Abstract
The invention relates to a method for producing and verifying a non-personal access authorization means (1), and a corresponding access authorization means, especially an entrance ticket (1) for carrying out the method. The aim of the invention is to reduce the risk of such an access authorization means being produced fraudulently. To this end, the invention provides that the following steps are taken; application of biogenically structured material (3) to the access authorization means (1); defined determination of the characteristic parameters of said biogenic material (3); storage of the recorded parameter data in data sets; verification by defined measurement of the predetermined parameters and comparison of the parameter data with the available data sets; and authorization of entry when the defined match criteria are satisfied. The biogenic material (3) is preferably integrated into a material (2) which is transparent to the measuring process used.
