The invention relates to a method for operating a device (G) comprising a display device (AE), a communication device and a communication system. According to said method, the display device (AE) is activated once a user enters a near field (NB) of the device (G), and the display device (AE) is deactivated once a user leaves the near field (NB) of the device (G). The display device (AE) comprises OLEDs or other components that have a short service life and/or a high power requirement. Activation and/or deactivation are controlled by a transponder (R), e.g. an RFID-TAG to be carried by the user, which responder is detected in the near field of the device. Temporary deactivation of the display device (AE) can prolong the service life of the display device (AE) and/or save power and the use of contactless RFID-TAGs increases ease of operation. The technology can also be used for other purposes, e.g. user authorization. |
