Abstract: A method is provided using a safety system. The safety system has an electronic access system for a safety zone for objects, at least one radio transponder and at least one radio station to recognize the radio transponder, at least one control and evaluation unit that is connected to the radio station for evaluating the read radio transponder information, and at least one spatially bounded access zone having an access station. The safety zone is only accessible via the access zone so that the access zone can be passed through by the object before reaching the safety zone and after leaving the safety zone, with the access station being actuated when an object passes through the access zone. Permitted objects have the radio transponder, with the radio transponder having an identification whereby the object can be identified. The permitted objects having the radio transponder can pass through the access zone.
