1. A system for handling an at least supposedly partially defective electronic user terminal comprising functionally-relevant circuits and at least one security-relevant circuit located within or connected to the electronic user terminal, wherein the security-relevant circuit is electronically connected to the electronic user terminal, wherein the electronic user terminal, after being successfully identified by a server, is automatically and irreversibly put into an irreparable state by way of an irreversible manipulation of at least one component of the user terminal, if a performed diagnosis of the functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed,the electronic user terminal establishes directly or indirectly a data connection between the user terminal and the server and the security-relevant circuit transmits a unique identifier of the user terminal for the identification thereof to the server, even if a power supply of the electronic user terminal or functionally-relevant circuits of the user terminal fail, and wherein, after receipt of a confirmation to render the user terminal unusable, the server causes the security-relevant circuit of the user terminal to effect the irreversible manipulation of at least one component of the user terminal by sending a control command to the security-relevant circuit to put the user terminal into an irreparable state.
