Earth-leakage circuit breaker with automatic monitoring capability

Identification card, including a card body, an integrated semiconductor circuit being mechanically inserted and protected in the card body for storing data to be read-out and read-in in changed form, a receiving antenna device, a rectifier circuit connected to the receiving antenna device, a filter circuit connected between the rectifier circuit and the integrated semiconductor circuit. The rectifier and filter circuits generate a supply voltage for the integrated semiconductor circuit from an energy field, a microwave transmitting antenna connected to the integrated semiconductor circuit, and a transmitter connected to the transmitting antenna.
