Abstract

See full text

Each black square within a two-dimensional code can be represented by a distribution of spots. Each spot can be made small enough to be invisible to the human eye so that the two-dimensional code can be invisible on or within transparent or nontransparent materials. The spots can be spaced at a large distance to increase the signal-to-noise ratio for an optical code reader. A laser can be used to produce the spots.
