ABSTRACT:
In a game system including a wireless LAN AP instrument and a portable game device, the AP instrument transmits a beacon signal including a MAC address of the AP instrument and a network ID obtained by encoding an instruction code so that the network ID can be decoded using the MAC address. The portable game device decodes the network ID included in the received beacon signal using the MAC address, and executes control based on control data when authenticity determination data included in the decoded instruction code coincides with specific data and the present date is within a valid period indicated by valid period data.
