# OZ Verifier Introduction

OZ Verifier is a document authentication verifier provided by Forcs.

It allows you to check whether a document issued and printed by an institution has been tampered with and also lets you verify the original document through the app.

By simply scanning the QR code on a printed document using the app available on Android and iOS, you can quickly and easily verify the authenticity of the document. 

When you print a form that includes the "verification QR code" component via the HTML5 Viewer from the server (or from the scheduler), the verification QR code is printed with the paper document, containing information to check the original document.

The original document (PDF file) stored on the server does not include the QR code. The QR code is only printed on the physical paper document.
