Abstract
A method for granting access to restricted areas such as computers, doors, vehicles, or other areas to which access by a user is controlled. An access code is transmitted from a central computer via radio waves to a user's radio terminal, such as a mobile telephone. The radio terminal transmits the access code over a short-range radio link to a communication device at the restricted area. The communication device transmits the access code to the central computer, which compares the received code with the code that the computer transmitted to the radio terminal to determine whether access should be granted.
