FIELD: information technology.
SUBSTANCE: device (1) includes a light source (14, 51, 52, 68) for exciting luminescent radiation and a luminescence sensor (12) for detecting luminescent radiation from the valuable document (BN) with spectral resolution; the light source (14, 51, 52, 68) creates an illuminated section (35) on the valuable document (BN) being transported past the luminescence sensor (12) in the direction (T) of transportation, said section being stretched in the direction (T) of transportation, and the luminescence sensor (12) has a detector unit (21) designed to measure luminescent radiation with spectral resolution, and a detector unit (27) designed to measure luminescent radiation without spectral resolution.
EFFECT: high quality of verification by enlarging the verification section in case of weak luminescence.
