To surely grasp history information (such as a passer himself, a borrower name, and a borrowing reason) of the passer while passing a borrower without new registration.
This authenticating device 20a imparts authenticating information of one's own and borrowing information (including information such as a borrower, a borrowing period, and the borrowing reason) for indicating a borrowing period for indicating how long the authenticating information can be used, to the other authenticating device 20b, as an electronic duplicate key for authentication. The remote device 30 unlocks the doorway when possessing the electronic duplicate key in the borrowing period even when permission registering information of the authenticating device 20b is "nonpermission", and holds the effect of "possessing the electronic duplicate key" in addition to the effect of "the passing" to a passing history.
