Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A two-dimensional symbol comprising:
first modules that are arranged vertically and horizontally in a matrix such that centers of at least three or more first modules of the first modules that are arranged vertically are spaced apart at a first interval and centers of the at least three or more first modules of the first modules that are arranged horizontally are spaced apart at a second interval; and
second modules different from the first modules,
wherein the two-dimensional symbol comprises:
a finder pattern comprising a first set of the first modules that are contiguously arranged in horizontal and vertical directions to allow a symbol position to be detected using a coloration pattern of the first set of the first modules;
a timing pattern comprising a second set of the first modules to specify a center position of the first modules using a coloration pattern of the second set of the first modules;
a first recording area comprising a third set of the first modules to record first data, using a coloration pattern of the third set of the first modules; and
a second recording area comprising the second modules to record second data using a coloration pattern of the second modules,

wherein a size of one first module of the first modules in the finder pattern is larger than a size of one first module of the first modules in at least a part of an area of the two-dimensional symbol,
wherein the part of the area is different from the finder patten in the two-dimensional symbol, and
wherein one second module of the second modules in at least the part of the area is arranged in a portion that does not overlap the first modules and that includes an intermediate point between two adjacent first modules of the first modules in at least the part of the area.
