Every day, 150,000 parcels are transported by the French DPD group, which makes nearly 55 million parcels per year. E-commerce is growing the parcel business and, consequently, the transportation volume of parcel service and logistics companies. Online shopping would be unthinkable for the consumers without the speedy delivery of the ordered goods - therefore it is self-evident to keep track of shipments on their way to the consignee, in order to guarantee a correct delivery.
