by a first credential reader associated with a first access-restricted physical resource, receiving, as input to the access control system, a host's initiating access request credential initiating a request to give one or more visitors access right to the first access-restricted physical resource, wherein the first credential reader is arranged in communication with a first resource controller controlling access to the first access-restricted physical resource;
by the first credential reader, receiving, as input to the access control system, a visitor credential for each visitor for which a same access right is requested;
by a second credential reader associated with an access-restricted physical resource and arranged in communication with the first resource controller, receiving, as input to the access control system, a host's finalising access request credential finalising the request to give the one or more visitors access right to the first access-restricted physical resource; and
by the first resource controller, receiving information about the finalisation of the request to give access and the one or more visitor credentials, and allowing a visitor to access the first access-restricted physical resource upon presenting the visitor's visitor credential to the first credential reader.
