MobileSign® is software for mobile devices, allowing simple and intuitive signing of e-documents and freely chosen files (e.g. pictures, films, graphics). Our application also offers the possibility to sign PDF (PAdES) documents, with an option of adding e-signature graphical representations. Thanks to the electronic signature, documents get a warranty of the information source’s authenticity and integrity, and they are protected against any unauthorised changes. The possibility to carry out electronic signature verification directly on Android mobile devices, thanks to the WebNotarius service, constitutes yet one more MobileSign® advantage.
