Nomesque, that sounds like the perfect term: "encryption graphic", thanks. The Taiwanese call it a bar code, even though they know there are no bars in it, like a real bar code. There is no term yet in Chinese for "encryption graphic" I guess. In 5000 years of civilization, the Chinese never came up against such a thing! Thanks for the heads up!
and 2-D bar code, who knew? Thanks, pholy.
