The application allows you to select the document to sign and, as it is possible to manage more than one signature, to choose which signature to use and indicate in the document itself where it should be placed. Once the document is signed, the app allows you to share it instantly via email and/or instant messaging, or simply save it.

In addition to signing documents, another of the key features of USign is that users can manage all their signed documents and access them whenever necessary. Not only is it an agile and easy-to-use application, but the management of various signatures and documents is totally secure.
