Claim One:
1. A method for checking including authenticity and the nominal value of a value document having luminescent feature substances, the value document being a non-transitory machine-readable medium, the method comprising: a1) the step of carrying out a location-specific measurement of first luminescence intensities (L1) at a first emission wavelength at different locations of the value document that have the location coordinates (O), to thereby obtain (O/L1) measurement value pairs; b1) the step of statistically analyzing the first luminescence intensities (L1) measured in dependence on the individual location coordinates (O), by determining at least one statistical parameter using a statistical method; and c1) the step of comparing the statistical parameter determined in the step b1) with one or more threshold values; wherein at least 20 (O/L1) measurement value pairs are evaluated per value document for determining the statistical parameter.
