Businesses may offer their services not only through internet websites but also by short-range wireless portals ( 51 A,B,C) intended to catch passers-by; indeed, this latter means of business promotion may be used instead of an internet site. A method is provided of gathering information from such portals ( 51 A,B,C) for use in a database service system 40 . More particularly, a mobile device ( 20 ) provided with a short-range wireless receiver ( 21 ) is moved within range of such a portal and collects information about the services available from the local entity operating the portal. The device ( 20 ) then uses a cellular radio network ( 10 ) to send this information, together with location data about the portal, to a remote database service system ( 40 ) holding similar information from other portals. The user of the mobile device can be credited with a reward by the database service system for collecting such information.
