Signing a PDF File using a Certum e-Signature with card and reader (QES)

1. On the CertumSign platform, you can easily and quickly sign an uploaded or received PDF document. You can choose between:
   • a qualified electronic signature on a Certum cryptographic card
     
2. Before signing, make sure that:
   • You have connected your card and reader to your computer
   • You have the proCertum CardManager software or software provided by another supplier
   • The qualified certificate is registered on your device
3. Log in to your CertumSign account at sign.certum.pl and select the document to sign. A window displaying the document’s content will appear
   
4. In the Signature Method section (on the right side), you will see the name of the selected e-signature method.  In the case of a card signature, it is a Card/Certificate. If you want to switch to a card signature, click Change. From the list select I have an electronic signature kit.
5. Click Sign. You can choose a location within the document to visualize the signature
   
6. On the next screen, you will see a message about launching the Certum Sign Service application. If you do not have Certum Sign Service yet:
   • Download the Certum Sign Service application for Windows
   • Download the Certum Sign Service application for macOS

   

7. A pop-up window will appear in your browser. Allow the startup/creation of Certum SignService:
   • In Google Chrome it is the Open Certum SignService button.
   • In Safari it is the Allow button
8. Then a list of certificates will appear. If the certificate with which you want to sign the document is not selected, click its name, then a drop-down list will appear with other certificates registered in the device’s certificate store.
   In the qualified certificate information, you will see:
   • full name;
   • certificate number;
   • expiry date;
   • certificate status.
   • To proceed with the signing, select – Confirm
     
9. Enter the PIN assigned when installing the certificate. If the code is correct, you will receive a message that the file has been signed. Done!
