Abstract
A field device for automation technology, which has a metal housing for accommodating a field device electronics. On the field device at least one opening is provided, which is closable via a lid composed at least partially of a non-metallic material, wherein an RFID chip and an RF antenna are arranged in the housing in such a manner that communication and energy exchange with an RFID reading device arranged outside of the field device can transpire, and wherein the reading device is so embodied that it provides sufficient energy to the RFID chip when the energy supply to the field device is interrupted, in order to read out via the RFID antenna the data stored on the RFID chip.
