A service providing apparatus has a first communication unit, a connection
information generator, an existence detector, an existence confirmation
request receiver, a connection information transmitter, an authentication
unit, and a service providing unit. The second communication unit
performs wireless communication with the service receiver located in a
second wireless area narrower than a first wireless area. The existence
confirmation request receiver receives the existence confirmation request
signal transmitted by the service receiver through the second
communication unit when the service receiver detects to be within a
prescribed distance. The service providing unit connects with the service
receiver authenticated by the authentication unit, and provides services
to the service receiver through the first communication unit.
