You will be generated a signed certificate encrypted double key which is associated with a PIN SIGNATURE that you will receive by email after confirming the account.
After receiving the SIGNATURE PIN, you can sign the application form and register all the companies of which you are the legal representative. At the end of completing the document you will need to re-enter the PIN OF SIGNATURE to confirm your identity. The "Save and continue after" button you will find when compiling, will allow you to save in draft the document you can safely complete and sign within 30 days.
You will find a list of all the documents you have compiled, both signed and draft, on the "list of signed documents" page. From this page you will have the opportunity to sign the documents in draft, view and download the signed documents.
