Abstract
The invention relates to a method and a sensor for checking a value document which is moved relative to the sensor. The sensor is arranged to detect the luminescence of the value document in two different spectral regions at the same location of detection simultaneously. The two temporal intensity patterns of the first and second luminescences detected in different spectral regions are evaluated relative to each other. This eliminates the motion effects which distort the two intensity patterns in the same or at least very similar manner.
