An apparatus includes an energy store for supplying an actuator, an antenna device for receiving, by contactless communication, energy for charging the energy store and one or more control signals comprising a command for triggering the actuator, and a control unit for controlling the supply of energy to the actuator on the basis of the control signals. After the triggering command has been received, the state of charge of the energy store is determined. When this state is less than a state of charge threshold value that is sufficient for triggering the actuator, a response signal to continue contactless communication is transmitted to the transmitting device via the antenna device. When this state is greater than or equal to the state of charge threshold value, the control unit controls the supply of energy from the energy store to the actuator so that it is possible to trigger the actuator.
