Abstract
This technology provides a mechanism to time out communications via relay devices at an appropriate time. [Solution] The mobile terminal device 10 sends an instruction to the printer 20 to generate a variable-expiration-rate device challenge, and the printer 20 generates a variable-expiration-rate device challenge in accordance with the instruction and sends it back to the mobile terminal device 10. The mobile terminal device 10 sends the variable-expiration-rate device challenge and a charge command creation request to the server 30, and the server 30 sends the variable-expiration-rate device challenge and a charge command corresponding to the charge command creation request back to the mobile terminal device 10. The mobile terminal device 10 sends the variable-expiration-rate device challenge and the charge command back to the printer 20, and the printer 20 verifies the variable-expiration-rate device challenge within the expiration period indicated by the variable-expiration-rate device challenge, and if the verification is successful, executes processing according to the charge command.
