Access control system and a method therein for handling access to an access-restricted physical resource

An access control system for handling access to an access-restricted physical resource, comprising:

• a first credential reader associated with a first access-restricted physical resource, being arranged in communication with a first resource controller controlling access to the first access-restricted physical resource and configured to:
• receive, 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, and to:
• receive, as input to the access control system, a visitor credential for each visitor for which access right is requested;
• and configured to:
• and comprising:
• a second credential reader arranged in communication with the first resource controller, and configured to receive, 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 wherein
• the first resource controller is configured to receive information about the finalisation of the request to give access and the one or more visitor credentials, and to allow a visitor to access the first access-restricted physical resource upon presenting the visitor's visitor credential to the first credential reader.

A non-transitory computer-readable medium having stored thereon computer code instructions adapted to carry out a method for handling access to an access-restricted physical resource, when executed by a device having processing capability the method, performed in an access control system, comprising:

• 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.
