Abstract
An information code has a positioning layer for coding position information and a data layer for coding arbitrary non-positional data. Both the positioning layer and the data layer may be formed by circularly shifted instances of a window sequence. A product may have information code. Further, the information code may be coded and decoded by using methods for coding and decoding and may be decoded by using an apparatus.
