Recording of information

摘要

A product intended to be used in connection with the recording of information is provided. The product has a surface in which there are a plurality of different information alternatives, each having an associated code area. The surface is provided with a two-dimensional position code which codes coordinates for a plurality of positions on the surface in the code areas. The position code is unrelated to the information to be recorded. The surface permits recording of a desired information alternative by reading the position code for a position in the code area associated with the desired information alternative.
