Abstract

A system for exchanging data includes at least two memory units, each unit functioning as both a transmitter and a receiver of data. The exchange of data occurs whenever at least two memory units are within a certain distance of each other. The user is thus capable of simultaneously being both a transmitter and a receiver of data, such that the transmitter can send data continuously but can receive data transmitted from other memory units only when the receiver is within a certain distance from a transmitter. As a result, data are received only by those memory units that are located in the immediate environment of the transmitter. Since the data transmitted can be selected personally by the user, the data thus reflects the preferences of the user acting as the transmitter.
