novel and innovative wireless embedded system able to read products codes; it can also guide users through the different phases of warehouse's everyday life; the system can wirelessly transfer data, service and control/command messages to and from its coupled system server. Retail markets, pharmacies, transport and logistic activities are preferred application environments. From intensive picking to packing, from load of goods from lines to lists and warehouse checks, this system enables the user to work more efficiently and ergonomically.
