PROBLEM TO BE SOLVED: To provide a technique that can use a two-dimensional code in a complicated and advanced manner in an information processing system using a two-dimensional code. SOLUTION: Two-dimensional codes 11 to 14 record sequence specifiers allocated to the respective codes, and instructions determinative of the sequence specifier of the code to be read next to one code. When one code is read by a terminal 20, a control part 24 checks whether the sequence specifier of the code is the same sequence specifier that is determined according to the instruction recorded in another code read just before, and if finding them differing, executes alarm processing. Each code furthermore records various instructions about operational control of the terminal 20, and the control part 24 decodes and executes the instructions. A mere change in the record contents of the codes can thereby change a data processing procedure with the terminal 20. |
