Abstract: The present invention discloses a method for obtaining information provided by contacts via network after inputting contact information. The method includes the following steps: step A, user A obtains user B's contact information; step B, user A inputs user B's contact information to address book; step C, user A sends inquiry request to a contact information server according to user B's contact information; step D, according to the contact information submitted by user A, the contact information server searches the information stored in the server to find out whether there is some information from user B related to the contact information. If yes, it returns the related information to user A, else, it informs user A that there is no related information. This invention breaks out the limit that the name card can only transfer information with limited number of words and limited size of images, and it expands the amount of information carried by the name card and the expression forms of information.
