A method of wirelessly accessing services of a server computer by a mobile communication device. The method comprises receiving a short-range radio beacon signal associated with a server computer, sending a request for information about services provided by the server computer associated with the beacon to a service registry via a long-range wireless communication link. The method further comprises, in response to receiving information about the services provided by the server computer, connecting to the server computer, accessing a service provided by the server computer. The method further comprises receiving a second beacon signal, determining that the second beacon's identity is not identified in the white list, and, in response to determining that the second beacon identity is not white listed, not attempting to access a second server computer associated with the second beacon.
