What is it for?

The service is used to customize documents such as: laboratory reports, prescriptions, reports, opinions, diplomas, policies, certificates, in short, any document that is in PDF format. In addition, the PDF documents, signed with the electronic seal, follow the rules and determinations of ANS, ANVISA and other federal and state agencies that require a digital signature, as well as the signatory's registration number in their respective control body.

How does it work?

  2. When uploading the document, the option of digital signature in PDF with the Electronic Seal must be selected.
  3. When signing, the QualiSign portal will apply the image to the document as associated with the signer's profile.
