1. A two-dimensional code formed on a medium, comprising:
a first code wherein a plurality of cells are arranged in a predetermined array shape and data is defined by two or more colors of the plurality of cells distinguishable from one another, and
at least one of the following first to third aspects:
(A) a first aspect wherein the two-dimensional code further comprises a second code formed by a predetermined rule different from that of the first code, each of the plurality of cells has a predetermined area, the second code is defined in special cells which form at least some of the plurality of cells, at least some of the special cells have an area excluding the said predetermined area, data of the second code is defined by identifiable marks disposed at predetermined positions in the said area excluding the said predetermined area, and an arrangement position of the said mark is set in any one of areas formed by dividing at least an area excluding the said predetermined area of the said special cells into arbitrary shapes;
(B) a second aspect wherein the two-dimensional code further comprises a second code formed by a predetermined rule different from the first code, the second code is biometric information, and the biometric information is obtained by encoding at least one of the following (1) to (3):
(1) an image photographed with a first image input unit mounted or connected to a two-dimensional code generation apparatus;
(2) an image stored in advance in the two-dimensional code generation apparatus; and
(3) information obtained by a predetermined method from the photographed image or the image stored in advance; and
(C) a third aspect wherein coordinate values of each of the plurality of cells of the first code-defining an arrangement of each of the cells are identifiable from at least a part of the predetermined array shape, at least one of the plurality of cells is a reference cell which is formed with a reference predetermined area including a reference point and one or more first surrounding areas arranged at least at a part around the reference predetermined area, the first surrounding areas are distinguishable from the reference predetermined area, and coordinate values of the reference point can be calculated.
