The invention relates to a method for activating a portable data carrier () in which a first portable data carrier () is supplied in an inactive state to a user, after the user has requested the first data carrier () with the aid of a second portable data carrier () from a central instance, whereby the first and the second data carrier () have access to authentication data for mutual authentication. In the method according to the invention a communication connection is set up between the first and the second data carrier (), via which the first and the second data carrier () mutually authenticate each other on the basis of the authentication data and establish a cryptographically secured end-to-end connection. Via this end-to-end connection then the second data carrier () activates the first data carrier () by transmitting activation data to the first data carrier ().
