Application for mobile devices that allows users of FirmaDoc BPM to perform the acts of approval or rejection of documents. It constitutes the first mobile version of FirmaDoc, with a scope exclusively in signature-holder mode, but which in future versions will become another perspective to be added to the existing ones of FirmaDoc and FirmaDoc web, as document manager, electronic signature and file tracking electronic devices in mobile devices. It represents a service of great added value, facilitating maximum efficiency in internal management, since it allows eliminating dead times in the document processing circuit of an administrative file for absences or displacements, since the user will have in his pocket the possibility to electronically sign documents anytime, anywhere.
