PROBLEM TO BE SOLVED: To obtain an information code which can easily specify information represented as a two-dimensional code if the two-dimensional code can not be read by providing auxiliary information which can specify main information represented as a two-dimensional code and can be read by a machine. SOLUTION: Two two-dimensional codes 11 and 12 are printed in a right lower area G on a slip. The two-dimensional code 11 represents the main information comprising a predetermined information and the two-dimensional code 12, represents the auxiliary information which can specify the main information. If the main two-dimensional code 11 can not be read owing to disfeaturement etc., the auxiliary two-dimensional code 12 corresponding to the main two-dimensional code 11 is read by a reader to input a slip number. Consequently, the main information is specified according to the slip number as the auxiliary information inputted from the reader. Consequently, the main information represented as the main two-dimensional code 11 can easily be specified. |
