PROBLEM TO BE SOLVED: To provide a technology for improving security against unauthorized use of an optical reading code copied by copying or the like.;SOLUTION: Short-distance wireless communication units 12a and 12b receive (acquire) auxiliary information updated at an appropriate timing. Reading units 11a and 11b optically read the information indicated by a two-dimensional barcode that is covered by a reading area. A determination unit 10a compares the auxiliary information acquired by the short distance wireless communication units 12a and 12b with the auxiliary information included in the information read from an optical reading code by the reading units 11a and 11b to determine if the optical reading code is adequate.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
