Method for checking a document of value guided past a checking sensor in a transport direction, wherein a luminescence feature is present distributed substantially homogeneously in or on a security region extending in the transport direction over the document of value and has a sampling sequence repeating multiple times as the document of value is guided past the checking sensor, the method comprising the steps of: - irradiating a checking region of the checking sensor which at least partially overlaps the security region with excitation radiation and checking radiation in a first irradiation phase, wherein the checking radiation is designed to be at least partially remitted by the document of value in a detection spectral range of the checking sensor, and the excitation radiation is designed to bring about emission radiation of the luminescence feature in the detection spectral range; - sampling at least one spatially dependent remission spectral value in the checking region in the first irradiation phase; - irradiating the checking region only with the excitation radiation in a second irradiation phase; - sampling at least one spatially dependent emission spectral value in the checking region after the first irradiation phase; and - performing an authenticity check according to which the document of value is classified as being genuine or not genuine on the basis of the at least one spatially dependent remission spectral value, which has been sampled multiple times in a spatially resolved manner, and of the at least one spatially dependent emission spectral value, which has been sampled multiple times in a spatially resolved manner, wherein the sampling of the at least one remission spectral value takes place towards the end of the first irradiation phase, wherein the second irradiation phase immediately follows the first irradiation phase, and the sampling of the at least one emission spectral value takes place towards the end of the second irradiation phase, wherein the sampling sequence begins again after the end of the second irradiation phase or the sampling sequence comprises a rest phase which follows the second irradiation phase and in which the document of value is not irradiated by the checking sensor, wherein the sampling sequence begins again after the end of the rest phase and the sampling of the at least one spatially dependent emission spectral value takes place in the rest phase, preferably towards the end of the rest phase. - irradiating a checking region of the checking sensor which at least partially overlaps the security region with excitation radiation and checking radiation in a first irradiation phase, wherein the checking radiation is designed to be at least partially remitted by the document of value in a detection spectral range of the checking sensor, and the excitation radiation is designed to bring about emission radiation of the luminescence feature in the detection spectral range; - sampling at least one spatially dependent remission spectral value in the checking region in the first irradiation phase; - irradiating the checking region only with the excitation radiation in a second irradiation phase; - sampling at least one spatially dependent emission spectral value in the checking region after the first irradiation phase; and - performing an authenticity check according to which the document of value is classified as being genuine or not genuine on the basis of the at least one spatially dependent remission spectral value, which has been sampled multiple times in a spatially resolved manner, and of the at least one spatially dependent emission spectral value, which has been sampled multiple times in a spatially resolved manner, wherein the sampling of the at least one remission spectral value takes place towards the end of the first irradiation phase, wherein the second irradiation phase immediately follows the first irradiation phase, and the sampling of the at least one emission spectral value takes place towards the end of the second irradiation phase, wherein the sampling sequence begins again after the end of the second irradiation phase or the sampling sequence comprises a rest phase which follows the second irradiation phase and in which the document of value is not irradiated by the checking sensor, wherein the sampling sequence begins again after the end of the rest phase and the sampling of the at least one spatially dependent emission spectral value takes place in the rest phase, preferably towards the end of the rest phase.
