A notary public frequently uses embossing to mark legal papers, either in the form of an adhesive seal, or using a clamp-like embossing device.
Embossing has been used regularly on postage stamps. Notable early examples include some of the earliest stamps of Italy, Natal, and Switzerland, as well as the early high values of Great Britain. Modern stamps still sometimes use embossing as a design element.Notarizing
