SigningHub enables you to add a QR Code to documents to help simplify signature verification. The QR code in the document enables users to scan the QR code with the camera on their smartphone. Upon scanning the user is redirected to a page which allows viewing the document in read-only mode and viewing the verification results for the digital signatures, separately.

This field is associated with a specific document and becomes the part of a PDF document when it is shared, signed, reviewed or updated. The availability of a QR Code field is subject to your assigned enterprise user role. If you wish to use this feature, ask your Enterprise Admin to enable the QR Code option in your Role>Document Settings. SigningHub embeds annotations, and other necessary content within a PDF file to make your documents fully compliant with the PDF/A-1a and PDF/A-1b standards. This content embedding is required by ISO 19005-1, and is usually associated with a document's visual appearance.

However. you can also manually drag the field for moving it to the desired position on the document, and the coordinates will be updated accordingly. These coordinates are only available as far as the status of a document is Draft.
