Claims25
A reading apparatus for reading a fingerprint of a finger comprising:
- a photosensor module having a plurality of photosensors arranged in at least one plane;
- a transparent conductive layer provided between the finger and the photosensor module;
- and
- a light source emitting a light incident on the finger,
- wherein said plurality of photosensors read an amount of light from a projection of the finger which contacts the transparent conductive layer, which is more than an amount of light from a recession of the finger which does not contact the transparent conductive layer.
