Abstract
A circuit () comprises a first circuit point () and a second circuit point (), which first circuit point () and second circuit point () are designed to be connected with RF transmission means () being designed for receiving in a contact-less manner a carrier signal (CS) from a read/write station and for feeding the circuit () with the received carrier signal (CS). The circuit () further comprises circuit testing means () being designed to carry out functional tests of the circuit () and to output a modulated response signal (TS-MOD) via the first and second circuit points () only if the functional tests have been successful. The circuit () further comprises test trigger signal detecting means () being designed for detecting a test trigger signal (TS) that is applied across the first circuit point () and the second circuit point (), wherein the test trigger signal detecting means () are designed to trigger the circuit testing means () to carry out the functional tests if they detect the test trigger signal (TS).
