Abstract: A composite two-dimensional code according to an embodiment of the present invention is a combination of a first two-dimensional code and a second two-dimensional code. The composite two-dimensional code includes a first cell having a first color, a second cell having a second color, and a third cell having a third color. The first color, the second color, and the third color are different from each other. The first two-dimensional code is acquired by a first filtering processing. The second two-dimensional code is acquired by a second filtering processing.

Abstract: Without using a component such as a chip coil, a winding pattern is formed with a wire with which a main wiring pattern is formed. This enables to deal with the flexibility by realizing a thin product using a coil antenna. Further, the wiring pattern is designed such that the winding pattern is provided and distributed to the main wiring pattern forming a loop, and is formed with the wire so as to have a wound shape small enough compared with the main wiring pattern. In this way, the ratio of the self-inductance to the mutual inductance is appropriately made further large, so that the mutual inductance is made comparatively small.
