But in my most humble option, I think it would be *very* difficult to obtain an identical sample every time. When it comes to fingerprints the environment probably plays a big role in the sample, for example light conditions, skin moisture, dust on the sensor etc. Maybe there are other people on this list with better insight in this field?
