Implementation and Use

To use the OZ Verifier solution, there are primarily five key steps:

a. Add the “verification QR code” component to the form in the designer.

b. Print the form through the HTML5 viewer (either from the server or the scheduler). The viewer used in the OZ server must be the Java viewer. The QR code added in the designer is then printed on the paper document.

c. Install the OZ Verifier application in your device.

d. Scanning the QR code on the printed paper document with the OZ Verifier app opens the original document (PDF) stored on the server.

e. Verify whether the content of the original document (PDF) matches that of the printed paper document.

NOTE: Our solution handles everything up to step 4, while step 5 is the user's responsibility.

A point to be aware of is that OZ Verifier only verifies when a paper document was issued by a specific organization and ensures that the original PDF was not tampered with during transmission. It does not verify whether the content of the printed document matches the original PDF file.

In other words, users must manually compare the content of the printed document with the original PDF displayed in the app to ensure they match.
