To be able to sign a PDF document it is necessary to have a digital certificate installed on your computer, such as the idCAT Certificate. Remember that the idCAT Mobile is not a digital certificate.

1. Go to “All Tools” and select “Use a certificate”

2. Select “Sign digitally” and accept the dialog box


3. Select the space where you want to insert the signature, dragging the mouse around the document.
