Mercosul (Southern Common Market) is a Regional Trade Agreement founded in 1991 between Argentina, Brazil, Paraguay and Uruguay. These countries are keen to foster joint policies in the area of Information and Communications Technology (ICT) and to make it easier for people to communicate and trade across their borders. Hence the Digital Mercosul Project, launched in February 2009 and developed in conjunction with the EU (European Union), financial sponsoring it.Digital Mercosul Project sought to establish a regulatory framework on data protection, electronic invoicing and digital certificates, aiming at providing security and legal validity for the agreements and documents signed in digital form. The ultimate goal was to enable faster and more reliable transactions, in order to improve the production and trade integration and expand the market horizons to small and medium-sized local businesses.
