Abstract

When persons who meet each other in the business scene exchange their business cards, and business card IDs specific to themselves and send the obtained other person'"'"'s business card ID together with information indicating the situation when the IDs are exchanged, from the cellular phones to register the ID in the business card managing server. The business card managing server includes user'"'"'s own information databases, besides other persons'"'"' information databases. A user who intends to browse another person'"'"'s business card information, sends the user'"'"'s own business card ID and the other person'"'"'s business card ID to the business card managing server from the business card managing client. The business card managing server retrieves necessary information from the other persons'"'"' information database of the user and the user'"'"'s own information database of the other person, and sends retrieved information to the business card managing client as the business card information.
