    • PROBLEM TO BE SOLVED: To prevent an electronic device from responding for saving security reinforcement and electronic device disabling process based on concealment of presence of the electronic device itself. SOLUTION: The electronic device system has at least one pair of an identifier and a validity flag. Identifier information and a 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 shows irresponsive, and consequently, presence of a tag itself can be concealed. The identifier is transmitted by using an identifier control command and if the condition is satisfied, the validity flag is set to show responsive, and after then, operation to the electronic device becomes executable. If the condition is not satisfied, the validity flag is set to show irresponsive, and no response will be made by the electronic device, so that presence of the electronic device itself can be concealed.
