Abstract:
There is provided a two-dimensional code capable of performing accurate recognition. The two-dimensional code includes: a code data portion (102) where a plurality of square cells (106) are two-dimensionally arranged to constitute code data; and a plurality of corner cells (104) arranged so as to surround the code data portion (102). The corner cells (104) are configured with a greater area than the square cells (106). When the two-dimensional code is imaged by an imaging device, the corner cells (104) can be recognized in a large scale, thereby improving the two-dimensional code read accuracy.
