PROBLEM TO BE SOLVED: To solve the problem that since the contents of a two-dimensional code are not visual confirmation, the notification property of its application, that is, the purpose of its use lacks, and that according as the use of the two-dimensional code becomes variable, it is highly likely to be illegally used. SOLUTION: While recording contents are a two-dimensional code which is visually unrecognizable, information related with the two-dimensional code is noticed by a multiple noticing means in the same region as a region where the code is noticed so as to be visually recognizable. The application of the two-dimensional code, the clarification of its provision origin, and the multiple notation of a safety mark showing that the two-dimensional code is not relevant to any harmful information makes it possible to increase safety, and to give a user a feeling of easiness to handle and a sense of security.
