<p>A data carrier (1) which can be operated in a contact-bound mode and in a contactless mode and a circuit (1A) for such a data carrier (1) has a supply voltage generating means (35) for deriving a supply voltage (VDD) for various circuit sections of the data carrier (1) and of the circuit (1A) from a received useful HF signal (HF), and additional switching means (91) by means of which the application of a potential (VDD), which appears as a result of the supply voltage generated by the supply voltage generating means (35) to at least one contact terminal (17A) can be inhibited.</p> |
