There is disclosed a secure media device 300. The secure media device comprises a display 110, a memory 302 and a processor 301. The display is used for displaying a presentation. The memory is used to store a representation of the presentation, example in digital form. Upon initiation by, for example, a pushbutton 112, the processor causes the presentation to be displayed on the display. The secure media device may also comprise a loudspeaker 321. By "secure", it is meant that the contents of the memory may not readily be read by unauthorised personnel. The memory may be integrated with the processor as a single integrated circuit or may be mounted to a printed circuit board. Alternatively, the media device may include an enclosure for preventing unauthorised personnel gaining access to the memory. |
