Abstract

In a method of releasing communication between at least two communication devices (4, 5, 6, 7, 8), a data carrier (36), that is able to be read from in a non-contacting manner and that contains an authorization code (AUC), is brought into the vicinity of communication devices (4, 5, 8) that are to be released, and the authorization code (AUC) is read out in a non-contacting manner by a reading device (21, 22, 25) contained in the relevant communication device (4, 5, 8) and is fed by the reading device (21, 22, 25) to a releasing device (40, 41, 44) that, after analyzing the authorization code (AUC), is responsible for releasing communication between the communication devices (4, 5, 8) to be released.
