You can embed scan lock information in QR code that is printed directly on the document. Copying can be

restricted on devices manufactured by Canon and other companies, if they support the Document Scan Lock

function with QR code.

When using QR code to embed the scan lock information, the tracking information is also embedded

automatically. You can analyze the tracking information to check the data embedded in the QR code,

such as the date, user name, and device name. In addition, the tracking information is updated each

time the document is copied, enabling you to analyze the information for the most recent copy

It is also possible to only embed the tracking information without prohibiting copying.
