Abstract
An electronic device system has an electronic device including at least one pair of an identifier and a validity flag. Identifier information and condition are registered into the identifier within the electronic device. When an access is made to the electronic device using an ordinary command, no response will be made since the validity flag is “irresponsive”. An identifier is transmitted to the electronic device using an identifier control command and if the condition is satisfied, the validity flag is set to be “responsive”, and thus operation to the electronic device becomes executable hereinafter. If the condition is not satisfied, the validity flag is set to be “irresponsive”, and thus no response will be made by the electronic device.
