    Abstract: A method for controlling access of a user to a physical device which is provided with an access control unit that can block and release access to functions of the physical device includes the provision of a central control platform and a mobile access device. An identification check of the user is carried out, the user being identified by the mobile access device. Following a successful identification check, a wireless communication link is established between the mobile access device and the access control unit of the physical device. Identification information and unique access data are transmitted from the mobile access device to the access control unit. The access control unit ascertains the access rights of the user to the physical device using the received information and additional information from the central control platform.
