Abstract

A system for wireless communications includes multiple portable digital devices which automatically and selectively communicate with each other. Each portable digital device has a proximity transceiver and an electronic memory which stores the user'"'"'s and listing of matched identification codes which represents all compatible PDD users. During operation, the portable digital devices communicate with each other by transmitting identification codes and receiving identification codes. The PDD compares the received identification code to the listing of matched identification codes to determine if there is a match. If the received identification code is on the listing of matched identification codes, a match is detected the match indicators of the PDDs are actuated to inform the users that a match has been detected.
