A system and method are described for controlling and monitoring access to restricted areas, such as mass transportation means (underground trains, trains, airports, ships and the like), commercial buildings, schools, factories, data centres and other locations with circulation of people, provided with a processing unit (10) which receives information from an authentication unit (20) and actuates one or more bars (31) of light-emitting elements that form limiting barriers (30) for a lock area (GA), assigning to each user category (authorised (AU), non-authorised (UU) or special (SU)) respective indication windows (311, 312 or 313) which follow the movement of the user through the lock area (GA), making it easier for security agents to identify visually and possibly approach non-authorised users (UU) and to allow authorised users (AU) and special users (SU) access to the restricted area (RA). |
