After you download the application, you will need to create a signature using the built-in tools. The tools allow you to build a proof that the documents are signed by a real person. The signature creation is easy because you only need to fill some forms with your name, birth date, contact number, handwritten signature, etc. Once you complete this, it will be sent for approval using secure online servers. After the process completes, you can then attach the signature to documents and practically all the formats the program supports.
