A multi-dimensional bar code comprises one or more colour regions, the one or more colour regions representing encoded data and being arranged to provide light having a parameter value that exceeds a predetermined threshold value. The bar code further comprises one or more identification regions arranged to provide light having a parameter value that does not exceed the predetermined threshold value. The one or more identification regions are distinguished, upon the application of threshold processing, from the one or more colour regions, so that the bar code is identifiable by an apparatus for reading the bar code. An apparatus and method for reading a multi-dimensional bar code, and a method of generating a multi-dimensional bar code are also provided.
