An invention relates to a device enabling face-to-face contacts between
persons immediately or almost immediately when their profiles match, i.e.
when the persons have similar requirements or interests. The device may
be an accessory of a mobile phone and it comprises a power source such as
a battery or an accumulator. The device further comprises a first radio
and a second radio that use different types of wireless short-range radio
technologies. The first radio is configured to communicate with a
terminal of a mobile communication network by receiving content for a
profile of a user. This profile relates to a certain contact service and
the content of the profile is created by means of the terminal. The
second radio is configured to communicate with another device by
transmitting the profile from the device to the other device. The second
radio is further configured to communicate by receiving a message of the
contact service when the transmitted profile matches with a profile of
another user. In addition to the device, the invention optionally
comprises a network of above-described devices.
