Abstract: A user device transmits a location update message, indicating a location of the user device, to a network server. Responsive to the location update message, the user device receives from the network server a list of radio frequency beacons transmitted by resource devices and associated service identifiers for services available from the resource devices. A radio frequency beacon received from a resource device is identified as being in the list. A message is sent to the resource device requesting access to a service identified by a service identifier in the list associated with the radio frequency beacon and providing credentials for a user of the user device in the message.
