Abstract
The invention relates to a sheet-shaped value document, such as a bank note. An authenticity feature which can be reliably verified by machine or by humans and which can moreover not be deceptively imitated by copying technology is realized by an electro-optical and/or acoustic display device integrated in the value document.

17. An apparatus (10) for processing sheet-shaped value documents (1, 1′
- , 1″
) with an integrated display device (5, 5′
, 17) which displays an information content optically, acoustically, or a combination thereof, which comprises at least one of a writing device (12, 15) for writing data to a data memory (4) of the value document to permit a display state of the display device to be changed by changing a data content of the memory, and a sensor device (33) which, for determining the authenticity of the value documents (1, 1′
, 1″
), measures the information contents thereof displayed optically or acoustically by the display device (12, 15) and compares the thus measured signals with predefined reference values corresponding to authentic value documents (1, 1′
, 1″
). - View Dependent Claims (18, 19, 20, 21, 26)
