Abstract: A system and method for communicating personal information of a first user with a second user, without the need for the first user and second user to interact verbally or in any other manner. The first user stores personal information on a server, for example a web server, which is addressable using a URL or other addressing function. The first user causes the network address information to be transmitted in an electromagnetic signal, whereupon it is received by a second user's receiving device and a client of the second user is directed to a network location storing the first user's personal information. The first user's personal information is then displayed to the second user. The system and method of the invention are useful for social networking and other purposes. The transmitted signal may be encoded in Morse code, where differing colors of light represent code elements.
