Abstract
An interpersonal-introduction signalling system includes a receiving and transmitting transceiver having a relatively short range response and of such size as to permit convenient carrying by a person. A code system defines a plurality of categories, each of which has a particularly identifiable characteristic. Each person carrying a similar receiving and transmitting transceiver can select a particular code to send and a particular code to accept, such that designated information is transmitted and/or received. When accepting a signal or information, a different signal is sent by the receiver to indicate the acceptance to the person transmitting. The transceiver includes an indicator to alert the receiving person and indicate the necessity of transmitting a response. Thus, the encoding permits the several persons involved to define the different categories of persons having selected unique characteristics for contact.
