A method for the at least partially automatic gathering of at least one contacting information item of a telecommunication network user in a telecommunication network by means of a terminal usable in a telecommunication network, wherein the terminal comprises a device for gathering at least one biometric information item of a person, comprising the following process steps: - gathering at least one biometric information item of the telecommunication network user, - sending the gathered biometric information item, together with at least one contacting information item of the telecommunication network user in the telecommunication network to the telecommunication network, - storing the biometric information item and the contacting information item of the telecommunication network user, which have been allocated to each other by the telecommunication network, in a date base, - gathering at least one biometric information item of a person by the terminal, - sending the gathered information item to the telecommunication network, - receiving the message comprising at least one biometric information item of a person from the telecommunication network, - comparing the biometric information item received by means of the message with biometric information of telecommunication network users administrated in at least one data base by means of the telecommunication network, wherein in the data base at least one contacting information item of the telecommunication network user in the telecommunication network is allocated to at least one biometric information item of a telecommunication network user, - sending a message comprising the at least one contacting information item to the terminal which has sent the received message, if the received biometric information item coincides with a biometric information item administrated in the data base, - receiving the message comprising the at least one contacting information item of the person in the telecommunication network by the terminal, and - storing the contacting information item of the person in a telecommunication network received from the telecommunication network by means of the terminal, characterized in that sending the gathered biometric information item, together with at least one contacting information item of the telecommunication network user in the telecommunication network, to the telecommunication network, sending the gathered information item to the telecommunication network, receiving the message comprising at least one biometric information item of a person from the telecommunication network, and receiving the message comprising at least one contacting information item of the person in the telecommunication network by means of the terminal will be realized by means of a message service of the telecommunication network, wherein a short message service, SMS, and/or multimedia message service, MMS, is provided as message service of the telecommunication network, wherein the terminal of a user gathers the biometric information item of another user in that the biometric information item of the other user is gathered by the device for gathering at least one biometric information item of a person of the terminal of the user and the terminal of the user transmits the gathered biometric information item of the other user to the telecommunication network. - gathering at least one biometric information item of the telecommunication network user, - sending the gathered biometric information item, together with at least one contacting information item of the telecommunication network user in the telecommunication network to the telecommunication network, - storing the biometric information item and the contacting information item of the telecommunication network user, which have been allocated to each other by the telecommunication network, in a date base, - gathering at least one biometric information item of a person by the terminal, - sending the gathered information item to the telecommunication network, - receiving the message comprising at least one biometric information item of a person from the telecommunication network, - comparing the biometric information item received by means of the message with biometric information of telecommunication network users administrated in at least one data base by means of the telecommunication network, wherein in the data base at least one contacting information item of the telecommunication network user in the telecommunication network is allocated to at least one biometric information item of a telecommunication network user, - sending a message comprising the at least one contacting information item to the terminal which has sent the received message, if the received biometric information item coincides with a biometric information item administrated in the data base, - receiving the message comprising the at least one contacting information item of the person in the telecommunication network by the terminal, and - storing the contacting information item of the person in a telecommunication network received from the telecommunication network by means of the terminal,
