Communication set-up for wireless communication and method for controlling such a communication set-up

A method for controlling a communication set-up, the method comprising:

• a) providing the communication set-up, the communication setup including an electronic circuit, the circuit including at least one communication unit configured for wireless communication, the communication unit including an antenna network connected to an antenna, and an actuating unit, wherein the circuit further includes a signal processing unit, and in response to operation of the actuating unit, the actuating unit is configured to release a signal to the signal processing unit, which, on the basis of the released signal, converts the communication set-up from a blocked state to an enabled state, or from the enabled state to the blocked state;
• b) operating the actuating unit;
• and
• c) converting the communication set-up from the blocked state to the enabled state, or from the enabled state to the blocked state;
• wherein the communication set-up is attached to a card, the card being configured to wirelessly and contactlessly receive energy to power the card from a device external to and separate from the card by an electromagnetic field emitted by the device.
