ABSTRACT:
A medical device and system is provided with a device housing and with a radio frequency detection device. The radio frequency detection device is functionally connected to an antenna for detecting a radio frequency identification element. The radio frequency detection device has a transmitter and an at least partly electrically conductive shield, which encloses at least the transmitter such that a field generated by the transmitter is effectively shielded towards the outside and the antenna is arranged within the housing and outside the shield.
