Abstract
Disclosed is an electronic device comprising: a radio module designed to exchange information; an interface device designed to receive a SIM card, the interface device having a data interface, a clock interface, a reset interface and a supply interface designed to supply power to the SIM card; and a circuit board, on which the radio module and the interface device are arranged and electrically connected to one another; characterised in that the radio module has a voltage specification circuit and an associated voltage output, which voltage specification circuit is designed to specify an operating voltage for the SIM card, a fourth electrical connection having a decoupling circuit with power-limited output to the supply interface, which decoupling circuit is designed to decouple the voltage specification and energy supply of the SIM card from one another.
