ELECTROMECHANICAL LOCK

摘要

An electromechanical lock, and its operation method are disclosed. The method comprises: generating (702) electric power from mechanical power by an electric generator; reading (704) data from an external source with the electric power; matching (706) the data against a predetermined criterion with the electric power; powering (708) the electric generator by the electric power; and setting (710) the lock mechanically from a locked state to a mechanically openable state by the electric generator, provided that the data matches the predetermined criterion.
