Abstract
A method is disclosed for creating a 2D barcode. In an embodiment, the method includes: embedding primary information that can be read by a 2D-barcode-reader in a primary information pattern, and embedding secondary information that is made difficult to reproduce without alteration in a visible pattern. In an embodiment, the visible pattern is embedded within the barcode in at least one area that does not contain any primary information.
