Founded in 1957, TAO employs over 500 people to provide trucking services all across Mexico, with connections into the United States and Canada. It also employs 4D to control the operations of its three companies (TAO, Firsa and Triple A) via VPNs situated throughout Mexico, in conjunction with advanced equipment and satellite monitoring. Their web site allows customers to track the exact location of their goods, available online with minimal delay. Today TAO, Firsa and Triple A are further using 4D-based applications to manage their general information systems as well.
