We present a novel and innovative wireless embedded system for logistic applications: it is a prototype of a portable appliance to manage operations in production activity. The system is based on a wearable device which is able to read products codes and allows the system to guide users through the different phases of warehouse's everyday life; by means of IEEE 802.15.4 standard – on the ISM 2.4 GHz band – the system can wirelessly transfer data, service and control messages and commands to and from its coupled management server. The system is addressed to retail markets, pharmacies, porterage and logistic activities and it allows the user to work more efficiently and with a mobile terminal that is more ergonomic: from intensive picking to packing, from load of goods from lines to lists and warehouse checks.
