Draft answers. To confirm with product and engineering.
How is a stamp different from a QR code?
A QR code points every reader to the same place. A stamp is branded, unique per document, and checked: it opens only for the person and the time a grant allows.
What does the reader need?
A phone camera. [App or browser: to confirm with product.]

How is it licensed?
