A two-dimensional code encoder for a two-dimensional code which is generated on a mobile phone terminal or a personal computer includes a device configured to generate multiple two-dimensional codes in advance and to store to preserve the two-dimensional codes so generated, a device configured to affix the multiple two-dimensional codes so preserved individually to 12 surfaces of front and rear surfaces of polygonal plates of a three-dimensional polyhedron (a regular hexahedron), a device configured to tag the two-dimensional codes affixed to the 12 surfaces for storage, and a device configured to display the tagged two-dimensional codes two-dimensionally on screens of the mobile phone terminal or the personal computer.

Two-dimensional code encoder

A method for logging in to a system is provided in which a mobile terminal is provided with a function to create a high-density two-dimensional code, access information for accessing an electronic chart system and a time stamp are recorded in the high-density two-dimensional code, the high-density two-dimensional code is deformed, generated and displayed in synchronism with time information of the time stamp, and a high-density two-dimensional code generated by a high-density two-dimensional code authentication read scanner is read, whereby logging in to the electronic chart system becomes possible while taking security into consideration.
