To provide a control unit for entrance and exit, which makes it unnecessary to request a central control system to transmit biological information via a network each time personal authentication is performed at the entrance and exit, which can achieve the management of the entrance and exit even on the occurrence of failures in the network, which eliminates the risk of leaking a user's individual biological information, stored inside biometric authentication equipment, to the outside, and which can achieve high security; and to provide a management system for the entrance and exit using the control unit.

Biological information authentication equipment 3 compares and collates the read individual biological information 14B with registered biological information 16B transmitted from a control section 15, and rapidly erases the read individual biological information 14B and the registered biological information 16B, transmitted from the control section 15, from the inside of the biological information authentication equipment 3, after the completion of collation processing. The result of the collation is transmitted to the control section 15. When the read individual biological information 14B agrees with the registered biological information 16B, the control section 15 controls a locking/unlocking section 7 and unlocks a door 5, so that the user can get into the room 4. In this case, the control section 15 makes the user's history of the entrance into the room stored as information 16C on the history of the entrance and exit in a storage section 16.
