Visual Watermark is a batch processing application designed to add custom watermarks to thousands of images or videos in seconds. Unlike manual Photoshop actions, Visual Watermark offers a dedicated engine that preserves image quality while overlaying text, logos, or QR codes.

Based on your fragmented topic——it seems you are referring to a software mechanism that uses a visual watermark (e.g., an on-screen graphic, QR code, or steganographic mark) to trigger, validate, or update an activation key via a macro (likely an automated script or VBA macro).
