All QR code images that are generated by this extension will be stored in the user asset folders, typically \Assets\UserFiles{UserName}\Images\GeneratedAssets. This area can be cleaned regularly by other processes outside of the scope of this extension. As a result of such cleaning process, the generated QR code images might be removed.
No known limitations at present.
