Physical access control system initially developed by La Poste, the French National post office, to enable professionals to access communal parts of buildings. These professionals include operators and service providers from the post office, Enedis (electricity), GrDF (French gas), press deliverers, lift operators, plumbers, electricians, cleaning companies, etc.
Those permitted to enter are equipped with a key. 2 types of keys exist:
- resident key: each resident is registered by the controller and has permanent access
- service provider key: the service code or public key is registered by the controller and time slots can be configured
