Described is a fingerprinting device with a translucent top layer (8) which forms a finger rest and between which and a light-emitting layer (9) a layer (1) of light-sensitive elements is provided in a matrix arrangement, and with an evaluation circuit (7) connected to the light-sensitive elements. In order to provide advantageous design conditions, it is proposed that the layer (1) of light-sensitive elements have a translucent, photoactive layer (2) based on organic semiconductors between two translucent electrode layers (3, 4) consisting of intersecting strip conductors (5, 6).
