Abstract
Methods and apparatus utilizing visually distinctive bar code symbols are described. An article is provided with a bar code symbol including a bar code. The bar code comprises a sequence of first and second element types. The bar code symbol is made visually distinctive through one of the following features: a) at least one bar code element is not a single straight line segment; b) a contour of a bounding shape of the smallest area encompassing the bar code has at least two adjacent sides that are not perpendicular; or c) a contour of a bounding shape of the smallest area encompassing an encoding region has no side such that one end of all the bar code elements within the region touches that side. A selectable resolver is used to identify a resource for the encoded value. The resolver may access the resource to provide additional information about the article.
